Dental model articulator

A dental model articulator, comprising:

• a pair of base members configured such that dental models for upper and lower jaws are respectively fastened thereto;
• and an upper fastening means and a lower fastening means to which proximal ends of the respective base members are removably fastened, the upper fastening means and the lower fastening means being coupled to each other by a rotating shaft so as to be rotatable relative to each other,
• wherein the upper fastening means comprises:
• a fastening member to which the corresponding base member is fastened;
• a rotating member to which an end of the fastening member is fastened, the rotating member being rotatably coupled to the lower fastening means by the rotating shaft;
• and
• a reciprocating means provided between the fastening member and the rotating member, the reciprocating means supporting and guiding the fastening member such that the fastening member reciprocates toward and away from the rotating member.
