Clinical Trial Summary

The goal of this clinical trial is to compare the maintenance of socket volume in the groups treated by a resorbable regenerative membrane (Plenum® Guide) covered or not with mucous tissue, with control without treatment. The main question it aims to answer is the effectiveness of the Plenum® Guide membrane in the process of guided bone regeneration, exposed or not, through the preservation and neoformation of bone tissue in the tooth extraction socket procedures.

Description:

Patients will be submitted to tooth extraction, the surgical procedure of guided bone regeneration using regenerative membranes and synthetic bone graft, and subsequent installation of dental implants. The 05 groups will be compared to observe if the proposed medical devices effectively will maintain the socket's bone volume during the healing phase before the installation of the dental implants (1. socket filled only with clot, 2. socket associated with exposed absorbable membrane, 3. socket associated with covered absorbable membrane, 4. socket filled with synthetic bone graft and covered absorbable membrane, 5. socket filled with synthetic bone graft and exposed absorbable membrane).
