The lack of compatible prosthetic components can be a complication during oral rehabilitation using outdated implants.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.

The high survival rate of osseointegrated dental implants is well documented, but it is becoming increasingly clear that successfully integrated implants are susceptible to disease conditions that may lead to loss of the implant. Although placement and restoration usually are included in the domain of the periodontal, oral and maxillofacial surgery, or prosthetic specialist, given the increasing numbers of patients treated with osseointegrated fixtures, it is increasingly likely that maintenance of these implants by the general dentist will become much more common. However, the surrounding tissues may be subject to inflammatory conditions similar to periodontal disease and so require maintenance. This article discusses the background, cause, and diagnosis of peri-implant disease, as well as the maintenance, care, and treatment of peri-implant infection in osseointegrated implants.

ABSTRACT Aim The present review aims to discuss the last 10 years published data on the topic of the use of osseointegrated implants in diabetic subjects, particularly regarding the influence of antibiotics administration in the perioperative period. Background In the last decades, oral rehabilitation significantly has evolved particularly with the use of osseointegrated implants. Increased life expectation of population is reflecting in a greater number of diabetic patients who might require dental osseointegrated implants rehabilitation. Diabetes was considered for a long time as a contraindication for oral implant placement. In this context, the use of antibiotics is still a controversial factor when we correlate it to implant success rate. Review results Although 228 articles were initially selected for evaluation of proposed criteria, only 16 articles were considered valid. Among the 16 selected articles, only six articles represented clinical research that discussed the influence of the antibiotic in the success of osseointegration of dental implants in diabetic subjects. Five were retrospective studies and one a prospective research. Conclusion Data favors the use of antibiotics without significant side effects but clinical investigations of the need of prophylaxis antibiotic or therapeutic antibiotics are still scarce. The lack of adequate methodology is one of the main problems of the current articles. It is important to emphasize that studies should present detailed methodology in order to allow reproducibility. Clinical significance Permanent tooth loss is a pathological condition that affects millions of people worldwide. The possibility of successful treatment of edentulous areas through osseointegrated implants in those systemic compromised patients is a matter of scientific discussion. Although antimicrobial agents must be used rationally and carefully to avoid development of bacterial resistance, more studies are needed in order to support evidence regarding the influence of antibiotics in the success of dental implant surgery in diabetic patients.

One of the most important concerns during posterior mandibular implant placement is avoiding the mandibular canal. Nerve injury can be very disturbing to the patient, possibly causing mild paresthesia to complete anesthesia. Explantation of a dental implant that gas violated the mandibular canal is the most recommended treatment. However, an osseointegrated implant that placed in the mandibular canal can be left if the patient shows no symptoms. In this case report, we describe a technique to maintain the apexes of the implants while partially removing fractured osseointegrated implants previously placed in the mandibular canal.

SummaryIntroduction. Dental implant therapy has become a popular method of replacing one or more missing teeth. Osseointegrated dental implants have been studied from histological, microbiologic and biomechanical point of view, but the neurophysiologic integration of the implants and the supported prostheses has received less attention. The sensory mechanism of dental implants is qualitatively different from that of natural teeth. Psychophysiological tests are used to determine the tactile sensibility perceived with the implants and teeth.Aim of the study. The purpose of this study was to compare tactile sensibility of natural teeth and osseointegrated dental implants.Material and methods. Forty-three patients were included in the study. Natural teeth were divided into two groups: non endodontically treated teeth (NETT) and endodontically treated teeth (ETT). Load tests were done by a computer-controlled pressure sensitive device („Power Lab“ Data Acquisition System - model 4/25T, sensor - model MLT003/D; ADInstruments), specially modified for intraoral use. Pushing forces were applied parallel to the vertical axis of teeth and implants. The patient held a signal button which he/she activated as soon as touch was sensed. At this moment the computer registered passive absolute tactile threshold - measured in Newtons. The mean values of passive absolute tactile threshold for natural teeth and dental implants were calculated. Comparison of the mean values was performed by the means of t-test.Results. Passive absolute tactile threshold for osseointegrated dental implants was 2.39 N (SD=1.92), and for teeth - 0.67 N (SD=0.72), for non endodontically treated teeth it was 0.63 N (SD=0.72) and for endodontically treated teeth - 0.73 N (SD=0.69). The differences in mean values were statistically significant (p<0,0001) except for mean values of NETT vs. ETT.Conclusion. This study shows that patients with osseointegrated implants subjectively feel “touch” sensation when greater force is applied compared with natural teeth.

There are many studies suggest that a peripheral feedback pathway can be restored with osseointegrated implants even after tooth loss. This implant mediated sensory-motor control, known as osseoperception may have important clinical implications in improving masticatory function with implant supported prosthesis. To understand this psychophysical integration of implants, available literature was evaluated using various online resources such as Pubmed, Google scholar, etc. using keywords like “osseoperception”, tactile sensibility, implant mediated sensory-motor control and mechanoreceptors. The long-term integration of an implant-bone restoration depends in part on optimal load distribution on the bearing tissue. Because natural teeth and implants vary in their anchorage mechanisms so there is a fundamental difference in the perception and control of the loading. The current review of literature deals with these issues and has been summarized under following heads: • Mechanism of osseoperception • Neurophysiological and psychophysical methods of assessing phenomenon of osseoperception • Mechanoreceptors contributing to osseoperception • Different concepts of osseoperception Keywords: Osseointegration, osseoperception, active threshold, passive threshold, dental implant

A basic tenant of successful osseointegration is that the implant resides in a sufficient quality and quantity of bone to ensure bone contact and thus stabilization. A prospective, randomized controlled preclinical trial was conducted to evaluate the bone-to-implant contact (BIC) when placing implants in bone regenerated by 3 different combinations of biphasic calcium phosphate (BCP). Dental implants were placed into the regenerated ridges of 6 female foxhounds; the ridges were reconstructed with different formulations of BCP in combination with an hydroxyapatite collagen membrane. They were retrieved after 3 months to perform light microscopic and histomorphometric analyses. Implants in each group appeared to be stable and osseointegrated. Light microscopic evaluation revealed tight contacts between the implant threads with the surrounding bone for all 4 groups. The mean BIC ranged from 64.7% to 73.7%. This preclinical trial provided clinical and histologic evidence to support the efficacy of all 3 formulations of BCP to treat large alveolar ridge defects to receive osseointegrated dental implants.

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.

Edentulism is usually associated with the aging patient. However, total or partial tooth loss also affects young individuals, mainly as a result of trauma, decay, anodontia, or congenital and acquired jaw defects involving the alveolar processes. For elderly patients, the use of oral implants has become an accepted treatment modality for edentulism, and most of today's knowledge regarding implants is based on such practice. There has been hesitation to perform implant therapy for growing children; hence, few children to date have been provided with implant-supported construction. Consequently, little is known about the outcome of the osseointegration procedure in young patients, and until now, only a limited number of case presentations have been reported. This article reviews the current literature to discuss the use of dental implants in growing patients and the influence of maxillary and mandibular skeletal and dental growth on the stability of those implants. The literature review was performed through Science Direct, Wileys Blackwell Synergy, PubMed, Google, Embase, Medknow publications, and Springer for references published from 1963 to 2011. It is recommended to wait for the completion of dental and skeletal growth, except for severe cases of ectodermal dysplasia.

The loss of alveolar bone volume is a physiological consequence of tooth loss, which if not done carefully preserved and becomes a significant functional and aesthetic risk for the installation of osseointegrated dental implants. The dimensional differences of the alveolar ridge can be attenuated with different graft materials and surgical procedures. The presentation of this case illustrates one of the various surgical techniques to reduce bone resorption and maintain the volume of tissue to be rehabilitated in a more predictable manner and reducing problems in the future, thus increasing the chances of successful rehabilitation osseointegrated dental implant.

The most common bone disorder found by implant dentists is osteoporosis, which is a systemic skeletal disorder associated with aging, which is characterized by loss of bone mass, making bones fragile and more susceptible to fractures. The World Health Organisation has defined osteoporosis as a bone mineral density level greater than 2.5 standard deviations below the mean of young normal women. After 60 years of age, a third of the population have this disorder, it occurs twice as often in women than in men. It is estimated that 1.3 million fractures and 133,000 all hip fractures occur every year as a result of osteoporosis. This study aimed to discuss aspects of the pharmacological action of Bisphosphonates (BP) and their influence on the bone tissue when associated with treatment with dental implants. There are several types of treatments that prevent or prevent the progression of osteoporosis. So, BP, such as alendronate, are inhibitors of bone resorption. Act as controlling the development of osteoporosis by increasing the process of bone density and decrease its reabsorption, often acting as supporting the process of osseointegration of dental implants.

Abstract The relationship between bisphosphonates (BP) and dental implant failure has not been fully elucidated. The purpose of this retrospective radiographic study was to examine whether patients who take BP are at greater risk of implant failure than patients not using those agents. Treatment records of 362 consecutively treated patients receiving endosseous dental implants were reviewed. The patient population consisted of 227 women and 135 men with a mean age of 56 years (range: 17–87 years), treated in the University at Buffalo Postgraduate Clinic from 1997–2008. Demographic information collected included age, gender, smoking status, as well as systemic conditions and medication use. Implant characteristics reviewed included system, date of placement, date of follow-up radiographs, surgical complications, number of exposed threads, and implant failure. The relationship between BP and implant failure was analyzed using generalized estimating equation (GEE) analysis. Twenty-six patients using BP received a total of 51 dental implants. Three implants failed, yielding success rates of 94.11% and 88.46% for the implant-based and subject-based analyses, respectively. Using the GEE statistical method we found a statistically significant (P = .001; OR = 3.25) association between the use of BP and implant thread exposure. None of the other variables studied were statistically associated with implant failure or thread exposure. In conclusion, patients taking BP may be at higher risk for implant thread exposure.

Radiotherapy is used to treat patients with head and neck cancers as a primary therapy or as an adjuvant to surgery or chemotherapy. Irradiation results in several complications that can be very overwhelming to the patient. Frequently there is loss of function due to tooth loss, compromised aesthetics, pain and discomfort from xerostomia and mucositis, it also significantly impacts the quality of life.
A major advance in dentistry is the successful rehabilitation and replacement of lost teeth by osseointegrated implants. However, the risk of osteoradionecrosis and failure of osseointegration are barriers to implant therapy for those irradiated patients.
The aim of this review article is to primarily find out whether the radiotherapy used in the treatment of head and neck cancer patients can affect the success and survival of dental implants according to different studies, and also, to highlight some other pertinent factors that may concurrently influence these implantation.
The primary outcome measure shows implants survival in irradiated patients. Most of the studies reported that dental implants can osseointegrate and remain functionally stable in irradiated patients following oral cancer surgery. Accordingly, rehabilitation using dental implants is a viable option for head and neck cancer patients receiving radiotherapy. However, all studies included indicated that survival was significantly higher in non-irradiated patients.
Factors such as the mode of radiation therapy delivery, gender, age, implant site and radiation dose at the implant site can affect the survival of dental implant.
More research and randomized controlled trails are needed for more accurate judgment.

Abstract Despite its high success rate, therapy with osseointegrated dental implants is not free of complications. Among the problems that may occur is fracture of implants, which, albeit a rare phenomenon, may lead to unpleasant clinical outcomes for the patient, as well as for the clinician. Thus, it is paramount to know the factors related to the biological processes involved in maintenance of osseointegration and biomechanics applied to dental implants to prevent such complications, as well as treatment options available to deal with the problem. Therefore, the objectives of this work were to investigate the literature to identify causative factors that may lead to fracture of dental implants and to discuss available procedures.

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.

Introduction: Osseointegrated dental implants have been routinely used in oral rehabilitation. Patients with dysplastic bone diseases represent a particular challenge for oral rehabilitation with dental implants. Nevertheless, the installation of implants in patients with cemento-osseous dysplasia (COD) has been reported with apparent success. Objective: In this paper, we present a case of a patient with COD in which a dental implant had been installed and lost six months later. In this regard, we analyzed pertinent aspects of the indications for dental implants in patients with COD considering the pathogenesis, dysplastic nature, and behavior of the disease. Conclusion: The present case report illustrates that COD can be considered a limiting factor in the recommendation for a dental implant. Because of this, it is imperative to inform the patient about the risks of surgically manipulating the diseased bone.

Selective serotonin reuptake inhibitors (SSRIs), the most widely used drugs for the treatment of depression, have been reported to reduce bone formation and increase the risk of bone fracture. Since osseointegration is influenced by bone metabolism, this study aimed to investigate the association between SSRIs and the risk of failures in osseointegrated implants. This retrospective cohort study was conducted on patients treated with dental implants from January 2007 to January 2013. A total of 916 dental implants in 490 patients (94 implants on 51 patients using SSRIs) were used to estimate the risk of failure associated with the use of SSRIs. Data analysis involved Cox proportional hazards, generalized estimating equation models, multilevel mixed effects parametric survival analysis, and Kaplan-Meier analysis. After 3 to 67 mo of follow-up, 38 dental implants failed and 784 succeeded in the nonusers group, while 10 failed and 84 succeeded in the SSRI-users group. The main limitation of this retrospective study was that drug compliance dose and treatment period could not be acquired from the files of the patients. The primary outcome was that compared with nonusers of SSRIs, SSRI usage was associated with an increased risk of dental implants failure (hazard ratio, 6.28; 95% confidence interval, 1.25-31.61; p = .03). The failure rates were 4.6% for SSRI nonusers and 10.6% for SSRI users. The secondary outcomes were that small implant diameters (≤4 mm; p = .02) and smoking habits ( p = .01) also seemed to be associated with higher risk of implant failure. Our findings indicate that treatment with SSRIs is associated with an increased failure risk of osseointegrated implants, which might suggest a careful surgical treatment planning for SSRI users.

There are a lot of dental implants kit designs [1, 2, 3]. All of them are based on a pin or a screw either cemented or osseointegrated into the human jaw. This paper makes a study on the shape the pin or screw dental implant should have. Presented theoretical research was performed using DEFORM 2DTM software simulations, [4]. There were studied several shapes of the dental implant, both for pins and screws. The studied shapes were, basically: cylindrical, conical, ogival and pointed. The criterion for analysis was the effective stress into the jaw bone during the insertion. As a conclusion, the optimal shape of the dental implant depends on the real case, being a customized shape depending on the current conditions of insertion.

The introduction of osseointegrated implants have revolutionized the art and science of modern dentistry giving a new lease of life to the restorative aspects in day-to-day practice. Immediate loading (IL) of dental implants can significantly decrease treatment time and thus increase patient acceptance. IL of dental implants has recently gained popularity due to several factors including reduced trauma as well as aesthetic and psychological benefits to the patient. The present case report describes the immediate replacement of partially edentulous maxilla using Nobel Active™ implant. It describes about the diagnosis, treatment planning and procedures involving the placement of single tooth immediate implant followed by uneventful healing.

Titanium is a primary metallic biomaterial widely used in dental implants because of its favorable mechanical properties and osseointegration capability. Currently, increasing interests have been taken in the interaction between titanium implant surface and surrounding bone tissue, particularly in surface topographical aspect. There are currently several techniques developed to modify surface topographies in the world market of dental implant. In this review, state of titanium implant surfaces in topographical aspect is presented from relatively smooth surfaces to rougher ones with microtopographies and/or nanotopographies. Each surface is summarized with basic elaborations, preparation methods, mechanisms for cellular responses and current availabilities. It has been demonstrated that rough surfaces evolving from micro- to nano-scale, especially hierarchical micro-and nanotopographies, are favorable for faster and stronger osseointegration. Further experimental and clinical investigations will aid in the optimization of surface topography and clinical selection of suitable implants.

Management of one or more failing distal implants in an implant supported fixed prosthesis in a completely edentulous maxilla creates a challenging situation. Restoring immediate function with additional implants in such a situation can be a challenge considering the loss of supporting bone, need for grafting, age, and the patient's desire for immediate fixed dental prosthesis. This clinical report describes a situation where a zygomatic implant has been placed unilaterally and splinted with osseointegrated conventional implants by an immediate fixed provisional restoration.

Permucosal osseointegrated dental implants are a highly effective and predictable treatment modality for edentulism. This review discusses some controversial aspects of the definitions for success and failure of root-form dental implants. The discussion will focus on the underlying pathologies that, if untreated, may lead to loss of the implanted device. Few clinical syndromes are described based on human pathological material and clinical presentation. The theoretical chronological relationship between implant loss and the incidence of pathology of the soft- and hard-tissue seal around implants is also discussed. The review also examines the finding that implant failures are not randomly distributed in the treated populations and that implant loss clusters in specific high-risk groups and individuals. Known risk indicators, and possible risk factors, are discussed, taking into account the patient, the reconstruction, the implant, and implant site-specific factors. Particular emphasis is placed on the need for better determination of whether periodontal patients are at higher risk for implant failures as a consequence of their increased susceptibility to infectious, inflammatory-response-driven tissue breakdown.

Osseointegration is the basis of successful dental implantology and the foundation of cementless arthroplasty and the osseointegrated percutaneous prosthetic system. Osseointegration has been considered irreversible thus far. However, controlled heating or cooling of dental implants could selectively damage the bone at the bone–implant interface, causing the reversal of osseointegration or “osseodisintegration”. This review compares five methods for implant removal, published as patent documents between 2010 and 2018, which have not yet been discussed in the scientific literature. We describe these methods and evaluate their potential for reversing osseointegration. The five methods have several technical and methodological similarities: all methods include a handpiece, a connecting device for coronal access, and a controlling device, as well as the application of mechanical and/or thermal energy. The proposed method of quantifying the temperature with a sensor as the sole means for regulating the process seems inadequate. A database used in one of the methods, however, allows a more precise correlation between a selected implant and the energy needed for its removal, thus avoiding unnecessary trauma to the patient. A flapless, microinvasive, and bone-conserving approach for removing failed dental implants, facilitating successful reimplantation, would benefit dental implantology. These methods could be adapted to cementless medical implants and osseointegrated percutaneous prosthetics. However, for some of the methods discussed herein, further research may be necessary.

Abstract The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant fracture is one possible complication that results in ultimate failure of the dental implant. Such a complication poses a management crisis even for the most experienced clinician. This article reports on a case of implant fracture, its possible causes, and how the case was managed.

Polymorphisms in matrix metalloproteinases (MMPs) genes have been associated with several pathologies, including dental implant loss. MMP-3 is crucial to the connective tissue remodeling process. The objective of this study was to investigate the possible relationship between -1612 MMP-3 polymorphism and the early implant failure. A sample of 240 non-smokers was divided: test group 120 patients with one or more early failed implants and control group 120 patients with one or more healthy implants. Genomic DNA from oral mucosa was analyzed by PCR-RFLP. No association of early implant loss with genotypes and alleles of the -1612 polymorphism in MMP-3 were found by the Chi-squared test. Only the presence of the -1612 polymorphism of MMP-3 is not a genetic risk factor for early loss of implants.

Abstract The purpose of this study was to design an instrument for the optimal guiding of osseointegrated implants intraoperatively to achieve parallelism or desired angulations. Seven patients (4 males and 3 females) were enrolled in the investigation. They ranged in age from 44 to 61 years. Using an instrument designed by the senior author that permitted optimal guiding of the osteotomy instruments (33 Osteofix Oy, Oulu, Finland) we placed in these patients, root form, single stage implants. The difference in angulations between the first and the remaining implants was measured using the abutment replicas on the working models. It was found that the mean deviation angle between the first and the adjacent implant replicas was 2.2° (SD = 0.4°). The largest deviation angles were 2.3° (SD = 0.5°) and 3.1° (SD = 0.8°). The study indicated that the instrument had been designed in a functional manner and that all implants in such relationships can be inserted into their desired positions, either parallel to one another or with the desired angle for the planned prostheses.

Micromotion of dental implants may interfere with the process of osseointegration. Using three different types of virtual biomechanical models, varying contact types between implant and bone were simulated, and implant deformation, bone deformation, and stress at the implant-bone interface were recorded under an axial load of 200 N, which reflects a common biting force. Without friction between implant and bone, a symmetric loading situation of the bone with maximum loading and displacement at the apex of the implant was recorded. The addition of threads led to a decrease in loading and displacement at the apical part, but loading and displacement were also observed at the vertical walls of the implants. Introducing friction between implant and bone decreased global displacement. In a force fit situation, load transfer predominantly occurred in the cervical area of the implant. For freshly inserted implants, micromotion was constant along the vertical walls of the implant, whereas, for osseointegrated implants, the distribution of micromotion depended on the location. In the cervical aspect some minor micromotion in the range of 0.75 μm could be found, while at the most apical part almost no relative displacement between implant and bone occurred.

The goal of mandibular reconstruction is to rehabilitate the patient by restoring occlusal relationships, lower facial contour, oral continence, and a denture-bearing surface. One of the major advantages of the use of vascularized bone over all other methods of mandibular reconstruction is its ability to achieve dental rehabilitation rapidly. The use of osseointegrated dental implants is a valuable adjunct in oral rehabilitation. It provides the most rigid form of stabilization to withstand the forces of mastication. In situations In which soft tissue reconstruction or the height of the alveolar ridge is not sufficient for a tissue-borne denture, implants offer the most suitable alternative. Mandibular reconstruction with free tissue transfer techniques is Ideally suited for the placement of implants. These can be inserted at the time of mandibular reconstruction. Four months after surgery, when the integration process has occurred, the implants are unroofed, loaded, and ready for prosthetic placement. We will present several representative patients who underwent mandibular reconstruction with microvascular free bone transfer who have been successfully rehabilitated by osseointegrated implants. The process of osseointegration, different types of dental implants, and issues regarding radiation and Implants are discussed. This is the first report of dental rehabilitation by primary placement of dental implants in patients undergoing microvascular mandibular reconstruction.

Abstract Osseointegrated dental implants are inserted into the alveolar ridge, and for them to function as tooth replacements, the surrounding tissues need to adapt to them. Just as with teeth, dental implants traverse the oral mucosa and have access to the contaminated environment of the oral cavity. Therefore, periodontal and peri-implant tissues are important for establishing a protective barrier. The aim of the present study was to perform a histologic analysis of the mucosa surrounding osseointegrated implant cover screws. For this study, 17 mucosal specimens were obtained from 12 patients during the second surgical session for implant exposure to the oral environment. After histologic preparation, specimens were sectioned perpendicularly to the mucosal surface to a thickness of about 3 µm, stained with 1% toluidine blue, and examined under light microscopy. All specimens showed a keratinized, stratified, squamous epithelium with well-defined strata. In the lamina propria, unorganized dense connective tissue was noted in the reticular layer, and in 4 samples, a chronic inflammatory infiltrate was seen in this region. The papillary layer presented tall connective papillae consisting of loose connective tissue. The results of this study confirm the hypothesis that the mucosa that conceals osseointegrated implant cover screws has the same morphologic characteristics as the alveolar masticatory mucosa. Furthermore, clinical conditions of normality in peri-implant tissues may not coincide with situations of histologic normality.

In the manufacturing of osseointegrated dental implants there is no technical standard that defines the body shape and the threads fillets profiles (spirals). Dental implant manufacturers develop implant shapes to increase the implant-bone contact surface area, to improve primary stability, and to promote better distribution of oral forces to bone. The aim of this study was to characterize the dental implant of thread fillets profiles made in Brazil and to analyze the influence on primary stability and force distribution on the implant-bone interface. Seven groups of dental implants with cylindrical (Master Screw®), conical (Flash®, Master Grip®, and Conect Conic®), and hybrid (Easy Grip®, AR-Torq®, and AR Morse®) body shapes were inserted in polyethylene, polyurethane, and in swine bone. The results showed that tapered implants present greater primary stability, the threads profiles must be rounded, the square thread induces highest compressive stresses in the bone, and the microthreads in the cervical reduce the concentration of stresses.

Abstract Dental implant treatment is successful; however, an implant can become infected during or after osseointegration. The two case reports presented here demonstrate, anecdotally, the effectiveness of endodontic calcium hydroxide paste for the surface treatment of infected, healing, or osseointegrated dental implants. Calcium hydroxide may be an appropriate surface detoxifying agent for local dental implant infections. A sequence of calcium hydroxide and 0.2% chlorhexidine gluconate surface treatment may provide a broad range of antimicrobial action for detoxifying recalcitrant infections. Calcium hydroxide should not be left in the surgical site.

Abstract Dental implants have enabled a dramatic increase in the quality of life for many partially edentulous and edentulous patents. Immediate loading of newly placed dental implants is a recent advancement that attempts to meet patient demand. However, immediate loading of a just placed implant may induce implant failure to osseointegrate. Some patients can generate a biting force that can reach approximately 1300 Newtons (N) in the posterior jaws. The magnitude of bite force that would cause failure of osseointegration of newly placed implants is currently unknown. It has been proposed that osseointegration would fail if an implant is luxated in bone more than 50 to 150 microns. Fibrous tissue, not bone, would form. This study investigated the quantity of various off-axial forces required to move a nonosseointegrated 4.3 × 13 mm implant 50 microns. The previously published pilot study for this study found that the amount of horizontal force required to displace an implant 50 microns was approximately 150 N. This study found that the force needed to move the implants 100 microns at a horizontal approach, 0 degrees, averaged 50 N, with a range of 23–79 N; at 22 degrees, averaged 52 N, with a range of 27–70 N; and at 60 degrees averaged 87 N, with a range of 33–105 N.

Dental implant treatment is an important therapeutic modality with documented long-term success for replacement of missing teeth. However, dental implants can be susceptible to disease conditions or healing complications that may lead to implant loss. This case-control study identified several risk indicators associated with failure such as smoking and alcohol consumption. The use of postoperative antibiotics or wide-diameter implants may significantly reduce implant failure. Knowledge of patient-related risk factors may assist the clinician in proper case selection and treatment planning.

The biologic process of osseointegration (bone to implant interface), in which the implant forms an intimate relationship with the bone, provides the foundation for modern dental implants. Osseointegration necessitates a varying length of healing time. Despite the high success and survival rates of dental implants, problems do occur, necessitating ongoing periodontal and prosthodontic care. This failure frequently results in "peri-implantitis," which affects the soft and hard tissues surrounding the osseointegrated implants, resulting in the formation of a peri implant pocket and bone loss. Decontamination is a difficult feature of surgical regenerative therapy for peri-implantitis that has an impact on its success. Because microbial biofilms play such a significant part in the aetiology of peri-implant illnesses, it has long been assumed that eliminating microbial pathogens would be beneficial.

Dental implant practice has now become a major choice for replacement of missing teeth in modern dentistry. Over the years, the success rate of dental implants has increased from 80-90% to 96-98%. However, due to lack of proper availability of soft tissue and hard tissue along with improper alignment of dental implants often pose aesthetic concerns in anterior aesthetic zone though the implant is fully osseointegrated with no signs of clinical mobility. This case report presents a case of a 21 years old male with a history of tooth loss due to trauma 8 months back and rehabilitation with dental implant 6 months back. On examination, mid-labial recession of around 3mm associated with #11 with no clinical signs of overlying inflammation was noted. Intact bone support was revealed by IOPAR. The recessed area around dental implant was managed with connective tissue graft and coronally advanced flap.

ABSTRACT The use of dental implants has revolutionized the treatment of partially and fully edentulous patients today. While in many cases dental implants have been reported to achieve long-term success, these are also not immune from the complicationsincludingperi-implant mucositis and peri-implantitis. Peri-implantitis is an inflammatory process which involves bone loss around osseointegrated implant in function. The etiology of the disease has been attributed to bacterial infections, occlusal overload, surgical trauma, faulty or incorrect prosthetic design and/ or improper implant placement. Diagnosis is based on changes in colour of the gingiva, bleeding and probing depth of peri-implant pockets, suppuration, x-ray and gradual loss of bone height around the tooth. Treatment modalities will differ depending upon whether it is a case of periimplantmucositis or periimplantitis, Therapeutic objectives focus on control of infection, detoxification of the implant surface and regeneration of the alveolar bone. This review article gives a brief description of etiopathogenesis, diagnosis and various treatment options in the management of periimplant disease.

This study aimed to investigate the influence of implant design (in terms of diameter, length, and thread shape), in-bone positioning depth, and bone posthealing crestal morphology on load transfer mechanisms of osseointegrated dental implants based on platform-switching concept. In order to perform an effective multiparametric comparative analysis, 11 implants different in dimensions and in thread features were analyzed by a linearly elastic 3-dimensional finite element approach, under a static load. Implant models were integrated with the detailed model of a maxillary premolar bone segment. Different implant in-bone positioning levels were modeled, considering also different posthealing crestal bone morphologies. Bone overloading risk was quantified by introducing proper local stress measures, highlighting that implant diameter is a more effective design parameter than the implant length, as well as that thread shape and thread details can significantly affect stresses at peri-implant bone, especially for short implants. Numerical simulations revealed that the optimal in-bone positioning depth results from the balance of 2 counteracting effects: cratering phenomena and bone apposition induced by platform-switching configuration. Proposed results contribute to identify the mutual influence of a number of factors affecting the bone-implant loading transfer mechanisms, furnishing useful insights and indications for choosing and/or designing threaded osseointegrated implants.

In the following case report, three osseointegrated implants placed in a dysfunctional and nonaesthetic position were successfully relocated with innovative surgical techniques were followed by a comprehensive dental rehabilitation. The goal of this report is to communicate the surgical techniques used to successfully relocate dental implants rather than replace them. Two techniques were used for these implants relocation. One technique consisted of displacing the integrated implant with some similarity to the alveolar distraction osteogenesis but without using the distraction device. The second surgical technique involved the displacement of the 2 adjacent implants, similarly to the first approach, except that an osseoinductive molecule, recombinant human bone morphogenetic protein-2, was used for guided bone growth. It was possible to relocate dental implants within bone blocs and rehabilitate them to adopt new dental abilities by complying with bone regeneration parameters. However, advanced treatment planning with computerized tomography scans, parametric software, and stereolithography models as well as guided surgery and bone regeneration products were used.

With the increased use of osseointegrated implants and with many implants functioning for long periods of time, the soft tissue barrier around implants has become more important. This paper reviews the soft tissue response around implants under healthy and diseased conditions and presents the etiology of peri-implant tissue breakdown. Diagnostic techniques such as probing pocket depth, radiographic evidence, and microbial sampling have been analyzed and modified from the periodontal field and used during the maintenance phase of the dental implant. The long-term goal of implant maintenance is to prevent or to arrest the progression of disease, and to achieve a maintainable implant site. Recent reports indicate that peri-implant tissues can be treated with either non-surgical or surgical techniques.

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.

Abstract Purpose Except for the occasional case report, there are no studies evaluating the success rate of osseointegrated dental implants in individuals infected with the human immunodeficiency virus (HIV). This study investigated the short-term clinical outcome of implant placement in a group of HIV-positive and HIV-negative individuals who required complete dentures. Methods and Materials Edentulous subjects were recruited from an HIV-dedicated clinic and a dental school clinic. Two BioHorizons® dental implants were placed in the anterior mandible to support an overdenture opposing a maxillary denture. Outcome measurements obtained six months after activation of implants were presence of pain, mobility, soft tissue status, and radiographic bone level. Descriptive statistics were used. Results Twenty-nine edentulous adults, including 20 HIV-positive subjects (test) and nine HIV-negative subjects (control), participated. The test group had six females, 14 males; 13 Whites, four African-Americans, and three Hispanics with a mean age of 48.9 years (range: 35-59). The mean CD4 count was 467 cells/mm3 (range: 132-948). The control group had six females, three males; seven Whites, and two Hispanics with a mean age of 65.3 years (range: 50-82). Short-term success rate was 100% for both groups. No difference in clinical outcome was found between the groups. Conclusion This study demonstrated dental implants are well tolerated and have predictable outcomes for HIV-infected individuals for the duration of the study and probably over an even longer term.

SummaryBackground: Connecting an osseointegrated implant and a natural tooth is a treatment alternative for partially edentulous patients in some clinical situations. The main issue of a connected tooth-implant system is derived from the dissimilar mobility patterns of the osseointegrated fixtures and natural abutments causing potential biomechanical problems within the entire system. Purpose: The aim of this review was to multilaterally analyze and discuss the main biomechanical factors that may question the reliability of splinted tooth-implant system and the long-term success of fixed partial prostheses (FPPs) supported by both teeth and implants with an emphasis on the disparity of mobility of these two different abutments.Material and methods: An electronic MEDLINE (PubMed) search supplemented by manual searching was performed to retrieve relevant articles. An assessment of the identified studies was performed, the most valuable articles were selected and biomechanical outcomes of tooth-implant splinting system were analyzed.Results: 3D FEM stress analyses and photoelastic studies show uneven load distribution between the tooth and the implant and stress concentration in the crestal bone around the implant neck when connected to a natural tooth by FPPs. However, clinical studies demonstrate good results for both the implants and FPPs supported by splinted implant-to-tooth abutments.Conclusion: Connecting implants to natural teeth is not a preferable treatment option because of possible inherent biomechanical complications.

AbstractThe placement of dental implants in the maxillary anterior region is a challenge for clinicians because of existing anatomy and high esthetic demands. This article presents a case with limited anatomical three-dimensional space for implant placement and immediate loading for esthetic and functional restoration.Virtual implant placement was planned using cone beam computed tomography (CBCT) scan, casts with trial denture bases, implant planning software (Nobel Clinician), and prosthetic designing software (Procera) to fabricate a surgical guide.The article describes the successful application of “Smart Fusion” (Nobel Biocare) in the production of the surgical template for accurate placement of osseointegrated implants.
