Brief Summary

Early orthodontic treatment of Class III malocclusions with skeletal and dentoalveolar imbalances, represents a continuous dilemma. This difficulty starts from their meticulous diagnosis and treatment planning till reaching satisfactory results and finally stability. Some appliances could be used to correct growing skeletal Class III patients, improving the skeletal and dentoalveolar relationships, creating proper conditions for final orthodontic treatment, more importantly avoiding surgery. These appliances remove patient compliance from the equation.

Control

NO INTERVENTION

A group of untreated skeletally growing class III patients will be recruited to account for the possible effects of growth in the treatment groups. This group matches the treated groups in malocclusion, stages of skeletal maturation, and mean observation period. Those patients will be treated after the period of the study.

Eligibility Criteria

Age8 Years - 11 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Age range from 8 years to 11 years.
  • Cervical vertebrae maturation index (CVMI 2 and 3) identified on the lateral cephalometric radiograph.
  • Angle Class III molar relation.
  • Skeletal class III ANB ranges between (-4) - (0).
