Tooth loss and periodontal disease often leave inadequate alveolar bone volume for simple implant placement. Alveolar bone grafting from an intraoral donor site offers a successful treatment option to regain the original bone volume. The mandibular retromolar area provides a cortical graft that is well-suited for a monocortical or particulated guided tissue regeneration technique and is associated with a low morbidity for the patient. This article describes the technique for easy handling of a bone graft from the mandibular retromolar area and the healing process.
