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.

Shortened dental arch(SDA) 개념은 여러 현실적인 이유로 적절한 대안이 없을 경우 제 2 소구치까지만 수복이 이루어져도 안정적인 교합과 저작력을 얻을 수 있다는 것으로 자연치와 임플란트를 이용한 수복시 공히 적용되는 개념이다. 본 증례는 2급 지적장애로 인해 치료시 협조를 구할 수 없으며 우식으로 인해 다수의 치아가 상실된 환자로 대구치 부위의 심한 골흡수와 상악동의 함기화 및 상악동염으로 인해 제 2 대구치까지의 수복이 용이하지 않아 가급적 위험요인을 줄이면서 최소한의 전신마취로 치료를 종결하기 위해 SDA 개념을 적용, 제 2 소구치까지만 수복이 이루어졌다. 치료 결과 심미적, 기능적으로 만족할 만한 향상이 이루어졌고 추가적인 저작력의 요구는 없었으며 주기적인 재내원으로 구강위생이 강화되었다.
