Full textAbstract:
Dental implants are a proven therapeutic option for replacing missing teeth, with positive long-term health outcomes. Dental implant performance is largely determined by the implant’s primary durability, which is affected by surgical procedure, bone quality and quantity, implant surface characteristics, implant geometry, and implant surface characteristics. The implant’s geometry and surface can be modified. The implant geometry and surface can be changed if needed to achieve good primary stability and long-term implant therapy effectiveness. Implant architecture refers to the implant’s three-dimensional structure, as well as all of the components and elements that make it up. Different surface topographies can affect a sequence of coordinated actions such cell proliferation, osteoblast transformation, and the production of bone tissue. At the macro, micro, and increasingly nano sizes, surface topography of implants may be detected. The surgical location of end osseous oral implants is influenced by the prosthetic architecture, as well as the shape and quality of the alveolar bone. There are several alternatives for replacing missing teeth, but within the past few decades, dental implants have been one of the most common biomaterials for replacing one (or more) missing teeth. In a substantial number of patients, titanium dental implants have been shown to be secure and reliable. This study examines the most important historical information of dental implants, as well as the various vital factors that will ensure successful Osseo-integration and a safe prosthesis anchorage.

The lack of compatible prosthetic components can be a complication during oral rehabilitation using outdated implants. The aim of the present clinical report was to describe an alternative technique for the fabrication of a maxillary implant-supported overdenture in a patient with 20-year-old dental implants using castable spherical patterns and ball attachments. The patient had been wearing a relined bar/clip overdenture in the mandible on 4 external-hexagon dental implants and a relined complete denture in the maxilla on 4 internal-hexagon implants due to abutment screw fracture inside of the implants, losing the attachment system. The remaining maxillary dental implants did not possess attachments compatible with current systems due to configuration changes by the manufacturer in the dental implant's platform and the components over time. Therefore, castable spherical patterns and cast ball attachments were used to fabricate a maxillary implant-supported overdenture. The mandible rehabilitation was performed using 4 osseointegrated dental implants with a fixed implant-supported prosthesis. The use of cast ball attachments on the maxillary dental implants avoided invasive procedures on the remaining implants. Considering the lack of available compatible prosthetic components for the osseointegrated implants, this technique was considered a viable and satisfactory treatment option.

OBJECTIVE: To investigate the dental practitioner's knowledge, attitude and practice towards dental implants. METHODOLOGY: This study was carried out from May'2019 - Oct 2019. 752 dental practitioners who were currently practicing were included in the study. A well-structured questionnaire was used for data collection. SPSS-25 was used for statistical analysis. Spearman correlation was used to find the effect of gender, knowledge and attitude. The P <0.05 was considered statistically significant. RESULTS: In this study 80.9% dental practitioners were aware of the appropriate implant material while, 57.9% had knowledge about the types. 30.3% knew about the implant surface modifications whereas 46.1% dentists were aware of possible implant placement approaches. 49.3% believed that the distance between dental implants to be 3mm and between a dental implant and natural tooth to be 1.5 mm. 76% dentists claimed that dental implants have biomechanical complications. Whereas 67.8% knew about the Branemark's theory of osseointegration. Regarding the attitude of dental practitioners, 28.9% had received implant hands on trainings while 9% felt competent to place an implant. CONCLUSION: This study describes that dental practitioners had an appropriate knowledge of each aspect of implantology. Moreover despite the fact majority felt that they are not competent enough to practice it. Thus, it is important that the curriculum, teaching standards, the materials and methods regarding dental implants need to be reviewed and more exposure of hands-on workshops is to be provided not only for the graduates but also the undergraduates during their clinical learning.

Abstract Titanium and its alloys are widely used as dental implant materials due to their excellent biocompatibility, mechanical properties and erosion resistance. The b type titanium alloys are becoming more promising dental implant materials for their low elastic modulus and suitable mechanical properties. Because the titanium alloys are bioinert. The dental implant’s surfaces that contact with bone tissues need modification. To bioactivate the implants, hydroxyapatite/TiO2 composite material was coated onto dental implants by sol-gel and micro arc oxidation (MAO) methods. The HA (Hydroxyapatite) was employed to enhance the bioactivity of the Ti substrate. Owning to TiO2, the HA/TiO2 composite coatings adhered tightly to the dental implants and no longer existed cracks.

Abstract Titanium and titanium alloys are widely used for fabrication of dental implants. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies are being developed. However, these novel technologies must maintain the characteristics that provide titanium implants with their high success rates. Zirconia implants were introduced into dental implantology as an alternative to titanium implants. Zirconia seems to be a suitable implant material because of its toothlike color, mechanical properties, biocompatibility, and low plaque affinity. The aim of this study is to review clinical and research articles conducted on zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration and mechanical strength. Zirconia dental implants have the potential to become alternative dental implants to titanium dental implants, but they are not yet in routine clinical use.

INTRODUCTION: Identification of dental implant types can be a complex process for inexperienced health care professionals. Dental implants can have subtle differences in their morphology, which make it difficult to distinguish them from one another The unique appearance of dental anatomy and the placement of custom restorations ensure accurate identification of bodies or human remains when radiographic techniques are correctly applied. AIMS AND OBJECTIVES: To develop a radiographic dental implant guide for ten common dental implant types currently used in the Western Cape, South Africa; using their morphological characteristics observed on pantomographs. DESIGN: The methodology considered for this research study was a positivist approach through a quantitative, exploratory, non-experimental research design. METHODS: Ten commonly used dental implants were radiographed at straight tube (ST), off-centre (OC) and severe off-centre (SOC) angles to create a reference instrument Two reviewers used the morphologies of the different dental implant types, namely the apex, thread and neck, observed on ante-mortem pantomographs, and compared it to the appearance of the dental implants in the reference instrument to make a positive identification match. The straight tube image of all ten dental implant types in the reference instrument was used as the initial point of reference to positively identify the morphological characteristics of each dental implant type on the pantomographs. RESULTS: A total of 380 dental implants could be identified on 105 pantomographs reviewed. Of the 380 dental implants, 350 dental implants (91%) were identified as dental implant types listed in the reference instrument while 30 dental implants were identified as another type of dental implant type not listed in the reference instrument A total of 208 dental implants (54.2%) could be positively identified on the ante-mortem pantomographs using the straight tube images in the reference instrument. The morphological characteristics of the dental implant types were described using x-ray imaging of dental implants. The ten commonly used dental implants types could be positively identified by two independent reviewers and based on this a radiographic dental implant guide was developed. CONCLUSION: Each dental implant type had unique morphological characteristics as well as similarities which enabled distinction between the different dental implant types. The dental implant guide developed could be used by dentistry and radiography students. The dental implant guide may be useful in the field of forensic dentistry and forensic radiology.

Short dental implants have been successfully used to support single and multiple fixed reconstructions in atrophic jaws, despite an increased crown-to-implant ratio. The use of short dental implants allows the treatment of patients for whom complex surgical techniques cannot be performed for medical, anatomical, or financial reasons. Furthermore, the use of short dental implants in clinical practice reduces morbidity, cost, and treatment time and reduces the need for complex surgery. The aim of this review is to evaluate the survival rates of short and extra-short dental implants and to discuss the impact of an increased crown-to-implant ratio on biologic and technical complications.

Full textAbstract:
Today, an artificial tooth root called a dental implant is used to replace lost tooth function. Treatment with dental implants is considered an effective and safe method. However, in some cases, the use of dental implants had some failures. The success of dental implants is influenced by several biomechanical factors such as loading type, used material properties, shape and geometry of implants, quality and quantity of bone around implants, surgical method, lack of rapid and proper implant surface's integration with the jaw bone, etc. The main purpose of functional design is to investigate and control the stress distribution on dental implants to optimize their performance. Finite element analysis allows researchers to predict the stress distribution in the bone implant without the risk and cost of implant placement. In this study, the stresses created in the 3A.P.H.5 dental implant's titanium fixture and screw due to the change in abutment angles tolerance have been investigated. The results show that although the fixture and the screw's load and conditions are the same in different cases, the change of the abutment angle and the change in the stress amount also made a difference in the location of maximum stress. The 21-degree abutment puts the fixture in a more critical condition and increases the chance of early plasticization compared to other states. The results also showed that increasing the abutment angle to 24 degrees reduces the stress in the screw, but decreasing the angle to 21 degrees leads to increased screw stress and brings it closer to the fracture.

In oral rehabilitation with dental implants, severely resorbed alveolar ridges are a challenging problem due to the reduced height of the residual bone. Continuous search for minimally invasive procedures has resulted in the conception of reduced-length dental implants, decreasing the necessary amount of bone for implantation, thereby reducing the need of bone-grafts. Given the growing demand in the field of implant dentistry and the continuous development of surgical techniques, this study aimed to review the current literature on the predictability and success rate of short implants. Relevant articles published in the PubMed database between the years of 2004 and 2014 were selected using the following key-words: short dental implants, extra-short implants, survival rate, implant, mandible, maxilla, prognosis, implant survival, implant length. Based on the literature review, we concluded that short implants showed high predictability and high success rate in the short term, therefore they are one of the current options for the rehabilitation of atrophic alveolar ridges. Further longitudinal studies are necessary to define more reliably parameters for their proper use, ensuring the achievement of high success rates and survival rates with the use of this type of implant.o assess the attitude and practice of dental professionals towards using of advance radiographic technique.

The aim of this prospective cohort observational field trial was to examine 1-year survival and success rates of a recently introduced tapered implant system with switched platform conical abutments and to evaluate patient related outcomes of therapy. Partially edentulous patients aged between 18 and 75 years, with available bone height for dental implants ≥10 mm desiring to restore the missing tooth/teeth with implant supported restoration, were recruited by 7 periodontists in their respective private practices. Dental implants were installed according to standard implant therapy protocol. Three to 6 months postoperatively, after evaluating interim implant success, implants were restored by the referring dentists. Patient, Ramfjord teeth, and implant data, including baseline and 1-year postoperative, were collected. A total of 60 patients were recruited and received 117 implants. Complete 1-year clinical and radiographic data were available for 83 and 65 implants, respectively. Two implants failed during the first year, resulting in a 1-year survival rate of 98.3%. Mean implant probing pocket depth was 2.29 ± 0.84 mm. Mean radiographic bone distance from implant's shoulder at the mesial and distal sites at 1 year was 0.66 ± 0.5 and 0.79 ± 0.64mm, respectively, resulting in a success rate of 95.4%. Patient subjective evaluation of therapy exhibited a median pain experience of 1 and median esthetics, function, and general satisfaction evaluation of 10 on a scale of 1 to 10. The tapered conical connection dental implant system, used in private dental practices, shows good 1-year survival and success rates that are similar to other implant systems on the market.

Purpose. To investigate effects of number and location on patterns of von Mises stress distribution and volume average stress on abutment tooth, edentulous ridge, mini dental implant, and surrounding bone of mini dental implant-assisted mandibular Kennedy class I removable partial denture. Materials and Methods. Eight three-dimensional finite element models of mandibular Kennedy class I with different numbers and locations of mini dental implants were constructed. Mini dental implants were generated in the area of second premolar, first molar, and second molar, respectively. A static load of 400 N was applied on all models. The von Mises stress and volumetric average stress were calculated by three-dimensional finite element analysis. Result. The minimum volumetric average stress of abutment tooth was found in the model, where there was one mini dental implant at the second molar position and 2 mini dental implants at first molar and second molar positions. The model with three mini dental implants had reduced volumetric average stress of abutment tooth, which was not different from the model with two mini dental implants. However, the minimum volumetric average stress of mini dental implant and surrounding bone were found when three mini dental implants were applied, followed by two and one mini dental implants, respectively. Conclusion. Placing at least one mini dental implant at a second molar position can help reduce stress transferred to the abutment tooth. Stresses around each implant and surrounding bone reduced with increased numbers of mini dental implants.

The aim of this study was to review the literature on the systems used to decontaminate the implant’s surface. Different instruments have been proposed, but there is no agreement in the literature about which methods would be more efficient with no damage to the implant surface. It was reported the use of plastic, carbon fiber, stainless-steel and titanium curettes and also the use of other systems such as ultrasonic points with different tips, rubber cups and air abrasion. Literature review: In most of the studies, the injury caused on the titanium surface at the time of instrumentation was examined. In others, the cell adhesion on the titanium dental implants following instrumentation of the implant surface was observed. Moreover, to enhance cleaning around implants, ultrasonic systems were recently tested. Conclusion: Metal instruments can lead to major damage to implant surface, therefore, they are not indicated for decontamination of dental implants surfaces. Furthermore, non-metallic instruments, such as plastic curettes, rubber cups, air abrasion and some ultrasonic systems seem to be better choices to remove calculus and plaque of the sub- and supra-gingival peri-implant area. It is noteworthy that more studies evaluating the effects of these systems are required to establish best practices to be used in the treatment of patients with dental implants.

Objectives: The demand for dental care is expected to increase as the population ages. This study aimed to predict the utilization of dental implant care following the expansion of national health insurance benefits for dental implants. Methods: Multiple linear regression analysis was performed on HIRA big data open portal data and DNN-based artificial intelligence models to forecast the utilization of dental care in relation to the national health insurance coverage for dental implants. Results: National health insurance coverage of dental implants was found to be associated with the number of patients using dental implant services and demonstrated a statistical significance. The dental implant services utilization increased with the increased dental implant health insurance benefits for the elderly population, increased mean by region, increased number of dental institutions by region, and increased health insurance coverage rate for dental implants. However, the dental implant services utilization decreased with the increased number of older people living alone and increased size of dental institutions. Conclusions: With the expansion of the national health insurance coverage for dental implants, it is predicted that the utilization of dental implant medical services will increase in the future.

Background & Objectives: The use of dental implants in partially or completely edentulous patients has proved effective and an accepted treatment modality with predictable long-term success. Dental implants are becoming a popular choice for replacing the missing teeth because of increased awareness about implants both in dentists and patients. The objective of the study was to assess the basic knowledge and education about dental implants among general dental practitioners (GDPs) of Nepal.Materials & Methods: A cross sectional questionnaire was carried out among 110 GDPs which consist of twenty questions that were divided into three categories; first with some basic knowledge in implant dentistry, second with clinical knowledge of dental implants and third with dental implant education and training.Results: Out of 110 GDPs, 72.7% had basic knowledge about implant dentistry and 65.5% were not aware about advance surgical procedures like sinus lift and guided bone regeneration. All the GDPs were positive regarding more training and education in dental implants and 95.5% of them would like to incorporate dental implant treatment in their practice in future. Conclusion: GDPs should have adequate knowledge and training of dental implants which can be incorporated at undergraduate or post doctoral level so that they are skilled to provide quality dental implant therapy to their patients confidently.

The number of supporting dental implants is an important criterion for the surgical outcome of dental bridge fixation, which has considerable impact on biomechanical load transfer characteristics. Excessive stress at the bone–implant interface by masticatory loading may result in implant failure. The aim of this study was to evaluate the impact of the number of implants supporting the dental bridge on stress in neighboring tissues around the implants. Results of the study will provide useful information on appropriate surgical techniques for dental bridge fixation. In this study, osseointegrated smooth cylindrical dental implants of same diameter and length were numerically analyzed, using three-dimensional bone–implant models. The effect of the number of supporting implants on biomechanical stability of dental bridge was examined, using two, three and four supporting implants. All materials were assumed to be linearly elastic and isotropic. Masticatory load was applied in coron-apical direction on the external part of dental bridge. Finite Element (FE) analyses were run to solve for von Mises stress. Maximum von Mises stresses were located in the cervical line of cortical bone around dental implants. Peak von Mises stress values decreased with an increase in the number of implants that support the dental bridge. Results of this study demonstrate the importance of using the correct number of supporting implants to for dental bridge fixation.

Achieving primary stability in dental implants is crucial factor for accomplishing successful osteointegration with bone. Micro-motions higher than the threshold of 50 to 100 μm can lead to formation of fibrous tissue at the bone-to-implant interface. Therefore, osteointegration may be vitiated due to insufficient primary stability. Osseointegration is defined as a direct and functional connection between the implant biomaterial and the surrounding bone tissue. Osseointegration development requires an initial rigid implant fixation into the bone at the time of surgery and a secondary stage of new bone apposition directly onto the implant surface. Dental implants function to transfer the load to the surrounding biological tissues. Due to the absence of a periodontal ligament, its firm anchorage to bone, various forces acting on it and the presence of prosthetic components, they share a complex biomechanical relationship. The longevity of these osseointegrated implants depend on optimizing these complex interactions. Hence, the knowledge of forces acting on implant, design considerations of implant and bone mechanics is essential to fabricate an optimized implant supported prosthesis.

The long-term clinical success of dental implants is related to their early osseointegration. This paper reviews the different steps of the interactions between biological fluids, cells, tissues, and surfaces of implants. Immediately following implantation, implants are in contact with proteins and platelets from blood. The differentiation of mesenchymal stem cells will then condition the peri-implant tissue healing. Direct bone-to-implant contact is desired for a biomechanical anchoring of implants to bone rather than fibrous tissue encapsulation. Surfaces properties such as chemistry and roughness play a determinant role in these biological interactions. Physicochemical features in the nanometer range may ultimately control the adsorption of proteins as well as the adhesion and differentiation of cells. Nanotechnologies are increasingly used for surface modifications of dental implants. Another approach to enhance osseointegration is the application of thin calcium phosphate (CaP) coatings. Bioactive CaP nanocrystals deposited on titanium implants are resorbable and stimulate bone apposition and healing. Future nanometer-controlled surfaces may ultimately direct the nature of peri-implant tissues and improve their clinical success rate.

ABSTRACT This study addresses the durability and complications of zirconia dental implants through a prospective clinical investigation. Zirconia implants are increasingly utilized in dental implantation, and a comprehensive understanding of their long-term performance is essential. Background: Zirconia dental implants have gained attention due to their biocompatibility and aesthetics. However, research on their extended success and complication rates is limited. Materials and Methods: A prospective clinical study involved the placement of 30 zirconia dental implants in patients requiring tooth replacement. The implants were followed up for five years. Success was defined as the implant remaining stable and functional. Complications, including peri-implant mucositis and peri-implantitis, were monitored. Statistical analysis included descriptive statistics, Chi-square test, and P-values were set at P < 0.05. Results: The long-term success rate of zirconia dental implants was found to be 93.3%. Among the 30 implants, only 2 exhibited failure. The most common complication was peri-implant mucositis, occurring in 16.7% of implants. Notably, the incidence of peri-implantitis was limited, observed in 6.7% of implants. Statistical analysis showed significant associations between implant failure and smoking (P = 0.021). Conclusion: Zirconia dental implants demonstrated a high long-term success rate of 93.3% over five years. Peri-implant mucositis was the predominant complication, with a relatively low occurrence of peri-implantitis. The findings underscore the potential of zirconia implants for reliable dental implantation. Addressing modifiable risk factors, such as smoking, could further enhance implant success. Continued research is recommended to validate and expand upon these outcomes.

Preserving the marginal bone level (MBL) is essential for the long-term success of dental implant therapy, and bone remodeling around dental implants is considered to vary with time. Numerous studies comparing the platform-switching (PS) and platform-matching (PM) dental implants have indicated that PS dental implants showed a lesser reduction for the MBL, and the majority of them had a relatively short period. This study aimed to evaluate vertical and horizontal bone defects by using digital periapical radiographs to examine the changes in MBL around PM and PS dental implants over 5 years after functional loading. The vertical MBL (vMBL) was measured from the implant–abutment junction to the first bone-to-implant contact. The horizontal MBL (hMBL) was measured from the implant–abutment junction to the bone crest. All data were presented as means ± standard errors. Paired and independent t-tests with Welch’s correction were used to analyze the data. A total of 61 dental implants in 38 patients after 5 years of functional loading were evaluated. Over time, PS dental implants were more likely to gain bone; by contrast, PM dental implants were more likely to lose bone during the observation time. Changes in vMBL for PS dental implants were significantly less than those for PM dental implants at 1-year (p = 0.045), 3-year (p = 0.021), and 5-year (p = 0.010) loading. Likewise, changes in hMBL for PS dental implants were significantly smaller than in those for PM dental implants at 3-year (p = 0.021) and 5-year (p = 0.006) loading; however, the changes were minimal in both approaches. PS dental implants had a significant increment in the percentage of bone integration, whereas that for PM dental implants dropped over time, with no significance. In PS dental implants that occlude with natural teeth, vertical and horizontal bone gain was observed, and it was significant at 3 years (p = 0.023). A significant horizontal bone gain was observed in the opposing natural teeth at 3-year (p = 0.002) and 5-year loading (p = 0.002). The PS concept appears to preserve more MBL around dental implants by stabilizing the vMBL and hMBL over a 5-year period. A minimal marginal bone change was detected in both concepts. The opposing natural teeth at PS dental implants showed a favorable effect on marginal bone tissues.

A high number of patients have one or more missing tooth and it is estimated that one in four world subjects over the age of 74 have lost all their natural teeth. Many options exist to replace missing teeth but dental implants have become one of the most used biomaterial to replace one (or more) missing tooth over the last decades. Therefore, the use of dental implants is also a common practice. Although research on dental implant designs, materials and techniques has increased in the past few years and is expected to expand in the future, there is still a lot of work involved in the use of better biomaterials, implant design, surface modification and functionalization of surfaces to improve the long-term outcomes of the treatment. This paper provides a brief history and evolution of dental implants. It also describes the types of implants that have been developed, and the parameters that are presently used in the design of dental implants. Finally, it describes the trends that are employed to improve dental implant surfaces, and current technologies used for the analysis and design of the implants. Keywords: Dental implants, History, Design, Surfaces, Osseointegration, Biopolymers.

ABSTRACT Introduction Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. Materials and methods In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan–Meier survival analyses and chisquare test were used for assessment of level of significance. Results In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. Conclusion Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. Clinical significance Delayed loaded dental implant placement should be preferred as they are associated with decreased risk of implant failure.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap technique was 1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

Many patients travel abroad seeking cosmetic dental treatment, in particular dental implants. However, there are hundreds of dental implant systems being used globally by dentists of all training backgrounds. Furthermore, complications can occur that patients may expect their general dental practitioner in the UK to be able to manage. The following report describes the case of a 71-year-old, medically compromised patient who presented with complaints consistent with the immediate failure of dental implants that happened to be placed abroad. On closer examination, the dental implants themselves were highly questionable in their design and placement. An incidental finding was also made in the maxillary sinus. CPD/Clinical Relevance: To acknowledge that implant dentistry is increasing in popularity as patients have the freedom to access dental implant treatment globally. UK dentists are expected to manage these dental implants on the return of patients to the UK who may present with post-operative complications involving unknown dental implant systems.

Our purpose was to evaluate the occurrence of complications and the degree of bone loss in a cohort of patients treated with fixed prostheses supported by immediately loaded dental implants. The primary aim was to compare partial versus full-arch fixed dental prostheses. We then tested the effect of sinus lifting. In the present retrospective cohort study, the patients had their implants restored with fixed dental prostheses supported by dental implants positioned in the posterior maxilla and mandible. When necessary, the maxillary sinuses were grafted with particulate autogenous bone. Patients were then ranked according to the following predictors: length of prosthesis, crown-to-implant ratio, number of crowns to number of implants ratio, and presence of sinus lifting. Outcomes were evaluated for up to 2 years regarding the peri-implant marginal bone loss and implant/prosthesis survival rates. Fifty-eight subjects (209 implants) were rehabilitated with 25 fixed full-arch prostheses and 33 partial fixed dental implant bridges (16 supported by implants placed in grafted sinus). The mean marginal bone loss for implants supporting partial fixed dental prostheses amounted to 0.81 mm, whereas that for implants within the group of full-arch fixed dental prostheses was 1.21 mm; the comparison of the levels in the 2 groups showed a significant difference (P = .0055). A statistically significant difference (P = .0006) was found between the bone loss around maxillary implants (1.53 mm) and the bone loss around mandibular implants (1.10 mm). Two implants and 4 prostheses failed; 2-year survival rates of partial and of full-arch fixed dental prostheses, respectively, were 94.1% and 96%. Bone loss in full-arch prostheses appeared to be higher than in that of partial prosthesis. Implant-supported prostheses in the maxillae exhibited a bone loss higher than that registered in mandibles.

Dental implant therapy is a well-accepted treatment modality. Despite good predictability and success in the early stages, the risk of postplacement inflammation in the long-term periods remains an urgent problem. Surgical access and decontamination with chemical and mechanical methods are more effective than antibiotic therapy. The search for the optimal and predictable way for peri-implantitis treatment remains relevant. Here, we evaluated four cleaning methods for their ability to preserve the implant’s surface for adequate mesenchymal stem cell adhesion and differentiation. Implants isolated after peri-implantitis were subjected to cleaning with diamond bur; Ti-Ni alloy brush, air-flow, or Er,Cr:YSGG laser and cocultured with mice MSC for five weeks. Dental bur and titanium brushes destroyed the implants’ surfaces and prevented MSC attachment. Air-flow and laser minimally affected the dental implant surface microroughness, which was initially designed for good cell adhesion and bone remodeling and to provide full microbial decontamination. Anodized with titanium dioxide and sandblasted with aluminum oxide, acid-etched implants appeared to be better for laser treatment. In implants sandblasted with aluminum oxide, an acid-etched surface better preserves its topology when treated with the air-flow. These cleaning methods minimally affect the implant’s surface, so it maintains the capability to absorb osteogenic cells for further division and differentiation.

ABSTRACT Background Treatment with dental implants has become increasingly important in the range of prosthodontic treatment. Significant improvements in oral rehabilitation particularly in edentulous individuals have been seen. In Adhiparasakthi Dental College, Melmaruvathur, a survey was made to evaluate awareness among patients for dental implants, their level of knowledge, and attitude toward replacement of missing teeth by dental implants. Materials and methods A survey of 480 people was conducted through a printed questionnaire and completed by willing respondents. The questionnaires were prepared in English and Tamil language to enable better understanding and completion. Results Of the 510 people surveyed, 480 responses were retrieved, of which 331 were aware of dental implant treatment in Melmaruvathur, Tamil Nadu. Among them, 304 respondents were aware that implants could be used for replacement of missing teeth. Most of the respondents stated that dental implants were placed in the jawbone, followed by gums. Only 41% respondents assumed that implants last for a lifetime and only 35% of respondents believe that poor oral hygiene was the most common cause of implant failure. Conclusion More dental education programs are needed to improve understanding of the importance of restoration of missing teeth. General implant awareness levels are satisfactory. However, increased awareness of patients for restoration of missing tooth with dental implants is necessary. Dental education programs with special emphasis on advantages, treatment, maintenance, and postoperative care of dental implant therapy are needed. More than two-thirds of the surveyed population is interested in knowing about and being treated with dental implants. How to cite this article Narayanan V, Karuppiah P, Rajasekar A, Mayavan LD.

Purpose. Evaluate the effect of different mini-implant numbers on overdenture retention and evaluate attachment wear following one year of simulated placement/removal. Material and Methods. Nine models simulating atrophic mandibles held 27 mini dental implants in three groups of 2, 3, and 4 mini-implants. A total of 1080 simulated placement/removal cycles were carried out, and a digital force gauge was used to measure the overdenture dislodgment force. The means of the retention forces were analyzed using SPSS with one-way ANOVA and post hoc ( p < 0.05 ). The inner diameter of attachment inserts was evaluated using a light microscope before and after testing. A paired t -test was used to compare the mean of inner ring diameters ( p < 0.05 ). Results. The retention was significantly reduced regardless of the mini dental implant number, but the number affected overdenture retention. The placement of 4 mini dental implants provided higher retention and less reduction in retentiveness. However, no significant difference was found when 3 mini dental implants were compared to 2 mini dental implants ( p = 0.21 ). Microscopic examination showed abrasion wear in all inserts following testing. However, the inserts of the 4 mini dental implants showed less wear than those used for 2 or 3 mini dental implants with p ≤ 0.001 and p ≤ 0.001 , respectively. Conclusion. Mini dental implant overdenture retention force and attachment wear could improve by increasing the mini dental implants to 4. However, there was no difference in retention force or attachment wear when 2 or 3 mini dental implant overdentures were compared.

The aim of this study was to evaluate the stress distribution in the bone around dental and zygomatic implants for 4 different implant-supported obturator prostheses designs in a unilaterally maxillary defect using a 3-dimensional finite element stress analysis. A 3-dimensional finite element model of the human unilateral maxillary defect was constructed. Four different implant-supported obturator prostheses were modeled; model 1 with 2 zygomatic implants and 1 dental implant, model 2 with 2 zygomatic implants and 2 dental implants, model 3 with 2 zygomatic implants and 3 dental implants, and model 4 with 1 zygomatic implant and 3 dental implants. Bar attachments were used as superstructure. A 150-N vertical load was applied in 3 different ways, and von Mises stresses in the cortical bone around implants were evaluated. When the models (model 1–3) were compared in terms of number of implants, all of the models showed similar highest stress values under the first loading condition, and these values were less than under model 4 conditions. The highest stress values of models 1–4 under the first loading condition were 8.56, 8.59, 8.32, and 11.55 Mpa, respectively. The same trend was also observed under the other loading conditions. It may be concluded that the use of a zygomatic implant on the nondefective side decreased the highest stress values, and increasing the number of dental implants between the most distal and most mesial implants on the nondefective side did not decrease the highest stress values.

In a daily routine practice dental implants has been widely used and dental implants are considered as a one of the good treatment option in replacing the single tooth in the oral cavity or replacing the multiple teeth in the oral cavity. With the use of dental implants, a dentist can replace the single tooth or multiple teeth or with the help of dental implants one can provide the whole full arch implant supported prosthesis. The survival rate of the implants are dependent on so many conditions , like patient systemic condition, bone quality and amount of bone available, sterilization protocol during the placement of the implant. In some cases failing of implant were also seen due to systemic condition, due to mechanical failure such as loosening of the implant, loosening of the screw. So a dentist should have a basic knowledge of the implant along with its all components, causes of implant failures and how to avoid the causes of implant failure as well as how to manage.

One of the recent advances in the field of dentistry is to provide prothesis that can replace lost natural teeth. Over several decades, researches were endeavouring to create dental implants with optimized criteria that allow long-term function and stability. After notable success, the use of dental implant has become an almost daily routine in dental practice. However, many factors can influence the success of dental implantation procedures. Primary implant stability remains the most reliable predictor of dental implants success, and many factors are known to have a considerable impact on the implant stability such as the thread morphology, the implant size and length, the implant body shape, the surgical technique use, and the underlying bone heath. Knowledge of these factors is essential for optimizing the outcome of dental implantation procedures even in unfavourable conditions. Therefore, this article aims at reviewing and discussing the various dental implants designs, characteristics, and stability.

Data on dental implant treatment's success and survival rate are still limited. Meanwhile, the data on the success and survival after implant placement and restoration can be used to evaluate materials, improve the dental implant treatment, and enhance the service quality at Hasanuddin University Dental Hospital. The purpose of this study is to analyze the dental implant survival rate, the contributing factors that enhance the survival rate, and the factors causing the failure of the dental implants at the Prosthodontic Clinic of Dental and Oral Hospital, Hasanuddin Uni-versity. The final study group consisted of 11 patients with 20 implants. Implant failure was categorized based on implant loss, mobility, or removal due to severe peri-implant infection or implant fracture. Implant survival rates were grouped based on sex, age, smoking habit, placement location, diameter, length, and placement time. The value of implant survival rate was assessed based on the presentation of successful implants. Of all 20 cases, five implants failed, indicating a cumulative implant survival rate of 75%. Based on the failure period, there are initial failure cases before loading and late failure cases after loading. One implant failed within the first six months, and two implants failed 2 years after insertion of the superstructure. The leading cause of implant failure before loading is osseointe-gration failure. In the case of implants that failed after installing the superstructure, peri-implantitis occurs continous-ly. It was concluded that the implant survival rate for patients at the Hasanuddin University Dental Hospital is 75%. Dental implant survival rates include gender, age, implant placement location, smoking habits, implant diameter, length, and immediate or delayed implant placement. The factors causing the failure of the implant in this study were osseointegration failure and peri-implantitis

Additive manufacturing, commonly known as 3D printing technology, has become a prominent topic of research globally in recent years and is playing an increasingly important role in various industries. Particularly within the healthcare sector, the use of 3D printing technology is gaining prominence, with a special focus on the manufacturing and application of dental implants. As research in this field progresses, the preparation methods, material selection, and technological innovations for dental implants are evolving, promising a future where the manufacturing process of dental implants becomes even more refined and efficient. Through thorough research in materials science, it is possible to develop dental implant materials that have better biocompatibility with the human body and improved mechanical properties. Additionally, advancements in surface modification technology can further enhance the strength and stability of the bond between dental implants and bone tissue. These advancements not only expand treatment options for patients but also greatly improve the long-term success rate of dental implants. In the field of dental implants, the success of the implant depends on the interactions between the materials used, the cells involved, and the bone tissue. Therefore, there is an urgent need to explore the molecular mechanisms of such interactions in depth. In this study, we provide a comprehensive review of the application of 3D printing technology in the fabrication of dental implants. This includes an examination of the process methods, surface coating technology, and a comparison of the shapes and structures of different dental implants, along with their advantages and disadvantages. Furthermore, this paper analyzes the intrinsic mechanisms of successful dental implant placement in clinical practice, and it highlights the latest progress in the clinical application of 3D-printed dental implants. Undeniably, the use of 3D-printed dental implants not only offers patients more precise and personalized treatment plans but also brings revolutionary changes to the development of the medical industry.

Dental implants, or completely said as dental implant bodies, function as analogues of tooth roots, achieving aunion directly with jawbone following their insertion into a prepared socket in the bone. Implant system have threebasic components, namely the dental implant body that is lying in the jawbone, abutment that lies on the jawboneand the prosthesis. Dental implants may stabilize a removable prosthesis, complete or partial overdentures, and orsupport and stabilize a fixed prosthesis. In designing implant-supported removable prostheses, there are three formsof anchorage frequently used, namely bar/sleeve (clip) joints which links two or more implants, ball/cap anchoragesapplied individually to two or more isolated implants, and magnets/magnetic keepers. Implant-supported fixedprosthesis is either screwed to or cemented on to the abutment.

The variables assessed included the plaque level, bleeding on probing, probing depth, implant mobility, implant stability, and implant loss. To analyze the peri-implant bone level, a panoramic X-ray of each patient was taken. The results were compared with X-rays taken immediately after implantation.Results. Thirty-seven patients (16 males; 21 females) participated in this study. In total, 155 implants (86 maxillary; 69 mandibular) were inserted. Two of the 155 implants failed; thein situsurvival rate was 98.7%. The success rate according to the criteria of Buser et al. was 96.8%, and that according to the criteria of Albrektsson et al. was 88.4%.Conclusion.The survival and success rates of dental implants in patients with congenitally absent teeth were very high and did not differ significantly from results achieved in an unaffected population. Dental implants are a reliable therapy for patients with dental aplasia.

The aim of the study is to determine patients’ knowledge and attitudes toward dental implants as a therapeutic option after tooth extraction and to examine the sources of information about dental implants and determine the most common barriers in deciding for this type of therapy. The cross-sectional study included 130 patients. An anonymous survey questionnaire was used to conduct the research. The survey questionnaire consists of a total of 17 multiple-choice questions. Respondents showed good knowledge of dental implants except for knowledge of dental implant duration where subjects mostly stated that a dental implant lasts a lifetime. For most respondents, the dentist is the main source of information related to dental implants. The cost of the procedure for most respondents is a major barrier in decision to install a dental implant, but most of them want to know more about dental implants. Statistically significant differences were observed in patients ‘knowledge in relation to age and level of education and patients’ attitudes in relation to gender, age, and level of education.

Background. Improving the implantation conditions in order to reduce the failure is always desirable for researchers. The aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order to introduce a novel simulation method to select suitable materials for dental implants. Methods. In this research, drilling process was performed in the cortical bone of the mandible by finite element analysis simulation. Then, a 3D model of the produced hole in the drilled site was derived and a dental implant model by ITI design was inserted into the cavity. The space remaining between the implant and cavity was considered as a newly formed cortical bone area. Implant loading was performed on two dental implants with different types of material. The change in the volume of the cortical bone around each implant was considered a criterion for evaluating bone damage. Additionally, the micromotion of dental implant in the mandible after implantation was used for investigating dental implant stability. Results. After implant loading, the volume changes in newly formed cortical bone around Ti and Zr-2.5%Nb dental implants were measured at 0.010809 and 0.010996 mm3 , respectively. Furthermore, micromotion of Ti and Zr-2.5%Nb dental implants were measured at 0.00514 and 0.00538 mm, respectively. Conclusion. This study showed that Ti dental implant creates better conditions than Zr-2.5%Nb dental implant in the maxillofacial region

Dental implants have become an increasingly prevalent treatment option for the replacement of missing teeth. Multiple studies have reported survival rates for implant supported restorations above 90% after 10 years. However, dental implants are not without complications and with their increasing placement, it is more likely that primary care dentists and dental care professionals will encounter patients presenting with problems. The first article in this two-part series provides an overview of implant components and relevant anatomy, as well as outlining a systematic method of undertaking a clinical and radiographical examination of dental implants. CPD/Clinical Relevance: This series highlights important aspects of dental implants and their associated restorations that dental care professionals should consider when examining and maintaining such restorations, as well as providing an overview of associated biological and mechanical complications.

Purpose. To investigate peri-implant alveolar bone changes using periapical radiographs before and after prosthetic delivery in submerged and nonsubmerged dental implants. Methods. Digital periapical films of 60 ITI Straumann nonsubmerged dental implants and 60 Xive Dentsply submerged dental implants were taken before, immediately after, and 12 and 24 weeks after the prosthetic restoration was delivered. Results. The 60-nonsubmerged dental implant group showed mean marginal bone resorption at baseline of 0.10 ± 0.23 mm and 24 weeks later, marginal bone resorption was 0.16 ± 0.25 mm. The submerged dental implant group showed a significantly higher distal marginal bone resorption over the mesial side. Mean marginal bone resorption at baseline was 0.16 ± 0.32 on the mesial and 0.41 ± 0.56 on the distal side. Twenty-four weeks later, it was 0.69 ± 0.69 mm on the mesial and 0.99 ± 0.90 mm on the distal side. Conclusion. First, it was possible to determine that submerged implants had a higher mean marginal bone resorption and less bone-to-implant contact than nonsubmerged implants. And second, the distal side of submerged dental implants presented higher marginal bone loss than the mesial side.

Full textAbstract:
Dental implants are frequently used to support fixed or removable dental prostheses to replace missing teeth. The clinical success of titanium dental implants is owed to the exceptional biocompatibility and osseointegration with the bone. Therefore, the enhanced therapeutic effectiveness of dental implants had always been preferred. Several concepts for implant coating and local drug delivery had been developed during the last decades. A drug is generally released by diffusion-controlled, solvent-controlled, and chemical controlled methods. Although a range of surface modifications and coatings (antimicrobial, bioactive, therapeutic drugs) have been explored for dental implants, it is still a long way from designing sophisticated therapeutic implant surfaces to achieve the specific needs of dental patients. The present article reviews various interdisciplinary aspects of surface coatings on dental implants from the perspectives of biomaterials, coatings, drug release, and related therapeutic effects. Additionally, the various types of implant coatings, localized drug release from coatings, and how released agents influence the bone–implant surface interface characteristics are discussed. This paper also highlights several strategies for local drug delivery and their limitations in dental implant coatings as some of these concepts are yet to be applied in clinical settings due to the specific requirements of individual patients.

INTRODUCTION. Osseointegrated implants are actually replacements for natural teeth, and, like natural teeth, they are exposed to various forces. Rejection and bad osseointegration of implants rarely occur today because oral implants are made from biocompatible materials. Most complications are a consequence of badly planned implant loading. OBJECTIVE. The aim of this work was the optimization of the process of planning and inserting oral implants and dentures based on the analysis of the biomechanical problems in implantology. METHOD. In order to determine the influence of the number of cantilevered superstructures, the number of implants and implant microdesign on tensions within the implant and in the peri-implant tissue, a calculation of tensions and deformations was made in a virtual model (control model) using the finite elements analysis. The obtained values served as reference values in the analysis of the results from three experimental models. RESULTS. In the control model, as well as in the experimental models, the first implant bears the heaviest load with dominant contraction tensions, the second one carries significantly weaker straining tensions, the third one carries weak contraction tensions and the fourth one the weakest straining tensions. The values of tensions and deformations have the same sign (-/+), but the absolute values depend on the number of cantilevered superstructures, implant microdesign and the number of inserted implants. CONCLUSION. Knowing the biomechanics of oral implants and the dentures on them allows for proper indication, a good choice of implants and good superstructure design. The prevention measures for bone resorption caused by biomechanical factors are: insertion of symmetrical screw implants and root-shaped cylindrical implants as long and as wide as possible, insertion of implants with the total supporting area expanded, choosing materials that are rigid enough, the right direction of implants, narrowing of the denture occlusal surfaces and location of the contact point at the centre.

Titanium dental implants are one of the modalities to replace missing teeth. The release of titanium particles from the implant’s surface may modulate the immune cells, resulting in implant failure. However, little is known about the immune microenvironment that plays a role in peri-implant inflammation as a consequence of titanium particles. In this study, the peri-implant gingival tissues were collected from patients with failed implants, successful implants and no implants, and then a whole transcriptome analysis was performed. The gene set enrichment analysis confirmed that macrophage M1/M2 polarization and lymphocyte proliferation were differentially expressed between the study groups. The functional clustering and pathway analysis of the differentially expressed genes between the failed implants and successful implants versus no implants revealed that the immune response pathways were the most common in both comparisons, implying the critical role of infiltrating immune cells in the peri-implant tissues. The H&E and IHC staining confirmed the presence of titanium particles and immune cells in the tissue samples, with an increase in the infiltration of lymphocytes and macrophages in the failed implant samples. The in vitro validation showed a significant increase in the level of IL-1β, IL-8 and IL-18 expression by macrophages. Our findings showed evidence that titanium particles modulate lymphocyte and macrophage polarization in peri-implant gingival tissues, which can help in the understanding of the imbalance in osteoblast–osteoclast activity and failure of dental implant osseointegration.

Aim: Dental implant failure might be brought on by an early postoperative infection. The purpose of this study was to assess the prevalence of acute postoperative infection in survived and failed implants and the associated factors. Methods: This cohort cross-sectional study held in the Oral surgery department of Altamash Institute of Dental Medicine, Karachi for two-years duration from January 2021 to December 2022 and evaluate early postoperative infection after dental implant surgery. The location of the implant, the patients' ages and genders, smoking, postoperative antibiotic therapy, bone augmentation and the time of infection development or diagnosis were among the study variables. The study's results showed which implants failed and which survived. Two groups of patients; those who survived implants included in Group A and those who had failed implants were included in group B. Results: Out of 190 patients, 12 (6.3%) patients, including 8 men and 4 women, experienced a postoperative infection after implant insertion. In group A of implant survival, 5 implants (41.7%) acquired post-operative infection while 7 implants (58.3%) in the failed group experience infections. The significant variations among the both groups were noted in terms of the smoker patients, the timing of diagnosis, patients who got bone transplant and fresh socket versus delayed implant placement. Relating to the variables, the Kaplan-Meier analysis revealed that when infection developed 4 days after surgical procedure in subjects not given antibiotic treatment postoperatively, the probability of implant failure increased by 1.1 times (hazard ratio). If the infection developed after six days in people who smoked and after nine days in people who do not smoked and were given antibiotics postoperatively, the likelihood of failure rose. Conclusion: In light of the study's findings, it appears that smoking, early infection, implants placement in newly created sockets, and implants placement in conjunction with bone substitutes may all enhance the failure ratio of dental implants following acute infection. Keywords: antibiotic, implant, infection, and bone

The potential impact of injectable platelet-rich fibrin (I-PRF) combined with bone graft as a guided bone regeneration on the relationship between dental implant stability, alveolar ridge width, and dental implant dimension. Materials and methods: The present prospective comparative study was registered at ClinicalTrials.gov (ID number: NCT05427643). A total of 13 patients aged 18-65 years (11 females and 2 males) presented with missing teeth in either the maxilla or the mandible or both and met the eligibility criteria and enrolled in this study treated with 40 dental implants. These cases were allocated into two groups, control group in which the implants were placed without I-PRF and a study group (advanced cases with narrow alveolar ridge) in which implants were installed with I-PRF mixed with synthetic bone graft at the dehiscence sites around the implants. 22 (55%) dental implants were inserted in patients with alveolar bone width of ˂ 3.5 mm and 18 (45%) dental implants were inserted in ridge with ≥ 3.5 mm. The primary stability was measured at the time of surgery and Secondary stability was measured 24 weeks after dental implant installation with Anycheck device in implant stability test (IST) values. Results: Twenty dental implants were installed in each study group. According to the results obtained in this study, there was significant difference between primary stability (69.96±8.5 vs 74.50±4.3) of both groups and secondary stability (69.96±8.5 vs 76.32±6.5) values of group A with bone width of ≥ 3.5 mm and dental implant dimension 4.1 mm. Conclusion: The addition of I-PRF with bone graft for augmentation of dehiscence and fenestration peri-implant defects with simultaneous implant placement results in 100% survival rate with statistical differences in implant secondary stability between study groups. However, the results were clinically irrelevant.

AbstractBackground: Dental implants are useful tools and represent a widely spread technique for oral rehabilitation. Their long standingness is highly influenced by the mechanical and geometrical properties of the surrounding osseous tissue in which they are placed. In some unsuccessful cases though, the dental implant is exposed to masticatory forces and other functional acts, and osseous tissue may resorb near its vicinity, leading to the dental implants loss. We investigated the strain distribution inside the fixating substrate, given certain stages of its deterioration near the dental implants.Material and methods: For our investigations we used cilindro-conical screw-type dental which were submitted to vertical forces between 0-1000 N. The dental implants were fixed inside a plastic material used in photo-elastic measurements.To evaluate the strain distribution inside the fixing substrate, we used a non-contact, experimental investigation tool, the Video Image Correlation (VIC-3D) optical system. This system allows the implementation in the dental implants optimisation from stress-strain state point of view.Results: The strain field distribution inside the fixating substrate was measured at three different levels of the dental implant, when it was loaded alone and in the case when there were loaded two dental implants simultaneously.Conclusions: The most stresses are concentrated in the neck-area of the dental implant. If there are loaded two or more dental implants simultaneously, the distance between them influences strain distribution. The measurements were conducted in vitro and do not represent the in vivo conditions, but serve further important facts regarding biomechanical properties of dental implants.
