ABSTRACT:
A method for fabricating three directional dental prosthetics. A wax setup of the patient's arches containing artificial dentures is prepared. The wax setup is tried in the patient's mouth to determine centric occlusion. A matrix of the setup is prepared when the centric occlusion is satisfactory. A setup of pumice teeth is then prepared by pouring a pumice compound into the matrix and allowing the compound to harden. A duplicate setup containing pumice teeth is prepared by transferring the pumice teeth onto duplicate models of the patient's upper and lower arches. The duplicate setup is then mounted in the patient's mouth and incisal-occlusal surfaces corresponding to the patient's natural mandibular movement are abrasively milled on the pumice teeth by exercising the duplicate setup in the patient's mouth. Incisal-occlusal surfaces milled in the pumice teeth are then mechanically reproduced on artificial dentures in the wax setup from the duplicate setup on a mill-in-jig.
