The Witzig upper splint is a Phase 2 treatment splint and is used to support the joint while in its corrected position. It is worn when lower incisor removal is the chosen treatment method. A lower crowded incisor is removed and the remaining anterior teeth (cuspid to cuspid) are bracketed. The dentition is rounded into a smaller arch. This eliminates the incisal misguidance. Patients will find needed relief because it allows the mandible to stay in a forward, pain-free position.
