Correction of Skeletal Class III by Wunderer’s Activator and Face Mask
Journal Title: Indian Journal of Dental Advancements - Year 2017, Vol 9, Issue 4
Abstract
Context: Treatment of skeletal Class III malocclusion in growing patients is a challenging part of contemporary orthodontic practice. Many appliances are now available for correcting skeletal Class III malocclusion due to maxillary deficiency. In the current study, the Wunderer’s activator and face mask were used for the correction of skeletal Class III in growing patients to overcome the latter side effects of other appliances. Objective: Evaluation of dentoskeletal changes before and after growth modification by Wunderer’s activator and face mask. Materials and Methods: A total of 12 growing Class III subjects with maxillary retrusion in the early mixed or early permanent dentition (6 male and 6 female) were included in this study. The samples were treated by Wunderer’s activator and a face mask for 12 months. Lateral cephalometric tracings were done before and after correction to evaluate the efficacy of Wunderer’s activator and face mask. Result: The results showed a highly statistically significant increase in the sella-nasion A angle by 1.98° ( P < 0.001) and a statistically significant decrease in the sella-nasion B angle by −0.83° ( P < 0.001). Furthermore, the wits appraisal was found to be highly significant increased by 2.8 mm. The vertical measurements showed significant increase where the SN/occlusal plane (OCP) angle and the SN/Gonion-Gnathion angle where increased by 2.1° and 1.78°, respectively. The overjet and proclination maxillary incisors display were improved with retroclination of the lower incisors. Conclusion: Face mask and Wunderer’s activator were effective in the treatment of skeletal Class III malocclusion due to maxillary retrusion.
