CLASS III MALOCCLUSION TREATMENT WITH MAXILLARY EXPANSION AND FACE MASK COMBINATION: A CASE REPORT
The aim of this case report is to present the treatment of a female patient with skeletal Class III malocclusion due to maxillary deficiency and negative overjet using a functional appliance. A 12-year 4-month old female patient applied for treatment to our clinic with a chief complaint of the position of her anterior teeth. The radiographic and clinical examinations and evaluations showed skeletal class III anomalies and absence of lateral maxillary incisor bilaterally. Initially, maxillary expansion was provided to mobilize the maxillary sutures and then facemask was worn to improve the sagittal skeletal relation. Fixed orthodontic appliances were placed to align the dentition and Class III elastics were used to establish intercuspation and stability. A case with a skeletal class III malocclusion and negative overjet was treated in 2 years and 2 months in total, and class I canine relationship with normal overjet and good occlusion were achieved.
