Abstract

It is important to produce a provisional restoration reflecting the patient's jaw relation, occlusal plane, lip support, shape of teeth, and occlusion type for fully edentulous patients before making a definite prosthesis. The patient introduced in this study showed bad prognosis of remained tooth after severe periodontal diseases. Therefore, remaining teeth were extracted and replaced with dental implants. Provisional restorations were fabricated and the the patient's vertical and horizontal jaw relationship, occlusal plane, amount of overjet and overbite, size of teeth, and length of anterior tooth were recorded. Provisional restorations were scanned and CAD/CAM techniques were used to fabricate a monolithic zirconia bridge, which contour is identical with the provisional restorations. The patient was satisfied with the treatment results on functional, esthetic aspects and the prosthesis retained stable during the four-month clinical observation period.

완전 무치악 환자에서 전악 수복시 환자 고유의 악간관계, 교합평면의 위치, 구순지지, 치아형태와 교합양상을 알 수 없기 때문에 그 모든 것을 임시의치에 기록한 후 이것을 최대한 최종 보철물에 반영하여 이상적인 보철물을 제작해 주어야 한다. 본 증례의 환자는 치주질환에 의한 다수 치아 동요가 존재하여 예후가 불량한 잔존치아 전악 발거 후 임플란트 식립하여 임시치아에 환자의 수직 및 수평 악간관계, 교합평면의 위치, 수직 및 수평 피개의 양, 치아 크기, 전치부 길이를 기록하였다. 그 후 임시치아를 스캐너와 CAD/CAM 기술을 이용하는 double scanning technique로 복제하여 임시치아와 동일한 형태의 단일 구조 지르코니아 브릿지 보철물을 제작하였다. 치료 이후 4개월간의 임상 관찰에서 환자는 심미적, 기능적으로 만족하고 안정적으로 유지되었기에 이를 보고하고자 한다.
