Abstract

Class III malocclusion with mandibular protrusion can be divided into skeletal and pseudo malocclusion due to tooth displacement. For skeletal malocclusion, favorable treatment results can be obtained by establishing an appropriate vertical and horizontal intermaxillary relationship in order to secure a restoration space and obtain aesthetic and functional results. In this case, complete mouth rehabilitation was performed using an implant and a fixed prosthesis in a patient with mandibular protrusion and anterior teeth wear and reduced occlusal vertical dimension. After cast analysis and digital diagnosis, a provisional restoration with increased vertical dimension was fabricated to secure posterior support and evaluate stable centric occlusion. With the definitive prosthesis reflecting the provisional restoration, favorable function and aesthetics were obtained.

하악전돌 양상을 보이는 3급 부정교합은 골격성 3급과 치아변위에 의한 가성 3급으로 나눌 수 있다. 골격성 부정교합은 수복공간 확보 및 심미적, 기능적 결과를 얻기 위해 적절한 수직 및 수평 악간관계를 설정하면 양호한 치료결과를 얻을 수 있다. 본 증례는 하악 전돌과 전치부 마모 및 교합수직고경의 감소를 보이는 환자에서 임플란트와 고정성 보철물을 이용하여 완전구강회복을 시행하였다. 모형 분석과 디지털 진단을 시행 후 수직고경을 거상한 임시수복물을 제작하여 구치부 지지를 확보하고 안정적인 중심교합을 평가하였고, 이를 반영한 최종보철물로 양호한 기능과 심미를 회복할 수 있었기에 이를 보고하는 바이다.
