Summary
<p>Aim of this study was to evaluate skeletal, dentoalveolar, sutural effects of miniscrew-assisted rapid palatal expansion (MARPE) in young adults using three-dimensional cone-beam computed tomography (CBCT). Treatment-related changes between female and male individuals were compared. Total of 15 young adult patients (7 females, 8 males) were included in the study. All patients were treated with bone-borne MARPE appliance supported by four miniscrews positioned in the anterior T-zone region. CBCT records obtained before treatment (T0) and after expansion (T1) were analyzed for transverse skeletal, dentoalveolar, periodontal, and sutural measurements. Measurement reliability was assessed using the ICC (3,1) model. Paired t-tests were used for intragroup comparisons, while independent sample t-tests were used for intergroup comparisons according to sex. Measurement reliability was excellent, with ICC values ranging from 0.994 to 1.000. Significant increases were observed in NW, MW, OFW, PMW, BMW, and ANCW measurements after treatment (p<0.05). Significant increases were also detected in midpalatal suture opening and nasal floor dimensions (SOANS, SO(M), SOPNS, NF, PF; p<0.001). Most dentoalveolar measurements did not show significant changes, indicating limited periodontal and dentoalveolar side effects. Although no significant sex-related differences were observed in most parameters, significant differences were found for PMW(1PM), NF, UXL-PL, UXL-PR, and DTR(1M) measurements (p<0.05). MARPE treatment produced substantial skeletal expansion with limited dentoalveolar side effects in young adults. Significant expansion at the midpalatal suture and nasal floor levels demonstrated that MARPE can provide effective transverse correction without surgical assistance. MARPE may be considered a reliable and effective treatment alternative for young adult patients.</p>
