The effect of tongue appliance on the maxilla in Class III malocclusion due to maxillary deficiency.
Various treatment approaches are applied for correction of CL III malocclusion due to maxillary deficiency. However, the benefits of a simple intraoral appliance that can move the maxilla in forward position have not been reported. 25 Cl III patients with SNA < 78 degrees, SNB < or = 80 degrees and ANB < or = 0 were selected for this study. All the patients received a tongue appliance, which originally was a habit breaker. Pre- and post-treatment cephalometric images were obtained and paired t-test revealed significant increase in SNA and significant decrease in IMPA. The tongue appliance can move the Maxilla in forward position. Therefore, this simple appliance can be an alternative method for protraction of Maxilla.
