Alveolar ridge preservation using an open membrane approach for sockets with bone deficiency: A randomized controlled clinical trial.

ABSTRACT:

Background

Various approaches are used for alveolar ridge preservation (ARP); however, there is no standard method or material.

Purpose

To investigate the effect of ARP with a dense polytetrafluoroethylene (d-PTFE) membrane and freeze-dried irradiated allogenic bone for sockets with bone deficiency.

Materials and methods

Thirty-four patients (with sockets exhibiting ≥3 mm hard tissue loss in ≥1 walls) were randomized to undergo natural socket healing (control) or ARP with a d-PTFE membrane and freeze-dried irradiated allogenic bone (test group). After 4 months, horizontal and vertical ridge changes were measured using cone beam computed tomography.

Results

Ridge width at l mm below the ridge crest demonstrated significantly less change in the test group (median
