Abstract:
A method of fabricating a flexible retentive bite block, comprising the steps of:a) making a duplicate of an original lower casting so as to form a lower duplicate casting, wherein the original lower casting has a gum, teeth with supra bulges and posterior portions with bite surfaces, and wherein the lower duplicate casting has teeth; c) determining if a lower ball clasp is to used; d) putting the lower ball clasp on the lower duplicate casting, if answer to step c) is yes; e) putting the lower duplicate casting in a heat pressure former; f) positioning at least one plastic spacer sheet on the teeth of the lower duplicate casting; g) activating the heat pressure former, causing the at least one plastic spacer sheet to melt and conform to the teeth of the lower duplicate casting, forming a conformed plastic spacer layer thereon; h) removing the lower duplicate casting with the conformed plastic spacer layer thereon from the heat pressure former; i) putting the lower duplicate casting with the conformed plastic spacer layer thereon in an articulator; j) putting a flat plastic spacer on a bottom of a female hinge part using a was luting agent; k) putting a male hinge part into the female hinge part and tacking together with the wax luting agent, forming an assembly; l) affixing a pair of the assemblies on the conformed plastic spacer layer, at the bite surfaces of the posterior portions of the teeth of the lower duplicate casting, utilizing the wax luting agent; and m) ascertaining that the pair of assemblies are parallel to each other so as to form a lower assemblage.
