"Pontic-shield" Technique in Alveolar Ridge Preservation

Status Recruiting

Clinical Trial Summary

Alveolar bone resorption after dental extraction frequently leads to situations in which long-term function and esthetic success of rehabilitations with dental implants is a challenge. "Pontic-shield" has been described as an alternative technique to maintain alveolar ridge after tooth extraction. The aim of this study is to analyze the effectiveness of "Pontic-shield" technique in alveolar ridge preservation comparing to fresh socket and ridge preservation using deproteinized bovine bone and a porcine collagen membrane.

Clinical Trial Description

A three-arm randomized clinical study will be conducted: - Group 1 (study group): Ridge preservation with "Pontic-shield" technique. - Group 2 (positive control): Ridge preservation with deproteinized bovine bone and porcine collagen membrane after tooth extraction. - Group 3 (negative control): Tooth extraction only (fresh socket). A cone-beam computed tomography will be performed prior to tooth extraction and 4 months postoperative. Radiographic changes between before and after intervention will be evaluated to asses the effectiveness of "Pontic-shield" technique. ;
