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.

Outcome Measures
Primary Outcomes (1)
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.
From enrollment to the end of surgery
Secondary Outcomes (1)
Three-dimensional implant position deviations (measured by CBCT and planning software)
From enrollment to the end of surgery
Study Arms (2)
Tooth supported guide
ACTIVE COMPARATORPatients who will receive implant placement using a tooth supported surgical guide.
Bone and tooth supported guide
EXPERIMENTALPatients who will receive implant placement using a bone and tooth supported surgical guide.
Interventions
Placement of two dental implants in the jaw.
Eligibility Criteria
You may qualify if:
- Patients who present to one of the two participating clinics with a posterior edentulous area starting from the second premolar.
- Patients in whom the placement of dental implants is not contraindicated.
You may not qualify if:
- Patients with hypersensitivities or allergies that contraindicate the intervention.
- Presence of orofacial neurological symptoms.
- Patients treated with bisphosphonates.
- Pregnant or breastfeeding women, or women undergoing contraceptive treatment.
- Signs of infection in the surgical area.
- Need for unconventional surgical procedures (e.g., split crest, vertical regeneration, block graft).
- Lack of patient cooperation.
