Abstract:
A method of making molds for use in forming orthotics comprising the steps of:(a) selecting a multiplicity of corrected replicas of the human foot, each having been made from an uncorrected replica of the human foot having an uncorrected contoured lower surface, each said corrected replica exhibiting a corrected contoured lower surface from which an orthotic can be formed by heating and pressing a thermoplastic blank thereagainst;(b) examining each said corrected replica of said selected multiplicity of corrected replicas to identify those having substantially identical contoured lower surfaces;(c) identifying a plurality of corrected replica subgroups by grouping said multiplicity of corrected replicas which were examined into subgroups in which said corrected replicas which make up each said subgroup exhibit substantially identical contoured lower surfaces; and(d) constructing for each of said plurality of subgroups a mold having an internal cavity which will produce from a formable material placed in said internal cavity a finished orthotic having a contoured upper surface substantially identical to the contoured lower surfaces of said corrected replicas which make up each said subgroup.
