Pełny tekst źródłaA procura de reabilitações orais cada vez mais próximas dos dentes naturais contribuiu para a evolução das técnicas de reabilitação oral, nomeadamente na área da implantologia, onde atualmente são levantados vários paradigmas, entre os quais se encontra a discussão entre a utilização de próteses cimentadas versus as próteses aparafusadas. 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.

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.

Pełny tekst źródłaINTRODUCTION: 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)

Pełny tekst źródłaIntroduction: 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.

Pełny tekst źródłaCom o objetivo de prevenir o afrouxamento, parafusos do pilar com lubrificantes sólidos de superfície foram desenvolvidos e introduzidos no mercado. 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.

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.

Pełny tekst źródłaThe 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.

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)

Pełny tekst źródłaThe 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.
