Abstract

The patient was a 69-year-old male who had decreased VDO and overbite of the anterior teeth due to severe teeth wear. Complete mouth rehabilitation was planned to restore esthetics and function. Due to the presence of a subgingival finish line, poor fit of the margin of the temporary crown, and insufficient oral hygiene management, gingival overgrowth and bleeding occurred in many teeth, and inaccurate impressions were taken. After dividing each arch and taking partial impressions, a transfer coping was made using pattern resin on each working model die, and after being placed on the abutment teeth, a master cast was made through pick-up impression taking to produce prosthesis. In this case, the final prosthesis produced on the second master cast were fitted in terms of proximal contact, marginal fit, vertical occlusal dimension, facial appearance, esthetics, and occlusion. After complete mouth rehabilitation, the patient was satisfied with function and esthetic appearance.

본 증례의 환자는 69세 남환으로 심한 치아 마모로 인하여 수직교합고경 감소 및 전치부의 과개교합을 보였고 심미 및 기능의 회복을 위하여 완전 구강 회복술을 계획하였다. 치질이 부족한 치아들의 치은 연하 마무리선의 존재 및 임시치관의 변연부 적합 불량, 구강 위생 관리의 미흡 등으로 다수 치아의 치은 과증식 및 출혈이 일어났고 부정확한 인상채득이 이루어졌다. 각 악궁을 분할하여 부분 인상을 채득한 후 각각의 작업모형 다이상에서 패턴레진을 이용하여 트랜스퍼코핑을 제작하였고, 구강 내 지대치에 위치시킨 후 픽업인상채득을 통해 하나의 주모형을 제작하여 보철물을 제작하였다. 2차 주모형 상에서 제작된 최종보철물은 인접면 접촉, 변연 적합도, 수직교합고경, 안모, 심미, 교합 면에서 술자와 환자 모두 만족하였기에 이를 보고하고자 한다.
