Abstract

Implant has been an effective treatment option for the patients with oligodontia. However, it still remains unclear when the implant should be placed. Skeletal growth that can appear even after the growth period can lead to infraocclusion of the implant which can cause functional or esthetic complications. In order to minimize these problems, definitive restorations should be placed after the functional and esthetic rehabilitation is achieved through the use of provisional restorations. Definitive restorations made with monolithic zirconia were created by replicating provisional restorations by using the latest CAD/CAM technology. These definitive restorations were delivered to the patient and clinical observation after the treatment showed satisfactory result.

임플란트 술식은 선천적인 다수치 결손을 보이는 환자에 있어서 효과적인 치료옵션이 되어왔다. 하지만 식립 시기에 있어서는 명확한 지표가 없는 실정이어서 논란은 여전히 진행 중이다. 성장기 이후에도 나타날 수 있는 악골 성장은 임플란트 저위교합(infraocclusion)으로 이어질 수 있으며 나아가 기능, 심미적인 면에서 복합적인 문제점을 보이기도 한다. 이를 해결하기 위해서는 임시 수복물을 통해 기능과 심미를 회복하고 적응되는 기간을 거친 후 최종 보철물로 그대로 이행하는 것이 중요하다. 이에 임시 수복물을 최신 CAD/CAM 기술로 복제하여 임시 수복물의 정보를 담고 있는 단일 구조 지르코니아 보철물을 제작하였고 이를 구강내 장착하였다. 치료 종결 후 3개월간의 임상 관찰에서 만족스러운 결과를 얻었다.
