Abstract

Developing of digital technique, it is possible to fabricate implant prostheses for edentulous area using intraoral 3-dimentional information throughout implant diagnosis and treatment process. It is being changed that from the method using CAD/CAM, producing prostheses by model scanning after conventional impression and model processing, to the method of fabricating implant provisional restorations and customized abutments by digital impression after connecting digital impression copings (scanbody) and implant fixtures without models. But, this digital method has not been actively used for implant prostheses not yet. Specially, it is short of intraoral digital impression cases for immediate provisional restorations of the maxillary anterior implants. The gingival contour impression of maxillary anterior area is very important for esthetic restorations. Accordingly, in this case report, the using a digital impression coping (scanbody) and digital impression by CEREC Omnicam (Sirona, Bensheim, Germany) or Trios (3shape, Copenhagen, Denmark) were introduced for immediate provisional restorations in 3 cases needed a single implant restoration in maxillary anterior area. The clinical results were satisfactory on the convenience and accuracy of digital impression technique and the good esthetics of final restorations.

디지털 기술의 발달로 무치악 부위의 임플란트 수복 시 그 진단과 치료 과정 전반에 걸쳐 구강 내 3차원 정보를 데이터화하여 보철물을 제작하는 것이 가능해졌다. 전통적인 인상채득 방식을 이용하여 모델을 만들고 이것을 스캔하여 보철물을 제작하던 CAD/CAM 이용 방식에서 벗어나 디지털 인상 코핑(scanbody)을 사용함으로써 모델 없이 디지털 인상을 채득하고 임플란트 임시 보철물 및 해부학적 지대주를 제작하는 술식으로 변화하고 있다. 그러나 아직 이러한 술식은 활발히 이루어지고 있지 않으며 특히 심미성이 요구되어 연조직 외형의 인기가 중요한 상악 전치부 임플란트 즉시 부하에서의 사용은 그 사례가 많지 않다. 이에 따라 본 증례 보고에서는 3명의 상악 전치부 단일 임플란트 수복 환자에서 디지털 인상 코핑(scanbody)을 체결한 후 구강 내 스캐너인 CEREC Omnicam (Sirona, Bensheim, Germany) 또는 Trios (3shape, Copenhagen, Denmark)로 디지털 인상채득을 통해 임플란트 지대주 및 임시 보철물을 제작하였다. 그 결과 디지털 인상채득을 통한 편리성, 정확성 그리고 최종 보철물의 양호한 심미성을 얻어 보고하고자 한다.
