Randomized Clinical Study Comparing Two Guided Surgery Techniques for Free-end Implant Placement

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 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.

Exclusion criteria

  • 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.

Treatment and study plan

Dental implant placement

Procedure

Placement of two dental implants in the jaw.

Primary outcomes

  1. Three-dimensional implant position deviations (measured by intraoral scan and planning software)

    Time frame: 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 outcomes

  1. Three-dimensional implant position deviations (measured by CBCT and planning software)

    Time frame: 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.
