Abstract

Introduction: This case report describes compensatory orthodontic treatment in a young patient aged 13 years. She presented with a class III skeletal malocclusion associated with mandibular laterognathy. The patient's main reason for consultation was the anterior cross bite and the aesthetics of her smile.
Materials and Methods: The chosen treatment was therefore an orthodontic camouflage with the extraction of the first mandibular premolars and the second maxillary premolars, in order to catch a correct anterior articular and restore a good occlusal relationship, however, the mandibular laterognathy was camouflaged by means of dental compensations and also by correcting the deviation of the incisors medians through a class III mechanics with good anchorage management.
Results: After 24 months of treatment, an ideal overjet and overbite associated with a Class I canine and molar relationship, was obtained, associated with a perfect coincidence of the interincisor medians.
Conclusion: Class III skeletal cases can often be treated either by orthodontic camouflage or surgery. In our case study, the treatment adopted was orthodontic camouflage with extractions. The results of the treatment were satisfactory and the occlusal objectives were achieved. The final harmonious smile pleased the patient and improved her self-esteem and quality of life.
