Abstract:
The process of osseointegration around dental implants is similar to the biological events occurring during bone repair and fracture healing. Therefore, bone metabolic activity plays a crucial role on the success of osseointegration, and dysregulation of bone metabolism can have a negative impact on bone healing and implant osseointegration. Accordingly, it could be hypothesized that drugs interfering with healing and bone metabolism could affect osseointegration and implant survival. Looking into the relationship between pharmacology, osseointegration, and dental implants, drugs can open the door for new pharmacological innovations to improve implant success and avoid unnecessary complications, and it is also of special interest because most implant patients are elder adults who are often polymedicated. In this commentary, we discuss the discoveries made by us as well as by other researchers regarding the effect of several drugs on bone, osseointegration, and implant survival. Of particular interest is the growing evidence showing that commonly used drugs such as nonsteroidal anti-inflammatories, serotonin reuptake inhibitors, and proton pump inhibitors could lead to implant failure.

Abstract:
With the development of nanotechnology, many researches have shown that nanometer-scaled materials especially TiO2nanotube have a positive effect on cellular behavior and surface characteristics of implant, which are considered to be crucial factors in osseointegration. However, it has not yet been verified which nanotube size is effective in osseointegrationin vivo. The aim of this study was to evaluate the effect of implant surface-treated with different size of TiO2nanotubes on osseointegration in rat femur. The customized implants (threaded and nonthreaded type), surface-treated with different diameter of TiO2nanotubes (30 nm, 50 nm, 70 nm, and 100 nm nanotube), were placed on both sides of the femur of 50 male Sprague-Dawley rats (6 weeks old). Rats were sacrificed at 2 and 6 weeks following surgery; then the specimens were collected by perfusion fixation and the osseointegration of implants was evaluated by radiographic and histologic analyses and removal torque value test. The mean of bone area (%) and the mean of removal torque were different in each group, indicating that the difference in TiO2nanotube size may influence new bone formation and osseointegration in rats.

Abstract:
The objectives of this study were to evaluate osseointegration of dental implant in the jaw bone in the young and elderly population and comparing the results to assess indicators and risk factors as age for the success or failure of dental implants. A retrospective study of 107 implants (Impladent, LASAK, Czech Republic) was prepared. The patients at implants surgery were divided in three groups. The patients were followed-up for a 7-year period. We evaluated osseointegration from long term point of view as a change of marginal bone levels close to dental implant. Marginal bone levels were recorded and analysed with regard to different patient- and implant-related factors. An influence of chronological age on change of marginal bone levels during 6-year retrospective study vas evaluated. The study examined 47 patient charts and 107 implants from the Second Faculty of Medicine, Charles University and University Hospital Motol. We proved that young healthy patients with long bridges or Branemarks have the same progression of marginal bone levels changes. The chronological age hasn’t therefore direct influence on the osseointegration from long term point of view. But we found that the length of dental suprastrucure-prosthetic construction negatively influences marginal bone changes, though these results weren’t statistically significant. More extensive dental implant suprastrucure undergoes smaller osseointegration. On the other hand the length of dental suprastrucure (prosthetic construction) negatively influences dental osseointegration in both groups of patient.

Abstract:
The stability of dental implants is a prerequisite for osseointegration. Osseointegration is the process that involves the formation of bone around the dental implant, resulting in increased stability and its integration in the organism. Therefore, successful osseointegration contributes to a functionally optimal treatment. There is a need for a clinical method capable of measurement of bone quality at the time and following implant placement, to measure the degree of osseointegration and the ability of the implants to distribute loads to the surrounding bone. Research to date focuses on finding an ideal method to assess the osseointegration of dental implants in order to improve and broaden the clinical indications of dental implant systems. This paper aims to supply information about current methods used to assess the osseointegration of dental implants. In this regard, a literature review was conducted. Full-text scientific articles relevant to the chosen topic, written in English or whose text could be accessed in English were included.

Abstract:
ABSTRACT Introduction Accurate assessment of osseointegration in dental implants requires precise radiographic visualization of pathologic conditions as well as anatomical structures. The present study aimed to evaluate the formation of bony tissue (osseointegration) using digital orthopantomogram (OPG) and cone beam computed tomography (CBCT) immediately after implant insertion (within 7 days) and 3 months postinsertion. Materials and methods Twenty single-implant sites on mandibular posterior regions were selected on patients irrespective of their gender. Both digital OPG and CBCT were done within a week and again after 3 months of implant insertion surgery, using the same exposure parameters. Results Three of the 20 implants were submerged and were excluded as the crestal bone height could not be measured. The participants were recalled for radiographic measurements after 3 months of implant placement. On an average, there was 0.03 mm of osseointegration at the apical portion after 3 months of implant insertion on digital OPG; 0.04 mm of osseointegration at the crestal bone height after 3 months on digital OPG; and 0.01 mm of osseointegration at the apical portion after 3 months on CBCT. No change or ≤0.02 mm of osseointegration at crestal bone height after 3 months on CBCT. Conclusion Both digital OPG and CBCT are significant for the assessment of osseointegration in implants, and hence, endow definite benefit for accurate assessment in terms of the success of the implant placement. Clinical significance However, CBCT is a better mode of evaluating dental implants but one should keep in mind that radiographic examination must be conducted to the benefit of the patient by application of the lowest achievable dose.

Abstract:
Dental implants are widely used in the field of oral restoration, but there are still problems leading to implant failures in clinical application, such as failed osseointegration, marginal bone resorption, and peri-implantitis, which restrict the success rate of dental implants and patient satisfaction. Poor osseointegration and bacterial infection are the most essential reasons resulting in implant failure. To improve the clinical outcomes of implants, many scholars devoted to modifying the surface of implants, especially to preparing different physical and chemical modifications to improve the osseointegration between alveolar bone and implant surface. Besides, the bioactive-coatings to promote the adhesion and colonization of ossteointegration-related proteins and cells also aim to improve the osseointegration. Meanwhile, improving the anti-bacterial performance of the implant surface can obstruct the adhesion and activity of bacteria, avoiding the occurrence of inflammation related to implants. Therefore, this review comprehensively investigates and summarizes the modifying or coating methods of implant surfaces, and analyzes the ossteointegration ability and anti-bacterial characteristics of emerging functional coatings in published references.

Abstract:
Dental implants are a widely used treatment modality for oral rehabilitation. Implant failures can be a result of many factors, with poor osseointegration being the main culprit. The present systematic review aimed to assess the effect of stem cells on the osseointegration of dental implants. An electronic search of the MEDLINE, LILACS, and EMBASE databases was conducted. We examined quantitative preclinical studies that reported on the effect of mesenchymal stem cells on bone healing after implant insertion. Eighteen studies that fulfilled the inclusion criteria were included. Various surface modification strategies, sites of placement, and cell origins were analyzed. The majority of the selected studies showed a high risk of bias, indicating that caution must be exercised in their interpretation. All the included studies reported that the stem cells used with graft material and scaffolds promoted osseointegration with higher levels of new bone formation. The mesenchymal cells attached to the implant surface facilitated the expression of bio-functionalized biomaterial surfaces, to boost bone formation and osseointegration at the bone–implant interfaces. There was a promotion of osteogenic differentiation of human mesenchymal cells and osseointegration of biomaterial implants, both in vitro and in vivo. These results highlight the significance of biomodified implant surfaces that can enhance osseointegration. These innovations can improve the stability and success rate of the implants used for oral rehabilitation.

Abstract:
The key factor in success of dental implants is its ability to integrate with the surrounding bone, or in short, osseointegration. The events leading tosuccess or failure of osseointegration of a dental implant takes place mostly at the tissue- implant surface. It would be no doubt to say, that the implant surface offers the greatest potential to alter the process of osseointegration.Although the main purpose of surface modification of implants is to achieve better osseointegration, a shortened period of healing is desirable for both the clinician and the patient.

Abstract:
The success of bone implants in the presence of osteoporosis is limited by lack of osseointegration between the implant and the natural bone. This study applied an electrochemical process to deposit simvastatin-nanohydroxyapatite (HA) coatings on porous implant surfaces and investigated the effects of these simvastatin-HA coatings on implant surfaces in an animal model of osteoporosis. In this study, simvastatin-HA coated implants were inserted into the tibia of osteoporotic rats. After 2, 4, and 12 weeks, tissue was retrieved for histomorphometric evaluation. The results indicated that the simvastatin-HA coatings increased bone-implant contact and new bone formation around implant surfaces. In conclusion, implants loaded with simvastatin by an electrochemical process improved implant osseointegration in osteoporotic rats. Furthermore, the increased concentration of simvastatin could affect the osseointegration, but the dose-effects also need further investigation.

Abstract:
The discovery of osseointegration of titanium implants revolutionized the dental prosthesis field. Traditionally, implants have a surface that is processed by additive or subtractive techniques, which have positive effects on the osseointegration process by altering the topography. In the last decade, innovative implant surfaces have been developed, on which biologically active molecules have been immobilized with the aim of increasing stimulation at the implant–biological tissue interface, thus favoring the quality of osseointegration. Among these molecules, some are normally present in the human body, and the techniques for the immobilization of these molecules on the implant surface have been called Biochemical Modification of Titanium Surfaces (BMTiS). Different techniques have been described in order to immobilize those biomolecules on titanium implant surfaces. The aim of the present paper is to present evidence, available from in vivo studies, about the effects of biochemical modification of titanium oral implants on osseointegration.

Abstract:
The use of exogenous materials to replace or repair dysfunctional tissues and organs has seen dramatic improvements since the time of the ‘physician-hero’. The past three decades have heralded the advancement of various materials and technologies for medical implant devices to repair, replace or regenerate irreversibly damaged tissues. Improvement in health outcomes, evident in life expectancy increase, has brought in its wake the increased need to replace or repair tissues, particularly weight-bearing bone tissues. Titanium (Ti), a non-magnetic, corrosion resistant, osseo-integrating metal, with a higher strength-to-weight ratio than the traditional stainless steel, has emerged as the material of choice for replacing bone and other support tissues. However, the quest for improved performance (osseointegration) and reduction in implant related infection resulting in the need for resection surgeries, has necessitated the need to improve the titanium-tissue interface mediated osseointegration process, and confer antimicrobial properties to the implant material surface. In this work, a simple cost effective physical and chemical modification strategies have been developed, to alter the surface chemistry, increase the surface water wettability and confer a nano topographic characteristic to the Ti surface. These surface parameters have been demonstrated to enhance the osseointegration process. The chemical treatments resulted in oxides containing the following ions: Calcium (Ca), for improvement of osteogenic cell adhesion to Ti surface, Silver (Ag), and Zinc (Zn) for conferring antimicrobial properties to the novel surface, and their composites (CaAg, CaZn and CaZnAg), Scanning electron microscope (SEM) profiles of the modified surface suggest that, ions are chemically bound and not physically deposited onto the Ti surface. Further evidence of this is provided by the release profile of these elements from the modified surface over a 28-day period. We have also demonstrated that, the physically modified Ti surface is better at incorporating our elements of interest than the commercially pure titanium (cpTi) surface. xi The results from a Staphylococcus aureus biofilm formation assay, and U2OS bone cell adhesion and proliferation studies, suggest that, the physical modifications enhanced both the antimicrobial performance and the osteoblast-like cell adhesion and proliferation. The suggestion also is that, the incorporated Ca further enhances the adhesion and proliferation of bone-like cells, whereas Zn and markedly Ag improve the modified Ti surface’s antimicrobial properties. However, Ag alone has been shown to have a toxic effect on the bone cells; a promising combination treatment involving Ca, Zn and Ag appears to have beneficial response in all tests.

Abstract:
Afirmação do problema. Estudos experimentais em animais são utilizados para avaliar previamente o resultado de pesquisas e sua necessidade de serem realizadas em humanos. Estudos em animais são fundamentais na implantodontia para que haja uma melhor compreensão da osseointegração. Durante o processo de execução de pesquisas nesse tipo de estudo, algumas dificuldades relacionadas ao manuseio, custos de manutenção e bem-estar dos animais tendem a dificultar o seu desenvolvimento. Finalidade. Esse estudo tem como objetivo, testar um novo dispositivo acoplado sobre o implante, para que possa atuar como uma extensão do mesmo, facilitando a realização da Análise de Frequência de Ressonância durante o processo de osseointegração permitindo que implantes instalados em ovelhas em diferentes períodos, possam ser reabertos sem que haja a necessidade de etapas cirúrgicas para a reabertura durante a realização de testes. Material e métodos. Foram utilizadas 4 ovelhas, sendo uma do Grupo Controle (GC) e 3 do Grupo Teste (GT). Cada animal recebeu oito implantes localizados próximos ao ângulo da mandíbula, sendo quatro do lado esquerdo e quatro do lado direito, totalizando, 32 implantes cone-morse Acqua® de 3,5 de diâmetro por 8,5mm de comprimento da empresa Neodent® que foram avaliados pela análise de frequência de ressonância com a medição do ISQ (Quociente de Estabilidade do Implante) utilizando um transdutor (SmartPeg) expressos numa escala de 0 a 100. Para o Grupo Controle (GC) as medições de ISQ foram realizadas pelo método convencional, onde o SmartPeg foi acoplado diretamente sobre a plataforma do implante. Já no Grupo Teste (GT) o dispositivo estudado, foi acoplado ao implante para que pudesse ser realizada a medição. Os períodos estudados foram: imediatamente após a cirurgia e com quatro semanas de osseointegração. Para a análise estatística foram empregados os testes de Wilcoxon e Man-Whitney com a probabilidade de 5% (p<0.05). Resultados. As médias obtidas no GC foram 50,47 imediatamente após cirurgia e 65,68 após 4 semana, enquanto que no GT foram 34,74 e 34,81, respectivamente. Comparando a diferença entre os grupos nas médias de ISQ imediatas e após quatro semanas, houve diferença significativa com p= 0.0321 e p= 0.0027, respectivamente, demonstrando que os resultados no GT nos dois períodos não foram equivalentes quando comparados ao GC. Conclusão. Os resultados demonstraram que o grupo teste, apesar de trazer benefícios em relação ao manuseio dos animais, não apresentou benefícios com relação à eficiência na leitura do ISQ, quando comparado ao método convencional.
Statement of the problem. Experimental studies in animals are used to pre-evaluate the results of research and their need to be performed in humans. Animal studies are fundamental in implantology so that there is a better understanding of osseointegration. During the execution of research in this type of study, some difficulties related to handling, maintenance costs and animal welfare tend to hinder its development. Purpose. This study aims to test a new device coupled on the implant, so that it can act as an extension of the same, facilitating the performance of the Resonance Frequency Analysis during the osseointegration process allowing implants installed in different periods of time, can be reopened without the need for surgical steps for reopening during testing. Material and methods. Four sheep were used, one being from the Control Group (GC) and 3 from the Test Group (GT). Each animal received eight implants located near the angle of the mandible, four on the left side and four on the right side, totaling 32 Acqua® 3.5 mm diameter 8.5 mm long implants of the company Neodent® that were evaluated by the resonance frequency analysis with the ISQ (Implant Stability Ratio) measurement using a transducer (SmartPeg) expressed on a scale of 0 to 100. For the Control Group (GC) the ISQ measurements were performed by the conventional method, where the SmartPeg was attached directly onto the implant platform. In the Test Group (GT) the studied device was attached to the implant so that the measurement could be performed. The periods studied were: immediately after surgery and four weeks of osseointegration. For the statistical analysis Wilcoxon and Man-Whitney tests were used, with a probability of 5% (p <0.05). Results. The averages obtained in the CG were 50.47 immediately after surgery and 65.68 after 4 weeks, while in the GT were 34.74 and 34.81, respectively. Comparing the difference between the groups in the means of immediate SAI and after four weeks, there was a significant difference with p = 0.0321 and p = 0.0027, respectively, demonstrating that the results in the WG in the two periods were not equivalent when compared to the CG. Conclusion. The results showed that the test group, despite having benefits in relation to the handling of the animals, did not present benefits in relation to the efficiency of the ISQ reading when compared to the conventional method.

Abstract:
Specimens were made from bovine ribs and milling divided into two groups (A - B mills in steel - mills in zirconia), each group was divided into four subgroups according to different settings milling (rotation and pressure milling). They were measured and compared the temperatures of the milling burs made by the two materials made using four different configurations. A prosthetic surveyor has been adapted to the study to connect a surgical electronic engine, counter angle driver for implants. A container was also coupled to one of the liner's arms to accommodate components metallic spheres of standard weight, sometimes 1.2kg, 2.4kg moment according to the configuration of each subgroup such that the surgical motor that ran milling in 1000 and 2000 rpm. In order to measure milling temperatures, they used two thermocouples of the same make and model in two depths milling, the first and the second 5mm to 15mm. All the cutters are subjected to washing and antisepsis every two tests. The heat generated by the friction between bone and surgical instrumentation during such drills tend to be imparted to this tissue degeneration resulting protein that cause scarring and can be decisive in higher failure rates. Several factors are potentially destined to contribute to increasing the temperature for the osteotomies of which insufficient irrigation, using worn drills, surgical instrumentation outside the standard suggested by the manufacturer and the material constituting the object of this study surgical drills.
Corpos de prova foram confeccionados a partir de costela bovina e as fresagens divididas em dois grupos (A – fresas em aço martensíntico e B – fresas em zircônia), cada grupo foi subdividido em quatro subgrupos de acordo com configurações diferentes de fresagem (rotação e pressão de fresagem). Foram aferidas e comparadas as temperaturas das fresagens realizadas por brocas confeccionadas nos dois materiais através de quatro configurações diferentes. Um delineador protético foi adaptado ao estudo para conectar-se um motor eletrônico cirúrgico, propulsor de contra ângulo para implantes. Um recipiente também foi acoplado a um dos braços do delineador para que acomodasse esferas metálicas componentes do peso padrão, ora 1,2kg, ora 2,4kg de acordo com a configuração de cada subgrupo tal qual o motor cirúrgico que executava fresagens em frequências de 1000 e 2000 rpm . Para mensuração das temperaturas de fresagem, foram utilizados dois termopares da mesma marca e modelo em duas profundidades de fresagem, a primeira a 5mm e a segunda a 15mm. Todas as fresas foram submetidas à lavagem e degermação a cada dois testes. O calor gerado através da fricção entre osso e brocas durante essas instrumentações cirúrgicas tende a ser transmitido a este tecido provocando degeneração proteica que acarretam cicatrizes e podem ser determinantes para taxas de insucesso mais altas. Diversos fatores estão potencialmente predestinados a contribuir com o aumento da temperatura durante as osteotomias dentre os quais, irrigação insuficiente, utilização de brocas desgastadas, instrumentação cirúrgica fora do padrão sugerido pelos fabricantes e material constituinte das brocas cirúrgicas-objeto desse estudo.

Com o aumento da expectativa de vida da população é importante o estudo de tratamentos alternativos e de biomateriais que visam auxiliar no processo de osseointegração em pessoas com osteoporose. O presente estudo avaliou e comparou a osseointegração de implantes cilíndricos de superfície porosa com implantes cilíndricos de superfície rugosa, ambos de titânio, em ratas osteopênicas e normais, por meio de análise histológica e histomorfométrica. Avaliou também a influência do tratamento com laser de baixa potência (Arseneto de Gálio Alumínio) sobre a osseointegração. Os implantes foram inseridos em 84 ratas, cada rata recebeu um implante poroso no fêmur esquerdo e um implante rugoso no direito. Quarenta e dois dos animais foram submetidos à cirurgia de ovariectomia (OVZ) e 42 foram falsamente operados (SHAM). Após um mês, as ratas foram divididas em 4 grupos, com 21 animais cada, de acordo com o tratamento recebido: a) grupo 1 (SHAM): cirurgia de colocação dos implantes (CI); b) grupo 2 (SHAM): CI e aplicação do laser de baixa potência (LLLT); c) grupo 3 (OVZ): CI; d) grupo 4 (OVZ): CI e LLLT. Sete animais de cada grupo, selecionados aleatoriamente, foram sacrificados 2, 4 e 6 semanas após a cirurgia, os fêmures contendo os implantes foram submetidos à análise histológica e histomorfométrica. Na análise histológica observou-se que houve osseointegração em ambos implantes nos diferentes grupos. Após avaliação da análise histomorfométrica verificou-se que o grupo 4, os implantes do tipo poroso, com animais sacrificados 4 semanas após a cirurgia de implante exibiu maior porcentagem de neoformação óssea, seguido do grupo 2, com implante poroso 4 e 6 semanas de período de sacrifício. Concluiu-se que a laserterapia melhora significantemente a neoformação óssea e que os implantes de superfície porosa apresentam maior área para contato na interface osso-implante.
With increasing life expectancy of the population is important to the study of alternative treatments and biomaterials which aim to assist in the process of osseointegration in people with osteoporosis. .This study involved an assessment and comparison of the osseointegration of cylindrical titanium implants with porous surfaces and with rough surfaces in osteopenic rats, based histological and histomorphometric analyses. An evaluation was also made of the influence of low level laser therapy (LLLT) with gallium-aluminum arsenate (Ga-Al-As) on osseointegration. The implants were placed in 84 rats, two per rat, i.e., a porous implant in the left femur and a rough implant in the right femur Forty-two of the animals were then ovariectomized (OVZ) while the other 42 were subjected to a sham ovariectomy (SHAM). After one month the rats were divided randomly into four groups of 21 animals each, according to treatment received: a) group 1 (SHAM) implant surgery (IS); b) group 2 (SHAM) IS and low-level laser therapy (LLLT); c) group 3 (OVZ): IS; d) group 4 (OVZ) IS and LLLT. Seven animals from each group were selected randomly and killed 2, 4 and 6 weeks after surgery and the histomorphometric analyses. The histological analysis revealed that osseointegration occurred in both types of implants in all the groups. The histomorphometric analysis indicated that the porous implants in the group 4, killed 4 weeks after implantation, showed the highest percentage of new bone formation, followed by the porous implants in group 2, killed 4 and 6 weeks after implantation. It was concluded that laser therapy significantly improves new bone formation and that implants with porous surfaces have a larger contact area at the bone-implant interface.

Abstract:
A literature review of medical implant applications of mesoporous silica films was written, highlighting the advantages and limitations of different film synthesis methods. Both films synthesized through the EISA sol-gel method and particulate films, including those synthesized through the direct growth method, were reviewed and discussed. All films were found to have their strengths and weaknesses, however, the films synthesized through the direct growth method was found to be the most promising type for coating implants. In addition to the literature review, copper-doped mesoporous silica films were synthesized on titanium grade 2 substrates. SEM shows that particles grown on all the films and EDX elemental analysis confirms the presence of copper in the material. Nitrogen physisorption measurements show that particles with incorporated copper have a higher specific surface area, and pore volume compared to un-doped particles. No copper content could be confirmed through FTIR. The particles grown on titanium substrates were more rod-like compared to the ones grown on the silicon substrates as control.

Abstract:
AbstractOver the past decades, implant dentistry has evolved to be a very predictable treatment modality for the replacement of lost teeth and has now become one of the most common oral surgical procedures carried out worldwide. This chapter introduces the history and evolution of dental implants, discusses the concept of osseointegration, mentions the types of implants and discusses clinical decision making and execution of straight forward implant placement. It must be noted that the field of implantology is rapidly developing with new treatment concepts and increasing use of digital technology. The surgical part of implant treatment although extremely important, is only a part of the overall treatment, the other important factors being the laboratory and prosthodontics. This chapter only provides a basic surgical overview of implantology for the beginner surgeon clinician.

Abstract:
The process of osseointegration is the firm anchoring of a surgical implant by the growth of bone around it without fibrous tissue formation at the interface. This process is critical for long-term implant success. The ability to monitor this process in vivo would allow for personalization of loading protocols to increase the rate of implant success overall by ensuring that implants are not over or under loaded during recovery. Accordingly, there is a strong need for an instrument that has the sensitivity to noninvasively measure osseointegration in vivo. One of the objectives of the present study was to assess the performance of an instrumented percussion probe for quantitatively monitoring the osseointegration process.

Abstract:
Abstract The clinical success of bone-interfacing orthopaedic and dental implants is dependent on adequate fixation of the implant by mechanical interlock with ingrown bone tissue (i.e., functional osseointegration). The rate and reliability with which osseointegration is achieved are influenced by a number of factors, including the surface geometry of the implant (Thomas and Cook, 1985; Simmons et al., 1999). However, the mechanisms by which implant surface geometry influences initial bone formation remain unresolved. Identifying the factors that allow bone-interfacing implants to osseointegrate more rapidly and reliably should lead to improvements in their use and design.

Abstract:
It is important to have a quantitative method to establish a standard way to measure stability and osseointegration of implants. Among other benefits, these measurements would provide information leading to the prediction of healing time around the implant and the monitoring of the health of the implant’s interface. The dental industry has been looking for non-destructive methods to measure implant integration within the bone. In previous studies, resonance frequency analysis revealed a clear relationship between resonance frequency measurements and stiffness of the implant interface and the effective length of the implant. These studies have examined only one mode of vibration or have suffered from measurement difficulties. Furthermore, no study has evaluated the damping properties of the interface and surrounding tissues. This paper describes the development of an instrument capable of capturing and measuring information to characterize the process of dental implant osseointergration. The parameters needed to measure stability and osseointegration of implants are the stiffness of the implant components (which are a function of their geometry and material composition) and the stiffness and damping properties of the implant-bone interface and surrounding tissues. The instrument developed provides valuable information about the stiffness and damping properties of the implant-bone interface obtained through resonance frequency analysis with torsional, longitudinal and transverse vibration. Experimental, analytical, and finite element analysis results are presented.

Abstract:
Osseointegrated prostheses are widely used as the treatment for femur amputation. However, this technique requires sufficient implant stability before and during the rehabilitation period to mitigate the risk of implant breakage and loosening. Hence, reliable assessment methods for the osseointegration process are essential to ensure initial and long-term implant stability. This paper aims to investigate a vibration analysis method with a novel implant design, which focuses on the analysis of the dynamic response of the femur-implant system during the simulated osseointegration process. The paper also proposes a concept of using normalized energy difference to formulate an energy index (E-index). A 133mm-long amputated artificial femur model was constrained at the proximal end with a customized clamp. The epoxy adhesives were applied at the interface between the aforementioned femur and implant to simulate the change in stiffness in mimicking the osseointegration process. A two-unidirectionalsensor setup attached to the bottom of the implant was used to record the dynamic response stimulated by an impact hammer. The results show a significant change in magnitude of the cross-spectrum during the osseointegration processes. The resonance modes in cross-spectrum for the frequency above 1000Hz are hard to distinguish suggested that the vibration of the system being hindered by the high dampening effect of the adhesive before the initial bonding of the adhesive at 300s. The plot of E-index shows a clear correlation that the E-index provided a potential quantitative approach for monitoring the stages of osseointegration. These findings highlight the feasibility of using the vibration analysis technique and E-index to quantitatively monitor the osseointegration process for future improvement on the efficiency of human health monitoring and patient rehabilitation.

Abstract:
Abstract Dental implants are a prosthesis for missing teeth that are made to match a natural tooth. Current dental implants experience a high risk of failure in patients that have diseases affecting the oral region. When the patient experiences one or more of these diseases, the interface between the bone and implant is compromised and patients can experience low success rates or insufficient remaining bone structure. The purpose of this research is to create a dental implant technology that is suitable for both healthy and unhealthy patients. In the solutions studied, inducing pores into the Ti6Al4V implant proved to mimic the material properties of natural bone resulting in enhanced osseointegration. We plan to create an innovative solution with enhanced osseointegration that will ensure a gradient in mechanical properties. The complex geometry of the pore-induced dental implant is manufactured using the additive manufacturing method of selective laser melting (SLM). In this research, a functionally graded porous disk was designed using lattice-like pores to mimic the structure of bone. Multiple samples were created with 50-micron pores and printing was studied to test the capabilities of the SLM machine and resolution of the samples. It was found that the parameters play a role in the print resolution of the design. Additional porosity was induced through a keyhole effect during selective melting process.

Review question / Objective: Does the bioactive surface of titanium dental implants, based on biomolecules, influence osseointegration?. The aim of our study was to evaluate the role and efficacy of bioactive surfaces in osseointegration. Our review study limited the research interest to titanium dental implants coated with a biomolecule, i.e., an organic molecule produced by a living organism. Condition being studied: In recent years, much attention has been paid to topographical modifications of dental implant surfaces, as well as to their coating with biologically active substances.a bioactive surface is one capable of achieving faster and higher quality osseointegration, shortening waiting times and solving situations of poor bone quality. Molecules that can be applied for bioactive purposes include bioceramics, ions and biomolecules. Collagen and bone morphogenetic protein have been suggested as bone stimulating agents. Biofunctionalization of the implant surface with a biomimetic active peptide has also been shown to result in a significant increase in bone-to-implant ratios and an increase in peri-implant bone density.

Abstract:
Review question / Objective: - Does the osseodensification drilling technique increase primary stability in low-density bone? - The aim of the present investigation was to evaluate primary stability in dental implants in people with low density bone using the osseodensification technique. Condition being studied: The replacement of missing teeth through dental implants is currently the most practiced in dental clinics. The main criterion for determining the success of an implant is osseointegration, which is a direct structural and functional connection between vital bone and the prosthetic load-bearing surface of an implant. In the same way, primary stability must be obtained for a good lasting clinical result of the implant and to achieve this purpose, the bone density must be evaluated where the dental implant is to be placed. Salah Huwais in 2013 introduced a new osteotomy procedure (Oseodensification) for site preparation without removal and bone preservation. The Osseodensification process produces an autograft layer around the implant with the osteotomy surface, the autologous bone comes into contact through an endosteal device that accelerates osseointegration due to the nucleation of osteoblasts in the instrumented bone adjacent to the implant and has a greater primary stability due to contact between the device and the bone.
