Camouflage of Class III Malocclusion by the Maxillary Protrusion and Retrusion Of The Mandible Using a Removable Functional Appliance Model: Case Report

Abstract

The objective of this case report was to present the camouflage of class III malocclusion with functional forces using a type 4 morpho-functional inducer. Methods: The patient was a 10-year-old Latin girl. Patient in front and profile was carried out. The position of the left and right superciliary arches, the position of the orbital cavities, and the position of both labial corners were evaluated. Similarly, the type of profile of the patient, the degree of concavity, the position of the lower lip concerning the upper lip, and the position of the chin concerning the nose and forehead were evaluated. In the lateral cephalometric analysis, the sagittal position of the maxilla and mandibular was evaluated through the SNA and SNB angles as well as the level of discrepancy obtained by the ANB angle. SNA before treatment was 79 degrees and SNB 87 and ANB -3 Results: after treatment, the SNA angle varied to 86 degrees, the SNB to 84, and ANB to 3 degrees. The linear measurement between the projection of points A and B to the Frankfort plane before treatment was - 2mm and after + 2 mm. The incisive angles changed to camouflage. The upper incisor angle before treatment was 122 degrees and after 118. The lower incisor angle before treatment was 96 degrees and suffered a decrease of 1 degree. Conclusion: The treatment of class III in skeletal using morpho-functional inducers in well-diagnosed cases and young patients is an alternative that allows obtaining favorable results that allow avoiding surgery.
