Description
Technical Field
The utility model relates to a tooth just abnormal apparatus technical field, concretely relates to support just abnormal planting anchorage nail of cylindrical.
Background
Orthodontic treatment is mainly to adjust the coordination among nerves and muscles of facial bones, teeth and maxillofacial parts, that is, to adjust abnormal relationships among maxilla and mandible, between upper and lower teeth, between teeth and jawbone, and between nerves and muscles connecting them, by various orthodontic devices, with the ultimate aim of correction being to achieve balance, stability and beauty of the oromandibular system. In the orthodontic correction process, any force applied to a tooth to be treated to move the tooth necessarily generates a force with opposite direction and same magnitude at the same time, and the condition of supporting the reaction force caused by the movement of the tooth body is called as anchorage, wherein the anchorage is a basis for providing the tooth correction force, and the high-quality correction result can be obtained only by correct anchorage design and good anchorage control.
In conventional orthodontic treatment, orthodontists often spend a great deal of time and effort controlling anchorage to move as many teeth as desired and as few teeth as desired. In order to simplify the mechanical mechanism of orthodontic treatment and obtain better treatment effect, the implantation anchorage is generated by itself. In the implant anchorage technology, the orthodontic implant anchorage nail is greatly developed in the implant anchorage technology because of its small size and relatively simple and convenient implantation, use and removal, wherein the miniature titanium nail implant anchorage nail can be conveniently implanted into any required part of jaw bone as a temporary anchorage device, and is widely applied clinically.
In order to ensure sufficient strength of the micro titanium nail, the nail body of the common micro titanium nail has a diameter of 1.2-2.0mm and a length of 4.0-21 mm. However, such micro titanium spikes with a diameter of 1.2-2.0mm limit the planting gap.
