Skeletal Malocclusion Clinical Trial
Official title:
Cephalometric Evaluation of a Clear Mandibular Advancement Appliance Based on the Twin-block Design
This study evaluates the cephalometric effects of a clear mandibular advancement appliance for the treatment of skeletal class II growing patients suffering from mandibular deficiency.
A Clear mandibular advancement appliance is constructed comprised of a clear dental splint of 1.5 mm thickness adapted on the patient's teeth. This is followed by the construction of acrylic bite ramps bonded over the splints. The bite ramps are constructed as such when the patient bites into occlusion, he/she has to advance the mandible to bring the two parts of the appliance together. Lateral cephalometric radiographs were obtained pre and post-treatment to evaluate the effects on the patient's maxilla, mandible and dentition. ;
