Fabrication  Three Dimensional Volumetric Casting  Cast Correction/Modification  Orthosis Manufacture or milling  Grinding and Finishing

Three Dimensional Volumetric Casting  Plaster of Paris  Casting Foam  Direct Laser Scanning  Contact Digitizing  Wax Casting Currently “Subtalar Joint Neutral” is the industry standard for casting

Cast Correction  Done to allow the fabrication of a device that is both functional & comfortable  Technique is based on the casting method used: CAD/CAM Software for laser scans, and contact digitization CAD/CAM Software for laser scans, and contact digitization By hand, using plaster of Paris for Plaster, Foam and wax casting By hand, using plaster of Paris for Plaster, Foam and wax casting Plaster, foam and wax can also be scanned into CAD/CAM software packages Plaster, foam and wax can also be scanned into CAD/CAM software packages

Orthosis Manufacture/Milling  Creation of the orthosis using the corrected 3D foot cast, or milled directly from manufacturing material  Must be made from the patients casts or scans, and made from raw materials to be truly “custom made”  No “Library Devices” or Prefabricated devices that are simply modified

Grinding and Finishing  Grinding of orthosis to the appropriate shape to fit in shoe; done by hand  Addition of posting, padding and topcovers are the final stages before the patient’s dispensing appointment

Dispensing Appointment  Booked for minutes  Educate patient on function of devices, break-in process etc.  Fit devices to footwear  Further gait analysis to ensure device efficacy and function

Footwear; An entire presentation on it’s own  Patient Measures Heel to toe Heel to toe Heel to ball Heel to ball Width Width Girth Girth  Last shape  Midsole construction  Closures  Upper Design
