ClinConnect Summary

This research aimes to evaluate the effects of a Class III functional appliance \[the modified fixed mandibular retractor (MFMR)\] in the early treatment of skeletal Class III deformities.

It was not ethical to expose all candidate children to radiographic examination. Therefore, the assessment of skeletal Class III malocclusion was based on clinical judgment. Each patient was examined, while his/her mandible was kept at its retruded contact position to evaluate both jaws in space. Those who met the inclusion criteria were then sent to the radiographic department.
