A study on the resistance at bone-implant interface during implant insertion in a cadaver goat jaw model

[摘要] Background: The aim of the study is to determine the resistance at bone-implant interface during insertion of dental implant. Materials and Methods: Freshly procured cadaver goat mandibles were collected from slaughterhouses. Four dental implants of two different diameters were inserted into osteotomized sites of the goat mandibles. The gradual changes in resonance frequency (RF) were recorded in RF analyzer for the five consecutive turns of implant insertion. Results and Observations: RF was found to be positively correlated with diameter of dental implants. Conclusion: RF analysis can be used to determine the type of resistance the implant faces during insertion and the kind of bone density through which it passes. It gives a forecast of expected initial stability.
