ABSTRACT:
The present invention relates to an article for use in creating a prosthetic denture device that is an impression tray or a denture component formed of a set of hard teeth bonded within a frame assembly formed of a permanent substantially rigid hard frame portion and an adjustable frame portion that is integrally joined to the rigid frame portion and forms part of the frame assembly. The adjustable frame portion is formed from a second composition that is centrifugally cast, and which when cured becomes rigid but not completely polymerized and therefore capable of being subsequently remolded with finger pressure when elevated in temperature. In this manner the adjustable frame portion is remoldable and conformable to desired portions of the oral cavity in the creating of an artificial denture, and the rigid frame portion formed from the first composition concurrently remains fixed as the adjustable frame portion is remolded.
