Abstract

As patients' esthetic expectations increase, there is an increase in demand for cosmetic restorations of anterior and posterior teeth that resemble the natural tooth morphology and color. An example of high-strength all-ceramic systems is zirconia with CAD/CAM application. This case report describes a full-mouth rehabilitation using zirconia all-ceramic crowns supported by upper and lower implants and by a minimal increase in the occlusal vertical dimension in a patient with severe abrasion due to loss of posterior teeth.

환자의 심미적 요구가 증가함에 따라 전치뿐만 아니라 구치부에서도 자연치아와 유사한 색조와 외형을 재현한 보철물에 대한 필요성이 증가하고 있다. 단일 지르코니아와 CAD/CAM 시스템을 통해 이러한 환자의 요구를 만족시키는 보철물 제작이 가능해졌다. 본 증례는 70세 여자환자로 전치부 보철물이 깨져서 보기 싫고 하악 구치부가 없어서 저작이 불편하다는 주소로 내원하였다. 하악 구치의 상실로 교합평면이 붕괴되었으며 과도한 치아 마모 및 수직고경 상실이 관찰되어 치아 상실 부위에 임플란트를 식립하고 수직고경 증가와 함께 지르코니아 고정성 보철물을 이용한 전악 수복 치료를 진행하였다. 치료 후 3년 간 이상적인 교합이 잘 유지되고 기능적, 심미적으로 만족한 결과를 얻었기에 이를 보고하는 바이다.
