There are multiple means developed to create the basis for the molds, including plaster casts, foam box impressions, and three-dimensional computer imaging.
Over the years podiatrists have developed numerous means to create the basis for their molds, plaster casts, foam box impressions, or three-dimensional computer imaging.
These casts were made by wrapping dipped plaster or fiberglass strips around the foot to capture the form, then letting it dry and harden.
These scans are made by having the patient place the foot onto a specialized flat image scanner that uses light and software to capture and create a 3D model.
This 3D model is then electronically submitted (along with a prescription) to an orthotics lab, where it is used to program a CNC machine that will ultimately produce the orthopedic insert.
