Ridge Preservation Using Guided Regenaration, Platelet-rich Plasma and Free Gingival Grafts

The goal of this clinical trial is to learn if ridge preservation methods with dense polytetrafluoroethylene membranes, with d-PTFE membranes and platelet-rich plasma, and with free gingival grafts can reduce vertical resorption of the post-extraction socket walls.

Researchers compared each experimental group to a control group (unassisted socket healing). Participants were randomly allocated to one of the four groups.

Cone-beam computed tomography was performed after the procedure and 3 months post-operatively to evaluate the vertical socket wall resorption.

Ridge Preservation

Procedure

Tooth extraction, socket filling with PRP, deperiostation of the buccal and oral marginal gingiva, placement of d-PTFE membranes and suturing.

Other names: socket preservation

Primary outcomes

  1. Vertical post-extraction resorption of the socket walls

    Time frame: 3 months

    Each socket wall is measured using CBCT right after the extraction and after 3 months to assess the vertical resorption.
