초록
과도한 치아의 마모는 치아의 병적 변화, 교합 불균형, 기능 및 심미적 문제를 일으키며 악관절과 근육의 문제를 일으킬 수 있는 수직고경의 감소를 야기할 수도 있다. 수직고경의 감소가 발생한 경우, 전악보철수복을 통해 수직고경을 회복시켜 주기 위해서는 정확한 진단이 중요하다. 본 증례는 59세 남성으로 전반적인 치아의 마모와 파절로 인한 수직고경의감소 및 비심미성을 해결하기 위해 전악 지르코니아 보철 수복을 시행하였다. 생리적 안정위, 견치간 거리 등을 분석하여 수직고경을 3 mm 거상하기로 하였고 전악 왁스업 후 임시치관을 제작하여 6개월동안 사용한 뒤 이를 이용하여 지르코니아 최종 보철을 완성하였다. 1년 6개월 경과 관찰하여 만족스러운 결과를 얻었기에 보고하는 바이다.
Abstract
Severe dental attrition causes pathological changes of the tooth, imbalanced occlusion, and functional and aesthetic complications and can also result in a decrease in occlusal vertical dimension that can incur temporomandibular joint and muscular complications. Before restoring the vertical dimension with full-mouth prosthetic restorations, it is important to determine the amount of vertical lifting through complete diagnosis. In this study, a 59 year-old male patient with generalized attrition and fracture of teeth was treated with full-mouth zirconia prosthetic restoration in order to recover vertical dimension and aesthetics. Through the analysis of physiologic rest position and inter-canine distance, the treatment was planned for lifting 3 mm in vertical dimension. Interim crown were fabricated after full-mouth wax up, having the patient use for 6 months. The final monolithic and bilayered zirconia restorations were completed. The patient showed satisfaction in function and aesthetics for 18 months of follow-up since delivering the final restorations.
