Flat Plane Splint

The Flat Plane Splint may be used as an orthodontic diagnostic tool or treatment appliance.

Since it does not index or attempt to lock in the opposing arch, the Flat Plane Splint is well-suited to cases requiring a free mandibular position. Specialty Appliances fabricates it with flat occlusal acrylic designed for the upper or lower arch.

Bracket/Hardware Removal


  • Specialty Appliance's standard when fabricating splints for patients in active orthodontic treatment is to NOT remove brackets or other hardware prior to fabrication.
  • If we should deviate from this standard, please include a note on the prescription sheet specifying that we remove brackets/hardware before fabrication, and we will be happy to do so.
