A functional maxillary wraparound retainer.

JCO/FEBRUARY 2004 H retainers with Adams clasps or labial wires crossing the occlusion can create interferences that may lead to bruxism or disc displacement1-3 (Fig. 1). On the other hand, if a wraparound retainer is fabricated without crossover clasps, it is difficult to adapt the round wire closely enough to the anterior dentition to provide adequate mechanical retention, especially in patients with shallow palatal vaults, flat palatal rugae, or palatal tori. A modified maxillary wraparound retainer, as described in this article, solves both problems.
