Technical Field
The utility model relates to the technical field of dental treatment, more specifically say, relate to an orthodontic arch wire.
Background
With the application of digital technology in the oral cavity industry, more and more people choose to use individualized lingual products, namely individualized lingual brackets and individualized lingual archwires. However, the individualized lingual correction is different from labial correction, and generally, the front teeth of the individualized lingual bracket are vertical grooves, and the rear teeth are horizontal grooves, so that the stress difference of the front and rear areas of the teeth is large, the control requirements of the front teeth area on torque and axial inclination are high, and the requirements of the rear teeth area on the sliding performance and stability of the teeth are high, so that the function of taking both the front teeth and the rear teeth into consideration is difficult to realize by using the conventional arch wire with the same size.
SUMMERY OF THE UTILITY MODEL
For overcoming the defects of the prior art, the utility model provides an orthodontic arch wire, which takes into account the control requirements of the front tooth area on the torque and the shaft inclination and the requirements of the back tooth area on the sliding property and the stability.
The utility model provides a technical scheme that its technical problem adopted is:
the orthodontic arch wire comprises an arch wire body with an arc structure, wherein the sections of an anterior tooth section in the middle of the arch wire body and posterior tooth sections on two sides of the arch wire body are both rectangular, the height dimension of the section of the anterior tooth section is larger than the width dimension, and the width dimension of the section of the posterior tooth section is larger than the height dimension.
Preferably, the clearance between the sides of the front tooth section and the trough is less than 0.002 inch.
Preferably, the gap between the upper surface of the posterior tooth section and the trough is greater than 0.001 inches.
Preferably, the height dimension of the cross-section of the front dental segment is greater than the height dimension of the cross-section of the rear dental segment.
Preferably, the width dimension of the cross-section of the anterior dental section is smaller than the width dimension of the cross-section of the posterior dental section.
Preferably, the archwire body is integrally formed.
Preferably, the edges of the front tooth section and the back tooth section are both in circular arc transition.
Preferably, the material of the arch wire main body is stainless steel.
The utility model has the advantages that: through setting the arch wire main part to anterior teeth district section and back tooth district section, and set the height dimension of cross-section to anterior teeth district section to be greater than the width dimension, the width dimension in the cross-section of back tooth district section is greater than the height dimension for the arch wire has better torque and axle slope to the anterior teeth district of tooth, has better gliding nature and stability to the back tooth district of tooth. The utility model discloses simple structure, excellent in use effect easily uses widely.

Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the orthodontic archwire of this embodiment includes an archwire body 1 having an arc structure, wherein cross sections of an anterior tooth segment 11 in a middle of the archwire body 1 and posterior tooth segments 12 on both sides of the archwire body are both rectangular, a height dimension of the cross section of the anterior tooth segment 11 is greater than a width dimension, and a width dimension of the cross section of the posterior tooth segment 12 is greater than a height dimension.
Based on the orthodontic arch wire of the technical characteristics, the arch wire body 1 is set into the front tooth section 11 and the rear tooth section 12, the height dimension of the cross section of the front tooth section 11 is larger than the width dimension, and the width dimension of the cross section of the rear tooth section 12 is larger than the height dimension, so that the arch wire has better torque and shaft inclination to the front tooth area of the teeth and better sliding property and stability to the rear tooth area of the teeth. The utility model discloses simple structure, excellent in use effect easily uses widely.
In addition, the width dimension of the back tooth section 12 is larger than the height dimension, so that the horizontal side face of the back tooth section 12 of the arch wire can be thickened, the front tooth section 11 can smoothly enter the groove 2, meanwhile, the bending stress can be improved, the control force of the arch wire to the horizontal direction of the back tooth section teeth is increased, and the back tooth section teeth can reach target positions more quickly.
In this embodiment, to facilitate torque control in the front teeth area, the clearance between the side of the front teeth section 11 and the slot 2 is less than 0.002 inch. In addition, the height dimension of the cross section of the anterior dental section 11 is greater than the height dimension of the cross section of the posterior dental section 12.
In this embodiment, the gap between the upper surface of the rear tooth section 12 and the slot 2 is greater than 0.001 inch. The arrangement can greatly help to reduce the sliding resistance of the arch wire on the rear tooth bracket groove, the rear tooth section 12 is easy to enter the groove 2 when the arch wire is installed, the smooth sliding of the arch wire is helped, and the time period of the closing gap stage in the tongue side orthodontic correction process is greatly reduced. In addition, to increase the stability of the posterior dental section, the anterior dental section has a cross-sectional width dimension that is less than the cross-sectional width dimension of the posterior dental section.
In this embodiment, in order to increase the strength of the arch wire, the arch wire body 1 is integrally formed, and the arch wire body 1 is made of stainless steel. In addition, in order to prevent the arch wire from scratching the oral cavity, the edges of the front tooth section 11 and the back tooth section 12 are in arc transition.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
