Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type OTHER

skeletal anchorage and rapid palatal expansion

Intervention Type DEVICE

Eighteen patients were randomly divided into 2 groups through a free randomization program (Random Allocation Software 2.0). Baseline demographic characteristics were matched in both groups. All appliances were fabricated by the same technician in the orthodontic lab. All individuals were treated by a single practitioner.

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
