Aim: Different cell types exhibit distinct physiological behaviors during post-exodontic repair. In this period, alveolar bone repair goes through several phases in which cellular and tissue changes are expected. The resorption of the alveolar bone in height and width is indirectly dependent on the presence of teeth. After tooth extraction, resorption in the vestibular-lingual width is greater than the visible resorption in height of approximately 2 mm. Planning the quantity and quality of resorption can determine the type of prosthetic rehabilitation to be achieved. The guided bone regeneration technique seeks to select the cells producing bone tissue by means of a physical barrier. These totipotent cells differentiate and are the major responsible for the secretion of the extracellular matrix that will be mineralized.
Materials and methods: A case of post-extraction polypropylene membrane is presented, with prospects for future osseointegrated implant and prosthetic rehabilitation. Results: After removal of the membrane, which remained for 10 days, maintenance and immobilization of clot was observed, maintaining a relative thickness of the alveolar ridge. Conclusions: The use of polypropylene membrane, through guided bone regeneration and potentiation of the osteopromotion phenomenon, may be an important adjunct in the treatment of post-extractive alveolar sites for implant-prosthodontic rehabilitation. The polypropylene membrane showed predictability, with lower morbidity for the patient and lower patient costs.
