Abstract

Supraerupted maxillary molars usually result from early loss of the opposing mandible molars. This may induce insufficient intermaxillary space and compromised prosthesis. The best way to deal with supraerupted maxillary molars is no doubt to intrude them. For the minor supraeruption of maxillary molars, simply wearing a posterior bite plate could apply vertical force to intrude them. But the larger supraeruption, combination with temporary anchorage device usage will supply more stable anchorage force to intrude maxillary molars back to the normal position. This article reported three cases, one using only posterior bite plate and the others in combination with mini-screw, that all achieved the perfect treatment results.
