This devise relates to the articulator, cross the upper member and the lower member of the articulator formed to protrude to the fitting groove in a simple structure to the surface facing the tooth model so as to form integrally the fixed member and shaped to correspond with that, strengthen the fitting groove and the tooth model in the articulator to the holding member via yet simple bond and The purpose is to provide an articulator, and to be separated. Articulator according to the subject innovation, the upper surface of the lower fixed plate made of a member of the plate-shaped pair of fitting grooves for the engagement of the teeth model is protruded to correspond to reach the rear end from the front end to each other a predetermined interval spaced state, a lower fixed plate the rear end side of the first vertical member and the pairs of integrally formed extending toward the image side, the first side of the plane of the upper vertical member " " and has a shape was mounted in the center of the stopper as well as a portion formed a lower member and an intermittent projection is formed in each upper end of the first vertical member When the upper fixed plate made of a plate-shaped member with a pair of engaging grooves for the engagement of the teeth model is protruded to correspond to reach the rear end from the front end to each other a predetermined interval spaced apart condition, and the upper fixed plate side of the second vertical member It is formed integrally extending toward the lower side, the coupling seat 2 to the rotatable state to the first vertical member side of the vertical member at the bottom side of the lower member and the upper member is hoejeonbong provided side engaging in a center layer consists of.본 고안은 교합기에 관한 것으로, 교합기의 상부부재 및 하부부재의 상호 마주보는 표면에 간단한 구조로 끼움홈을 돌출되게 형성하고, 치아모형에는 그와 대응되는 형상의 고정부재를 일체로 형성하여, 끼움홈 및 고정부재를 매개로 교합기에 치아모형을 견고하면서도 간편하게 결합 및 분리시킬 수 있도록 한 교합기를 제공함에 그 목적이 있다. 본 고안에 따른 교합기는, 판형의 부재로 이루어진 하부고정판의 상면에는 치아모형의 결합을
