Custom Brim Shapes  

What Are Custom Brims?

Custom brims are a custom shape of a limb to use as a base for fabricating either an AK by numbers socket or a Scan Merged Socket that is different than our Standard Brims. 

Use a custom brim by selecting “Clinic Custom” in the Brim Shape dropdown in the order form. If you have multiple custom brims, specify which one to use in the additional information section.

How to Submit a Custom Brim

There are two main ways to design a custom brim. First, for the best results, scan and submit a plaster positive from a socket with the desired brim shape. Mark landmarks like the perineum to help align the brim with your measurements. Second, we can modify one of our standard brims.

Scan of a Plaster Positive:

1. Submit through FabOne Above Knee Order Form
   1. Upload your scan of your custom brim to FabOne
   2. Log in → Go to AK Socket order form → Select the scan of the custom brim → Fill out the order form.
   3. In the AK Brim shape drop-down, select “Clinic Custom” to indicate use of this brim for the current patient.
   4. In the “Additional Information” section (bottom of the order form), note that this brim should also be saved as your or “Clinic” custom brim for future use. If you plan to have multiple custom brims, tell us what to name each for future reference.
   5. We’ll save your brim to our system and your profile for the future as well as make the order based on that shape
   6. You may submit a scan for use as a custom brim using the order form without having it designed into a patient’s socket. Note this in the additional information and the order will be removed after the design lead has received it, so it isn’t counted in your allotted designs per month.
2. Email
   1. Scan the plaster positive you’d like to make into a brim.
   2. Send scan directly to [success@protosthetics.com].
   3. Specify if the custom brim should be used for future orders.

Modify an existing standard brim

1. Submit through FabOne order form
   1. Ask us on a real order to make adjustments to a brim we use in the additional information section.
   2. In the comments just ask for this modification to be added to your custom brims.
   3. If you plan on having multiple custom brims, tell us what to name this brim for future reference.
2. Submit through a quick revision
   1. Submit a revision to an AK order and just ask us to make that order your custom brim.
   2. You’ll receive a confirmation message from us and the order will be removed after the design lead has received it, so that it doesn’t count against one of your allotted designs.
   3. If you plan on having multiple custom brims, tell us what to name this brim for future reference.
