Abstract

The utility model relates to the field of orthodontics, and aims to provide an orthodontic bracket with band-shaped arch wires. The orthodontic bracket comprises a bracket main body, a groove and a net bottom, wherein the section shape of the bracket groove is a horizontal rectangle with the width of 0.028 inches and with the height of 0.025 inches. The orthodontic bracket has the benefits the transverse size of mounted tooth arch wires is increased, so that the rectification force of the tooth arch wires can be more soft; flaring openings in the two ends of the groove can reduce restraining force of the two ends of the groove to the arch wires, and as a round wire is used at the early stage, the inclined movement angle of teeth can be increased; due to the flaring openings, the slide contact distance between the groove and the arch wires is shortened, and the sliding friction force is reduced; as original tooth arch wires are still used, so that the operation habit of a doctor cannot be changed, and the use is convenient.

Description

Banded bow correction bracket

Technical field

This utility model relates to mouth cavity orthodontic field, is specifically related to banded bow correction bracket.

Background technology

At present, fixed orthodontic technology is mainly that the power producing by dental arch filament applies corrective force through the transmission of bracket to malposed tooth to the rectification of malocclusion, and tooth is moved, and malposed tooth is corrected.In existing clinical rectification, dental arch filament (side's silk) conventionally all can be vertically longitudinally to enter groove mode, therefore can produce larger corrective force and frictional force, although the larger power of rescuing can allow tooth fast moving, in clinical Tooth Movement process, patient can produce obvious dental pain and discomfort.Therefore, light power is rescued, low-frictional force is rescued is research highly significant.

The size of light power, frictional force is relevant with several factors, wherein one of very important reason of design of bracket groove.Normally right angle and be vertical longitudinal design, existing bracket groove two ends in the market, this design not only makes the distance that contacts of arch wire and bracket, cause frictional force large, and the strength that dental arch filament discharges is also very large, therefore this design allows bracket produce very large restraining forces to arch wire, if wish tooth fast moving, need larger strength to overcome these constraints, and more painful these strength tend to bring to patient.

Utility model content

The technical problems to be solved in the utility model is, overcomes deficiency of the prior art, and a kind of banded bow correction bracket is provided.

In order to solve the problems of the technologies described above, this utility model adopts following solution:

A kind of banded bow correction bracket is provided, comprises bracket main body, groove and net bottom; The cross sectional shape of described bracket groove is horizontal direction rectangle, and its width is 0.028 inch, is highly 0.025 inch (side's silk adopts transverse horizontal to enter groove mode while entering groove).

Improve as one, the two ends of described groove are also provided with the bell mouth shape enlarging that outer imperial palace is little, the angle number of degrees≤45 of flared edge and groove edge formation ° (this structure can be as straight arch wire appliance can prefabricated three sequence bendings data).

Compared with prior art, the beneficial effects of the utility model are:

1, the design of improved groove cross sectional shape, its essence is the upset of conventional bracket groove (archwire slot) having been carried out to 90 °; That is, former width is become to height, former height is become to width.Like this, square dental arch filament by original vertically insert to change into laterally insert.Because the lateral dimension of the dental arch filament after installing increases, make the corrective force of dental arch filament become softer.

2, the enlarging at groove two ends can reduce the restraining forces of groove two ends to arch wire, and uses circle silk can also increase the inclination move angle of tooth in early stage, and design of the present utility model promotes the movement of tooth on arch wire to a great extent.

3, due to the existence of enlarging, shorten the sliding-contact distance of groove and arch wire, reduce force of sliding friction;

4, owing to still using former dental arch filament, can not change doctor's operating habit, easy to use.

The specific embodiment

Further illustrate content of the present utility model below in conjunction with accompanying drawing, want protection domain to only limit to this but should not be construed as this utility model.

Banded bow correction comprises bracket main body 1, traverses the groove 2 in the middle of bracket main body and is connected to the net bottom 6 of bracket main body 1 bottom with bracket; The cross sectional shape of groove 2 is horizontal rectangle, and its width equates with the groove height of conventional bracket, and its height equates with the groove width of conventional bracket, and side thread adopts transverse horizontal to enter groove mode while entering groove.That is: the width in the rectangle cross section of groove 2 is 0.028 inch, is highly 0.025 inch.Be provided with the bell mouth shape enlarging that outer imperial palace is little at the two ends of groove 2, the angle α number of degrees≤45 ° that flared edge and groove edge form.

In use, the net bottom of bracket 6 is bonded on patient's tooth, in previous tretament process, selects the correction circular silk 7 of diameter≤0.20 inch to put into groove 2, then orthodontic bow-wire 7 is carried out to untwisting bundle with ligature 5.Now, between orthodontic bow-wire 7 and groove 2, have a gap angle β (β >5 °).And the enlarging 3 at groove 2 two ends can reduce the frictional force that the right angle at the groove two ends of conventional bracket brings to orthodontic bow-wire 4/7 to a great extent.

Claims

1. banded bow correction bracket, comprises bracket main body, groove and net bottom; It is characterized in that, the cross sectional shape of described bracket groove is horizontal direction rectangle, and its width is 0.028 inch, is highly 0.025 inch.
