Overview
Brief Summary
This study aims to evaluate the effects of dentoalveolar, dentoskeletal, nasal resistance, and airway changes by applying rapid palatal expansion appliances in patients with maxillary constriction and the post-pubertal growth spurt stage.
Detailed Description
Fifty eight patients were divided into 4 groups. The first group (n: 15, 15.6 ± 1,1 years of age) was Full Coverage Rapid Palatal Expansion (FCRPE). The second group ( n:14, 15.3 ± 0,9 years of age) was Modified McNamara Rapid Palatal Expansion (MMRPE). The third group (n:14, 15.7 ± 1,1 years of age) was Miniimplant Assisted Rapid Palatal Expansion (MARPE). The fourth group (n:15, 15.4 ± 1,0 years of age) was control group. Polygraphy for respiratory evaluation, rhinomanometry for nasal airway resistance, study model, and posteroanterior radiographs (PA) to measure dentoalveolar and dentoskeletal effects were used. Respiratory polygraphy, rhinomanometry, study model, and posteroanterior radiographs were obtained prior to treatment and after 3 months of expansion. Paired t tests and independent-sample t tests were used to compare the expansion appliances.
