A mandibular anterior teeth anchorage device for orthodontics

Abstract

An anchorage device for mandibular anterior teeth for orthodontics, the device is composed of a main rod, an auxiliary rod, a joint connecting the main rod and the auxiliary rod, and a traction hook, wherein the main rod is in the shape of a dental arch, with a circular Made of stainless steel wire, a traction hook is designed at the left and right ends of the main pole, and the hook handle of each traction hook is respectively connected with a sub-rod through a joint, and each sub-rod is designed with 2-3 attached pipes Brackets. The invention can be firmly and stably fixed on the gum bed, which is beneficial to clinical installation and operation. Its 1.2mm circular dental arch-like filament can tightly connect the mandibular anterior segment and the middle segment of the tooth as a whole to form a strong segment. Combination force of type resistance. After installing the device, the traction hook is close to the resistance center of the mandibular tooth root, which can play the role of stabilizing force and reaction force, and can solve the negative effect caused by the lack of resistance of the mandibular anterior teeth, and can be effectively applied to the teeth. In orthodontic clinical technology, shorten the treatment time, improve the success rate of orthodontic correction, and bring good news to patients.

Description

technical field [0001] The invention relates to a mandibular anterior tooth anchorage device for orthodontics, belonging to the technical field of medical instruments. Background technique [0002] In the current field of orthodontics, because the roots of the mandibular anterior teeth are thinner than those of other teeth and the periodontal reserve force is small, the mandibular anterior teeth have always had no strong resistance to directly pull the posterior teeth forward to close the extraction The gap has always been one of the shortcomings of this discipline; [0003] The traditional mandibular anterior teeth anchorage (commonly known as resistance) often shows that the six anterior teeth of the mandible are carried out on the brackets equipped with orthodontic appliances, and the "8" ligation method is performed with orthodontic ligature wire as the mandibular anterior teeth. 0.8mm stainless steel wire is also used to bend the auxiliary arch, and the ligature wire i...

Problems solved by technology

[0003] The traditional mandibular anterior teeth anchorage (commonly known as resistance) often shows that the six anterior teeth of the mandible are carried out on the brackets equipped with orthodontic appliances, and the "8" ligation method is performed with orthodontic ligature wire as the mandibular anterior teeth. 0.8mm stainless steel wire is also used to bend the auxiliary arch, and the ligature wire is fixed on the mandibular appliance to further enhance the anchorage of the mandibular anterior teeth; these two devices cannot achieve clinical mandibular alignment well in clinical orthodontics. The anchorage of the anterior teeth is always pulled backward by the strong pulling force of the posterior teeth—the reaction force, which brings a lot of trouble and inconvenience to the clinicians. Because of the large difference in the periodontal reserve force of the anterior and posterior teeth during orthodontic treatment, How to use the weak mandibular anterior teeth combined anchorage device to complete the clinical traction of the mandibular posterior teeth to move forward is very urgent
