Surgical Treatment of Mandibular Furcations Using a Xenograft With/Without a Collagen Membrane

Cliniques universitaires Saint-Luc- Université Catholique de Louvain19 enrolled

Overview

The aim of the study was to perform a randomized controlled clinical study in order to compare the effects of a bovine derived xenograft (with 10% collagen) + a bioabsorbable membrane (control group, CG) vs a bovine derived xenograft (with 10% collagen) alone (test group, TG) on the surgical treatment of mandibular type II furcation defects. The patients all underwent the same surgical intervention with the only difference between the two groups being the use or not of a collagen membrane.
