“…Over the last 30 years, clinical evidence has shown excellent long-term results for osseointegrated implants with success rate above 90% (1,2). However, this predictable treatment requires a dynamic equilibrium between mechanical and biological factors.…”

“…Thus, alternative implant systems with different connections have been launched to the market and their main claim is that the use of the new systems can avoid periimplant tissue inflammation. Conical interfaces, as Morse taper and locking taper systems, have shown a precise fit between implant and abutment (1,11,12), which could avoid bacterial penetration through the interface. In addition, these conical systems have the implant-abutment interface localized in the middle of the implant platform, different from external hexagon systems, whose interface is close to the alveolar bone (1,9).…”

Preload loss and bacterial penetration on different implant-abutment connection systems

Preload loss can favor the occurrence of implant-abutment interface misfit, and bacterial colonization at this interface may lead to implant failure. The aim of this study was to evaluate the preload loss and bacterial penetration through the implant-abutment interface of conical and external hexagon connection systems subjected to thermal cycling and mechanical fatigue (TM). Four different implant-abutment connection systems were evaluated (n=6): external hexagon with universal post, Morse taper with universal post, Morse taper with universal post through bolt, and locking taper with standard abutment. The assemblies (implant-abutment) were subjected to a thermal cycling regimen (1,000 cycles of 5°C and 55°C) and to mechanical fatigue (1.0 million cycles, 1.0 Hz, 120 N). The assemblies were immersed in Tryptic Soy + Yeast Extract broth containing Streptococcus sanguinis and incubated at 37°C and 10% CO 2 for 72 h. Detorque values were recorded. The bacterial penetration was assessed and the abutments were observed by scanning electron microscopy. The preload data were analyzed statistically by two-way ANOVA and Tukey's test at 5% significance level. All screw abutment systems showed significantly higher (p<0.05) detorque values when subjected to TM and all conical systems presented bacterial penetration. The results show no relationship between the preload loss and the bacterial penetration.

“…Por isso foi utilizado um implante com uma geometria mais favorável, nesse caso, o implante Cone Morse, que apresenta um papel relevante em preservação de tecido ósseo, uma vez que permite uma taxa menor de perda óssea quando comparado com outros modelos de implantes 9 , como, por exemplo, de hexágono externo. De fato, a literatura tem indicado diversos benefícios da utilização da geometria cone Morse, apresentando uma maior eficiência na preservação do tecido ósseo 15 e, melhor comportamento biomecânico 16 .…”

Objetivo: a utilização de métodos de regeneração tecidual tem sido amplamente empregada na Implantodontia em situações clínicas com deficiências ou limitações anatômicas que impossibilitam a instalação de implantes osseointegrados. A evolução no desenvolviUm dos fatores que ainda merece discussão está relacionado à deficiência de tecido ósseo vestíbulo--lingual. Nessas situações existe a possibilidade de as roscas dos implantes ficarem expostas ou existir reabsorção óssea após a instalação do implante 4 . Assim, a literatura propôs vários tratamentos para corrigir esta deficiência, como por exemplo, a utilização de biomateriais e membranas para recobrir a superfície do implante exposta [4][5][6] . É fato concebido que os biomateriais atrelados à utilização de uma membrana conseguem estimular a formação e/ou manutenção do tecido ósseo alveolar ao redor do implante 7 , existem relatos da utilização de hidroxiapatita enriquecida de magnésio, matriz óssea desmineralizada humana, osso mineral bovino desproteinizado 8 , entretanto ainda é um tema polêmico que merece discussão.
