초록
본 증례는 완전한 디지털 workflow로 단일 치아 임플란트 지지형 보철물을 즉시 부하하여 수복한 증례이다. 하악 제1대 구치 상실로 내원한 환자로, 구강 스캐너로 구내 디지털 인상채득 후, CT데이터와 디지털 스캔 데이터를 통해 제작한 수술용 가이드를 이용하여 임플란트를 식립하였다. 술 후 1주일 후, 맞춤형 지대주와 임시치아를 체결하여 즉시부하 하였다. 술 후 8주 후 지대주 레벨에서 구강스캐너를 이용하여 디지털 인상채득 후, 술 후 3개월에 지르코니아 최종 보철물을 장착하였다. 본 증례는 환자의 만족도 및 정확성 면에서 만족할 만한 결과를 나타내었으며, 완전한 디지털 과정을 통한 수복 결과 정확성, 심미성, 기능성 면에서 만족할 만한 결과를 나타내었기에 보고하는 바이다.
Abstract
In this case report, immediate loading of an implant-supported single-tooth prosthesis through complete digital workflow. A patient presented for restoration of missing a single tooth in the mandibular first molar. The digital impression was made with intraoral scanner and implant was placed using surgical guide pre-fabricated with pre-operative computed tomography (CT) and scan data. After 1 week later, prefabricated customized abutment and provisional restoration were connected for immediate loading. After 8 weeks later, abutment level impression was taken by intraoral scanner. At 3 months later from implant installation, monolithic zirconia crown were fabricated. This clinical report presents satisfying result in accuracy and patient satisfaction. A completely modeless digital procedure met expectations regarding precision, esthetics, and functionality.
