The technical operation of lingual orthodontic appliances using digital technology

Proposal for a direct printing method using a 3D printer to fabricate an in-direct core for a lingual orthodontic appliance.

Abstract

We introduce a method for designing setup and IDB trays to fabricate lingual orthodontic appliances in a digital environment. In addition, we report a build-in base technique that adds torque, angulation, and rotation to a resin base, which is difficult to achieve using conventional plaster casts.
