An interventional study of Dental implant placement in Dental Implant and Bone Resorption, sponsored by Aula Dental Avanzada. Recruiting at 2 sites in Spain. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-09.
Sponsored by Aula Dental Avanzada · Not applicable, Interventional, and Treatment
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.
Sample size increased from 20 to 40 participants (80 implants) via non-substantial amendment, acknowledged by the CEI Hospital Universitario Sant Joan d'Alacant (April 2026). Randomization and masking procedures unchanged.
167 studies on the registry are indexed under Bone Resorption; 28 are open to participants now.
This study's planned enrollment of 40 is above the median of 24 across 146 interventional studies indexed under Bone Resorption.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Patients who will receive implant placement using a tooth supported surgical guide.
Procedure: Dental implant placement
Patients who will receive implant placement using a bone and tooth supported surgical guide.
Procedure: Dental implant placement
Placement of two dental implants in the jaw.
Three-dimensional implant position deviations (measured by intraoral scan and planning software)
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.
Time frame: From enrollment to the end of surgery
Three-dimensional implant position deviations (measured by CBCT and planning software)
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.
Time frame: From enrollment to the end of surgery

Started Jan 2025 (actual). Primary completion is estimated for Jan 2027, 24 months after the start.
Of 82 non-industry interventional studies with no phase under Bone Resorption, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 35. This study's planned 24 months is close to that.
Counting every sponsor, half of 83 studies reached it within 23 months; a quarter within 12 and three quarters within 35.
Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 9, 2026: primary completion Jan 2026 → Jan 2027 and completion Mar 2026 → Mar 2027.
