anterior repositioning splint
The anterior repositioning splint is an appliance used on the top teeth and has a sloping ramp to encourage the mandible (bottom jaw) to come forward in hope of recapturing an anteriorly displaced disc. The acrylic ramp rests lingual to the lower anteriors, with buccal and incisal indices of the lower cusp tips. This splint brings the mandible into a protrusive (forward) position. The splint is most commonly used at night because it keeps the mandible forward during sleep, when it would otherwise tend to relax and drop backwards.
Rationale
- To maintain or stabilize a stable jaw position
- Reduce a TMJ click
- Decompress the TMJ Disc
Construction requirements
- Upper and lower impressions
- Bite registration in a protrusive position
Further Information
The Anterior Repositioning Splint is also known as: the anti-retrusion appliance, pull forward splint, Farrar splint or ARS.
