The Effects of Various Rapid Palatal Expansion Appliances on Dentoskeletal, Dentoalveolar, Nasal and Airway Resistance

Not Applicable
Completed
Conditions
Transverse Maxillary Deficiency
Registration Number
NCT06009796
Lead Sponsor
TC Erciyes University
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.
