摘要：
The utility model relates to medicine, in particular to dentistry, and can be used as a tool for skeletal support during orthodontic treatment of patients with skeletal and dentoalveolar abnormalities using the maxillofacial region, an orthodontic minivint for skeletal support during orthodontic treatment of patients with skeletal and dentoalveolar anomalies using in the maxillofacial region, consisting of the main part of a cylindrical shape with an external screw thread, a shake and a hexagonal head, characterized in that bioinert and high-strength titanium is used as the material, and the intraosseous part has a thread pitch of 1 ± 0.02 mm and a thread angle of 60 ° for the convenience of screwing it into bone tissue and increasing stability after its installation, and half-sliced apex to increase the sharpness and eliminate blunting of the apex when interacting with bone tissue of various densities, while the length of the threaded portion varies from 5 ± 0.5 mm to 11 ± 0.5 mm for use in various parts of the maxillofacial about areas, and the transgingival part of the minivint has a smooth cone-shaped transition to the neck, which prevents trauma and inflammation of the gums during the period of orthodontic treatment, while on the neck of the orthodontic minivint there is a round or rectangular hole for introducing an orthodontic ligature or spring for moving teeth within the dentoalveolar arch, and the part of the neck of the mini-screw turning into the head is made smooth for fastening the orthodontic power traction and other orthodontic structures. The advantages of the proposed method include: the model material is bioinert and safe for the human body； the shape of the transgingival part of the minivint reduces the risk of inflammation and gum injury； half-cutting of the minivint apex increases its sharpness and facilitates easier installation of the minivint when interacting with bone tissue of different densities； the angle of the thread is 6 0 ° for the c
