Accuracy of Immediate Implant Placement using three surgical approaches

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized trial compares three methods for placing immediate dental implants in the lower jaw after extracting a molar or retaining root: freehand surgery, conventional tooth-supported static computer-guided surgery, and a tooth- and socket-supported static guide. All participants undergo preoperative CT and intraoral scans to plan the ideal implant position, then are randomly assigned to one of the techniques. The main outcome is 3D accuracy, measured by deviations in coronal, apical, angular, and depth positions between planned and actual implant locations using postoperative imaging. The study focuses on adults aged 20–56 with ASA I–II, good oral hygiene, and a Class I extraction socket eligible for a single-unit screw-retained crown.
