Abstract

In a completely edentulous patient who cannot have implant-retained overdentures due to medical history and economic circumstances, a suction-effective complete denture utilizing the closed-mouth impression technique is being used to secure high retention. In this case, both a conventional complete denture using the open-mouth impression technique and a suction-effective complete denture using the closed-mouth impression technique were fabricated for a single completely edentulous patient. The results demonstrated that both methods provided excellent outcomes in terms of function, esthetics, and patient satisfaction. Conventional complete dentures increase the area of denture-bearing pressure to ensure retention and stability, whereas suction-effective complete dentures achieve retention by sealing the entire border of the denture. Since there are characteristic differences in the clinical and laboratory procedures due to differences in the concept of denture fabrication, this was compared through this case report.

의과적 병력 및 경제적인 상황으로 인하여 임플란트 유지형 피개의치가 불가능한 완전 무치악 환자에서 총의치의 높은 유지력을 확보하기 위해 폐구 인상 방식의 흡착형 총의치 제작 방식이 활용되고 있다. 본 증례에서는 단일 완전 무치악 환자에서 개구 인상 방식의 전통형 총의치와 폐구 인상 방식의 흡착형 총의치를 함께 제작해 비교해보았으며, 기능 및 심미 그리고 환자 만족도 측면에서 두 방식 모두 우수한 결과를 확인할 수 있었다. 의치상 내압 면적을 확대하여 의치의 유지와 안정을 확보하는 전통형 총의치와 의치상 전체 주위를 봉쇄하여 의치의 흡착을 확보하는 흡착형 총의치는 의치 제작 개념의 차이로 임상 및 기공과정에서 특징적인 차이를 보이기에 본 증례를 통해 이를 비교해보았다.
