AbstractAs the reversible contraceptive arm implants grow more popular, there is an increasing need to recognize the complications resulting from implant migration and removal. This review summarizes the findings of imaging and removal methods. When an implant is lost, the axillary region should be investigated first. If the implant still cannot be found, visualization though different methods have been employed for non-radiopaque implants. Real-time fluoroscopic-guided localization and removal can be accomplished for radiopaque Nexplanon. Once the implant has been located, standard removal method and other modified techniques can be used to safely remove the implant depending on the implant's location.

Patients with total edentulism can be treated with fixed or mo- bile prosthetic implant rehabilitation with dental implants as part of implanto-prosthetic therapy. Of the three dental implant loading options/protocols (conventional, early loading, and im- mediate loading), removable prosthetic works are most often conventionally loaded and then they represent standard and reliable forms (with a high success rate) of implanto-prosthetic therapy.

The present research study seeks to provide a thorough literature evaluation on implant-based materials, implant design and application of FEA approach (Finite Element Analysis). PEEK biomaterial is the primary subject of this article. Implant design and the significance of PEEK material in future clinical applications are significant subtopics in this study. Due to its excellent physical qualities, titanium plays an essential part in the implant business. PEEK and zirconia materials appear to have promise for the future. Biomedical uses of PEEK and its composite materials in a number of different fields, including dentistry, hip implant, anterior plate fixation, crainoplasticity, knee implants, spine implants, and so forth. The implant's impact and success are greatly impacted by the prudent selection of implant biomaterial. Before the PEEK implant can replace titanium and zirconium, further research and well-controlled clinical studies are required. In this study, a number of biomaterials that were used in the implant industry will be finalized.

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.

Full textAbstract:
Objectives: The aim of this retrospective study was to investigate possible risk factors for early implant failure in screw retained fixed full-arch rehabilitation. Methods: data of 487 patients (2323 implants) treated with full-arch rehabilitation supported by same implants brand were collected for the time period from 2017 to 2020 and examined to evaluate early implants failure rates. The following data were collected for statistical analysis: sex, age, health disorders (diabetes and hypertension) and bad habit (smoke) of the patient, location of the implant (maxilla or mandible, anterior or posterior site), type of implant's healing and bone regeneration procedures. Chi-squared test, bivariate comparison analysis and univariate mixed model analysis were used to estimate the effect of both patient-related and implant related variables on early implant failure as a potential risk factors. Results: 487 patients were included, 218 females (62.3 ± 9.14 of age) and 269 males (62.8 ± 10.11 of age) in 30 private institutions for a total of 2323 implants placed and a total of 526 screw retained fixed full arch rehabilitation. A total of 40 out of 2323 (1.7%) implants failed prematurely within 1 year, 32 in the maxilla 8 in the mandible. Bivariate comparison analysis and univariate mixed model analysis showed that female patient, implant placed in maxilla, age <61 years and submerged healed implants showed a statistically significant higher failure rate among the risk factors considered. Conclusions: Implants placed in the upper jaw and their modality of healing seems to be associated with a higher risk of early implant failure.

(2) To classify the possible reasons for device failure in cases reported for each implant. (3) To examine any differences between reasons for pregnancies associated with these products.Study designExtraction of data from the UK spontaneous reporting system for adverse drug reactions in relation to etonogestrel implants. Reports indicating pregnancy were identified for the periods 2005–2009 (Implanon) and 2012–2016 (Nexplanon). Possible reasons for failure of the method in each reported case were assigned to one of eight predetermined categories.ResultsAfter exclusions, 229 Implanon and 234 Nexplanon cases contained sufficient information for analysis. True method failures accounted for a majority of the pregnancies in those using contraceptive implants (58%); the next most common cause was missing implants (26% of pregnancies). In all categories of cases, there was no difference in frequency of pregnancy when the two time periods were compared.ConclusionsThere is still potential for greater avoidance of pregnancies associated with etonogestrel implant use.ImplicationsThis study underscores the continuing need for taking a full drug history, timing the insertion on days 1–5 or according to recommended quick starting routines and palpating the arm after implant insertion.

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.

Neste trabalho é feita uma revisão da literatura e uma comparação em relação aos dois tipos de retenção de prótese fixas implanto‒suportadas. Para isso foram analisados vários fatores com influência no sucesso ou insucesso dos dois tipos de restaurações como: estética, oclusão, resistência, retenção, biomecânica, reversibilidade, ajuste passivo, efeitos biológicos, provisionalização, função imediata e hábitos parafuncionais. A resposta a esta discussão só é possível de ser obtida após uma exaustiva avaliação de cada caso de reabilitação, ponderando as vantagens e desvantagens de cada técnica, não havendo uma resposta geral para a questão de qual o melhor tipo de retenção. The search for oral rehabilitations more and more close from the natural teeth had contributed for the evolution of the oral rehabilitation techniques, namely in the implantology field, where nowadays are lifted several paradigms, among which is the discussion among the use of cement‒retained or screw‒retained prostheses. In this work it is done a literature review and a comparison in relation to the both types of implant‒supported fixed prostheses retention.For that propose several factors with influence on the success or failure of the both type of restorations were analyzed, such as: aesthetics, occlusion, resistance, retention, biomechanics, retrievability, passivity, biological effects, provisionals, immediate function and parafunctional activity. The answer to this discussion it’s only obtained after an exhaustive evaluation of each rehabilitation case, considering the advantages and disadvantages of each technique, without having a general answer for the question which is the best type of retention.

Um aspecto crítico que afeta o sucesso ou falha de um implante é a maneira pela qual as tensões são transferidas do implante ao tecido ósseo. A sobrecarga na prótese dentária pode levar a perda da osseointegração, dessa forma, é aconselhável evitar altas concentrações de tensões no osso de suporte, do ponto de vista clínico. Entretanto, o estresse mecânico pode ter consequências positivas ou negativas no tecido ósseo, fatores esses dependentes de vários fatores associados que podem ser mecânicos ou biológicos. Portanto, o propósito do presente estudo foi analisar a influência da qualidade óssea na distribuição das tensões em próteses unitárias implantossuportadas com diferentes tipos de conexão protética, pelo método dos elementos finitos tridimensionais. Para isso, foram confeccionados doze modelos tridimensionais com o auxílio dos programas de modelagem gráfica SolidWorks 2010 e Rhinoceros 4.0, além do programa InVesalius. Cada modelo foi composto por um bloco com diferentes qualidades ósseas (Tipo I, II, III e IV) e a presença de um implante (4,0x10 mm) com diferente tipo de conexão (Hexágono externo, interno e cone Morse), com coroa metalo-cerâmica. Após geração de geometrias, os modelos foram importados para o programa de pré e pós processamento de elementos finitos FEMAP 10.2, onde foram geradas as malhas de elementos finitos, condições de carregamento e contorno. A carga aplicada foi de 200N axialmente e 100N obliquamente, na superfície oclusal das coroas. Essa carga total foi dividida entre as cúspides (4 para a carga axial e as duas linguais para a carga oblíqua). Em seguida, a análise foi gerada no programa FEMAP 10.2 e exportada para cálculo no programa de elementos finitos...
A critical issue that affects the success or failure of an implant is the manner in which the stresses are transferred from the implant to bone tissue. The overload can lead the dental implant to loss of osseointegration, thus it is advisable to avoid high stress concentrations in bone support, according to the clinical point of view. However, mechanical stress can bring positive or negative consequences in the bone tissue and these factors depend on association with mechanical or biological factors. Therefore, the purpose of this study was to analyze the influence of bone quality on stress distribution in implant-prosthesis unit with different types of prosthetic connection, by the three-dimensional finite element method. For this, twelve three-dimensional models were made with the aid of SolidWorks 2010 and Rhinoceros 4.0, graphical modeling software, besides the InVesalius. Each model was composed of a block with different bone qualities (Type I, II, III and IV), an implant (4.0 x 10 mm) with different type of prosthetic connection (Hexagon external, internal and Morse taper) and metal ceramic crown. After generation of geometries, the models were imported into FEMAP 10.2, the pre and post-processing finite element software, where it was generated finite element meshes, boundary and loading conditions. The 200N load was applied axially and 100N obliquely on the occlusal surface of crowns. This total load was divided among the cusps (four points for the axial load and two points for the oblique load on the lingual cusps). Then, the analysis was generated in the FEMAP 10.2 and exported to the NeiNastran version 9.2 software for calculation in finite element analysis, running on a workstation. The results were imported back to the FEMAP 10.2 for viewing and post-processing maps of von Mises stress and... (Complete abstract click electronic access below)

INTRODUÇÃO: A qualidade da interface osso-implante pode ser influenciada diretamente por aspectos inerentes ao tratamento da superfície do titânio e determina a forma que as células interagem, aderem e se fixam a ela, podendo potencializar e encurtar o tempo de osseointegração. Este estudo propôs-se a analisar alterações na osseointegração produzidas pela hidrofibilidade das superfícies dos implantes Neoss®. MATERIAIS E MÉTODOS: Foram utilizados 6 cães da raça labrador e instalados 44 implantes Neoss® bilateralmente na mandíbula com defeitos ósseos padronizados na região coronal: 22 implantes apresentavam superfície ProActive (hidrofílica) e outros 22 implantes eram de superfície Bimodal (hidrofóbica). Foram avaliados a resposta biológica nos períodos de uma semana e quatro semanas de osseointegração, utilizando parâmetros histológicos, histomorfométricos, fluorescência e de estabilidade mecânica aferido pelo método de análise de frequência de ressonância (RFA). As superfícies também foram submetidas à análise topográfica por interferometria óptica e quanto a propriedade de hidrofibilidade. RESULTADOS: Nos testes topográficos, a superfície ProActive apresentou valor de Sa de 0,4m contra Sa de 0,8m da superfície Bimodal, sugerindo menor rugosidade da superfície hidrofílica. A umectibillidade da superfície foi maior no grupo ProActive, exibindo valores de ângulos de contato de 27,2° contra 67,2° da superfície Bimodal. Ambas as superfícies apresentaram valores semelhantes nos períodos de uma e quatro semanas no que diz respeito à estabilidade mecânica do implante, aferidos com o RFA e nos parâmetros histomorfométricos em relação deposição óssea ao seu redor CONCLUSÕES: 1) A superfície ProActive apresentou valores menores de rugosidade e aumento da umectibilidade em relação aos implantes com superfície Bimodal. 2) A superfície ProActive utilizada no presente estudo não favoreceu os eventos de osseointegração nas condições períodos de 1 e 4 semanas avaliados. 3) Após 4 semanas de osseointegração, ocorreu aumento da estabilidade dos implantes instalados sem haver diferença entre as superfícies ProActive e Bimodal. 4) A estabilidade dos implantes, avaliados por meio do RFA, aumentou gradativamente durante a osseointegração, sem haver diferença entre as superfícies testadas.INTRODUCTION: The quality of the bone-implant interface can be directly influenced by factors inherent to titanium surface treatment which determines cells interaction and adherence to shortening the time for osseointegration. This study aimed to assess changes on osseointegration produced by the hidrophibility of Neoss® implants surfaces. MATERIALS AND METHODS: Six labrador dogs were used and 44 Neoss® implants bilaterally installed in the mandible (ProActive with hydrophilic surface) and (Bimodal hydrophobic surface), in standardized bone defects in the coronal region. The biological responses in one and four weeks of osseointegration were evaluated using histological, histomorphometric, fluorescence analysis and mechanical stability measured by Resonance Frequency Analysis (RFA). The surfaces were also subjected to topographic analysis by optical interferometry and hydrophobicity by wettability analysis. RESULTS: The topographic surfaces test showed value of 0.4 micrometers for ProActive implants, against 0.8 micrometers for Bimodal implants, suggesting less hydrophilic surface roughness in the former (p0.05). The wettability values were higher in ProActive surface, with contact angles of 27.2° versus 67.2° of the Bimodal surface (p0.05). Both implant surfaces exhibited similar mechanical stability measured by RFA, as well as the histomorphometric parameters related to bone deposition onto the surfaces. CONCLUSIONS: 1) The ProActive surface showed lower roughness values and increased wettability compared to Bimodal surface. 2) The ProActive surface did not favor osseointegration at 1 and 4 weeks. 3) After 4 weeks of osseointegration the implants increased in stability, with no statistical differences between Bimodal and ProActive surfaces

Próteses implantossuportadas estão sujeitas a diversos tipos de falhas, sendo o afrouxamento do parafuso de retenção a complicação mais frequente, devido à perda da pré-carga inicial. A perda da pré-carga pode ser influenciada por fatores como incidência de cargas oclusais impróprias, diferentes tipos de conexões do sistema implante/prótese e desajustes entre a coroa e o implante. Sendo assim, este estudo teve como objetivo avaliar a manutenção da pré-carga de parafusos de retenção de titânio e a desadaptação vertical de coroas protéticas parafusadas, antes e após a ciclagem mecânica. Para isso, três tipos de conexões implante/pilar foram utilizados: implantes de conexão interna híbrida com pilar do tipo esteticone (grupo CIE); implantes de conexão externa com pilar o tipo esteticone (grupo CEE); e implantes de conexão externa com pilar UCLA (grupo CEU). Para cada grupo, foram confeccionadas 10 coroas metálicas fundidas em liga de CoCrMo para a composição final dos corpos-de-prova. Os parafusos de retenção protéticos receberam torque de 20N.cm nos grupos CIE e CEE e 30N.cm no grupo CEU, e, após três minutos, foi mensurado o valor de destorque inicial, com o auxílio de um torquímetro analógico. Após essa avaliação inicial, as coroas receberam novamente o torque recomendado e foram submetidas ao ensaio de ciclagem mecânica, com carga oblíqua (30°) de 130N ± 10N, a 2Hz de freqüência, totalizando 1x106 ciclos. Após a ciclagem, foi mensurado o destorque final. Além disso, antes e depois da ciclagem mecânica, foi realizada a verificação da adaptação vertical das coroas por meio de um estereomicroscópio, com as coroas parafusadas a um único implante e posicionadas em uma matriz de silicone...
Implant-supported prostheses are prone to several types of fail, and the retaining screw loosening is the most frequent complication, due to the loss of its initial preload. Loss of preload may be caused by different factors such as the incidence of excessive occlusal loading, different types of implant/prosthesis connections systems and vertical misfit between crown and implant. Thus, the aim of this study was to evaluate the preload maintenance of titanium retaining screws and to measure the vertical misfit of implant-supported screwed crowns, before and after mechanical cycling. For this purpose, three types of implant/abutment systems were embedded in polyester resin: internal hybrid connection implants and Estheticone abutments (Group ICE); external connection implants with Estheticone abutments (Group ECE); and external connection implants with UCLA abutments (Group ECU). For each group, 10 metallic crowns were cast in CoCrMo alloy for the final compositions of the specimens. Retaining screws received insertion torque of 20 N.cm in groups ICE and ECE and 30N.cm in group ECU, and, after three minutes, the initial detorque was measured through an analogical torquemeter. After this initial evaluation, crowns were retightened and submitted to cyclic loading test, with an oblique loading (30°) of 130N ± 10N, at 2Hz of frequency, totalizing 1x106 cycles. After cycling, final detorque was measured. Moreover, before and after mechanical cycling, the vertical misfit of the crowns was measured through estereomicroscopy, with the crowns screwed to a single implant and positioned into a silicone matrix. The data obtained were tabulated and submitted to variance analysis, Fisher’s exact test and Pearson’s linear... (Complete abstract click electronic access below)

Este estudo propôs-se analisar qualitativamente a topografia e arquitetura de diferentes superfícies de implantes dentários, compará-las, descrevê-las e correlacioná-las com os possíveis eventos moleculares e celulares iniciais da osseointegração. MATERIAIS E MÉTODOS: cinco implantes com diferentes tratamentos de superfície foram analisados em três diferentes áreas: apical, região de roscas (topos, flancos e vales) e região cervical por microscopia eletrônica de varredura (MEV) e topo do ápice em microscopia de força atômica (MFA). RESULTADOS: as superfícies dos implantes NanoTite®, SLA® e Xive® TG plus, no MEV, são semelhantes pelo seu aspecto de lacunas, diferindo no plano superficial; a superfície do implantes TiUnite® apresenta características coraliformes/vulcanoides, enquanto a do implante Exopro® apresenta estrias em formas de pequenos sulcos. A rugosidade média (Ra) à MFA, apresentou-se maior no implante TiUnite®, seguido pelos implantes Xive®TG plus, NanoTite®, Exopro® e SLA®. A área analisada se restringe a pequenos pontos (nanométricos), que não possibilita uma visão panorâmica de todas as estruturas (micrométricas), e consequentemente não permite uma real comparação da rugosidade. CONCLUSÕES: a metodologia ideal para análise das superfícies com o objetivo de compreender como as células às colonizam e se aderem deve ser em escala micrométrica, destacando-se à MEV em detrimento da MFA. As duas metodologias, MEV e MFA, são fundamentais na análise de superfície de implantes dentários, porém devem ser conjuntamente e/ou simultaneamente empregadas. A MFA parece ser a mais adequada para estudos que visem a interação da superfície dos implantes com estrutura de nível molecular e à MEV, no nível celular. Cada tratamento de superfície promove um tipo específico de topografia, cujos benefícios moleculares, teciduais e clínicos devem ser estudados caso a caso.Introduction: Bone-implant interface quality may be influenced by surface roughness and determines how cells interact, cling to and fix to, therefore can enhance and shorten the time for osseointegration. This study aims to analyze qualitatively the topography and architecture of different dental implants surfaces, to compare and describe them. MATERIALS AND METHODS: five implants with different surface treatments were evaluated in three different areas: apical, region of threads (tops, sides and valleys) and cervical region by scanning electron microscopy (SEM) and atomic force microscopy (AFM), correlating the possible molecular and cellular initials events of osseointegration. RESULTS: the surfaces of the implants NanoTite®, SLA® and ® Xive® TG plus, in the SEM, are similar by their appearance of gaps, although they differ in surface plane; the surface of TiUnite® implants have features such as corals and/or volcanos, while the implant Exopro ® has stretch marks in form of small grooves. The average roughness (Ra) to the AFM, appeared higher in TiUnite ® implant, followed by Xive® TG plus NanoTite®, Exopro® and SLA® implants. The area analyzed in the AFM, is restricted to small points (nanometrics), and do not allow denote a panoramic view of all structures (micrometrics), not allowing a real comparison of surface roughness. CONCLUSIONS: the optimal methodology for surfaces analysis with the objective of understanding how the cells colonize and fix to dental implants should be in the micrometer scale, highlighting the SEM over AFM. The AFM seems to be most suitable for studies aiming the interaction of the implant surface with molecular-level and SEM at the cellular level. Each treatment promotes a specific surface topography whose benefits molecular, tissue, and clinical should be studied separately.

Assim, foi proposto avaliar a efetividade de parafusos de liga de titânio com e sem tratamento de superfície sobre a estabilidade de pilares em zircônia (ZrO2) após carga cíclica, bem como observar alterações estruturais por meio de microscopia eletrônica de varredura (MEV). Para isso, 20 pilares UCLA em ZrO2 foram fixados sobre implantes do tipo hexágono externo com torque de 20 Ncm e divididos em 2 grupos (n=10), conforme o parafuso do pilar: (A) pilar-implante e parafuso de liga de titânio (Ti); (B) pilar-implante e parafuso de liga de titânio com cobertura Diamond Like Carbon (DLC/Ti). O valor do torque reverso (pré-carga) foi mensurado antes e após o carregamento. O teste foi realizado de acordo com a norma ISO 14801. Cargas cíclicas (0,5 x 106; 15 Hz) entre 11 - 211 N foram aplicadas com 30º de inclinação em relação ao longo eixo dos implantes. As médias dos grupos foram calculadas e comparadas utilizando análise de variância de dois fatores e testes F (α=0,05). Os resultados mostraram que antes do carregamento a média do grupo Ti foi significativamente maior que a do grupo DLC/Ti (p=0,021). Após o carregamento ambas as médias 14 diminuíram significativamente, sem diferença significante entre elas (p=0,499). As imagens obtidas na MEV revelaram micro-fraturas na base de assentamento do pilar. Nas condições estudadas, concluiu-se que: (1) os parafusos estudados apresentaram efetividade similar com relação à manutenção da pré-carga; (2) a redução significativa no torque reverso e os danos observados na MEV indicam que o acompanhamento dos pacientes é necessário para assegurar a longevidade das restaurações de ZrO2 implanto-suportadas.
In an attempt to prevent screw-loosening problem, abutment screws with surface treatment were developed. Thus, the aim of the current study was to evaluate comparatively the effectiveness of titanium alloy coated screws and noncoated screws on the stability of ZrO2-ceramic abutments after cyclic loading, as soon as observe possible microdamaging in the structure of the components using a scanning electron microscope (SEM). For this, 20 prefabricated ZrO2-ceramic UCLA abutments were tightened to 20 Ncm on their respective external hex implants and divided equally into 2 groups (n=10), according to the type of screws used: (A) implant-abutment and noncoated titanium alloy screw (Ti); (B) implant–abutment and titanium alloy screw with Diamond Like Carbon surface coating (DLC/Ti). The reverse torque value (preload) of the abutment screw was measured before and after loading. The tests were performed according to ISO norm 14801. A cyclic loading (0,5 x 106; 15 Hz) between 11 - 211 N was applied at an angle of 30 degrees to the long axis of the implants. Group means were calculated and compared using ANOVA and F tests (α=0,05). The results showed that before cyclic loading, the mean of Ti group was significantly higher than the DLC/Ti group (p=0,021). After cyclic loading, both means decreased significantly, with no significant differences 16 between them (p=0,499). Under the studied conditions, it can be concluded that: (1) the two abutment screw types presented similar effectiveness in maintaining preload; (2) the significant decrease in reverse torque values and the microdamaging detected at SEM analysis indicate that patient follow-up is needed to ensure the integrity of the ZrO2-ceramic single-implant restorations.

O comportamento biomecânico de um implante dentário osseointegrado desempenha um importante papel na sua longevidade funcional. As limitações anatômicas às vezes tornam necessário o posicionamento de implantes com angulações fora do considerado ideal para as reabilitações protéticas, havendo maior concentração de tensões e reabsorção no osso cortical ao redor do implante. Para solucionar tais situações o profissional deve lançar mão de um cuidadoso planejamento e uso de intermediários angulados, estudando qual conexão protética melhor se adapta a situação clínica. Portanto, o propósito do presente estudo foi analisar a influência da angulação dos implantes com diferentes tipos de conexão protética na distribuição de tensões, pelo método dos elementos finitos tridimensionais. Para isso, foram confeccionados seis modelos tridimensionais com o auxílio dos programas de modelagem gráfica SolidWorks 2010 e Rhinoceros 4.0, além do programa InVesalius. Cada modelo foi composto por um bloco ósseo e a presença de um implante (4,0x10 mm) com diferentes angulações (0º, 17º e 30º) e tipos de conexão (Hexágono externo e cone morse), com coroa metalo-cerâmica. Após geração das geometrias, os modelos foram importados para o programa de pré e pós-processamento de elementos finitos FEMAP 10.2, onde foram geradas as malhas de elementos finitos, condições de carregamento e contorno. A carga aplicada foi de 200N axialmente e 100N obliquamente, na superfície oclusal das coroas. Essa carga total foi dividida entre as cúspides (quatro para a carga axial e as duas linguais para a carga oblíqua). Em seguida, a análise foi gerada no programa FEMAP 10.2 e exportada para cálculo no programa de elementos finitos NeiNastran versão 9.2, executada em uma estação de trabalho...
The biomechanical behavior of an osseointegrated dental implant plays an important role in the longevity. The anatomical limitations sometimes require the placement of implants with angles outside the considered ideal for prosthetic rehabilitation, with higher stress concentration and resorption in cortical bone around the implant. Thus, in some situations, the professional should planning careful the treatment and use the abutment, analyzing the prosthetic connection which best fits the clinical situation. Therefore, the purpose of this study was to analyze the influence of the implant angulation with different types of prosthetic connection on the stress distribution, by three-dimensional finite element method. Six three-dimensional models were made with the aid of the graphical modeling and SolidWorks 2010 Rhinoceros 4.0 and InVesalius.Each model was composed of a bone blockwith an implant (4.0 x 10 mm) with different angulations (0, 17 and 30) and connection types (Hexagon external and Morse taper) with metal-ceramic crown. After generation of the geometries, the models were imported into the pre-and post-processing finite element FEMAP 10.2, where we generated finite element meshes, boundary and loading conditions. The load was applied axial 200N and 100N obliquely to the occlusal surface of crowns. This total load was divided between the cusps (four for the axial load and two oblique lingual to the load). Then, the analysis was generated in and exported 10.2 FEMAP software for calculation in finite element program NeiNastran version 9.2, running on a workstation. The results were imported back to the FEMAP 10.2 for viewing and post-processing maps of von Mises stress and maximum principal stress. The maps for...

A utilização de implantes osseointegráveis e componentes protéticos tornaram-se recursos muito viáveis à resolução de casos simples e complexos na odontologia reabilitadora. No entanto, a junção implante componente pode apresentar problemas, tais como a presença de um microgap entre essas partes constituintes. Assim, vários materiais tem sido testados na tentativa de obstruir esse espaço, com resultados controversos. O objetivo deste estudo foi avaliar in vitro o comportamento de um adesivo anaeróbico (Loctite® 510, Henkel Ltda) monocomponente, de alta resistência e inerte, na vedação do microgap impedindo a passagem bacteriana do meio externo para o interno do conjunto. Foram utilizados 90 implantes de conexão externa hexagonal (n = 30), conexão interna hexagonal (n = 30) e conexão interna cônica (n = 30), divididos em Grupo Controle (n = 45) e Grupo Teste (n = 45). Os implantes foram abertos em fluxo laminar e cada unidade recebeu 3l de BHI estéril internamente. Sobre cada unidade era parafusado um componente protético especifico para cada marca e com torques recomendados pelos fabricantes com torquímetro digital. Os conjuntos Teste receberam ainda uma fina camada de adesivo que era aplicada com microbrush entre as partes; e todas as unidades dos grupos Controle e Teste foram vedados com material obturador provisório na sua porção mais coronal. Cada conjunto foi então imerso em 75 l de Enterococcus faecalis (ATCC 29212) em minitubos até o limite entre a junção implante/componente protético. Todas as amostras foram incubadas em estufa bacteriológica por 7, 14 e 28 dias a 37oC antes de serem reabertas. Após o período proposto, o conteúdo interno dos implantes foi coletado com cones de papel estéreis, diluído e semeado em placas de Petri, incubadas por 48 horas. Houve diferença significante entre o grupo teste e controle no grupo de conexão externa hexagonal, em todos os tempos (Teste de Fischer e Qui-quadrado, p 0.05). O adesivo anaeróbico testado funciona como barreira, não permitindo a migração de bactérias para o meio interno do conjunto implante/componente protético.The use of dental implants and prosthetic components have become very feasible resources to solve simple and complex cases in rehabilitation dentistry. However, the implant component junction may present problems, such as the presence of a microgap between these components parts.Therefore, several materials have been tested in an attempt to obstruct this space, with controversial results. The objective of this study was to evaluate in vitro the behavior of an anaerobic monocomponent adhesive (Loctite® 510, Henkel Ltda), high resistance and inert characteristics, in the microgap seal preventing bacterial passage from the external side to the inner side of the assembly. A total of 90 implants were used, with hexagonal external connection (n = 30), internal hexagonal connection (n = 30) and internal conical connection (n = 30) divided into Control Group (n = 45). Implants were opened in laminar flow cabinet and each unit received 3l of sterile BHI internally. On each unit a specific prosthetic component was screwed in for each brand and with torques recommended by the manufacturers with digital torque wrench. The sets of Test also received a thin layer of adhesive that was applied with microbrush between the parts; and all units of the Control and Test groups were sealed with provisional obturator material in their most coronal portion. Each set was immersed in 75 l of Enterococcus faecalis (ATCC - 29212) in mini-tubes to the limit between the implant / prosthetic component junction. All samples were incubated in a bacteriological incubator for 7, 14 and 28 days at 37oC before being reopened. After the proposed period, the internal contents of the implants were collected with sterile paper cones, diluted and seeded in Petri dishes, incubated for 48 hours. There was a significant difference between the test and control groups in the hexagonal external connection group at all times (Fischer and Chi-square test, p 0.05). The anaerobic adhesive tested works as a barrier, not allowing the migration of bacteria into the internal environment of the implant / prosthetic component assembly.

Resumo: Um aspecto crítico que afeta o sucesso ou falha de um implante é a maneira pela qual as tensões são transferidas do implante ao tecido ósseo. A sobrecarga na prótese dentária pode levar a perda da osseointegração, dessa forma, é aconselhável evitar altas concentrações de tensões no osso de suporte, do ponto de vista clínico. Entretanto, o estresse mecânico pode ter consequências positivas ou negativas no tecido ósseo, fatores esses dependentes de vários fatores associados que podem ser mecânicos ou biológicos. Portanto, o propósito do presente estudo foi analisar a influência da qualidade óssea na distribuição das tensões em próteses unitárias implantossuportadas com diferentes tipos de conexão protética, pelo método dos elementos finitos tridimensionais. Para isso, foram confeccionados doze modelos tridimensionais com o auxílio dos programas de modelagem gráfica SolidWorks 2010 e Rhinoceros 4.0, além do programa InVesalius.

Abstract: A critical issue that affects the success or failure of an implant is the manner in which the stresses are transferred from the implant to bone tissue. The overload can lead the dental implant to loss of osseointegration, thus it is advisable to avoid high stress concentrations in bone support, according to the clinical point of view. However, mechanical stress can bring positive or negative consequences in the bone tissue and these factors depend on association with mechanical or biological factors. Therefore, the purpose of this study was to analyze the influence of bone quality on stress distribution in implant-prosthesis unit with different types of prosthetic connection, by the three-dimensional finite element method. For this, twelve three-dimensional models were made with the aid of SolidWorks 2010 and Rhinoceros 4.0, graphical modeling software, besides the InVesalius. Each model was composed of a block with different bone qualities (Type I, II, III and IV), an implant (4.0 x 10 mm) with different type of prosthetic connection (Hexagon external, internal and Morse taper) and metal ceramic crown. After generation of geometries, the models were imported into FEMAP 10.2, the pre and post-processing finite element software, where it was generated finite element meshes, boundary and loading conditions. The 200N load was applied axially and 100N obliquely on the occlusal surface of crowns. This total load was divided among the cusps (four points for the axial load and two points for the oblique load on the lingual cusps). Then, the analysis was generated in the FEMAP 10.2 and exported to the NeiNastran version 9.2 software for calculation in finite element analysis, running on a workstation. The results were imported back to the FEMAP 10.2 for viewing and post-processing maps of von Mises stress and... (Complete abstract click electronic access below)

O objetivo deste estudo foi avaliar clínica e radiograficamente implantes curtos com 5 e 6 mm de comprimento (Titamax WS Neodent/ Curitiba-Brasil) unitários instalados em região posterior de mandíbula e maxila com pouca altura óssea. Foram instalados 10 implantes em 8 pacientes devidamente selecionados a partir de critérios de inclusão pré-determinados. Os mesmos receberam carregamento protético somente após o tempo convencional de espera para a osseointegração. Seis implantes foram instalados em mandíbula e 4 implantes em maxila. Tomadas radiográficas foram realizadas para avaliação das perdas ósseas verticais e horizontais nos tempos T0 (Instalação cirúrgica), T1 (Reabertura), T2 (Instalação protética) e T3 (Acompanhamento de 6 meses). Foram avaliados parâmetros biológicos como, sangramento gengival, índice de mucosa ceratinizada, índice de placa e índice de inflamação gengival. Também foram avaliados parâmetros protéticos como proporção coroa-implante e distância mesiodistal. Apenas um implante (Titamax WS Cortical 5.0x6.0) foi perdido ainda no período de osseointegração portanto o índice de sucesso foi de 90% no período avaliado. A alteração do nível ósseo foi analisada em três períodos diferentes, da instalação cirúrgica à cirurgia de reabertura (período 1), da reabertura à instalação protética (Período 2) e da instalação protética ao controle de seis meses (Período 3). Avaliando-se a perda óssea vertical nos três períodos separadamente foram encontrados valores muito semelhantes, inclusive iguais estatisticamente (ANOVA, p<0,05). O valor de perda óssea no período 1 foi de 0,32mm; no período 2 foi de 0,22mm e no período 3 foi de 0,29mm. Isso significa que os procedimentos cirúrgicos foram igualmente causadores de perda óssea marginal mesmo tomando-se alguns cuidados na execução destas etapas. A média de perda óssea vertical e horizontal no período total de acompanhamento foi de 0,87 ±0,46 e 0,24± 0,34 respectivamente. Estes valores foram considerados dentro do intervalo de perda óssea esperado. A boa condição de saúde gengival e higiene oral descartaram a possibilidade de associação entre os índices periodontais e a perda óssea periimplantar. O teste estatístico de Regressão Linear (p<0,05) mostrou não haver relação de causa/efeito entre perda óssea e os parâmetros protéticos, apesar de elevada proporção coroa/implantes (média 1,88). Com base nos resultados encontrados neste trabalho, concluiu-se que os implantes curtos, mesmo os de comprimento 5 e 6mm, devem ser considerados como uma importante alternativa de tratamento para casos unitários. Sugere-se porém, um maior tempo clínico de acompanhamento para que seja possível traçar um perfil do comportamento destes implantes a longo prazo.The aim of this study was to evaluate clinically and radiographically short unit implants with 5 and 6 mm in length (Titamax WS - Neodent / Curitiba, Brazil) installed in the posterior mandible and maxilla with little bone height. Ten implants were installed in eight carefully selected patients from inclusion criteria pre-determined. They received prosthetic loading only after the conventional time waiting for the osseointegration. Six implants were placed in the mandible and four implants in the maxilla. Radiographs were performed to evaluate the vertical and horizontal bone loss in T0 (surgery installation), T1 (uncovering), T2 (prosthetic installation) and T3 (follow-up of 6 months). Biological parameters were evaluated such as gingival bleeding index, keratinized mucosa amount, plaque index and gingival inflammation index. Prosthetic parameters were also evaluated as crown-implant ratio and mesiodistal distance. Only one implant (Titamax WS Cortical 5.0x6.0) was lost, it occurred during the healing fase. Therefore the success rate was 90% in the period. Bone level change was analyzed in three different periods, from surgical installation to uncovering surgery (1st period), from uncovering to prosthetic installation (2nd Period) and from prosthetic installation prosthetic to six months control (3rd Period ). Vertical bone loss values were very similar when evaluated in the three periods separately, even the same statistically (ANOVA, p <0.05). The amount of bone loss in 1st period was 0.32 mm in the 2nd period was 0.22 mm and in the 3rd period was 0.29 mm. This means that surgical procedures were also cause marginal bone loss even taking some care in implementing these steps. The average vertical and horizontal bone loss in the total period of observation was 0.87 ± 0.46 and 0.24 ± 0.34 respectively. These values were considered within the range of bone loss expected. The gingival good condition of health and oral hygiene ruled out the possibility of an association between periodontal indices and bone loss. Statistical analysis of linear regression (p <0.05) showed no cause and effect relationship between bone loss and prosthetic parameters, despite the high crown / implant ratio (average 1.88). Based on the findings of this study, it was concluded that short implants, even the 5 and 6 mm in length, should be considered as an important alternative treatment for single crows. It is suggested a longer clinical follow-up to make it possible to trace a pattern of behavior of these implants over the long term.

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.

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.

Total joint arthroplasty (TJA) is implemented primarily for the relief of pain, and secondarily for achieving better function by increasing the joint’s strength and motion. In order to keep health costs low, it is desirable that the TJA achieves and maintains a long-term and secure fixation of the implanted components. Unfortunately, clinical follow-up shows that the prosthetic finger implant components have long-term complications including bone resorption, wear, loosening, and failure of the implant components. Although the mechanism of complications is not fully understood, it is well known that the wear and failure of prostheses are highly related to the mechanical forces or stresses of implant components. It is therefore desirable that reliable 3-D computational finite element analysis (FEA) models can be developed and used for the stress analysis of implants. In this study, the finger proximal interphalangeal (PIP) prosthetic components were analyzed using a nonlinear finite element method. Implant components under different joint flexion angles as well as different forces were studied. The stress distribution on the contact surface of the implant component was obtained. The developed FEA models can be used to examine the contact situations (contact stress, contact region, and stress distribution), which are critical to the wear and potential failure of the implant components. Based on FEA results, the design of the current finger PIP implants can be improved for optimum performance and a long-term fixation.

Full textAbstract:
Endosseous dental implants are used as prosthetic treatment alternatives for treating partial edentulism [1]. Excellent long term results and high success rates have been achieved using dental implants during the past decades. Further improvements in implant protocols will include immediate loading, patient specific implants, applications for patients with extreme bone loss and extreme biting habits such as bruxism. The implant designs available in the market vary in size, shape, materials and surface characteristics [2], and address some of these concerns. An important factor in the implant design is the load transfer from the implant to bone during occlusal loading.[2,3] Load transfer starts along the bone-implant interface, and is affected by the loading type, material properties of the implant and prosthesis, implant geometry, surface structure, quality and quantity of the surrounding bone, and nature of the bone-implant interface [4]. While many studies using the finite element method (FEM) have been carried out [2–5], a systematic investigation of the load transfer at the bone implant interface, and the effects of various parameters that make the implant contour is lacking. The goal of this paper is to investigate one aspect of this multivariable problem, namely the effect of external implant threads on the load transfer along the bone-implant interface.

ICDs have the potential to cause physical discomfort for the patient and are typically implanted on top of the pectoral muscle and under subcutaneous tissue. High skin pressures and skin strains in the implant site, or pocket, have been theorized to be an indicator of discomfort, or in extreme cases, skin erosion. A reduction in skin pressures can be assumed to be consistent with an increase in overall patient comfort for subcutaneous implants, ref [1, 2, 3, 4, and 5]. Pocket size is governed by each physician’s implant technique and overall device shape.

Full textAbstract:
Total hip arthroplasty (THA) is an increasingly common procedure that replaces all or part of the hip joint. The average age of patients is decreasing, which in turn increases the need for more durable implants. Revisions in hip implants are frequently caused by three primary issues: femoral loading, poor fixation, and stress shielding. First, as the age of hip implant patients decreases, the hip implants are seeing increased loading, beyond what they were traditionally designed for. Second, traditional implants may have roughened surfaces but are not fully porous which would allow bone to grow in and through the implant. Third, traditional implants are too stiff, causing more load to be carried by the implant and shielding the bone from stress. Ultimately this stress shielding leads to bone resorption and implant loosening. Additive manufacturing (AM) presents a unique opportunity for enhanced performance by allowing for personalized medicine and increased functionality through geometrically complex parts. Much research has been devoted to how AM can be used to improve surgical implants through lattice structures. To date, the authors have found no studies that have performed a complete 3D lattice structure optimization in patient specific anatomy. This paper discusses the general design of an AM hip implant that is personalized for patient specific anatomy and proposes a workflow for optimizing a lattice structure within the implant. Using this design workflow, several lattice structured AM hip implants of various unit cell types are optimized. A solid hip implant is compared against the optimized hip implants. It appears the AM hip implant with a tetra lattice outperforms the other implant by reducing stiffness and allowing for greater bone ingrowth. Ultimately it was found that AM software still has many limitations associated with attempting complex optimizations with multiple materials in patient specific anatomy. Though software limitations prevented a full 3D optimization in patient specific anatomy, the challenges associated such an approach and limitations of the current software are discussed.

Full textAbstract:
Abstract Today’s technology of hip prosthesis implants, where the implant stem is fixed to the internal surface of the femur by bonding, bone growth or press fit, results in “stress shielding” of that portion of the implanted femur. Subsequent bone atrophy often requires remedial work and/or replacement of the hip prosthesis. A new design is presented in which the manner of the load transfer from the prosthesis to the bone greatly reduces stress shielding. The reduction of the stress shielding is so dramatic that a once-in-a-lifetime installation, without remedial work is a strong possibility.

Full textAbstract:
Modern design and manufacturing engineering technologies have greatly improved the way in which modern craniofacial implants are designed and fabricated. However, few efforts have been made in order to optimize their design. While the weight of polymer-based implants (e.g. PMMA implants) may not affect the patient’s comfort, the higher weight of metal-based implants (e.g. titanium implants), could greatly affect the patient’s comfort, causing in some cases nuisances and imbalance problems. Thus, the optimization of the implant becomes relevant in order to guarantee its structural stiffness but with a reduced weight. In this paper, the design and structural optimization of customized craniofacial implants based on the use of modern engineering technologies is presented. The aim is to introduce an engineering methodology for the design and optimization of customized craniofacial implants. The methodology starts from the patient’s medical images, obtained from a computerized tomography (CT), which are processed to reconstruct the digital 3D model. Next, the geometrical design of the implant is carried out in a computer aided design (CAD) system using the patient’s 3D model. Then, the structural analysis of the implant is performed using the Finite Element Method (FEM) and considering a quasi-static load. The topology optimization of the implant is made using the Solid Isotropic Material Penalization (SIMP) method. Finally, the optimized customized implant is fabricated in an additive manufacturing (AM) system. A case study of a craniofacial implant is presented and the results reveal that the proposed methodology is an effective approach to design and optimize craniofacial implants.

Full textAbstract:
The TMJ is a bilateral joint of the jaw that functions as a single entity during normal masticatory activities, speaking, yawning and swallowing. TMJ replacement has been indicated in cases of joint trauma, advanced degenerative disease, tumors, developmental anomalies and ankylosis of the joint following injury. Alloplastic replacement of the TMJ (an artificial replacement in the form of a TMJ condylar implant with a glenoid fossa component that articulates with the undersurface of the skull on the temporal bone) renders the anatomical space devoid of the natural mandibular condyle (Fig. 1). Compared to hip and knee prostheses, TMJ implants have not been studied in detail. The goals of this study were to quantify the stress distribution in a commercially available TMJ implant (TMJ Implants, Inc, CO), bone and implant-bone interface, to compare the stresses and strains with different bone conditions, and to compare the stresses and strains with different implant materials using a finite element software package.

"Effect of Varying Diameter of Dental Implants During Placements in Compromised Bony Ridges at Different Insertion Torques: A Finite Element Study." In ASME 2014 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2014. http://dx.doi.org/10.1115/imece2014-38388.
Full textAbstract:
The life of dental implant depends on various parameters such as insertion torque, implant diameter and cortical and cancellous bones thickness. The thickness of the cortical and cancellous bones varies from patient to patient and for each thickness, the corresponding studies are required to determine the favorable implant loading. In this study, stress analysis on various dental implant fixtures inserted in compromised bony ridges is performed using three dimensional finite element analyses. Initially, the modeling and analysis of previously analyzed structure is done to validate the solution procedure. After successful validation, three dimensional linear elastic analysis of bone implant bone assembly is performed. The implant material is treated as isotropic whereas the bone materials are taken as anisotropic materials. The parametric study finds the effect of insertion torque and variation of implant diameter on stress induced in the compromised bony ridge. Further, the implant bone assembly was analyzed using various cortical bone thicknesses. It has been observed that the increase in torque results in increased stress and deformation in the bone. With increasing bone thickness, the similar variation of torque produces less stress and deformation in dental implants. The study is helpful in prediction of favorable implant loading and implants diameters for compromised bony ridges. The study provides useful knowledge in improving the performance and life of dental implants.

Full textAbstract:
Abstract Transcortical implants have been used by numerous investigators to evaluate the response of cortical bone to various implant materials. The experimental model involves drilling holes through the cortex of a long bone of the experimental animal and then placing cylindrical implants or “plugs” of the test material in the drilled holes. The implants are retrieved after a predetermined period of implantation, and the bone/implant interface is assessed either mechanically, using the push-out test, or histologically to determine the response of bone to the material. Conclusions are then drawn as to the suitability of the material for implant applications. However, different researchers have reported a wide range of results from experiments designed to measure the response to apparently similar implant materials (Black, 1989).

Primary stability with the osseodensification drilling technique for dental implants in low density bone in humans: a systematic review.

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.

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.

Full textAbstract:
After five years of national programmatic use of Norplant® contraceptive implants, in 1992 the National Population and Family Planning Board (BKKBN) plans to implement a follow-up Use-Dynamics Study of implant users in West Java and West Sumatra Provinces, Indonesia. A Diagnostic Study was implemented in 1991 to prepare for that study prior to final approval, and to get some early insights into implant program operations in advance of final results from the main study. This report is a summary of findings from the Diagnostic Study. The Diagnostic Study had two broad objectives: to obtain information to guide development of the larger Use-Dynamics Study, and to supplement existing information on implant service delivery with a field-based observation study to help BKKBN make necessary decisions for its implant program. The Diagnostic Study helped in sharpening the original questionnaire draft, which has been appropriately revised.
