[The use of human lyophilized bone matrix gelatin in oral surgery (preliminary report)].

Clinical application of human freeze-dried bone matrix gelatin (BMG) in the bone-cysts is reported. The BMG is produced at the West Hungarian Regional Tissue Bank in Gyór under principles of the American and European Association of Tissue Banks. BMG was applied to fill bone cysts in maxilla and mandible. The BMG has many advantages in comparison to other materials in the management of maxillofacial cysts. Of 31 cases 28 primary bone-heating have been detected clinically assessed by X-ray and histologically in three cases there was secondary restoration. In the favourable courses very fast and effective restorations have been found. The authors possess very favorable experience on the field of implantation of human bone matrix gelatin and recommend its clinical application at the maxillofacial surgery.
