Abstract

Without proper treatment on the multiple tooth missing area, the lack of posterior support and the supra-eruption of the teeth cause many severe complications of occlusion, vertical dimension and masticatory function. This report is a case of full-mouth rehabilitation of a patient with loss of posterior support and collapsed occlusion due to missing teeth area left untreated for a long time. The patient who is 68-year old male patient had some teeth fallen out while removing his old maxillary denture and was complaining about pain in the region of anterior teeth due to traumatic contact. The vertical dimension was corrected by 4 mm from the top cervical point of the canine through various evaluations and the edentulous area was treated with the implant fixed prostheses through computer guided implant surgery based on the diagnosis and treatment plan for definitive prostheses supported by computed tomography (CT) data analysis and CAD-CAM (Computer-aided design/computer-aided manufacturing) technique. After full mouth rehabilitation, the patient was very satisfied with remarkable improvements in mastication, function, and aesthetics.

다수 치아의 상실 상태로 장시간 지속시 구치부 지지의 부족 및 치아들의 과정출이 발생되어 교합 부조화, 수직고경 상실 및 기능 장애 등의 심각한 문제가 초래된다. 본 증례는 장기간 다수치아 결손으로 인하여 대합치가 정출하면서 교합평면의 붕괴가 일어난 환자의 완전 구강 회복에 관한 증례이다. 상기 환자는 서울대학교 치과병원 치과보철과로 내원한 68세 남환으로 오래된 상악 의치를 빼다가 치아가 함께 발거되었으며, 하악 전치부가 상악 전치부와 강하게 닿아서 불편함을 호소하며 내원하였다. 여러가지 평가를 통해 수직고경을 4 mm 거상하였으며, 무치악부는 진단 및 치료계획시 설계한 최종 보철 수복물 제작을 고려하여 정확한 임플란트 식립을 위해 CAD-CAM (Computer-aided design-computer-aided manufacturing) 기술을 이용한 Computer guided implant surgery를 시행하고, 임플란트 고정성 보철 수복으로 진행하였고, 환자는 저작, 기능 및 심미 모두 큰 개선에 만족하였다.
