상기 유지구(110)는 지대치(101)의 언더컷을 이용하여 상실부위의 양쪽 치아를 감싸도록 형성되는데, 이때 상기 유지구(110)는 지대치(101)의 내측 전부와 외측 일부를 감싸도록 형성되고, 교합시 수직적인 힘에 견딜 수 있도록 최소 지대치를 감싸줘야 하므로 맞닿는 면이 넓어 공간이 부족한 경우에는 삭제돌기(111)에 대응하도록 지대치(101)의 일측에 최소한의 선택적 삭제가 필요할 수도 있다.The holder 110 is formed to surround both teeth of the loss part using the undercut of the preparation tooth 101, wherein the holder 110 is formed to surround the entire inner and outer portion of the preparation tooth 101 , The minimum abutment should be wrapped to withstand the vertical force at the time of occlusion, so when the contact surface is wide and there is insufficient space, a minimum selective deletion may be necessary on one side of the abutment 101 to correspond to the deletion protrusion 111.
즉 상기 삭제돌기(111)의 결합을 위해 지대치(101)의 일측을 마취 없이 0.5~2.0㎜의 깊이로, 상기 지대치(101)의 상아질을 침범하지 않는 범위 내에서 범랑질만 삭제하는데, 이는 상기 범랑질에서 시멘테이션(Cementation)이 훨씬 강하고 치아 우식을 방지할 수 있기 때문이다.That is, one side of the abutment 101 to the depth of 0.5 ~ 2.0㎜ without anesthesia for the coupling of the deletion protrusion 111, delete only the enamel within the range that does not invade the dentin of the abutment 101, which is the enamel Cementation is much stronger and can prevent dental caries.
이때 상기 지대치(101)의 삭제는 치아 접촉면과 언더컷에 따라 최소 한곳 또는 두 군데를 삭제함이 바람직하다.At this time, the removal of the preparation tooth 101 is preferably deleted at least one or two places according to the tooth contact surface and the undercut.
그리고 상기 지대치(101)에 유지구(110)의 회전삽입을 위해 상기 유지구(110)의 모서리부 상단은 내측으로 라운드진 형태(110a)로 구성되는데, 이는 각진 형태의 경우 회전삽입시 간섭으로 인한 장애로 상기 지대치(101)에 유지구(110)의 삽입이 어렵기 때문이다.And the upper end of the corner portion of the holder 110 is formed in a rounded form (110a) to the rotational insertion of the retainer 110 in the abutment 101, which is an interference when the rotational insertion This is because it is difficult to insert the holding tool 110 into the abutment 101 due to the obstacle.
