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.
Interventions
DEVICEskeletal anchorage and rapid palatal expansion
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.
