Abstract:
This case report presents the treatment of a 12-year-old boy with a complete permanent dentition using self-ligating fixed appliances. The analysis of study models revealed an 8mm space deficiency in the upper and 9mm in the lower dental arch, with a skeletal and dental Class I occlusion. The initial lateral cephalogram showed maxillary normognathism (SNA 82°), mandibular retrognathism (78°), and ANB angle of 4°. There were no vertical skeletal deviations, the SpP/MP angle was 20°. The total Bjork's polygon angle was 389°, the Jarabak's method was 67.7%, the inclination of upper incisors I/SpP was 78°, the inclination of lower incisors i/MP was 95°, with no deviations in the length of the maxilla, mandible and mandibular ramus. Therapy with self-ligating upper and lower fixed appliances was applied, considering the oral inclination of upper and lower incisors, horizontal facial growth pattern and harmonious profile appearance. The fixed appliance therapy lasted for 26 months, with interproximal reduction in the upper and lower anterior teeth region. During the treatment, the dental arches were expanded and adequate space was provided for the proper alignment of all teeth. The retention phase was ensured using retainers worn every night. The therapeutic result was stable, without signs of relapse, with a Class I occlusion on both sides, 2mm overjet and 3mm overbite.

Key words:
severe crowding, self-ligating fixed appliance, interproximal reduction
