ABSTRACT:
A dental articulator adapted for supporting jigs having an extending screw which engages a female thread in a button embedded in the base of a stone dental cast as opposed to the conventional method of supporting such dental casts by means of plaster. The apparatus and method also provides a means by which the dental cast can be removed for further laboratory processing with the assurance that it can be removed and remounted in the articulator into the precise position and relationship of the initial mounting, and also provides a novel method for embedding a button into a dental cast by forming a cavity and pouring a cold setting material such as plastic into which a screw is inserted while the poured button is in the fluid form before final setting.
