No results posted yet for this study

Summary

This in vivo comparative study will evaluate the changes in the mandibular dimensions and the glenoid fossa after skeletal class III subjects' therapy by chincup appliance and compare it with an untreated class III control group. Pre and post-treatment low-dose computed tomography images will be taken before and after achieving positive overjet and undergoing 16 months of active treatment/ observation. Dimensional and volumetric changes in the mandible, condyles, and glenoid fossa will be calculated and compared to those observed in the control group.

Conditions

  • Class III Malocclusion

Interventions

DEVICE

Chincup

Patients will receive an individual fabricated bonded bite block and occipital chincup. A 400-500g/side retroactive force will be applied in the direction of the condyles. Patients or panthers will be instructed to wear the appliance /14-16/ hours a day.

OTHER

Control group

The changes in condyle-mandibular volumes and superficial areas and relative positions of the condyles and glenoid fossa will be calculated after 16 months of observation.
