Full mouth rehabilitation of an oligodontia patient with intellectual disability based on shortened dental arch concept: a case report / 대한치과보철학회지

ABSTRACT

Shortened dental arch (SDA) as a treatment goal is the concept that stable occlusion and enough masticatory force can be achieved by restoration to the second premolars when the situation is not favorable. SDA could be applied both natural teeth and implant supported fixed prostheses. This case dealt with a patient who has grade 2 intellectual disability and a lot of missing teeth. Because of intellectual disability, patient cooperation during treatment could not be expected. Therefore every treatment should be done under general anesthesia. In addition to that, ridge resorption around molar area was severe and there were maxillary sinus pneumatization and maxillary sinusitis which increased failure probability. SDA concept was adopted to reduce risk factor and minimize general anesthesia. After the treatment, functional and esthetic improvement was achieved and oral hygiene was fortified by periodic recall check and education.
