Osstell分析仪评估骨挤压术对种植体初期稳定性的影响

目的采用Osstell分析仪评估骨挤压术对ITI和31种植体初期稳定性的影响。方法选取上颌后牙Ⅳ类骨质的牙列缺损患者，所有患者行颌骨CBCT扫描，确定种植位点，植入Ⅲ和31种植体共23颗种植体（中5．0mm×10．0mm）。同时记录ISQ值，对结果进行双因素方差分析。结果骨挤压术较传统备洞技术所获得的种植体稳定性高（P〈0．05）；Ⅲ和3I两种系统的种植体稳定性间差异无统计学意义。结论在上颌后牙Ⅳ类骨区，应用Osstell分析仪可以定量分析种植体初期稳定性，与传统备洞技术相比，采用骨挤压术可获得较高的种植体初期稳定性。

The research of osteotome technique on the primary stability of dental implants using osstell mentor

Objective To evaluate the influence of osteotome technique on the initial implant stability of ITI and 31 implants by Osstell analyzer. Methods Patients with dentition defect of Lekholm ＆ Zarb classification type IV were enrolled in this study, all of which underwent CBCT scan to determine the implant site;And 23 ITI and 3I implants （qb5.0xLlO.O ram） were implanted.The implant stability quotient （ISQ） of each patient was recorded;And the results were analyzed by two-way ANOVA. Results The ISQ of implant by osteotome technique was significantly higher than that by conventional technique （P〈0.05）;No statistical difference was observed between ITI and 3I systems in their implant stability. Conclusion By using Osstell analyzer,it can quantitatively evaluate the initial implant stability in patients with dentition defect of Lekholm ＆ Zarb classification type IV ,compared with conventional technique, osteotome technique would result in a higher initial implant stability.
