Abstract

Flabby tissue is not rare for denture wearers. Mucostatic impression technique is necessary due to compromised retention and stability of denture resulting from distortion of mobile flabby tissue. In this report, individual tray was fabricated by model-scanning and 3D printing treatment denture. And then, mucostatic impression for flabby tissue was obtained by using individual tray modified with window technique. Definitive denture was fabricated based on information of treatment denture including incisal pontic arrangement, jaw relationship and occlusion.

진료실에서 치과의사는 flabby tissue가 있는 의치 환자를 흔히 만날 수 있다. Flabby tissue는 인상을 채득할 때 인상재에 의해 변위되어 의치의 유지와 안정을 저해하기 때문에 선택적인 가압을 통해 인상을 채득할 필요가 있다. 따라서 본 증례에서는 개인 트레이에 window를 형성하여 flabby tissue 부위의 무압 인상을 채득하였고, 이 과정에서 모델 스캐너로 치료 의치를 스캔한 후 3D 프린터로 복제하여 개인 트레이를 제작하였다. 최종의치는 치료 의치의 전치 배열과 악간 관계, 교합에 대한 정보를 반영하여 제작하였다.
