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

**Official Title:** Accuracy of Fully Guided Dental Implant Placement: A Comparative Study of Experienced vs. Novice Clinicians Using Unilateral Tooth Supported, Bilateral Tooth Supported, and Soft Tissue Supported Guides

**NCT ID:** [NCT07112664](https://clinicaltrials.gov/study/NCT07112664)

## Key Facts

- **Status:** ACTIVE_NOT_RECRUITING
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 54
- **Lead Sponsor:** Abdelrahman Khalaf Eldabe
- **Conditions:** Accuracy of Fully Guided Dental Implant Placement Based on Clinician Experience and Surgical Guide Support Type
- **Start Date:** 2025-05-01
- **Completion Date:** 2025-12-15
- **CT.gov Last Update:** 2025-12-23

## 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

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
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

## Arms

- **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.
- **Novice Clinician - Unilateral Tooth-Supported Guide** (EXPERIMENTAL) — Participants receive fully guided dental implant placement using a unilateral tooth-supported surgical guide, performed by a novice clinician.
- **Novice Clinician - Mucosa-Supported Guide** (EXPERIMENTAL) — Participants receive fully guided dental implant placement using a mucosa-supported surgical guide. The procedure is carried out by a novice clinician under standard protocol.

## Interventions

- **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.

## Primary Outcomes

- **Angular Deviation** _(time frame: 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 Outcomes

- **Coronal Global Deviation (CGD)** _(time frame: Immediately postoperative)_
- **Apical Global Deviation (AGD)** _(time frame: Immediately postoperative)_
- **Depth Deviation** _(time frame: Immediately postoperative)_
