Lower jaw anterior tooth anchorage device for tooth orthodontia

Abstract

The invention relates to a lower jaw anterior tooth anchorage device for tooth orthodontia. The lower jaw anterior tooth anchorage device for tooth orthodontia consists of a main rod, auxiliary rods,joints for connecting the main rod with the auxiliary rods and traction hooks, wherein the main rod is in the shape of a dental arch, and is manufactured from circular stainless steel wires; the traction hooks are arranged at the left end and the right end of the main rod; each auxiliary rod is connected to the hook handle of the corresponding traction hook through the corresponding joint; and 2-3pipe adhering supporting grooves are formed in each auxiliary rod. The lower jaw anterior tooth anchorage device for tooth orthodontia disclosed by the invention can be firmly and stably fixed to gum, so that clinical mounting and operating are facilitated; the circular dental arch-shaped wire body of which the diameter is 1.2mm is arranged, so that the teeth in an anterior tooth section and teeth in a mesiodens section can be tightly connected and combined together to form a strong one-section type resistance combined force; after the lower jaw anterior tooth anchorage device is mounted, thetraction hooks are close to the resistance center of the tooth root of the lower jaw, so that the effects of stabling action force and reaction force can be achieved, and the problem that negative effects are caused by insufficient resistance of the anterior tooth at the lower jaw can be solved; and the lower jaw anterior tooth anchorage device can be effectively applied to an orthodontic treatment clinical technique, so that the orthodontic treatment time is reduced, the success rate of the orthodontic treatment and tooth orthodontia is increased, and good news is brought to a patient.

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 subject; [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 f...

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
