Hydroxylapatite and fibrin glue mixture in a subperiosteal tunnel for ridge augmentation

The present investigation was undertaken to evaluate combining the use of a human fibrin sealant and hydroxylapatite particles to augment a tissue expanded lower edentulous atrophic ridges. The procedure was carried out on seven subjects not amenable for rational dentures. Results proved that the technique could efficiently overcome the problem of granules migration. It is simple, easy and leading to predictable well moulded augmented ridges with minimal resorption
