[Treatment of a patient with advanced periodontitis].

This case report presents the planning and clinical treatment of a patient with advanced periodontitis and insufficient prosthetic reconstruction. After initial therapy with extraction of the unrestorable teeth, periodontal surgery was performed partly by means of the implantation of hydroxyapatite into bony defects. The prosthodontic treatment consisted of a fixed/removable prosthesis in the maxilla, together with a shortened teeth arch in the mandible. This clinical treatment, combined with regular recalls, has ensured the patient a functional and esthetic reconstruction for a period of 4 years.
