Changes in anteroposterior position and inclination of the maxillary incisors after surgical-orthodontic treatment of skeletal class III malocclusions

Basal cell nevus syndrome (BCNS) is a rare genetic disorder that can be caused by mutation of multiple genes, including PTCH1, PTCH2, and SUFU, in an autosomal dominant manner. The symptoms include some craniofacial features such as keratocystic odontogenic tumors (KCOTs), macrocephaly, and cleft lip and/or palate. Although comprehensive orthodontic treatment is frequently required for some of these craniofacial deformities, there are few reports that show the outcomes of comprehensive orthodontic treatment. Here, we report a case of BCNS with multiple KCOTs, macrocephaly, skeletal class III malocclusion, asymmetric dental arch, and mandibular crowding, which was successfully treated with comprehensive orthodontic treatment.

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.

Relevance. Skeletal Class III malocclusion is one of the most difficult to correct. Genetics, environmental factors, and postembryonic development influence its etiology. Sagittal expansion of the upper jaw will ensure the correct position of the lower jaw, which in turn will improve the patient's aesthetic parameters and health. The study examines a treatment method using the Fixed anterior growth guidance appliance (FAGGA).Materials and methods. This clinical case presents a 21-year-old male with skeletal class III due to maxillary bone deficiency. The patient refused surgery to increase the size of the upper jaw and opted for orthodontic treatment. The latter was performed using a Fixed anterior growth guidance appliance (FAGGA), followed by a rapid palatal (maxillary) expansion (RME) and brackets. We removed the FAGGA after eight months. The profile and occlusion improved.Results. The change in the inclination and protrusion of the maxillary incisors improved the profile. We received 2mm of space behind the upper right canine and 1.5mm of space behind the left one and the SNA angle increased by 2 degrees. The treatment continues with RME and brackets.Conclusions. An increase in inclination and protrusion of the maxillary incisors and a slight skeletal change improved the aesthetic parameters of the facial area.
