STANDARD LAB PROCESS
CAD CAM Positive Model Vacuum Formed

FOOT MODEL DATA
Stored indefinitely

ADVANTAGES
• Yields an accurate and precise foot model
• Quick and clean
• Eliminates shipping order to laboratory (digital transfer)

DISADVANTAGE
• Accuracy during frame design process is lost due to software and economic limitations.

CLINICAL PEARL
To achieve a balanced 3D scan, suspend foot with heel, 1st and 5th metatarsal heads in level plane while achilles tendon is plumb-lined with Anterior Superior Iliac Spine

3D Foot Scanner is a modern foot impression method that eliminates shipping impressions to the orthotic laboratory. High quality 3D scanners collect point clouds, sets of data points in space, of patient’s feet which are converted to mesh modules through a process referred to as surface reconstruction. Most clinical scanners can convert these reconstructions in many file formats; however, the most popular are Stereolithography files (STL). Some clinical scanning hardware and software has encrypted mesh modules in other file formats. Kevin Orthopedic can accept foot impressions in the format of STL files and from various 3D clinical scanners, including but not limited to:

• Structure Sensor by Occipital
• VeriScan Podiatric Scanner (VPS)
• DelCam iQube
• TOM-CAT Foot Scanner
• Sharp Shape Foot Scanner
• Elinvision Scanner

Note: Although most 3D scanners are capable of capturing high quality detail in high resolution (i.e. 0.5mm for Structure Sensor), the final orthotic frame will have a higher variation congruency than plaster or foam impression methods with positive plaster model vacuum formed fabrication. The cause of this variation is due to the CAD software program’s rendering. Orthotic lab CAD technicians are economically very limited in time to create the perfect congruent orthotic frame matching the foot impression contour. Thus CAD software shortcuts are used to shorten the timespan to design the file resulting in a larger variation in shape and contour of the completed orthotic frame design. If more time was economically feasible, a CAD technician could spend several hours creating the CAD file. However this would significantly increase the cost of the process.
