Active, not recruiting

• Conditions: Accuracy of Fully Guided Dental Implant Placement Based on Clinician Experience and Surgical Guide Support Type

• Registration Number: NCT07112664
• Lead Sponsor: Abdelrahman Khalaf Eldabe

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

• Active periodontal disease
• Requirement for bone augmentation or sinus lift in the implant area
• Current pregnancy

Primary Outcome Measures

Name	Time	Method
Angular Deviation	Immediately postoperative (within 1 day after implant placement)	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.

Secondary Outcome Measures

Name	Time	Method
Depth Deviation	Immediately postoperative	The difference in depth (in mm) between the planned and actual implant positions along the implant's central axis.
Apical Global Deviation (AGD)	Immediately postoperative	The linear distance (in mm) between the apical center of the planned and placed implant.
Coronal Global Deviation (CGD)	Immediately postoperative	The linear distance (in mm) between the apical center of the planned and placed implant.
