There are 7 common methods for capturing a patient’s foot contour

Plaster Slipper Cast

Foam Impression

STS Slipper Sock

3D Foot Scanner

Pedobarography

Existing Positive Model

Redimold

There are 5 different lab methods for orthotic frame fabrication

Tolerances in foot impression methods and fabrication methods produce variable outcomes for how similarly the orthotic frame matches the patient’s foot.

Plaster Positive M.

3D Printed Frame

Direct Mill Frame

Redimold Positive M.

CAD CAM Positive M.

The chart below shows outcomes of shape-contour variation between foot, foot-model and orthotic frame when different methods are combined. Congruent accuracy is a measure of how closely the orthotic frame matches the patient’s foot in the exact position the patient’s foot impression was captured.

Indicate in special instructions if specific Fabrication Method is desired. Account standards can be set up by emailing hello@kevinrootmedical.com.

Foot Impression and Frame Fabrication Method Outcome Variation Chart

* Because the redimold method has no physical or digital foot impression, the congruent accuracy from patient foot to cast is unavailable. However, the congruent accuracy from positive model to vacuum formed frame has a low degree of variation.

Standard Lab Methods for Frame Fabrication and Foot Model Data Storage

* Requests to change standard frame fabrication methods and foot model data are welcome. To change a clinician’s fabrication and foot model data storage methods contact hello@kevinrootmedical.com

If plaster slipper cast, impression foam cast or STS slipper socks foot impression method is used, the foot model data storage can be selected per order.

Store plaster positive mold for 3 months (lab standard): If requested, the storage of plaster positive molds will be held for 3 months if modifications or additional pairs are needed.

Digitize my impression: KevinRoot Medical will use a 3D method to create a digital positive model which is stored indefinitely and can be recalled for fabricating consistent orthotics.

Note on Digitizing Positive Models: If a positive plaster model is digitized, KevinRoot Medical cannot guarantee replicating the exact and intimate contours that were vacuum formed over the positive plaster model previously.
Note on Digitizing Deep Heel Cups and Flanges: For very deep heel cups, medial and lateral flanges, such as UCBL devices, digitizing impressions or using digital fabrication methods are not recommended.

Return positive model: Positive models can also be returned with the orthotic devices and patients can be responsible for storage if future pairs or modifications are needed.
