To compare and contrast the accuracy of piezoelectric ultrasonic insert (PUI) and trephine bur (TB) osteotomy site preparation techniques for apical location. (1) Material and methods: A total of 138 osteotomy site preparations were randomly distributed into one of two study groups. Group A: TB technique ( = 69) and B: PUI technique ( = 69). A preoperative cone-beam computed tomography scan and an intraoral scan were performed and uploaded to implant-planning software to plan the virtual osteotomy site preparations for apical location. Subsequently, the osteotomy site preparations were performed in the experimental models with both osteotomy site preparation techniques and a postoperative CBCT scan was performed and uploaded into the implant-planning software and matched with the virtually planned osteotomy site preparations to measure the deviation angle and horizontal deviation as captured at the coronal entry point and apical end-point between osteotomy site preparations using Student's -test statistical analysis. (2) Results: The paired -test found statistically significant differences at the coronal entry-point deviations ( = 0.0104) and apical end-point deviations ( = 0.0104) between the TB and PUI study groups; however, no statistically significant differences were found in the angular deviations ( = 0.309) between the trephine bur and piezoelectric ultrasonic insert study groups. (3) Conclusions: The results showed that the TB is more accurate than the PUI for apical location.
比较和对比压电超声植入物（PUI）和环钻（TB）截骨部位制备技术在根尖定位方面的准确性。（1）材料与方法：总共138次截骨部位制备被随机分配到两个研究组之一。A组：TB技术（n = 69）和B组：PUI技术（n = 69）。进行术前锥形束计算机断层扫描和口内扫描，并上传至种植计划软件，以规划根尖定位的虚拟截骨部位制备。随后，使用两种截骨部位制备技术在实验模型中进行截骨部位制备，并进行术后CBCT扫描，上传至种植计划软件，并与虚拟规划的截骨部位制备进行匹配，以测量截骨部位制备在冠状入口点和根尖终点处的偏差角度和水平偏差，采用学生t检验统计分析。（2）结果：配对t检验发现，TB和PUI研究组在冠状入口点偏差（P = 0.0104）和根尖终点偏差（P = 0.0104）方面存在统计学显著差异；然而，环钻和压电超声植入物研究组在角度偏差（P = 0.309）方面未发现统计学显著差异。（3）结论：结果表明，在根尖定位方面，TB比PUI更准确。
