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.

Detailed 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.

Conditions

• Tooth Extraction Status Nos
• Bone Loss
• Bone Resorption

Interventions

Type	Name	Description
PROCEDURE	"Pontic-shield" technique	A 1mm thick fragment of the vestibular aspect of the root will remain after extraction (partial extraction)
PROCEDURE	Alveolar ridge preservation	Particulate deproteinized bovine bone and porcine collagen membrane will be placed after tooth extraction
