Description

Braces

This creation relates to a braces for correcting teeth, and in particular to a braces that are occluded by teeth to correct malocclusion.

In addition to affecting the chewing function or the pronunciation function, the teeth may cause oral health problems such as tooth decay, periodontal disease or abnormal tooth wear. Nowadays, more and more people are making teeth for the beauty and health of teeth. Correction.

At present, the common way to correct the teeth is to fix the orthosis on each tooth surface, and then install the correction line on each orthotic device. Next, pull the correction line to change the arrangement position of the teeth, thereby changing the overall appearance of the teeth and the malocclusion. However, at present, both the aligner and the correction line are adhered to the outside of the tooth, so that both the aligner and the correction line are located on the buccal side of the patient's teeth, thereby not only affecting the patient's teeth, but also the aligner and the correction line. Scratching the inside of the cheeks caused a broken skin.

In order to avoid the use of orthotics and correction lines to correct the missing teeth, some patients will use a beautiful transparent braces to correct the teeth, wherein when the transparent braces are mounted on the dental arch, the transparent braces will be on the side of the arch The surface exerts a horizontal force to adjust the tooth to the desired position. However, if the current transparent braces are not equipped with additional components (such as springs, correction lines), it is difficult for the transparent braces to exert longitudinal force on the dental arch to correct the teeth. Transparent braces are difficult to correct for malocclusion.

The main purpose of this creation is that when the upper and lower dental arches are engaged, the braces will form a correction force that is nearly perpendicular to the occlusal surface, so that the more prominent teeth in the dental arch are corrected by the correcting force to improve the occlusion between the upper and lower dental arches. The problem.

The secondary purpose of this creation is that in addition to the corrective force that is nearly perpendicular to the occlusal surface, the braces can also produce an elastic force that is nearly parallel to the occlusal surface, so that the corrective arch can be corrected by both corrective and elastic forces. In order to shorten the correction time to improve efficiency.

In order to achieve the foregoing object, the present invention relates to a dental mouthpiece which can be assembled on a corrective dental arch and used with a pair of dental arches on one side of the above-mentioned corrective arch. The corrective dental arch has a plurality of different height positions. The occlusal surface is formed by a plurality of elastic arms, at least one extension block, and at least one correction block.

The plurality of elastic arms are in contact with the inner side or the outer side of the correcting arch, and do not exceed the occlusal surface of the lowest height position, and one end of the extending block is formed on the elastic arm, and the height of the other end is the same as the highest height position. The occlusal surface, the aligning block is in contact with the occlusal surface at the highest height position, and is formed on the extending block, and the correcting block forms a correcting plane on a side away from the occlusal surface to engage the occlusal arch A portion of the above-described orthodontic arch is corrected by a corrective force that is substantially perpendicular to the occlusal surface.

Wherein the dental mouthpiece has a contour that is larger or smaller than the corrective contour of the corrective dental arch, and when the dental mouthpiece is mounted on the corrective dental arch, the plurality of elastic arms are deformed by being squeezed or expanded by the corrective dental arch, so that The elastic arm produces an elastic force that is nearly parallel to the occlusal surface to correct the corrective arch.

In a preferred embodiment, the plurality of elastic arms are connected to each other to form a bow-shaped elastic arm, and the inner or outer side of the bow-shaped elastic arm forms the correcting contour, and the elastic arm is located at two or two of the elastic arms. The joint is deformed as a fulcrum to form the elastic force, and the opposite ends of the bow-shaped elastic arm respectively have the above-mentioned extension block and the correction block.

In another preferred embodiment, the plurality of elastic arms are connected to each other to further form an auxiliary bow type elastic arm connected to the bow type elastic arm, and the bow type elastic arm and the auxiliary bow type elastic arm surround the correcting tooth. a bow such that one of the arched arm and the auxiliary arched arm is located inside the corrective arch, and the other of the arched and auxiliary arched arms is located in the corrective arch The outside.

Wherein, the bow-shaped elastic arm and the auxiliary arch-type elastic arm together form an opening for allowing the correcting dental arch to be convex, and the extending block is located above the arch-shaped elastic arm and the auxiliary arch-shaped elastic arm, so that the above The opening is provided with a covering portion covered by the above-mentioned correcting block and an exposed portion not covered by the correcting block.

In a further preferred embodiment, the opposite ends of the correcting block respectively form the extending block and the elastic arm, and the elastic arm, the extending block and the correcting block jointly form the correcting contour, and the elastic arm is as described above. The extension block is deformed as a fulcrum to form the elastic force, wherein the extension block is provided with a plurality of interconnected elastic arms at an end away from the correction block, so that the plurality of elastic arms collectively surround a part of the correction arch.

In the foregoing three embodiments, one of the plurality of elastic arms, the extension block and the correction block is provided with a connecting portion, and the connecting portion is connected with an elastic member, so that the elastic member can apply a force to the elastic arm. The direction is different from the external force of the above-mentioned correcting force.

The feature of this creation is that when the dental mouthpiece is assembled in the corrective dental arch, the elastic arm does not exceed the occlusal surface of the lowest height position in the corrective arch, and the correcting block contacts the occlusal surface at the highest height position in the corrective arch, thereby correcting the dental arch. When the bite arches are engaged with each other, a part of the teeth of the correcting arch and the biting arch will bite into the correcting block, and the remaining teeth of the orthodontic arch and the biting arch do not touch each other to engage, so that the correction The block will produce a nearly vertical correction force on some of the teeth in the corrective arch, and then some of the teeth of the corrective arch are corrected by correcting force to improve the problem of misalignment between the orthodontic arch and the bite.
