In view of the necessary reconstruction, the extensive destruction of the periodontal tissues required a systematic approach to determine the possibilities and the expectations of the patient. The subsequent oral rehabilitation was accomplished with fixed prosthodontics. In the mandible, strategically important anchor teeth were replaced with implants, allowing smaller units to be inserted. The long-term treatment result, however, can only be ensured with the full cooperation of the patient and consistent periodontal maintenance care.
