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
Interventions
DEVICEFully 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.

Inclusion criteria
* Age 18 years or older * Clinical situation suitable for dental implant placement as judged by the examining physician or principal investigator * Adequate soft and hard tissue conditions for implant placement * Adequate occlusion in the implant area * Sufficient bone volume to place the implant without bone augmentation (i.e., at least 2 mm of bone circumferentially around the implant site based on preoperative CBCT)
Exclusion criteria
* Major systemic diseases (e.g., uncontrolled diabetes, immunosuppressive conditions) * Untreated or uncontrolled dental caries * Active periodontal disease * Requirement for bone augmentation or sinus lift in the implant area * Current pregnancy * Current smoker (defined as \>10 cigarettes per day) * Noncompliance or inability to follow study protocols * Known allergies to materials used in the implant system or medications administered
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| Coronal Global Deviation (CGD) | Immediately postoperative | The linear distance (in mm) between the apical center of the planned and placed implant. |
| Apical Global Deviation (AGD) | Immediately postoperative | The linear distance (in mm) between the apical center of the planned and placed implant. |
| Depth Deviation | Immediately postoperative | The difference in depth (in mm) between the planned and actual implant positions along the implant's central axis. |
