Osstell ISQTM监测种植体稳定性的临床研究

摘要

目的：分析种植体初期稳定系数（ISQi）与植入扭矩值（ITv）在评估初期稳定性中的关系；分析不同初期稳定性种植体在骨愈合期种植体稳定系数（ISQ）的变化趋势。方法：选择牙缺失患者34例，共55枚种植体。应用Osstell ISQTM共振频率分析仪于种植体植入时测量ISQ和记录ITv，并于植入后4周、8周、12周监测ISQ变化。结果： ISQi与ITv存在强正相关性。低初期稳定性组种植体植入后ISQ呈持续上升过程，高初期稳定性组ISQ则呈先降后升趋势，4周降至最低点。结论： Osstell ISQTM能良好评价和监测种植体稳定性， ISQi与ITv均为评价种植体初期稳定性的客观指标，种植体稳定性的变化趋势与初期稳定性范围相关。%Objective: The purpose of the present study was to analyze the relationship between initial im-plant stability quotients (ISQi) and insertion torque value (ITv) on implant stability evaluatation, and discuss the change of implant stability quotients (ISQ) of different initial stability over the healing time. Methods: Thirty-four patients who needed one or more dental implants were collected in the research. A total of 55 implants were inserted. At the time of implant placement, each implant was tested for pri-mary stability by resonance frequency analysis (RFA) and insertion torque. RFA was performed again during examinations at 4, 8 and 12 weeks following surgery. Results: A strong, positive correlation was found between ISQi and ITv. In the lower initial stability group, the ISQ steadily increased throughout the healing period, whereas in the higher groups decreased in the first four weeks and then increased gently. Conclusions: Osstell ISQTM is a quite sensitive simple-used instrument to measure and evaluate the implant stability. ISQi and ITv are the favorable indices to evaluate the initial implant stability. ISQ change pattern is closely related to the primary stability.
