Description

Mandibular anterior tooth anchorage device for orthodontics

Technical Field

The invention relates to a mandibular anterior tooth anchorage device for orthodontics, belonging to the technical field of medical appliances.

Background

In the field of the existing orthodontics, because the lower jaw anterior teeth are thinner than roots of other teeth positions and have small periodontal reserve force, the lower jaw anterior teeth have no strong counterforce to directly pull the posterior teeth to move forwards so as to close the tooth extraction gap, and the lower jaw anterior teeth are one of the short plates of the subject;

the traditional mandibular anterior tooth anchorage (commonly called counterforce) is usually characterized in that six anterior teeth of the mandibular are carried out on a bracket provided with a tooth orthodontic device, an 8-shaped ligation method is carried out by using orthodontic ligature wires to serve as mandibular anterior tooth anchorage devices, 0.8mm stainless steel wires are also used for bending auxiliary arches, and the ligature wires are fixed on the mandibular orthodontic device, so that the mandibular anterior tooth anchorage force is further enhanced; in the clinical orthodontics, the two devices can not well achieve the clinical mandibular anterior tooth abutment resistance, and are always pulled backwards by the strong posterior tooth tension-reaction force, which brings a lot of trouble and inconvenience to the clinician.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide the following technical scheme: provides a mandibular anterior tooth anchorage device for tooth orthodontics, which is used for meeting the urgent desire of numerous dentists and patients with dental diseases, improving the success rate of tooth orthodontics and shortening the treatment time.

In order to solve the technical problem, the inventor finally develops a technical scheme of the mandibular anterior tooth anchorage device for tooth orthodontics through long-term research, analysis and experiment in the dental clinical treatment, and the technical scheme is characterized in that: 1. the device comprises a main rod, an auxiliary rod, joints connecting the main rod and the auxiliary rod and traction hooks, wherein the main rod is in a dental arch shape and is made of round stainless steel wires, the left end and the right end of the main rod are respectively provided with one traction hook, a hook handle of each traction hook is respectively connected with one auxiliary rod through the joint, and each auxiliary rod is respectively provided with 2-3 auxiliary tube supporting grooves;

2. the main rod is prefabricated by a round stainless steel wire with the diameter of 1.2mm, and the arc of the main rod is consistent with the arc of the dental arch of the front section of the lower jaw anterior teeth and the middle section of the lower jaw dentition in the oral cavity of a human body to form an arch filament;

3. the two traction hooks are respectively perpendicular to the main rod, the length of the two traction hooks is 5-10mm, the diameter of each hook is 1-2mm, openings of the two traction hooks face the middle point of the main rod, and the traction hooks and the needle rod are integrated;

4. the joint is of a hinge structure, one end of the joint is connected to a hook handle of the traction hook at the tail end of the main rod, the other end of the joint is fixed at one end of the auxiliary rod, and the auxiliary rod can rotate through the joint; an accessory tube bracket is fixed on one surface of the joint;

5. the auxiliary tube bracket is two movable tubular auxiliary bodies, is attached to the auxiliary rod through a movable tube, and can be freely adjusted in position.

Compared with the prior art, the invention has the following substantive characteristics and remarkable progress:

1. because two movable tubular auxiliary canal brackets are respectively designed on both sides of the device, the device can be firmly and stably fixed on a dental bed, is favorable for clinical installation and operation, the 1.2mm circular arch-shaped main rod of the device can tightly connect the lower jaw front tooth section and the middle tooth section together to form strong one-section type resistance combined force,

2. the traction hook of the device is ingenious in structural design, the traction hook is close to the resistance center of the lower jaw tooth root after installation, the function of stabilizing acting force and reacting force can be achieved, the side effect caused by insufficient resistance of the lower jaw anterior tooth can be solved, and therefore the traction hook can be effectively applied to the clinical technology of orthodontics, the correction time is shortened, the success rate of orthodontics is improved, good news is brought to patients, and a new practical tool is added to orthodontics of the lower jaw anterior tooth;

3. the device is skillfully installed, strong in fixation and good in resistance, can be installed for the first time, and is not influenced by the tidiness, crowding or crowding degree of the dentition, the orthodontic bracket adhesive is used for bonding and fixing the orthodontic bracket adhesive, the bonding positions are respectively the lower jaw canine tooth neck, the lower jaw first premolar tooth neck and the lower jaw second premolar tooth neck, and the orthodontic bracket adhesive is firmly fixed into a whole, so that the lower jaw anterior tooth anchorage is enhanced by the characteristic that the tooth neck is closer to the tooth moving resistance center, and the traditional anchorage is far away from the tooth moving resistance center, so that the problem that the tooth crown and the tongue of the lower jaw incisor are seriously inclined can be easily caused;

4. the device has the advantages of convenience, clinical selection of finished products of the device, more convenience, avoidance of complication of operation beside a doctor chair and saving of operation time beside the chair;

5. the cost is low, and compared with the traditional standard mandibular anterior tooth bracket or the combination of the bracket and the auxiliary arch, the cost is much lower;

6. the flexible selection has the advantages that a clinician can select the first installation and use, a large number of gaps are closed after the lower jaw molar extraction is completed, the lower jaw intramaxillofacial traction can be completed for the first time by matching with a posterior segment arch technology, and the lower jaw intramaxillofacial traction can also be completed with the jaw traction in different forms of the upper jaw, so that the lower jaw front tooth strengthening anchorage device integrating the lower jaw into a whole can be used for completing the lower jaw front tooth strengthening anchorage device.
