Tooth model articulator

The present invention provides a tooth model articulator, which ensures stable and easy coupling of tooth models, and which can properly conduct high-quality simulation through free reproduced movements of the coupled tooth models, the articulator comprising: a pair of base members (3) to which maxillary and mandibular tooth models (2) are fixed, respectively; and an upper fixing means (5) and a lower fixing means (6) to which end portions of the base members (3) are detachably fixed, respectively, and which are shaft-coupled by a rotation shaft (4) to be able to rotate with regard to each other, wherein fixing holes (8) are formed through the end portions of the base members (3); the upper fixing means (5) and the lower fixing means (6) are provided with fitting rods (9), respectively, which are inserted into the fixing holes (8) formed through the end portions, thereby ensuring fitting and fixing; the upper fixing means (5) and the lower fixing means (6) are provided with auxiliary fixing means (10), respectively, which pressurize side surfaces of the end portions of the base members (3) and apply pressure to the base members (3) towards the fitting rods (9), thereby supplementing the fixing force; and forward/backward reciprocating means (16) for adjusting forward/backward movements between the tooth models, interval adjusting means (19) for minutely adjusting axial rotation angles between the tooth models, and rotating means (25) for adjusting rotating direction movements between the tooth models, are implemented.
