简要总结
This randomized clinical trial aims to compare the accuracy of single-drill (pilot-guided) computer-guided implant surgery versus full-sequence computer-guided dental implant placement. The study evaluates clinical and radiographic outcomes, focusing on apical, angular, coronal, and depth linear deviations using post-operative cone-beam computed tomography (CBCT) superimposition.

研究组 & 干预措施
Full Sequence Computer Guidance
Patients undergo dental implant placement using full-sequence computer guidance, where implant site preparation and insertion are accomplished using all sequential drills and metal reducers with the surgical guide.
干预措施: Full-sequence computer-guided dental implant placement. (Procedure)
Single Drill / Pilot-Guided Computer Guidance
Patients undergo dental implant placement using first-drill (pilot-guided) computer guidance, where the initial pilot osteotomy is performed through the surgical guide, followed by removal of the guide and completion of the remaining sequential drilling and implant placement freehand.
干预措施: Single-drill computer-guided dental implant placement (Procedure)
结局指标
