Tooth dystopia is a maxillofacial anomaly characterized by an incorrect position of the tooth in the dental arch, or its eruption outside the dental arch. The most common is dystopia of the canines of the upper jaw. According to various scientific data, the development of dystopia is associated with the influence of negative factors on the process of laying and developing the tooth bud. Such factors include: phylogenetic (the size of the jaws decreased during evolution, but the size and number of teeth practically did not change); intrauterine (associated with infections and metabolic disorders); local factors (periodontitis of a temporary tooth, delayed eruption of a temporary tooth, early loss of a temporary tooth, displacement of a dental follicle by a tumor – osteoma, odontoma, cementoma, etc.); deep embedding of the dental follicle in the body of the jaw). Canines play a leading role in the lateral movements of the lower jaw, violation of the biomechanics of the mandible can lead to functional and morphological disorders of the maxillary system. The article presents a clinical case of patient S., 14 years old with tooth dystopia 1.3. Orthodontic diagnostics was performed: impressions, photoprotocol, X-ray with TMJ visualization in natural occlusion, the calculation was carried out using the artificial intelligence program Diagnocat. The patient was treated using an orthodontic microimplant and a self-ligating bracket system. Conclusion. The absolute cortical support provided by orthodontic microimplants greatly facilitates the treatment process, ensuring safe movement of the dystopic tooth. Thereby reducing the duration of treatment and reducing side effects such as tilt of the occlusal plane, intrusion of adjacent teeth and damage to the roots of the lateral incisors.
