Multidisciplinary management including endodontics, periodontics, orthodontics, anterior maxillary osteotomy and prosthetics in an adult case with a severe openbite

Adult patients frequently have periodontal problems, resulting in a loss of alveolar bone, the migration and tipping of teeth, and interdental spaces. This case report describes the orthognathic treatment of a 33-year-old adult female with a severe openbite. Her labial-tipped maxillary central incisors were affected by severe periodontitis and treated by guided tissue regeneration (GTR). After the presurgical orthodontics, an anterior maxillary osteotomy was performed and the anterior segment was moved distal and downward direction. The patient achieved a stable and satisfactory occlusion after the prosthetic treatment. This report describes multidisciplinary dental management including endodontics, periodontics, orthodontics, oral surgery and prosthetics in an adult case with a severe openbite and periodontitis, and highlights the importance of co-operation of interdisciplinary fields.
