Treatment of a woman suffering from oligodontia and multiple diastemata with insufficient alveolar ridges in both the maxilla and mandible is described in this clinical report. The total number of missing teeth was 11 (excluding the wisdom teeth). The treatment strategy consisted of an interdisciplinary team approach of orthodontic, surgical, and prosthodontic phases. Sinus floor augmentation, alveolar ridge augmentation via vertical alveolar distraction, and lateral augmentation with ramus graft procedures were performed after fixed orthodontic treatment and prior to dental implant placement. Oral rehabilitation of the patient was completed with the placement of fixed prostheses in the maxillary and mandibular posterior edentulous areas. Early dental intervention improved the patient's appearance and minimized the onset of emotional and psychosocial problems.
