Abstract
An apparatus and method to avoid dental impression material distortion comprised of dental impression triple tray with a flexible hinge rendered inflexible by the curing of a polymer impression compound. Accurate simultaneous impressions of upper and lower impressions and bite registration, with the mouth completely closed and the jaw accurately positioned in centric closure are insured. Spring back of the impression tray frame caused by bite pressure against points on the frame are minimized by allowing the hinge element to initially flex when first placed in the mouth. The impression polymer cures to render the hinged area inflexible.
