Ridge Preservation Using Xenogenic Bone Graft and Pre-hydrated Collagen Membrane

This pilot multicentric randomized controlled clinical trial is aimed at evaluating the composition of the new-formed tissue into the dental socket after 6 months from tooth extraction and the application of a combination of xenograft bone granules and collagen membrane. Extraction sites will be either grafted with Dentsply Symbios Xenograft Granules and covered with Dentsply Symbios pre-hydrated Collagen Resorbable Membrane or grafted with Geistlich Bio-Oss Collagen and covered with Geistlich Bio-Gide membrane. Results will be compared to spontaneous socket healing.
