Two-point rapid palatal expansion: an alternate approach to traditional treatment.

Abstract:

:Rapid palatal expansion (RPE) causes separation of the lateral halves of the palate and traditionally has used four maxillary teeth as anchorage. The purpose of this study was to introduce a rapid palatal expander that requires only two anchor teeth (two-point RPEe) and to compare the expansion obtained with that from a Hyrax appliance. This study involved two groups of 25 children aged 7 to 15 years who were treated in a private orthodontist's office with either a Hyrax appliance or a two-point RPEe. Dental casts and occlusal radiographs were made before treatment and at least three months after stabilization of the appliance. Paired t-tests were performed to identify significant intragroup changes, and independent t-tests were performed to determine intergroup differences. The findings showed the two-point RPEe was as efficient as the Hyrax in obtaining dental expansion of the maxillary posterior teeth with less effect on the maxillary anterior and mandibular teeth. Therefore, the two-point RPEe may be useful in certain clinical situations.
