Surgical Orthodontic Treatment Of Skeletal Class Iii Facial Asymmetry

ABSTRACT When considering camouflage orthodontic treatment for Class III malocclusion with skeletal facial asymmetry, it is crucial to preserve the favorable compensated posterior occlusion. Once the inclination of the compensated occlusion is changed during orthodontic treatment, unstable occlusion, such as crossbite or scissor bite may occur. A 23-year-old female patient had anterior spacing with Class III malocclusion and a mandibular asymmetry. A nonsurgical approach was adopted. The treatment objectives were to establish a Class I molar relationship with compensated inclination of the posterior dentition and to correct the midline deviation. To achieve these goals, the computer-aided design/computer-aided manufacturing (CAD/CAM) orthodontic system plus customized brackets was applied, and miniscrews were used to distalize the left mandibular dentition for midline correction. The results suggested that the CAD/CAM-based customized brackets can be efficiently used in camouflage treatment to achieve a correct final occlusion.

ABSTRACT Class III malocclusion with facial asymmetry is difficult to treat with orthodontic treatment without surgery. Skeletal class III malocclusion can be treated with surgery or orthodontic treatment by camouflage. Functional class III malocclusion can be treated perfectly by orthodontic treatment, using the intermaxillary elastics (IME) to correct the jaw relation. Differentially, diagnosing a class III case is important before deciding the treatment plan. We must understand the type of class III malocclusion and then we can make the best choice for the patient. This article reports the treatment of adult class III malocclusion by the improved superelastic TiNi alloy wire (ISW). Using the ISW crossbite arch, coil springs and IME, adequate overbite and overjet were achieved and better facial symmetry was also improved. How to cite this article SUN Cb, YU Jh.

INTRODUCTION: Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention of tooth #53, tendency to vertical growth of the face and facial asymmetry. The discrepancy on the upper arch was -2.0 mm and -5.0 mm on the lower arch. METHODS: The pre-surgical orthodontic treatment was performed with extractions of the teeth #35 and #45. On the upper arch, teeth #53, #12 and supernumerary were extracted to accomplish the traction of the impacted canine. The spaces of the lower extractions were closed with mesialization of posterior segment. After aligning and leveling the teeth, extractions spaces closure and correct positioning of teeth on the bone bases, the correct intercuspation of the dental arch, with molars and canines in Angle's Class I, coincident midline, normal overjet and overbite and ideal torques, were evaluated through study models. The patient was submitted to orthognathic surgery and then the post-surgical orthodontic treatment was finished. RESULTS: The Class III malocclusion was treated establishing occlusal and facial normal standards.
