TF Design is a software solution for the custom design of check sockets, providing an outstanding alternative to the classic plaster cast technique.

All socket shapes were developed based on clinically proven knowledge and our experts’ many years of expertise. The default design options allow for quick training and provide support where socket design is concerned. This makes TF Design a great starting point for digitalisation.

The latest version of the software offers you improved socket models as well as patches that are usefully positioned from a biomechanical perspective to improve your treatment results.
