Abstract :The purpose of this study was to evaluate volumetric differences of the maxillary sinus on computed tomography data taken before RME, after 3 months of retention and 1 year following retention. Twenty one consequtive patients insert ignore into journalissuearticles values(11 girls, 10 boys ); who required RME with cap splint Hyrax appliances as part of their orthodontic treatment were studied. Volumetric measurements before insert ignore into journalissuearticles values(T1);, after retention period insert ignore into journalissuearticles values(T2); and one year following the retention period insert ignore into journalissuearticles values(T3); of RME were performed using a 3D tomography prototyping software insert ignore into journalissuearticles values(Mimics v.14.0, Materialise, Belgium);. Maxillary sinus regions were isolated in every slice and then the 3D images were constituted. Sinus volumes were measured. The acquired data were compared for three periods by using repeated measures ANOVA and post-hoc comparisons were made by paired samples t-test. In the volumetric evaluation of maxillary sinuses in RME patients, sinus volume increase was statistically significant in all three times insert ignore into journalissuearticles values(P<0.001);.
