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.
Claims5
A method of preparing an orthotic appliance for correctly supporting a foot comprising the steps of:
- attaching a heel bisector having at least two portions to a foot;
- measuring the foot topography;
- measuring an angle formed by the at least two portions of the heel bisector;
- translating the measured foot topography and the measured angle into a three dimensional mathematical model;
- and
- forming the orthotic appliance in accordance with the three dimensional mathematical model.
A method of preparing an orthotic appliance for correctly supporting a foot comprising the steps of:
- attaching a heel bisector having at least two portions to a foot;
- measuring the foot topography;
- measuring an angle formed by the at least two portions of heel bisector;
- translating the measured foot topography and the measured angle into a three dimensional mathematical model;
- adding corrections through a computer to the three dimensional mathematical model;
- relaying the three dimensional model and added corrections through the 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.
