Abstract

In growing patients with Class III malocclusion and midfacial deficiency, the treatment protocol calls for orthopedic maxillary protraction and clinicians choose the facemask therapy generally. But facemask is not esthetic or comfortable to patients because it should be worn extraorally. Consequently it is difficult to obtain patients cooperation, and this often influences the treatment effects negatively. MTA (modified tandem appliance), that is a small intraoral appliance, is carried conveniently and esthetic relatively. So it seemed more patient-friendly than a facemask. While the treatment effect of this is similar to that of a facemask. This report presents skeletal Class III malocclusion two cases treated by MTA with good results.
