Abstract

Introduction: The rehabilitation of the posterior maxilla with implant-supported prosthesis is often complicated by pneumatization of the maxillary sinus. Bone grafting is commonly required in these cases. Over the years, a number of techniques have been developed for this type of reconstruction. Aim: Present and discuss the possibility of alveolar bone regeneration for subsequent placement of oral implants using Fugazzotto’s technique in combination with particulate autograft harvested from the mandibular ramus and a connective tissue pedicle flap to cover the graft. Methods: A case of a 37-year-old woman with a molar perforated during endodontic treatment and indicated for extraction and implant placement is reported. Result and conclusion: The clinical case showed the possibility of grafting of extraction sites combined with atraumatic elevation of the maxillary sinus fl oor can be achieved using non-conventional techniques such as Fugazzotto’s technique associated with alveolar bone regeneration.
