Description

Invisible correcting structure for low post-molar

Technical Field

The utility model relates to the field of tooth orthodontics, in particular to a method for invisible correction of molar after depression.

Background

Anterior mandibular opening refers to the fact that when a patient is engaged, the anterior maxillary teeth are not in contact with the anterior mandibular teeth in the vertical direction. There are many hazards of anterior mandibular opening, such as inability of the anterior teeth to cut food, affecting patient breathing, swallowing, etc. The front teeth are opened for a plurality of reasons, and the main expression form is that one or more rear teeth in the oral cavity are prolonged too much, and when the rear teeth bite, a fulcrum is formed, so that the incisors cannot be folded.

In the treatment of open jaw patients, it is often necessary to depress the posterior teeth. Posterior tooth depression is a difficult type of movement in orthodontic applications and often requires the use of an anchorage pin to assist in moving the teeth. The use of the anchorage bone nails is costly and is uncomfortable for the patient. In recent years, the technology of the invisible bracket is continuously developed, and the functional invisible bracket appliance is popular with more doctors and patients due to the advantages of convenient manufacturing, invisible and beautiful appearance, convenient taking and wearing, and the like. However, the effectiveness of the invisible appliance is not ideal in depressing the post-molar (last tooth of the dentition).

1. The tooth grinding device comprises a tooth grinding accessory with a low back pressure, a boss, a semicircular boss, an arc concave edge, a hanging part, a tooth grinding sleeve with a low back pressure, a tooth grinding part 7, a tooth grinding part 8, a fixing accessory, a tooth grinding part 9 and an orthodontic rubber chain.

Detailed Description

Specific embodiments of the present utility model will be further described with reference to the accompanying drawings.

As shown in the figure, the invisible correcting structure for the low back molar comprises a low back molar sleeve 7 and a low back molar accessory 1, wherein the low back molar accessory 1 is arranged on the outer side surface of the inner side area of the back molar position 7 of the low back molar sleeve 6, and the inner side surface of the angle is not shown in the figure. The low post-molar attachment 1 is T-shaped, and the low post-molar attachment 1 is used for hooking an orthodontic rubber chain 9. The depressed post-molar shell 7 and the depressed post-molar shell 7 form two empty slots as shown in fig. 3 for passing through the orthodontic rubber chain 9.

One end of the orthodontic rubber chain 9 is hooked on the inner side of the low back molar attachment 1, and the other end of the orthodontic rubber chain is transversely hooked on the outer side of the low back molar attachment 1 from below. After wearing, the orthodontic rubber chain 9 is pressed over the teeth.

The low post-molar attachment 1 and the low post-molar shell 7 are integrated, so that the stress effect is good, and the traditional adhesive type falling risk is avoided.

The low back molar attachment 1 comprises a hanging part 5 and a semicircular bulge 3, wherein the semicircular bulge is arranged below the hanging part 5.

Arc concave edges 4 are arranged above two sides of the hanging part 5, and the arc structures on the two sides provide position indication for the cutting hanging part 5.

The bottom edge of the low back molar attachment 1 is provided with the boss 2, so that the orthodontic rubber chain 9 is not easy to fall off.

The tooth socket 6 is provided with a fixed accessory 8, and the fixed accessory 8 is arranged on the tooth socket 6 at the front side of the low back molar accessory 1.

The orthodontic rubber chain 9 is slightly tensioned when hung, and the discomfort during correction can be relieved in view of the softer material.

When the patient wears the appliance into the oral cavity, the tension force of the rubber chain and the upper and lower jaw biting force jointly act on the posterior molar, so that the posterior molar is low, and the anterior tooth jaw opening symptom is improved.

When the invisible correcting structure for the low back molar is used, a digital tooth model of a patient is firstly rebuilt, then the low back molar accessory 1 is placed on the labial and lingual sides of the back molar of the digital tooth model, the low back molar accessory 1 exists in pairs, and the retention accessory is placed on the labial side or lingual side of the adjacent teeth. Then, the low-back molar accessory 1 is guided out along with the digital model and printed into a 3D dental model, the diaphragm is pressed on the dental model through a thermoplastic molding process, a series of processes such as cutting, polishing, sterilizing and the like are performed, the invisible appliance with the hanging part 5 is manufactured, and finally, the orthodontic rubber chain 9 is hung on the invisible appliance, so that the manufacturing is completed. The position of the blister attachment is personalized to the patient's teeth.
