Not Applicable

Recruiting

• Conditions: Dental Implant; Bone Resorption

• Registration Number: NCT06764654
• Lead Sponsor: Aula Dental Avanzada

Brief Summary

This is a randomized multicenter clinical study that compares two static guided surgery techniques in free-end partial edentulism.

The aim is to compare the accuracy obtained between dento-osseous supported and dento-mucosal supported surgical splints to place dental implants in posterior osseous ridges.

Primary Outcome Measures

Name	Time	Method
Three-dimensional implant position deviations (measured by intraoral scan and planning software)	From enrollment to the end of surgery	Three-dimensional deviations between the planned implant position and the actual postoperative implant position will be assessed. The deviations will be measured using an intraoral scanner (Medit i700®) and planning software (BlueSky Plan®). Units of measure: horizontal and vertical linear deviation (in millimeters), global deviation (in millimeters), and angular deviation (in degrees), evaluated at both implant entry and apex points.

Secondary Outcome Measures

Name	Time	Method
Three-dimensional implant position deviations (measured by CBCT and planning software)	From enrollment to the end of surgery	Three-dimensional deviations between the planned implant position and the actual postoperative implant position will be assessed. The deviations will be measured using cone-beam computed tomography (CBCT) and planning software (BlueSky Plan®). Units of measure: horizontal and vertical linear deviation (in millimeters), global deviation (in millimeters), and angular deviation (in degrees), evaluated at both implant entry and apex points.
