Abstract

Loss of posterior support may cause extrusion of antagonistic teeth and excessive wear of remaining teeth which often leads to the destruction of the occlusal plane. In such cases, it is critical to verify the need to increase vertical dimension of occlusion (VDO). Should you increase VDO, provisionalization is crucial in evaluating function and esthetics. Double scanning technique is a useful method when fabricating definitive restoration that mimic provisional restoration. In this case, a patient with apparently no loss of VDO and insufficient interocclusal space for dental materials due to loss of posterior support and extrusion of antagonistic teeth was rehabilitated using double scanning technique.

구치부 지지 상실은 대합치의 정출, 잔존 치아의 교모 등으로 교합평면의 부조화와 보철수복공간 부족을 야기할 수 있다. 이러한 환자는 수직교합고경 분석이 선행되어야 하며, 수직교합고경의 증가가 필요한 경우 적절한 임시 수복물 제작을 통해 기능적, 심미적 측면을 평가해야 한다. 최종 보철물 제작에 임시 수복물의 정보를 반영하는 방법으로 이중 스캔을 이용할 수 있다. 본 증례는 구치부 상실 및 대합치의 정출로 보철수복공간이 부족하나 수직교합고경의 감소가 미미한 환자에서 이중 스캔을 이용하여 수복하였다.
