Abstract

Piezography, prosthetic space recorded by pronunciation, can be used as a reference for arrangement of artificial teeth and polishing surface of a denture. In this case, a 67 year old female patient was presented for new dentures. Old dentures had class II relationship and poor retention. For fabrication of stable dentures, using piezography and lingualized occlusion was planned. After taking impressions with conventional method, conventional denture bases with wax rim were fabricated. Then, additional mandibular denture base was fabricated for piezography. With fast setting silicon impression material, piezography was recorded by using six pronunciations, 'si', 'so', 'me', 'te', 'de', and 'mu'. According to the piezographic space, mandibular artificial teeth were arranged and modified for lingualized occlusion. As a result, the patient was satisfied with new dentures functionally and esthetically.

Piezography는 발음을 이용하여 채득된 보철 공간을 의미하며, 의치의 인공치와 연마면의 위치를 결정하는 참고점으로 사용하게 된다. 본 증례 대상은 67세 여성환자로, 새 의치 제작을 주소로 내원하였다. 기존 의치에서 2급 악간관계와 불량한 유지력을 확인할 수 있었으며, 안정적인 의치를 위해 piezography와 설측교합을 이용하기로 하였다. 통상적인 방법으로 인상 채득 후 주모형 상에서 상하악 기초상과 왁스 교합제를 제작하였고, 별도로 piezography를 위하여 하악에 추가적인 기초상을 하나 더 제작하였다. 이 추가 기초상에 실리콘 인상재를 적용 한 뒤 '시', '소', '메', '테', '데', '무' 여섯개의 발음으로 piezography를 채득하였다. 하악 인공치를 이 보철공간에 맞추어 배열한 뒤, 형태를 수정하여 설측 교합을 부여하였다. 그 결과, 환자는 새로운 의치에 기능적, 심미적으로 만족하였다.
