摘  要:目的:通过测量ITI和Osstem-SS种植系统的稳定系数(ISQ),评价这两种种植体的骨结合情况,为临床确定其上部结构修复时机提供依据。方法:93例牙列缺损患者共植入179颗种植体,根据患者种植区骨量情况分为两组,其中A组为种植区骨量良好,不需骨增量手术病例(62例);B组为种植区骨量不足,需进行骨增量手术病例(31例)。A组共植入125颗种植体,其中ITI种植系统64颗,OSSTEM-SS种植系统61颗;B组共植入54颗种植体,其中ITI种植系统28颗,OSSTEM-SS种植系统26颗。术后即刻及第4、6、8、12、16、24周分别测量各时期种植体稳定系数(ISQ),并同期进行临床和影像学检查。结果:A组中ITI种植系统术后8周ISQ值平均(74.17±1.85),进行负重;OSSTEM-SS种植系统术后12周ISQ值平均(72.00±2.59),进行负重。B组中ITI种植系统术后16周ISQ值平均(65.09±3.42),进行负重;OSSTEM-SS种植系统术后24周ISQ值平均(62.09±6.16),进行负重。负重后临床随访3-24个月所有病例均成功,咀嚼功能良好,患者满意。结论:种植体稳定系数(ISQ)能反应种植体骨结合情况,可以协助医生选择种植后合适的冠修复时机。Objective: To investigate the osseointegration condition of ITI and Osstem-SS implants by measuring the implant stability quotient(ISQ) so as to provide guidance for proper restoration time.Method: Ninety-three patients were selected as subjects.179 implants were implanted.According to bone quantity of edentulous area,all the subjects were divided into two groups.62 patients with sufficient bone quantity were in group A,while 31 patients with insufficient bone quantity who needed bone-added surgery were in group B.125 implants were implanted in group A,including 64 ITI implants and 61 Osstem-SS implants.54 implants were implanted in group B,including 28 ITI implants and 26 Osstem-SS implants.Implant stability quotient(ISQ) was measured immediately after surgery as well as at the 4,6,8,12,16,24 weeks after surgery.Clinical and imaging examination was taken at the same time.Results: In group A,final restoration of ITI implants was completed 8 weeks after surgery when the ISQ was 74.17±1.85,while 12 weeks with ISQ was 72.00±2.59 for Osstem-SS implants.In group B,16 weeks with ISQ was 65.09±3.42 for ITI implants and 24 weeks with ISQ was 62.09±6.16 for Osstem-SS implants.In the following period of 3 to 24 months after restoration,no failure case was observed.Conclusion: Implant stability quotient(ISQ) can represent the osseointegration condition of implants,which will help to choose the proper restoration time.
