Evaluating the Effectiveness of the Lower-Clear-Plate-Based Intermaxillary Traction

Hard- and Soft-tissue Changes Following Class III Treatment With the Lower-Clear-Plate-Based Intermaxillary Traction Versus the Removable Mandibular Retractor: a Two-arm Randomized Controlled Clinical Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional

• Sponsor: Damascus University · Academic / Other
• Sex: All
• Age: 9 Years – 13 Years
• Healthy volunteers: Not accepted

Summary

Patients at the Orthodontic Department of the University of Damascus Dental School will be examined, and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure the selection criteria are accurately matched. This study compares two groups of patients with mild to moderate skeletal Class III in the late mixed occlusion stage. Experimental group: the patients in this group will be treated with Lower-Clear-Plate Based Intermaxillary Traction Control group: the patients in this group will be treated using the Removable Mandibular Retractor (RMR).

Detailed description

There are different methods of correcting Class III deformity in Orthodontics. Lower-clear-plate-based intermaxillary traction has been shown to be an effective method of managing these cases. This treatment modality has not been compared with the well-known appliance (the removable mandibular retractor; RMR). Therefore, the current study compares both groups of growing children with Class III malocclusion. The study design is a randomized controlled trial.

Conditions

• Class III Malocclusion

Interventions

Type	Name	Description
DEVICE	lower-clear-plate-based intermaxillary traction (LCP-IMT)	The patient is instructed to apply elastics between the upper molar bands and the hooks on the lower clear plates.
DEVICE	Removable mandibular retractor (RMR)	An appliance is worn on the upper jaw, which affects the lower jaw by using an inferiorly extended labial bow.
