Accuracy of Fully Guided Dental Implant Placement by Experienced and Novice Clinicians Using Different Surgical Guides

Condition(s) studied

Investigational drug(s) / intervention(s)

Fully Guided Dental Implant Placement Using Surgical Guide: All participants will undergo fully guided dental implant placement using a 3D-printed surgical guide (tooth-supported or mucosa-supported). The surgical guide is designed and fabricated based on preoperative CBCT and intraoral scan data. Implant site preparation and fixture insertion are performed entirely through the guide using manufacturer-specific guided surgery kits.

Study 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

Eligibility

Primary outcome measure(s)

• 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.
