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

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| Experienced Clinician - Unilateral Tooth-Supported Guide | Experimental | Experienced Clinician - Unilateral Tooth-Supported Guide Participants receive fully guided dental implant placement using a unilateral tooth-supported surgical guide. The procedure is conducted by an experienced clinician. |
|
| Experienced Clinician - Mucosa-Supported Guide | Experimental | Participants receive fully guided dental implant placement using a mucosa-supported surgical guide. The procedure is performed by an experienced clinician with extensive experience in guided surgery. |
|
| Novice Clinician - Bilateral Tooth-Supported Guide | Experimental | Participants receive fully guided dental implant placement using a bilateral tooth-supported surgical guide. The procedure is performed by a novice clinician with fewer than 20 guided implant cases and at least one year of general implant experience. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Fully Guided Dental Implant Placement Using Surgical Guide | Device | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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) |
| Measure | Description | Time Frame |
|---|---|---|
| Coronal Global Deviation (CGD) | The linear distance (in mm) between the apical center of the planned and placed implant. | Immediately postoperative |
| Apical Global Deviation (AGD) | The linear distance (in mm) between the apical center of the planned and placed implant. |
