Orthodontics and Dentofacial Orthopedics


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. Thesepatients were treated simultaneously with the MARA appliance with skeletal anchorage for 16.5 months on average. Allthe patients had the following criteria: skeletal Class II due to mandibular retrusion, overjet more than 4mm, nosystemic diseases, no previous orthodontic treatment, or abnormal habits. Photographs and study casts were obtainedbefore and after treatment. Lateral head films were taken before MARA appliance treatment and after MARA applianceremoval. The collected data were analyzed using IBM SPSS software Version 22.0.Results: Restricted maxillarygrowth and significant mandibular growth were observed upon using the MARA appliance. Overjet was improved, andalso maxillary molar distalization, and improvement of soft tissue profile were observed. Conclusions: The MARAappliance 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 forthe correction of the Class II malocclusion.
