Abstract
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.
