Dentofacial Effects Of Two Non-Compliance Appliances In The Treatment Of Growing Skeletal Class III Patients

Malocclusion, Angle Class III Clinical Trial

Official title: Three Dimensional Evaluation Of Dentofacial Effects Of Two Non-Compliance Appliances In The Treatment Of Growing Skeletal Class III Patients (A Randomized Controlled Clinical Trial)

Status Completed

Clinical Trial 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.

Clinical Trial Description

Aim of the work: Evaluate the skeletal, dentoalveolar and soft tissue effects of two different force application systems which are the pulling force (CS 2000® appliance/ CS appliance) and the pushing force (Reversed Forsus fatigue-resistant device/ RF appliance). Materials and methods: A randomized controlled clinical trial will be conducted to address the aim of the study. Thirty three growing skeletal Class III patients (9-11 years) will be recruited upon a lateral cephalometric x-ray. Subjects complying with the inclusion criteria will be randomly assigned using a computer-generated list to one of the three groups Group I: Eleven patients treated with CS2000 appliance, Group II: Eleven patients treated with reversed Forsus Fatigue Resistant device and Group III: control group of Eleven untreated patients with a ratio of 1:1:1 allocation. A CBCT will be made before installing the appliances. After gaining a 2 mm positive overjet or a 6 months period, alginate impressions will be poured and dental casts will be made. Photographs and CBCTs will also be performed to record the dentofacial effect of the used appliances.
