The Effects of Various Rapid Palatal Expansion Appliances on Dentoskeletal, Dentoalveolar, Nasal and Airway Resistance: A Prospective, Randomized Controlled Trial
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Full Coverage Rapid Palatal Expansion (FCRPE) group:
Impressions were taken from the maxilla using alginate to obtain study models.
In the obtained study model, a 10 mm hyrax expansion screw (Dentarum®, Germany) was placed at the midline as close to the palate as possible and parallel to the occlusal plane.
The vestibular, occlusal, and palatal surfaces of all maxillary teeth are covered in acrylic, and this acrylic support extends toward the median palatal suture in the palatal region.
Under pressure, the acrylic appliance was polymerized.
|
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.
|
Active Comparator: Modified McNamara Rapid Palatal Expansion (MMRPE) Group:
Impressions were taken from the maxilla using alginate to obtain study models.
In the obtained study model, a 10 mm hyrax expansion screw (Dentarum®, Germany) was placed at the midline as close to the palate as possible and parallel to the occlusal plane.
The vestibular, occlusal, and palatal surfaces of the posterior maxillary teeth are covered in acrylic, and this acrylic support extends toward the median palatal suture in the palatal region.
Under pressure, the acrylic appliance was polymerized.
|
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.
|
Active Comparator: Miniimplant Assisted Rapid Palatal Expansion (MARPE) Group
The MARPE appliance was composed of a central expansion jackscrew (Dentarum), 4 tubes, 2 bands on the upper first molars to facilitate placement of the appliance, and 1.5-mm diameter stainless steel arms extending to the premolar teeth.
Soldered stainless steel tubes (internal diameter: 2.0 mm; external diameter: 3.0 mm; length: 2.0 mm) served as guides for miniscrew placement.
The size of the screws (PSM) was chosen as 1.8 mm in diameter and 11 mm in length, considering the 2 mm height of the tubes, 1 to 2 mm gap between the appliance and the palate surface, 1 to 2 mm gingiva thickness, and 5 to 6 mm length required for the bicortical placement of the screw in the bone.
|
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.
|
No Intervention: Control Group
A control group in the same age, without maxillary constriction was also added to our study.Polygraphy for respiratory evaluation, rhinomanometry for nasal airway resistance were used.
Polygraphy and rhinomanometry measurements were obtained at the beginning of the follow-up and at the end of the 4-month follow-up period.
