Rate of pull-out strength gain of dual-etched titanium implants: a comparative study in rabbits.

摘要: The purpose of this study was to investigate the rate pull-out strength gain an etched titanium implant surface. Rabbit tibiae were used compare machined and proprietary dual-etched implants. Two custom cylindric implants (3 mm in diameter 4 length) placed each right anteromedial tibia 31 rabbits. At weeks 1, 2, 3, 4, 5, 8, 5 rabbits subjected failure shear loading a test. For testing, tibial segment mounted precision alignment jig, Instron test performed on implant. Beginning at week there statistically significant difference (P < .01) between There increase for while did not show during time interval. maintained significantly greater remainder study, with 3.2-fold mean 8 weeks, equivalent 6 months humans. 3 implant's exceeded that had achieved weeks. In short-term healing rabbit tibia, surface demonstrated more rapid than remained stronger throughout study.
