The Effects of Combined Treatment With Low-level Laser and Functional Appliances on the Correction of Class II Malocclusion: A Randomized Controlled Trial
The Effects of Combined Treatment With Low-level Laser and Functional Appliances on the Correction of Class II Malocclusion: A Randomized Controlled Trial
This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only.
The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group.
Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.
Class II malocclusion is considered as the most common malocclusion between patients.
Recently low-level laser enters the world of dentistry, some studies assessed the effect of low-level laser on the growth of mandibles and condyles in animals and showed that there is a good effect of laser on the mandible growth.
This study will evaluate the effect of low-level laser on the growth of the mandible and the duration of functional treatment.
Twin-block will be applied in two groups: The control group will receive the twin-block only, and the experimental group will receive the twin-block combined with low-level laser therapy on the TMG region.
Cephalometric radiographs will be gotten before and after functional treatment to evaluate the dento-skeletal changes.
