Brief Summary

The goal of this clinical trial is to learn how accurate fully guided dental implant placement is when performed by experienced versus novice clinicians. It will also study how different types of surgical guides affect the accuracy of implant placement. The main questions it aims to answer are: Does the clinician's level of experience affect how closely the dental implant matches the planned position? Does the type of surgical guide (tooth-supported or mucosa-supported) influence implant placement accuracy? Researchers will compare the implant accuracy across six groups based on clinician experience and guide type. Participants will: Undergo a fully guided dental implant procedure using a 3D-printed surgical guide Be treated by either an experienced or a novice clinician Receive follow-up scans to measure how accurately the implant was placed compared to the digital plan

Outcome Measures

Primary Outcomes (1)

Angular Deviation
The angular deviation is defined as the angle (in degrees) between the long axis of the virtually planned implant and the long axis of the actual placed implant. It reflects the angular accuracy of guided implant placement.
Immediately postoperative (within 1 day after implant placement)

Secondary Outcomes (3)

Coronal Global Deviation (CGD)
Immediately postoperative
Apical Global Deviation (AGD)
Immediately postoperative
Depth Deviation
Immediately postoperative

Study Arms (6)

Experienced Clinician - Bilateral Tooth-Supported Guide

EXPERIMENTAL

Experienced Clinician - Bilateral Tooth-Supported Guide Participants receive fully guided dental implant placement using a bilateral tooth-supported surgical guide. The procedure is performed by an experienced clinician with over 500 guided implant placements.
