Abstract

Treating patients with severely worn dentition often requires comprehensive prosthetic treatments. Oral rehabilitation and long-term stability could be achieved by analyzing the cause of the wear and changing vertical dimension. The temporary restoration procedure is executed and patient's adaptation is evaluated by long-term observation when treatment is accompanied with increasing vertical dimension. In this case, 54 year-old male presented with worn dentition and esthetic dissatisfaction. In oral manifestations, severely worn dentition with attrition and erosion is diagnosed. To evaluate change of vertical dimension, interocclusal rest space, facial appearance, pronunciation, clinical crown length, distance from incisor edge to labial vestibule are evaluated. Consequently, 2.5 mm increase of vertical dimension that based on articulator incisal pin is determined. After 8 weeks stabilization period with temporary prostheses, definitive prostheses are fabricated. After 6 months follow up period, satisfactory outcomes were achieved both in functional and esthetic aspects through this procedure.

심한 마모를 가진 환자의 치료에서 광범위한 보철 수복을 필요로 하는 경우가 있는데, 마모의 원인과 수직 고경의 변화 유무 등을 판단하여 현재 구강상태의 회복과 장기간의 안정성을 이루어야 한다. 수직 고경을 증가시킬 때는 임시 수복을 하고 장기간의 관찰을 통해 환자의 적응을 평가해야 한다. 본 증례의 환자54세 남자 환자로 전반적인 치아 마모와 심미적 불만족을 주소로 내원하였다. 환자의 구강 내 소견 상 교모와 부식이 동반되어 과도한 마모가 발생한 것으로 진단하였다. 수직 고경의 변화를 평가하기 위해 안정위시 악간공극, 발음, 안모, 심미, 임상적 치관 길이, 중절치 절단과 순측 전정과의 수직거리 등을 평가하였고, 교합기의 incisal pin기준으로 수직 고경을 2.5 mm 증가하기로 하였다. 임시 보철물을 이용하여 8주의 안정화 기간 이후 최종 보철물을 제작하였다. 6개월 간 경과 관찰 결과 기능적, 심미적으로 양호한 결과를 보였다.
