Evaluation of Accuracy in Fully Guided Dental Implant Surgery Using 3D-Printed Surgical Guides Without Metal Sleeves: A Split-Mouth In Vivo Study

What this Trial Is About

Researchers are evaluating the accuracy of fully guided dental implant surgery using 3D-printed surgical guides that do not have metal sleeves. This study focuses on adult patients who are partially or fully edentulous and require complete-arch rehabilitation with dental implants. The goal is to compare the planned implant positions with the actual positions after surgery, measuring linear and angular deviations to understand how well the surgery matches the virtual plan. The study uses a split-mouth design, where each participant receives two types of surgical guides with different drilling channel diameters: a standard diameter (4.85 mm) and a slightly reduced diameter (4.83 mm). These guides are digitally designed and fabricated with biocompatible resin using 3D printing technology. After virtual planning using cone-beam computed tomography and intraoral scans, implants are placed using these metal sleeve-free guides, and the accuracy of placement with each drilling channel size is compared. Participants will undergo implant placement using the assigned surgical guides, followed by postoperative intraoral and cone-beam CT scans with scan bodies to capture the final implant positions. Researchers will analyze the difference between planned and actual implant placement using three-dimensional software to measure deviations. This study includes statistical analysis of these differences and aims to assess whether reducing drilling channel diameter improves implant accuracy. The total study duration extends through the postoperative assessment immediately after implant placement.
