Abstract

Although physiologic abrasion in normal range need not to be corrected, when hard tissue of teeth are worn abnormally fast, it can cause severe damage and destroy esthetics and, functional structure of occlusion consequently. To establish a correct occlusal plane and space for the patient with worn dentition, it is necessary to increase vertical dimension. However, actual occlusal vertical dimension remains unhanged with compensation for the increase of alveolar bone height equivalent to the decrease of teeth length. A 74-year-old male presented with worn dentition and fractured tooth. Based on the assessment of OVD including clinical findings, full-mouth rehabilitation without increase of OVD was planned. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition without changing occlusal vertical dimension.

정상적인 수준의 생리적 마모는 수정이 필요 없으나, 치아 경조직의 상실 속도가 비정상적으로 빠른 경우에는 치아에 심각한 손상을 야기하고 심미적, 기능적 구조를 파괴할 수 있다. 전반적인 치아 마모를 보이는 환자의 치료를 위하여 전악을 보철로 수복하고, 교합거상이 필요할 수도 있지만, 마모된 전치부의 보철 수복을 위한 가용공간 때문에 수직교합고경에 변화를 주는 경우가 아니면 잘 변경시키지 않는다. 본 증례의 환자는 마모된 치열과 치관 파절을 주소로 내원한 74세 남자 환자이다. 임상검사 결과 구치부 지지에 의해 수직고경의 감소가 없음을 확인하고 수직고경 변화 없이 전악 수복하여 만족할 만한 결과를 얻었기에 이를 보고하고자 한다.
