Technical Field

The invention relates to the field of orthodontic treatment, in particular to a positioning unit, a positioner and a positioning method of an orthodontic bracket.

Background

In current orthodontic treatment, direct bonding is generally used when bonding brackets to tooth surfaces. Since the prior art direct bonding technique is manual bonding based on the experience of the doctor, this method is highly dependent on the skill of the doctor in bonding and visual observation. The working intensity is high, the efficiency is not high, the repeatability is not good, and the accuracy is not ideal. Nevertheless, due to its intuitive nature, it is still widely used in clinical practice by most orthodontists.

To overcome these disadvantages of the direct bonding technique, an indirect bonding technique has been developed. Indirect bonding techniques involve the bonding of orthodontic brackets to a working model and the transfer of the bonded brackets from the model to the tooth surface by some transfer device.

However, the existing indirect bonding technology cannot match with the arch wire at the same time during bonding, and only can arrange the arch wire separately after bonding. Therefore, the doctor operating time is increased; and it is difficult to restore the position of the designed original arch wire, resulting in a reduction in the efficiency of correction.

Moreover, when operating in the mouth, a doctor is easy to install a reverse arch wire due to insufficient light in the mouth space or forget to handle the tail end of the arch wire, so that a patient is stabbed by the arch wire.

Detailed Description

Unless otherwise indicated, in the following structural description, the reference frame to the mandibular teeth is used to describe the inclination identifier locator. Thus, as used herein, terms such as labial, lingual, mesial, distal, occlusal, gingival used to describe the positioner are relative to a selected frame of reference. However, embodiments of the present invention are not limited to the chosen frame of reference and the terms described, as the positioner may be used for other teeth and other orientations within the oral cavity. For example, the positioner may also be coupled to the lingual surface of the teeth and fall within the scope of the invention. Those skilled in the art will appreciate that when there are variations in the reference frame, the descriptive terms used herein may not be directly applicable. However, embodiments of the invention are intended to be independent of position and orientation within the oral cavity and the relative terms used to describe the embodiments are merely intended to provide an unambiguous explanation of the embodiments in the drawings. Likewise, the relative terms labial, lingual, mesial, distal, occlusal and gingival are in no way intended to limit the present invention to a particular position or orientation.

It should be noted that the relative terms labial, lingual, mesial, distal, occlusal and gingival are terms of art for orthodontic treatment. Taking a certain tooth of the lower jaw as an example, the surface of the tooth can be roughly divided into six surfaces. The surface of the tooth that bites the upper jaw tooth is the occlusal surface; the surface of the tooth that is in contact with the gingival tissue to which it is attached is the gingival surface; the occlusal surface is opposite to the gingival surface, and the direction formed by the occlusal surface and the gingival surface is also called the gingival engaging direction. The tooth surface facing the lips is the labial surface, the tooth surface facing the tongue is the lingual surface, the labial surface is opposite to the lingual surface, and the direction formed by the labial surface and the lingual surface is also called the labial-lingual direction. The two surfaces of the tooth that contact the adjacent teeth are the mesial and distal surfaces, respectively, and the difference is the distance from the middle, and the direction formed by the two is also called the mesial-distal direction, or the mesial-distal direction.

And in the description of the direction, such as the labial and lingual directions, it is commonly referred to as bi-directional. However, the distinction is made that the term "lip-tongue direction" refers to a single direction, i.e., a direction from the labial side to the lingual side.

The shaft inclination mark positioning mark is also called as a shaft inclination mark, and means that an inclined line which is arranged on the orthodontic bracket and has the same shaft inclination angle as the orthodontic bracket, namely the shaft inclination line, is used for more accurate positioning when a doctor uses the bracket to be bonded to a tooth surface.
