Abstract
Purpose: To evaluate the accuracy of osteotomy preparation and implant placement for 3 pilot-guided (PG) concepts, namely, a surgical template with a metal sleeve (MS), a surgical template with an in-built nonmetal sleeve (NMS), and a surgical template with an in-built nonmetal sleeve for round bur indentation (RB).
Methods: Surgical models with missing maxillary molars were studied. The MS templates were designed to accept metal sleeves, while the NMS and RB templates were designed with in-built nonmetal sleeves. Ten templates were tested per group (n = 10). After each step (pilot drilling, 2nd drilling, 3rd drilling, profiling, and implant placement), the surgical model was scanned and compared against the planning model to determine maximum horizontal deviation (MHD) and maximum angle deviation (MAD).
Results: The MS and NMS templates exhibited a similar increase in MHD with successive drilling steps. The MAD for the pilot drilling step was significantly lower for MS than for the other groups. However, the differences among groups for MHD and MAD diminished in later steps. All templates had an MHD of 1.0 mm or less and an MAD less than 8°.
Conclusion: The investigated PG implant placement concepts resulted in similar deviations in the placed implants.
目的:评价导导式(PG)三种术式的截骨准备和种植体放置的准确性，即金属套筒手术模板(MS)、内置非金属套筒手术模板(NMS)和圆形bur压痕内置非金属套筒手术模板(RB)。方法:对上颌磨牙缺失的手术模型进行研究。MS模板设计为可接受金属套筒，NMS和RB模板设计为内置非金属套筒。每组测试10个模板(n = 10)。在每个步骤(预钻孔、第二钻孔、第三钻孔、轮廓和植入物)完成后，对手术模型进行扫描，并与计划模型进行比较，以确定最大水平偏差(MHD)和最大角度偏差(MAD)。结果:MS和NMS模板的MHD随钻孔步骤的增加而增加。MS组先导钻井步骤的MAD显著低于其他组。然而，MHD和MAD组间的差异在随后的步骤中逐渐减小。所有模板的MHD小于等于1.0 mm, MAD小于8°。结论:所研究的PG种植体放置概念在放置种植体时产生了相似的偏差。
