Assessment of dental changes after rapid maxillary expansion

Objective: This study aimed to evaluate the angle of pre transverse projection and after rapid maxillary expansion (RME) in central incisors and first molars. Methods: They were assessed by computed tomography (CT) 30 patients in the existing database, aged 7 and 14 years of both sexes (mean age of 9.7 years Patients were treated with breaker banded Hyrax type and activations were monitored and completed after the cross-compatibility of the upper bone base with Wala edge of the lower basal bone. patients underwent tests pre-expansion computed tomography (T1) and after 3 months ended expansion (T2) respecting the ALARA index. Data were coleados through the OsiriX imaging program. We evaluated two dental structures, central incisor and First Molar Permanent Superior, which evaluated the degree of tilt after RME. We evaluations of individual changes, intra-group, inter-group. Results: the result after comparing the data showed that almost all suffered no significant changes except ANGLE INCISOR in 6 PALATE 6 RIGTH and 6 PRSPs 6 LEFT. Conclusion: in short-term changes occur in the direction of the long axis of the molars and maxillary central incisors after RME.
