Relevance. Skeletal Class III malocclusion is known to be one of the most difficult malocclusions to correct. Nonsurgical treatment of Class III in adults is a challenge; however, this patient refused surgery. A treatment method with Fixed Anterior Growth Guidance Appliance (FAGGA) was investigated in the study.Materials and methods. This case report presents a 37-year-old woman with skeletal Class III malocclusion for maxillary deficiency. As the patient didn’t agree to surgery, she was treated by Fixed Anterior Growth Guidance Appliance, followed by 3D SMILE® clear aligners. Fixed Anterior Growth Guidance Appliance was used initially. After 4 months, the appliance was removed and clear aligner treatment was initiated. Post-treatment radiographs showed improvement.Results. Intraorally, in the upper arch, a total of 4.00 mm of space were gained (about 2.00mm distal to each canine). The post-treatment cephalometric analysis showed a skeletal A-P Class I, the Upper incisor inclination to the optic plane was not significantly altered, ANS — antArc was improved by 1.5mm, the Effective Length of the Premaxilla increased by 2.6mm, U1 — ANS’ decreased by 1.7mm, Incisor mandibular plane angle (IMPA) autonomously improved by 11 degrees.Conclusions. Maxillary deficiency was corrected successfully with the Fixed Anterior Growth Guidance Appliance. The treatment is being continued by 3D SMILE® clear aligners. The goal was achieved despite the patient’s age and nonsurgical treatment.

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.

A 20-year-old man presented at our clinic with a primary complaint of irregular dentition and reverse bite. Clinical examination revealed skeletal Class III malocclusion with an anterior crossbite and a completely blocked #25 in the maxilla. Because he refused to receive orthognathic surgery and experienced only mild functional interference, a nonextraction treatment method was adopted. Space creation on the left upper arch was successfully performed using an open coil spring for molar distalization and the improved super-elastic Ti–Ni alloy wire (ISW) Multi-bends Edgewise Arch Wire (MEAW) technique. Furthermore, #25 was aligned completely. The Class III malocclusion was corrected using the ISW MEAW technique combined with Class III elastics on the lower arch. Treatment was completed in approximately 16 months and a satisfactory occlusion was achieved after active treatment.

ABSTRACT Treatment of hyperdivergent skeletal Class III malocclusion is challenging for orthodontists, and orthognathic-orthodontic treatment is usually required. This report presents the successful nonsurgical treatment of a 20-year-old man who had a skeletal Class III malocclusion with anterior open bite, anterior and posterior crossbite, hyperdivergent growth pattern, steep occlusal plane, early loss of three first molars, and an uncommon convex profile with a retruded chin. An orthodontic camouflage treatment plan was chosen based on the etiology and the patient's complaints. Tooth #37 was extracted. Miniscrews were used for uprighting and intruding of the lower molars, distalization of the lower dentition, and flattening of the occlusal plane. After 34 months of active treatment, Class I relationships, proper anterior overjet and overbite, flat occlusal plane, and an esthetic facial profile were achieved. The results demonstrated that the biomechanics involved in the nonsurgical treatment assisted with miniscrews to distalize the mandibular dentition and flatten the occlusal plane while keeping the mandibular plane stable was effective for treating this hyperdivergent skeletal Class III patient with a convex profile and anterior open bite.
