초록

구치 근관 치료의 임상적 성공은 근관 치료 후 수복에 의해 결정된다. 다양한 방법들이 근관 치료된 구치를 수복하기 위해 제안되고 있다. 소아청소년치과학 영역에서 근관 치료가 필요한 맹출 진행 중인 영구 구치의 전통적인 포스트 코어 및 전장관 수복은 어려움이 많고 과도한 치질 삭제를 유발한다. 치수강을 통한 적절한 유지력이 제공된다면 엔도크라운(Endocrown)은 보존적이고 심미적인 대안이 될 수 있다. 치아 형성은 크라운-코어 일체형의 수복물을 구성하기 위해 치은연과 같은 높이의 버트 조인트(butt-joint) 변연과 치수강 내부 전체의 유지 와동으로 이루어진다. 이 증례 보고는 광범위하게 손상된 부분 맹출된 제1대구치의 엔도크라운을 통한 심미적이고 보존적인 수복의 결과를 기술하고 있다.

Post-endodontic restorations are both important and challenging for clinical success in endodontically treated posterior teeth. Several options have been proposed to restore endodontically treated molars. In pediatric dentistry, restoration using conventional single crowns, especially for partially erupted molars with insufficient retentive tooth structure, has proven to be difficult. However, the endocrown presents a conservative and esthetic restorative alternative to conventional crowns with post-and-core, as it acquires additional retention within the pulp chamber. The tooth preparation consists of a circular, equigingival, butt-joint margin and a central retention cavity in the pulp chamber that helps to construct both the crown and core as a single unit. This case report describes the esthetic and conservative endocrown restorations of erupting permanent first molars with extensive coronal destruction.
