简要总结
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.
详细描述
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.
