Treatment of Skeletal Class III Malocclusion Using Orthodontic Removable Traction Appliance
Class III Malocclusion
About this trial
This is an interventional treatment trial for Class III Malocclusion focused on measuring Class III treatment, orthodontic removable traction appliance, RCT
Eligibility Criteria
Inclusion Criteria:
- Patients in early mixed dentation (8-10 years old).
- Skeletal class III caused by maxillary deficiency with or without mandibular prognathism judged clinically and confirmed radiographically(ANB≤1).
- Anterior crossbite on two teeth or more or an edge-to-edge bite.
- Normal inclination of the lower incisors with the mandibular plane.
Exclusion Criteria:
- Poor oral hygiene.
- Previous orthodontic treatment.
- Patients with syndromes, clefts, or craniofacial abnormalities.
- Severe skeletal class III primarily resulting from mandibular prognathism (ANB less than - 4)

Arm 2
Experimental
No Intervention
orthodontic removable traction appliance
Control group
Patients in this group will be treated using the orthodontic removable traction appliance (vacuum plate with two hooks between lateral incisor and canine in each side). An rapid maxillary expander will be applied to disarticulate maxillary sutures to allow more efficient forward protraction of the maxilla. Class III elastic traction from upper first molar to the hook in both side. This appliance will be used full-time with Class III elastics (6- to 8-ounce) traction.
