Abstract

The biomechanical prognosis of conventional removable partial denture is questionable in case of patient with few remaining teeth or periodontally compromised teeth. In this case, hybrid telescopic double crown RPD may be a successful treatment alternative. Hybrid telescopic double crown RPD has following advantages over conventional RPD: secondary splinting effect between abutments, more vertical stress direction and more convenient in repairing the denture after extraction of abutment tooth. In this clinical case, patient had deep overbite in anteriors and partially edentulous. The maxilla was restored with hybrid telescopic double crown RPD and the mandible was restored with implants and fixed prostheses. Long-term follow-up and supportive periodontal treatment were performed, and satisfactory results were achieved in terms of function and aesthetics.

소수 잔존치가 남아있거나 치주적으로 불리한 경우 전통적인 가철성 국소의치의 생역학적 예후가 불분명하다. 이러한 경우, 하이브리드 텔레스코픽 이중관 국소의치(hybrid telescopic double crown RPD)는 성공적인 치료의 대안이 될 수 있다. 이 치료방법의 경우 지대치 간의 이차고정 효과가 있으며 응력의 방향이 수직적이고, 지대치 발치 시에 의치의 수리가 용이하다는 점에서 전통적인 가철성 국소의치에 비해 장점을 보인다. 본 증례에서는 전치부의 과개교합을 가진 상하악의 부분 무치악 환자에 있어 상악에는 이중관 의치, 하악에는 임플란트 및 고정성 보철치료가 시행되었다. 장기간 동안 경과관찰 및 유지관리 치료를 시행한 결과, 기능 및 심미적인 면에서 만족할 만한 성과를 얻었기에 이를 보고하고자 한다.
