초록
임플란트를 이용한 고정성 보철 치료에 있어 디지털 기술의 활용은 환자의 임상적, 방사선학적 정보를 통합하여 진단 및 가상 수술을 통해 예지성 있는 치료를 가능하게 한다. 기존의 디지털 스캐닝 방법은 치유지대주 제거 및 스캔 바디 연결 등 여러 번의 구성요소 착탈이 필요하다. 이러한 점을 고려하여 개발된 스캔 가능한 치유지대주는, 스캐닝이 치유 지대주 상에서 직접 수행되어 연조직 봉쇄가 유지되며 스캐닝이 간소화된다. 악간관계 채득시에도 디지털 기술을 활용할 수 있는데, 최근에는 수술 가이드, 환자 맞춤형 스캐닝 장치 또는 임시의치 내면 스캔 등을 이용해 무치악 환자들의 악간 관계를 채득하는 여러 디지털 기술들이 보고되고 있다. 본 증례에서는 스캔가능한 치유지대주 및 임시의치 내면 스캐닝을 통한 악간 관계 채득을 통해 고정성 임플란트 수복치료를 시행함으로써 치료과정을 간소화하고 심미적, 기능적으로 우수한 임상 결과를 얻었기에 보고하고자 한다
Abstract
The use of digital technology in fixed prosthetic treatment using implants enables predictive treatment through diagnosis and virtual surgery by integrating clinical and radiological information of patients. Existing digital scanning methods require several components to be removed, such as removing the healing abutment and connecting the scan body. In the scannable healing abutment developed in consideration of this point, scanning is performed directly on the healing abutment, maintaining soft tissue sealing and simplifying scanning. Digital technology can also be used when obtaining the intermaxillary relationship. Recently, various digital technologies have been reported to acquire the intermaxillary relationship of edentulous patients using surgical guides, patient-specific scanning devices, or scans of the inside of temporary dentures. In this case, the implant-supported fixed prosthesis treatment was performed through scanning the scannable healing abutment and the inner side of the temporary denture to obtain the intermaxillary relationship, thereby simplifying the treatment process and obtaining aesthetically and functionally excellent clinical results
