The loss of tissue after tooth extraction is a physiological process, the chronological sequence of biological events occurring during healing of the alveolus results in reabsorption of the alveolar ridge.The purpose of this study was to evaluate a type of membrane, Geistlich Mucograft Seal®, used for post-extraction socket sealing together with Geistlich Bio-Oss®.After tomographic evaluation, tooth fracture was confirmed.A atraumatic technique was used for tooth extraction and filling of the socket with Geistlich Bios-oss® and mucoscopy seal.At six months postoperatively, the computed tomography showed that the bone volume was maintained.It is concluded that Geistlich Mucgraft Seal® and Geitlich Bio-Oss® are materials that can be used as an excellent possibility of maintenance of the socket structure, post-exodontia.
