초록

임시보철물은 고정성 보철물로의 수복 과정에서 지대치 보호 및 기능과 심미성 회복의 측면에서 중요한 역할을 수행한다. 특히 이를 장착한 상태로 최종 수복 전에 장기간의 관찰이 필요한 환자에서 그 중요성이 더욱 강조되나, 상대적으로 낮은 강도로 인하여 잦은 파절이 발생할 수 있으며 이를 방지하기 위해 강화된 임시보철물의 제작을 고려할 수 있다. 이 문헌에서는 교합 수직 고경의 증가를 필요로 하는 환자의 증례를 소개하고자 하였으며, 수직 고경 증가의 영향으로 임시보철물 사용 시 더 큰 부하의 작용 및 장기간의 사용이 예상되었다. 이에 주조 금속 하부구조물을 첨가하여 bis-acryl 레진으로 강화된 임시보철물을 제작하였으며, 약 4개월의 관찰 기간 동안 만족스러운 결과를 보였다.

Provisional restoration plays an important role in the process of restoration with fixed partial denture by providing protection and restoring function and esthetics of abutment tooth. This is especially true in patients requiring use of provisional prosthesis for a long term. However, such situations may lead to higher possibility of provisional prosthesis fracture, and if expected so, reinforcement of provisional prosthesis should be considered. In this article, a patient requiring prosthetic treatment with increase of vertical dimension of occlusion was introduced. Due to increased vertical dimension of occlusion, the provisional restoration was expected to withstand relatively larger amount of load during a relatively long observation period. In order to minimize possible occurrence of fracture, reinforcement of the provisional restoration was sought by insertion of cast-metal framework and by using bis-acryl resin. The reinforced provisional restoration showed satisfactory results during the observation period of 4 months.
