| Abstract Objective: To compare dental treatment results of using Mono and Bicortical Hybrid Hyrax appliances in late-adolescent patients using CBCT scans. Materials and Methods: A total of 16 patients, ages 18 to 21, who had maxillary skeletal crossbite, were chosen. They were then randomly assigned to have treatment with a monocortical hybrid hyrax or a bicortical hybrid hyrax appliance that used palatal miniscrews with either a monocortical or bicortical engagement. The digital method used to create the hybrid appliances combined CBCT and intraoral digital images, which were then used to position miniscrews virtually and create a surgical guide utilizing 3D printing. The activation techniques were the same for both groups. Every patient had CBCT scans both before and after therapy. These were employed to contrast dental outcomes. The Shapiro-Wilk Normality Test, Kolmogorov Test, and Paired T Test between the pre- and post-treatment outcomes were used to statistically assess the resultant data. Results: Transverse dental linear measurements was successful in both groups as there was no statical significance except, in M1 AW (mm) as Group I (3.16 ± 0.72) was significantly lower than Group II (5.48 ± 1.78) with (2.32 ± 0.68) difference as P=0.0001. Conclusions: Transverse interdental expansion was possible at the late-adolescent stage with Hybrid Hyrax appliances either mono or bicortical group. Expansion results were comparable in both groups. | ||||
