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.

Conditions

• Transverse Maxillary Deficiency

Interventions

Type	Name	Description
DEVICE	Tooth Tissue Borne Rapid Palatal Expansion	In all rapid palatal expansion groups, the appliances were cis bonded after being made by the same technician. The expansion screw was turned twice a day until the desired width was achieved.
DEVICE	Tooth Bone Borne Rapid Palatal Expansion	After the Marpe appliance was attached, 4 miniscrews were applied to the midline of the palate with a miniscrew driver. The expansion screw was turned twice a day until the desired width was achieved.
