초록
상하악 치열궁의 부조화는 3차원적인 교합의 문제를 일으키며 불안정한 교합접촉에 의해 교합평면의 붕괴와 다수의 치아 상실 및 저작기능의 감소가 발생할 수 있다. 치아 상실로 인한 구치부의 지지 상실과 상하악 치열궁의 부조화로 인한 불안정한 교합접촉 및 부적절한 전방유도를 갖는 경우, 교정치료를 동반한 보철치료를 통해 안정적인 교합접촉과 전방유도를 회복하고, 조화로운 교합관계로의 개선이 필요하다. 본 증례보고는 앞서 언급된 문제들이 복합적으로 나타난 환자를 치과보철과와 치과교정과의 협진을 통해 양호한 구강회복 결과를 얻었기에 이를 보고하고자 한다.
Abstract
Inter-dental arch discrepancy between maxilla and mandible could cause three dimensional occlusal problems, and collapse of occlusal plane, multiple teeth loss and decrease of masticatory efficiency could be observed in patient having unstable occlusal contact. Patient showing posterior bite collapse, unstable occlusal contact and improper anterior guidance should be treated to recover stable centric occlusion, occlusal contact, and anterior guidance in conjunction between prosthodontics and orthodontic treatment. This clinical report describes the favorable results of orthodontic and prosthodontics rehabilitation of patient with above mentioned problems.
