Teeth appliance

Abstract

The invention relates to a device for correcting teeth, in particular to a carrier-arch-wire combined tooth correcting device. The tooth correcting device which is disclosed by the invention comprises a buccal tube, a carrier groove, a tooth arch wire and a ligation device; wherein, arch wire grooves in the medial-distal direction are arranged on the carrier groove and the buccal tube; auxiliary channels which have openings in the arch wire groove are arranged in the side walls of the arch wire grooves of the carrier groove and the buccal tube; the auxiliary channels are in the medial-distal direction; one or more than one of the auxiliary channels respectively start from the medial edges and / or the distal edges of the square side walls and / or the gum square side walls of the arch wire grooves; the medial edge and the distal edge of the side wall of the arch wire groove form acute angles with the bottom wall; thus the ligated arch wires can move in the arch wire grooves. The positions of the tooth arch wires in the arch wire grooves and the entering-in and the coming-out of the auxiliary channels can be controlled through adopting different arch wires and cooperating different ligation modes, therefore not only a light force can move obliquely the tooth along the medial-distal direction, but also the tooth is easy to be rooted along the buccolingual direction and the medial-distal direction without additional arch wires. Moreover, the carrier-arch-wire combined tooth correcting device has simple structure and convenient use.

Description

technical field [0001] The invention relates to a device for correcting teeth, in particular to a device for correcting teeth combined with a bracket and an arch wire. Background technique [0002] The United States published the patent No. 4877398 on October 31, 1989, which discloses a dental appliance that can use light force to make the teeth move mesially and distally, without the need for external force anchorage and implant anchorage. To strengthen the anchorage, it can quickly and effectively open the deep overburden of the anterior teeth , but in the later stage, it is more troublesome to use additional arch wires for the mesiodistal and buccolingual root control of the teeth. [0003] The mesial side and the distal side of the side wall of the arch wire slot of the commonly used brackets are at right angles to the bottom wall of the arch wire slot, so that the ligature wire will make the dental arch wire near the bottom wall of the arch wire slot Deformation occu...

[0002] The United States published the patent No. 4877398 on October 31, 1989, which discloses a dental appliance that can use light force to make the teeth move mesially and distally, without the need for external force anchorage and implant anchorage. To strengthen the anchorage, it can quickly and effectively open the deep overburden of the anterior teeth , but in the later stage, it is necessary to use additional arch wires when the teeth are controlled in the mesiodistal and buccolingual directions, which is more troublesome

[0003]The mesial and distal sides of the side walls of the archwire slot of the commonly used brackets are at right angles to the bottom wall of the archwire slot so that the ligature wire Sometimes the arch wire will be deformed at the mesial and distal sides of the bottom wall of the arch wire slot, thereby reducing the degree of freedom of the dental arch wire and increasing the friction force, which is not conducive to the movement of the dental arch wire in the arch wire slot
