Introduction:
The Carriere Motion 3D appliance (CMA) is gaining popularity for the correction of Class II dentoalveolar relationships. Recently, Gilad's Modified Corrector (GMC), a simple, "do-it-yourself" alternative, was introduced. This study evaluated the effectiveness of the GMC in treating Class II malocclusions and compared it with the CMA.
Methods:
A retrospective comparative analysis was conducted on 42 adolescent patients: 21 were treated using the GMC and 21 using the CMA. Cephalometric radiographs were taken pretreatment and after achieving a Class I posterior relationship. They were analyzed, and statistical comparisons were made between the 2 groups.
Results:
Both appliances effectively corrected the Class II molar relationship. The changes were primarily dentoalveolar in nature. The maxillary first molar was distalized, tipped distally, and also derotated by the 2 appliances. Both appliances mesialized the mandibular dentition, causing minimal proclination and protrusion of the mandibular incisors. The treatment duration was comparable for both groups.
Conclusions:
The GMC and CMA effectively correct Class II malocclusions probably through similar mechanisms. The GMC appliance may offer a practical alternative to the CMA.
