| Objective: To investigate the effects of the fixed functional appliance Mandibular Anterior Repositioning Appliance (MARA) with skeletal anchorage on growing patients with skeletal Class II malocclusion. Materials and Methods: This study was conducted on 10 patients with a mean age of 10.3 years with skeletal Class II malocclusion. These patients were treated simultaneously with the MARA appliance with skeletal anchorage for 16.5 months on average. All the patients had the following criteria: skeletal Class II due to mandibular retrusion, overjet more than 4mm, no systemic diseases, no previous orthodontic treatment, or abnormal habits. Photographs and study casts were obtained before and after treatment. Lateral head films were taken before MARA appliance treatment and after MARA appliance removal. The collected data were analyzed using IBM SPSS software Version 22.0.Results: Restricted maxillary growth and significant mandibular growth were observed upon using the MARA appliance. Overjet was improved, and also maxillary molar distalization, and improvement of soft tissue profile were observed. Conclusions: The MARA appliance was effective in the treatment of Class II malocclusion by a combination of slight skeletal and dental changes. Restriction of maxillary growth and dentoalveolar changes in the maxillary and mandibular arches were responsible for the correction of the Class II malocclusion. | ||||
