Abstract

Comprehensive prosthetic treatment requires considerations from various points of view. The anterior guidance is important factor in prosthodontic treatment of anterior teeth. Lingual surface contour of anterior restoration is so critical that a small mistake of laboratory or clinical process can cause discomfort of patient and disharmony of entire dentition. There are no guidelines for lingual surface contour that fit all patients. Therefore the lingual surface of provisional restoration is most accurately described as a customized one. The dentist transfers the exact information of anterior guidance that has made through long term provisional restoration to the technician. This case introduce that the duplication technique of CAD/CAM system to reproduce the anterior guidance of provisional restoration. This method can improve satisfaction of both patient and dentist.

광범위한 보철 수복 치료는 수복 부위별로 다양한 고려 요소를 필요로 한다. 특히, 상악 전치부의 교합 계획은 다른 부위보다 더 많은 지식과 기술을 요한다. 전방 유도(anterior guidance)를 결정하는 상악 전치부 설면 외형을 제대로 형성하지 못하면, 기능적인 불편감과 함께 전체 치열의 불안정성을 야기한다. 임시 수복물 장착한 상태에서 적절한 조정을 통해 조화로운 전방 유도를 얻었다면 임시 수복물의 설면 형태를 최종 보철물로 정확하게 구현하는 방법에 주의를 기울여야 한다. 본 증례에서는 CAD/CAM (computer-aided design / computer-aided manufacturing) 시스템의 복제 기법을 활용하여 지대치의 디지털 이미지와 임시수복물의 디지털 이미지를 중첩시켜 보다 간편하게 보철물 형태를 복제하였다. 기존의 방법에 비해 술자는 진료실 시간을 줄일 수 있고, 환자는 기능과 심미 모두 만족할 만한 결과를 얻어 이를 보고하고자 한다.
