초록
임플란트의 장기적인 안정을 위해서는 이상적인 위치와 각도로 임플란트를 식립하는 것이 중요하며, 이를 위해서는 정확한 계획에 따른 정확한 수술과 보철이 중요하다. 본 증례에서는 치조골 흡수가 심하게 진행된 환자에서 CT data 및 진단왁스업을 스캔한 data를 이용하여 CT guided surgery를 시행하고, 단일구조 수복용 지르코니아와 CAD/CAM technique을이용하여 전악 임플란트 고정성 보철로 수복하여 기능 및 심미적으로 만족할만한 결과를 얻었기에 이를 보고하고자 한다.
Abstract
An accurate implant placement with ideal location is significant for long-term success of the implant. An exact evaluation of nearby anatomic structures such as quality of residual bone, an inferior alveolar bone and a maxillary sinus is required. For a prostheticdriven treatment, planned surgery, precise prosthesis and communication with the patient are significant requisites especially for full-mouth rehabilitation. In this case, the patient with severe alveolar bone resorption had a CT guided surgery supported by CT data and the data from scanning diagnostic wax-up. Afterward, edentulous area was restored by full mouth implant-supported prosthesis by using monolithic zirconia and CAD/CAM technique. This paper reports the outcome of the procedure which was remarkable both esthetically and functionally.
