Summary

This randomized controlled trial intends to test the efficacy of two treatment protocols in the correction of Class III malocclusion with maxillary constriction. We have to options, either to modify the growth using inter-maxillary traction based on an upper fixed appliance that is used in the same time for rapid maxillary expansion or to inhibit mandibular growth by a removable mandibular retractor (RMR) supplied with an expansion screw.

Conditions

• Class III Malocclusion

Interventions

Type	Name	Description
DEVICE	RMR+SME	Patients will be asked to wear this removable appliance for 16 hours daily. The expansion screw is activated twice a week.
DEVICE	BAIMT+RME	The elastics are worn 18 hours per day to achieve the sagittal correction. The RME appliance on the upper jaw is activated twice daily until the required expansion is achieved.
