치조골의 흡수는 외상, 치주질환 혹은 발육성 기형등 에 의하여 발생하고, 심한 치조골흡수 발생시 통상적 인 보철치료 혹은 임프란트 치료로는 구강내의 심미, 기능적수복이 어렵거나 불가능할 수 있다. 따라서 치 조골의 증대를 위하여 과거부터 여러 방법들이 사용 되어 왔다, 최근 치조골 증대를 위하여 가장 많이 이 용되는 방법들에는 골이식술, 골대체물을 이용, 막유 도 골재생술등이 있다.
Severe alveolar ridge resoption sometimes complicates rehabilitation with traditional modalities. Local conditions of the edentulous area may be unfavorable for implant installation. Especially, severe vertical defect of the alveolar bone may hinder the use of dental implants, if done, the function and esthetic aspect will be compromised. Alveolar distraction osteogenesis is an useful method to restore atrophic alveolar ridge vertically. 2 female patients visited our hospital for prosthetic treatment, and trasfered to our department for surgical treatment for prosthetics. But, they could not be treated by traditional full denture and implant because of severe alveolar bone resorption. The alveolar ridge was severely atrophic and vertical augmentation was mandatory to install dental implants in their ideal position. So aveolar distraction and bone graft were done and implants were placed. The patients have been followed up until now.
