Abstract

Abstract: Objective: To investigate the effect of different bone condensation methods on the stability of implant and crestal region bone loss, so as to improve the design of condensation protocol. Methods: In this study, three different groups were designed: Undersized Group (Control), Modified Condensation Group (Test A), and Normal Condensation Group (Test B). Different operation protocols were used and the implants with same diameter were inserted into healed maxillary extraction sites of CD1 mice. The mice were killed right after the operation or 3 or 21days after the implant insertion, and the lateral stability testing and histological examinations were performed. Results: Accumulation of TRAP⁺ cell and crestal region bone loss were observed in Test B Group, and the secondary stability of Test B Group was significantly lower than that of Test A Group. Conclusion: Optimizing the condensation protocol is beneficial to reducing occurrence probability of bone resorption after condensation.
