Orthognathic surgery for skeletal open bite is considered to be one of the operations which easily causes relapse. A case of recurrent open bite 12 years after sagittal splitting osteotomy for prognathic and skeletal open bite is presented. The patient was a seventeen-year-old female who underwent sagittal splitting osteotomy after preoperative orthodontic treatment for 1 year 10 months. After that, the follow-up was strictly performed for 3 years, while monitoring the tongue habit, the location of temporomandibular joints, and dental reconstruction. However, she stopped visiting our clinic, and 9 years later she revisited our clinic with a complaint of openbite. During this period, various prosthodontic treatments had been performed by another dentist and the maxillary and mandibular dental arches had changed. She had undergone orthodontic treatment for recurrent open bite for 3 months and open bite had been alleviated.
From the experience of this case, it was suggested that a team-approach, including the postoperative treatment by an oral surgeon, orthodontist, and prosthodontist, is needed during therapy for skeletal open bite.
