摘　　要：目的:建立一种新的数字化配准法,测量种植体植入精度,并与传统锥体束CT(CBCT)进行对比。方法:根据纳入和排除标准,纳入24例患者的36颗种植体作为研究对象,分别采用传统CBCT法和数字化配准法对种植体植入精度进行测量分析。测量参数为种植体颈部偏差(d1)、根尖部偏差(d2)和角度偏差(α)。采用SPSS 19.0软件包对数据进行统计学分析。结果:传统CBCT法测量精度为种植体颈部(0.88±0.64) mm,种植体根尖部(1.07±0.85) mm,角度(4.74±2.35)°;数字化配准法测量的精度为种植体颈部(0.86±0.67) mm,种植体根尖部(1.12±0.88) mm,角度(4.56±2.66)°;两者之间无统计学差异(P>0.05)。结论:数字化配准法的测量精度与传统CBCT无显著差异,可用于临床实践。PURPOSE:The aim of this study was to introduce a new method to evaluate the clinical accuracy of implant position.The results were compared to traditional cone beam CT(CBCT)method.METHODS:A total of 36 implants from 24 patients with sufficient bone volume were enrolled into the study.CBCT method and digital registration method were compared to evaluate the accuracy of implant position.The measurement parameters were defined as deviations between ideal and postsurgical implant position at occlusal point(d1),apical point(d2)and axis(α).The deviations between two methods were analyzed with SPSS 19.0 software package.RESULTS:The deviations between ideal and postsurgical implant position using CBCT were(0.88±0.64)mm for occlusal point,(1.07±0.85)mm for apical point and(4.74±2.35)°for angle.In digital registration method,the deviations were(0.86±0.67)mm for occlusal point,(1.12±0.88)mm for apical point and(4.56±2.66)°for angle.No significant difference(P>0.05)was found between the two methods.CONCLUSIONS:There was no significant difference between the two methods in evaluating the clinical accuracy of implant position.Digital registration method could be accepted in clinical application.
