Abstract
A method and apparatus for preparing an orthotic appliance to correct defects in a foot providing the steps of scanning a foot, creating a three-dimensional model of the corrected foot, milling a positive mold of the corrected foot, forming a uniformly thick orthotic material over the positive mold and milling out the bottom of the orthotic appliance. Also provided is a heel bisector for use in preparing an orthotic appliance.
Claims16
A method of preparing an orthotic appliance for correctly supporting a foot comprising the steps of:
- measuring a foot topography;
- translating the foot topography into a three dimensional mathematical model;
- relaying the three dimensional model and added corrections through a computer to control a milling machine;
- milling a positive mold of the corrected foot topography;
- forming a material over the positive mold to create a formed side and an exposed side;
- and
- milling the exposed side of the material to form a corrected bottom side of the orthotic appliance.
A method of preparing an orthotic appliance for correctly supporting a foot comprising the steps of:
- measuring a foot topography;
- translating the foot topography into a three dimensional mathematical model;
- relaying the three dimensional model and added corrections through a computer to control a milling machine;
- milling negative molds of the orthotic appliance;
- and
- forming a material inside the negative molds to create an orthotic appliance.
A method for preparing an orthotic appliance having the steps of measuring the topography of a foot, translating the topography into a three-dimensional mathematical model and relaying the coordinates to a computer controlled milling machine, wherein the improvement comprises the steps of:
- (a) milling a positive mold of the foot topography;
- (b) forming a material over the positive mold to create a formed side and an exposed side;
- and
- (c) milling the exposed side of the material to form a corrected bottom side of the orthotic appliance.
