Abstract

Soft tissue collapse around prepared teeth and pontic is inevitable after removal of the provisional restoration during the impression taking procedures. When inserting gingival retraction cord, soft tissue is displaced to an undesired contour. Viscosity of impression material also causes gingival displacement. Therefore, the consideration to transfer the prosthetically contoured soft tissue to master cast is required, especially in the esthetic area. In this report, the methods to maintain the soft tissue contour and transfer to the mastercast will be introduced. Harmonious contour of the soft tissue can be achieved with provisional restoration and be transferred to the master cast with two different techniques mentioned in this case report.

고정성 국소의치를 이용한 수복 시 보철물 자체의 심미성뿐 아니라 보철물과 조화로운 주변 연조직의 형성 또한 중요한 요소이며, 임시보철물을 이용하여 조화로운 연조직의 형태를 형성할 수 있다. 임시보철물을 통해 형성한 연조직의 형태는 적절한 형태를 갖는 최종 수복물을 제작하는데 필요한 정보를 제공할 수 있도록 최종모형으로 정확하게 복제되어야 한다. 그러나, 임시보철물 주위 연조직의 형태는 인상과정 또는 인상재의 압력 등으로 최종 모형으로의 복제가 어렵다. 따라서, 임시보철물을 이용하여 형성한 구강내의 연조직 형태를 모형으로 복제하여 연조직과 조화로운 최종 수복물을 제작하는 서로 다른 2가지 방법을 본 증례보고에서 소개한다.
