Comparison between two bone anchored force systems for correction of skeletal Class II malocclusion in growing patients: a randomized controlled clinical trial, part 1: short-term skeletal changes.

ABSTRACT:

Objectives

To compare the treatment effects of pushing or pulling force mechanics applied to bimaxillary miniplates with those of deferred treatment control patients to evaluate mandibular skeletal growth changes in growing patients with skeletal Class II malocclusion due to mandibular deficiency.

Materials and methods

Thirty-nine patients (24 males, 15 females; mean age = 11.59 ± 0.56 years) were equally and randomly assigned to one of three groups: Group A, skeletally anchored fixed-functional appliance (pushing mechanics); Group B, skeletally anchored Class II spring (pulling mechanics); and Group C, deferred treatment skeletal Class II control patients. Pretreatment and posttreatment cone-beam computed tomography scans were used for assessment of measurements (time inter
