Abstract

Objectives: The purpose of this study was to compare cephalometric changes resulting from treatment with two appliances for rapid maxillary expansion: (1) a strictly tooth-borne appliance and (2) a combined tooth- and bone-borne appliance.

Patients And Methods: Pre- and posttreatment lateral cephalograms of 100 patients were analyzed by cephalometry. Of these patients, 50 were treated with strictly tooth-borne and another 50 with combined tooth- and bone-borne appliances. Mean pretreatment age was 13.04 ± 4.82 years, and mean treatment duration was 7.12 ± 2.37 months. To identify any implications for clinical therapy, additional subgroups were formed based on the pretreatment cephalometric findings for skeletal Class I (0° < ANB ≤ 4°) or Class III (ANB ≤0°). Paired t-tests were used for intragroup and analysis of variance (ANOVA) for intergroup comparisons. Results were considered statistically significant at p ≤ 0.05.

Results: Both appliance types resulted in significant cephalometric changes in the maxilla and mandible. Compared to the strictly tooth-borne appliances, the combined tooth- and bone-borne appliances were found to cause more pronounced advancement of the maxilla (SNA angle) notably among the Class III patients.

Conclusions: Hybrid (combined tooth- and bone-borne) appliances for rapid maxillary expansion might be preferable in the treatment of skeletal Class III patients, since they possibly exert a more pronounced skeletal effect on the sagittal position of the maxilla.
