Guided dental implant placement vs freehand placement
Official title: Surgical Guide Versus Freehand Dental Implants Placement
Run by Sana'a University · NCT07909278 · Data updated 2026-11-12
This study tests whether using a surgical guide makes dental implant placement more accurate than the traditional freehand method in adults needing implants.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 needing one or more dental implants, in good health with excellent oral hygiene and the ability to attend follow-up visits.
✕Probably not a fit
Patients with poor oral hygiene, systemic conditions affecting healing, heavy smoking, or those requiring extensive bone grafting may not benefit.

What this trial studies
This randomized trial compares two approaches for dental implant placement: a static computer-assisted surgical guide versus conventional freehand placement. The primary outcome is how closely the actual implant positions match the preoperative plan, measured by 3D image superimposition after surgery. Participants are partially edentulous adults with good health and no conditions that impair healing, who require one or more implants. Implants are placed using either guided surgery or freehand techniques, and results are analyzed to determine if the surgical guide improves positional accuracy. The study is conducted at the Faculty of Dentistry, Sana’a University, under the leadership of the lead sponsor Khadyjah Ali Ali Alrassas.
Why it matters
Potential benefit: If successful, guided implant placement could improve accuracy and potentially reduce complications and need for adjustments.
How similar studies have gone: Previous studies in guided implant techniques have shown improved accuracy in some settings, supporting feasibility but with variability across methods.

Inclusion Criteria: * Partially edentulous patients in need of one or more dental implants. * Good overall health with no systemic conditions that impair healing. * Absence of systemic diseases. * Excellent oral hygiene. * Patients over 18 years of age. * Cooperative patients motivated to attend follow-up and maintenance visits. * Patients who agree to sign an informed consent form. Exclusion Criteria: * Systemic conditions or pharmacological therapies that would render the intervention contraindicated (e.g., uncontrolled diabetes, immunocompromised states, treatment with oral or parenteral bisphosphonates, or osteoporosis). * Poor oral hygiene. * Heavy smokers (\>10 cigarettes/day). * Pregnant patients, patients under 18 years of age, and elderly patients over 65 years of age. * Patients who are uncooperative or unable to attend scheduled follow-up visits. * Patients requiring extensive bone grafting. * Limited mouth opening.
