Objective: to study the effects of treatment of Forsus device supported with miniscrew and evaluate them against those of the Carriere Motion 3D Appliance (CMA).
Materials and Methods: Treatment records of 38 patients diagnosed with Class II malocclusion who underwent treatment with the miniscrew anchored Forsus device or Carriere Motion 3D Appliance were collected. Group I (12.78±1.7 years): A total of 19 patients, consisting of 11 girls and 8 boys, had treatment with a miniscrew-anchored Forsus. Group II (13.01±1.5 years): A total of 10 girls and boys males had treatment using a Carriere Motion 3D Appliance. Lateral cephalograms were measured linearly and angularly both before (T1) and after (T2) appliance installation and removal, respectively. independent t-tests were used to analyze differences between groups, while paired t-tests were employed to evaluate changes within groups.
Results: Both groups showed significant reductions in SNA and ANB angles, while SNB remained unchanged. LFH increased significantly in both groups. Group I showed significant retraction of maxillary incisors, whereas Group II demonstrated significantly more protraction of mandibular incisors. Both groups demonstrated significant reduction in overjet and overbite. Additionally, Group II showed significantly more distalization of the maxillary first molar compared to Group I.
Conclusion: Both miniscrew-anchored Forsus and CMA are effective and efficient approaches for correcting Class II malocclusion. CMA showed less retraction of maxillary incisors than miniscrew anchored Forsus. Significant protraction of the mandibular incisors in CMA could lead to an early correction of the overjet, which could subsequently restrict skeletal correction.
