Esthetic-functional recovery of permanent posterior tooth using autogenous biological restoration.

Occlusal morphology and difficult access for cleaning permanent molars result in the buildup of bacterial plaque and the development of caries. One method known as biological restoration was carried out. This technique known as biological restoration, has as main restorative material a fragment obtained from a duly donated extracted human tooth. This case report describes the restoration of an extensively decayed molar through the bonding of a fragment obtained from a third molar extracted from the patient himself. Biological restoration is a low-cost option that offers satisfactory aesthetic, morphological and functional results.The morphological/functional reestablishment of posterior teeth can be obtained through biological restoration, which allows the recovery of properties inherent to the dental structure, offers satisfactory aesthetic results and low cost.
