Abstract

The utility model relates to a trumpet mouth bracket comprising a base and a bracket seat fixed on the base and provided with a trough gutter. The lateral of the bracket base is opened with a bonding groove, which is characterized in that the opening of the groove is opened with a trumpet-shaped flaring for the formation of a trough gutter structure which is gradually smaller from the opening of the trough gutter to the trough bottom. Because the inlet width of the trumpet mouth-shaped trough gutter is larger, clinically, the arch wire can smoothly enter the inside of the trough gutter of bracket on each facing. When the transposition of teeth is serious, the arch wire can firstly enter the opening of the trumpet moouth-shaped trough gutter, which is gradually slide into the trough gutter along the trumpet mouth shaped slope with the improvement of the transposition of teeth. The utility model has a rational design with easy operation. Not only the inconvenience of frequent clinical replacement of arch wires and the treatment time are reduced, but also the corrective force and the tooth movement are relatively stable. Therefore, the tooth pain is reduced.

Description

The horn mouth bracket

Technical field:

This utility model belongs to the medical apparatus field, and particularly a kind of straightening of teeth has a bell-mouthed bracket.

Background technology:

Tradition side's silk bow one straight silk bow supporting groove structure is by a diapire that matches with tooth surface and is fixed on the bracket seat that offers the flat recess ditch on the diapire, offers ligature furrow outside the bracket seat.During clinical capable orthodontics,,, rely on the strain resilience force of arch wire to rescue the dislocation tooth by the ligation of utility arch strain is advanced in the groove by certain rule, the bracket that on each tooth, bonds.But clinically malposed tooth come into line differently, also random, often be difficult to the arch wire ligation is gone in the groove of each bracket.To this, often adopt two kinds of methods to solve clinically: the first adopts soft arch wire ligation to go into groove earlier, treat that transposition of teeth makes moderate progress after, by number changing thick and stiff arch wire into; It two is by bending the song of different shape on arch wire, strengthens arch wire elasticity, makes arch wire enter groove smoothly, treat that transposition of teeth makes moderate progress after, change straight thick and stiff arch wire into.Because the structural defective of bracket, make and frequently change arch wire clinically and increased the clinical position amount, also prolonged the clinical treatment time, bring inconvenience to clinical treatment.And because sub-ligation is gone in the groove under the arch wire, usually make the power of rescuing excessive, cause tooth pain discomfort.

Summary of the invention:

The purpose of this utility model is the horn mouth bracket that a kind of groove width of design diminishes gradually.

Technical solutions of the utility model are achieved in that a kind of horn mouth bracket, comprise base and the bracket seat that has groove fixed thereon, and the bracket seat outside offers ligature furrow, it is characterized in that the place, the exit or entrance of a clitch of groove offers horn-like enlarging.The groove structure that formation diminishes gradually from groove mouth to bottom land, because bell mouth shape groove throat width is bigger, arch wire can enter on each facing in the bracket groove smoothly clinically, when transposition of teeth is serious, arch wire can be introduced into place, the bell mouth shape exit or entrance of a clitch, along with the improvement of transposition of teeth, slip in the groove along the horn mouth inclined-plane gradually.

The utlity model has simple in structurely, clinical manipulation is convenient, because the width of bell mouth shape groove dwindles gradually, adjust the distortion of arch wire, produce the suitable power of rescuing and rescue malposed tooth, make to reduce clinically and replace arch wire, alleviate the clinical position amount, also shortened treatment time.And arch wire is that ligation is gradually gone in the groove, can make the power of rescuing and tooth mobile phase to steadily, is more suitable in orthodontic and alleviates tooth pain discomfort.

Below in conjunction with concrete legend this utility model is described further.

The specific embodiment:

With reference to Fig. 1 and Fig. 2, a kind of horn mouth bracket, comprise base 1 and the bracket seat 3 that has groove 2 fixed thereon, bracket seat 3 outsides offer ligature furrow 4, wherein 21 places, the exit or entrance of a clitch of groove 2 offer horn-like enlarging, have bigger fault-tolerant space, so that when the tooth dislocation is big, hold arch wire, and arch wire is slipped in the groove 2 gradually.And groove 2 bottoms of trench keep at least one can ccontaining side's arch wire the position, reach the need of final rectification.Fig. 1 is the twin bracket holder structure.

Claims

1, a kind of horn mouth bracket comprises base and the bracket seat that has groove fixed thereon, and the bracket seat outside offers ligature furrow, it is characterized in that the place, the exit or entrance of a clitch of groove offers horn-like enlarging.

2, horn mouth bracket according to claim 1 is characterized in that the groove bottom of trench keeps the position of the ccontaining side's arch wire of an energy at least.
