As new technology comes out you may find yourself asking, What is the best orthotic casting technique? well we are going to help you decide the pros and cons of a few different techniques. We will look at plaster casting, foam box impression and 3D scanning.

Plaster Casting Technique

Plaster casting was the gold standard of casting techniques for a long time. This is due to it being non-weight-bearing so the podiatrist can control the patients foot position more. This is where a plaster of Paris slipper is made of the patients foot. However, over time this method has fallen out of popularity due to its timely and messing application. Furthermore, it can be fatiguing on the podiatrist and can be easily messed up if the foot is not kept in the correct position. Also, plaster casts take up room in the practice and need to be mailed to an orthotic laboratory costing money.

Foam Box Impression

Foam box impression is much quicker and easier than plaster casting. This is where a patients foot is pressed into a foam leaving an impression. This technique provides a snapshot of the foot in a semi-weight-bearing position. This is thought to be more reflective of the foot during gait. However, it is not without its downfalls. Due to needing to push the foot into the foam, the position of the foot can change altering the impression. A foam box impression will also need to be mailed off to a orthotic laboratory increasing costs.

3D Scanning

This is the most recent method to come out of the woodwork. This can be done either non-weight-bearing or semi-weight-bearing depending on the device used. This method is fast, clean and is all done digitally so no need for mailing costs. Furthermore, making copies of orthotics is easy as scans can be stored and used multiple times. The quality of the scanner used is responsible for the quality of the scan.
