About this study
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
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:
Read more
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

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fully Guided Dental Implant Placement Using Surgical GuideDevice
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 group | Role | What they receive |
|---|---|---|
| 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. Receives: Device: Fully Guided Dental Implant Placement Using Surgical Guide |

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Immediately postoperative (within 1 day after implant placement)
Secondary outcomes (3)
Coronal Global Deviation (CGD)
The linear distance (in mm) between the apical center of the planned and placed implant.
Measured: Immediately postoperative
Apical Global Deviation (AGD)
The linear distance (in mm) between the apical center of the planned and placed implant.
Measured: Immediately postoperative
Depth Deviation
The difference in depth (in mm) between the planned and actual implant positions along the implant's central axis.
Measured: Immediately postoperative

A study testing Fully Guided Dental Implant Placement Using Surgical Guide in people with Accuracy of Fully Guided Dental Implant Placement Based on Clinician Experience and Surgical Guide Support Type, run by Abdelrahman Khalaf Eldabe at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 23 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Angular Deviation (time frame: Immediately postoperative (within 1 day after implant placement)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07112664, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Dec 2025.
