Abstract

Generally, a canted occlusal plane results in esthetic problems, such as an asymmetric mandible with midline deviation, and functional problems, such as temporomandibular disorder (TMD). For many years, orthognathic surgery has been used to level a canted occlusal plane. However, similar effects might be achieved by intruding the posterior teeth using a miniscrew. This case report describes a patient with a canted occlusal plane, mandibular deviation, shifted dental midlines, and TMD treated with an edgewise appliance using miniscrews as anchorage. Vertical control of posterior teeth with miniscrews enabled flattening of the canted occlusal plane. Dental midlines were coincided with the midfacial line, thereby improving smile symmetry. During 4 years of retention, the patient maintained ideal occlusion. Furthermore, TMD symptoms disappeared, and significant improvements in stomatognathic functions were observed compared with those at pretreatment. These results suggest that miniscrews can be used to improve canted occlusal plane and stomatognathic malfunctions.
