Study Overview
Brief Summary
This study aimed to investigate the skeletal, dentoalveolar, and periodontal changes of tooth-bone-borne (TBB) and bone-borne (BB) appliances with identical miniscrew placement using cone-beam computed tomography (CBCT) in the post-pubertal growth spurt stage.
Detailed Description
Eighteen patients were divided into 2 groups: TBB group (n = 9, 16.11 ± 0.59 years of age) and BB group (n = 9, 15.33 ± 1.22 years of age). CBCT scans were obtained before treatment and after 3 months of expansion. Transverse skeletal and dental expansion, alveolar and tooth inclination, and buccal alveolar bone thickness were evaluated in maxillary first premolars and molars. Paired t tests and independent-sample t tests were used to compare the expansion appliances.

Arms & Interventions
tooth-bone-borne (TBB) group
The TBB 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.
Intervention: skeletal anchorage and rapid palatal expansion (Device)
bone-borne (BB) group
The BB appliance was composed of a central expansion jackscrew, 4 tubes as described in TBB group, and less acrylic used around it to adjust its position. In order to carry it to the mouth after preparation on the cast model, essix was used, which also included the patient's teeth
Intervention: skeletal anchorage and rapid palatal expansion (Device)
