The present invention relates to an attachable and detachable dental articulator which, more specifically, can attach and detach a tooth model, prevents the fixated tooth model from being shaken to make a process for manufacturing a prosthetic appliance easy, and has excellent durability. The attachable and detachable dental articulator comprises: a lower jaw fixation tool which has a lower body in an oval shape with an open upper end portion and an open portion of a lower end portion, has a lower portion cutting unit formed on a front side of the lower body, and has a lower fastening unit formed around the lower portion cutting unit to protrude toward the front side and a support which has a hanger unit to allow a horizontal bar of an upper jaw fixating tool, formed to be the same as the lower jaw fixating tool, to be placed thereon and has an elasticity adjustment fixation unit in the shape of &prime??prime formed to be inclined on an upper end portion. An upper cap and a lower cap are inserted in the upper body and the lower body, respectively. The attachable and detachable dental articulator enables a user to join the tooth model to the articulator in a convenient manner and to separate the tooth model from the articulator in an easy manner. Therefore, the attachable and detachable dental articulator can be conveniently used, doe not cause damage to the tooth model, and enables the user to accurately manufacture the prosthetic appliance as location of the tooth model, installed once, does not occur.COPYRIGHT KIPO 2016본 발명은 탈착 가능한 치과용 교합기에 관한 것으로, 더욱 상세하게는 치아모형을 간단하게 탈부착하되 고정된 치아모형이 흔들리지 않아서 보철물의 제작작업이 용이하고, 내구성이 뛰어난 탈착 가능한 치과용 교합기에 관한 것이다.본 발명은 상단이 개봉되고 하단의 일부분이 개봉된 타원형상의 하부몸체가 형성되고, 상기 하부몸체의 전방에는 하부절단부가 형성되며, 상기 하부절단부의 주변에는 전방으로 돌출된 하부조임부가 형성된 하악고정구와 상기 하악고정구와 동일하게 형성된 상악고정구의 가로대가 올려질 수 있도록 걸이부가 형성되며, 비스듬하게 상단으로 ㄷ자 형상의 탄성조절고정부가 형성된 지지대로 구성되는데, 상기 상·하부몸체에는 각각 상·하부캡이 삽입되는 것을 특징으로 한다.본 발명에 의한 탈착 가능한 치과용 교합기에 의하면 치아모형을 교합기에 결합하기 편리하고, 손쉽게 분리될 수 있어서 사용이 편리할 뿐만 아니라,
