ABSTRACT:
A prosthetic preform comprised of a hard base into which are molded the posterior prosthetic teeth, with the anterior prosthetic teeth being mounted in a waxy material contained in a cavity or cavities disposed in the hard base. The preform is further provided with a formable deflectable layer secured to the hard base structure and adapted to be fit to the general contours of the wearer's mouth with an impression material used to line the tissue surface of the deflectable layer to obtain an impression of the intimate detail of the edentulous tissue. The anterior teeth may thus be adjusted in position during fitting and/or anatomical features carved. A mold is made of the anterior teeth and exposed waxy material after fitting which allows casting the fitted anterior teeth in hard base material to the remainder of the hard base structure. The preform may be directly used to provide a prosthetic denture by using an impression material which is bondable to and cures the deflectable layer, or alternatively the fitted preform may be conventionally flasked and hard base material cast around and to the hard base in a resultant mold cavity after removal of the deflectable layer.
