Upper Anterior Repositioning

The anterior repositioning splint (also referred to as the anti-retrusion, pull forward, or Farrar splint) is used to recapture an anteriorly displaced disc. A definite click in the joint is present. This is a full-coverage maxillary splint with an acrylic flange that rests lingual to the lower anterior teeth, with buccal and incisal indices of the lower cusp tips. This splint brings the mandible into a protrusive position. The anterior repositioning splint is most effective at night because it keeps the mandible forward during sleep when it would otherwise tend to relax and retrude.

Treatment & Care

Upper splint position is maintained by an acrylic flange, which rests lingual to the lower anterior, and indexes the lower buccal cusps. Flange holds its position even at night when the jaw relaxes. Lower splint maintains position with deep buccal, lingual, and incisal indexing of the upper cusp tips.

Patients should wear at night and clean daily with toothpaste to prevent the buildup of plaque and odor. Avoid Efferdent and other effervescent solutions, as it may erode components on the appliance. It is recommended to use products like Dent Soak or Retainer Splash.
