The biofoam impression system that we use to get the information necessary to fabricate your custom orthotic device, is a simple and accurate way to get the measurements and arch contours we require.
We can also get the information that we need from neutral position non-weight bearing slipper casts. These are the types of impressions preferred by most podiatric physicians.
Certainly some of the information about arch characteristics would be different between non-weight bearing impressions and partially weight bearing impressions. As long as our physicians and technicians here at Theta differentiate between the different measurement techniques, a proper prescription can be made.
The biofoam impression technique I use on the internet is quick, clean, and easy to get right.
Our current research protocol prescribes only Digital Theta Orthotics. Both foot contours and angular corrections (Theta) are defined mathematically, and saved in 3 dimensional software files. These 3 D files are then printed on a Rapid Prototyping Printer. Molds are made from the printed parts and used to create our Digital Theta’s.
The same Measurements that we have taken from biofoam impressions, neutral position non weight bearing (Root) casts, and lateral weight bearing x-rays, for over 25 years are used to custom fit our new digital treatment products today.
