The anterior repositioning 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 anteriors, 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.
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 DentaSoak or Retainer Splash.
