Abstract  

After tooth extraction, some biological tissue repair phenomena occur. Invagination of the gingival epithelial tissue and subsequent resorption of the alveolar bone walls is expected. Clinically, bone resorption can compromise the future installation of osseointegrated implants, hindering the rehabilitation of edentulous areas. Guided Tissue Regeneration and Guided Bone Regeneration techniques can be used to prevent post-tooth extraction bone resorption. These techniques should also be associated with more cautious and preservative extractions to safeguard regenerative results. The polypropylene membrane has been used after tooth extraction with the main aim of maintaining and immobilising the blood clot inside the alveolus and, due to the possibility of exposure to the oral environment, without suffering contamination or adsorption of dental biofilm and subsequent infection. The purpose of this article is to present the case of the use of a polypropylene membrane after the extraction of a molar, in order to preserve and maintain bone tissue for the immediate installation of an osseointegrated implant and the respective implantoprosthetic rehabilitation. The case has been followed up for 12 years.
