Abstract

A split-type slotted bearer for correcting the tooth dislocation is composed of a base and a slotted flange, which are matched by their concavo-convex structures and fixed together by adhesive or screw. Its advantages are precision correcting, little damage to tooth, easy operation, simple structure, and low cost.

Description

Split type bracket

The present invention relates to a kind of aid of straightening of teeth position deformity, particularly split type bracket.

In the prior art, for the odd-shaped rectification of tooth position, usually several brackets are bonded on row's tooth, dental arch filament is set in the cross recessed translot on each bracket, with the ligation silk dental arch filament is fixed on the bracket, utilize the elastic force on the dental arch filament, gradually the tooth of position deformity is corrected.Kept 1 year with keeper then, at present the bracket that uses by bracket at the bottom of and the bracket wing forms because bracket wing lesion ports transmucosal brings misery to the patient, and bracket wing structure complexity, be difficult to clean, the overlong time of wearing easily forms dental caries and periodontal disease.Present keeper has four kinds, and a kind of is removable retainer, and its plastics holder makes patient's discomfort in the oral cavity, and easily form oral mucosa and infect, a kind of is tongue side retention tab, and a kind of is tooth spring silk, both are bonded at tooth tongue side, only can keep

tooth

1,2,3, inaccessible maintenance effect, and difficulty cements, and easily comes off when chewing, and needs the acid etching facing during bonding, damage tooth, a kind of is the dental arch retention tab, needs acid etching tooth lip side once more, damage tooth during bonding.

The present invention will overcome above-mentioned defective exactly, designs a kind of new split type bracket.

Technical scheme of the present invention is: split type bracket by bracket at the bottom of and two absolute construction of the bracket wing form.Bottom surface at the bottom of the bracket is for being easy to agglutinating coarse structure, and there is a groove in the front at the bottom of the bracket; Bracket wing bottom surface is and the corresponding tongue of the groove in front at the bottom of the bracket, the front is a cross recess, there is the ligation groove side up and down, at the bottom of the bracket and the bracket wing coincide by concaveconvex structure, concaveconvex structure is polygon or arcs such as trapezoidal, rectangle, and the width of concaveconvex structure is the 0.5-3 millimeter, highly is the 0.2-1 millimeter, concaveconvex structure is bonding or use the peg fixation by binding agent, just forms split type bracket.The maintenance phase after the position deformity of tooth is corrected, shear the ligation groove of split type bracket with cutting nipper, separate with the bracket wing at the bottom of the bracket, will keep silk be set at the bottom of the bracket on and cement, by keeping the fixation of silk at the bottom of the bracket on several teeth, the position of dental arch is kept.

Advantage of the present invention and effect are to have replaced bracket and keeper in the past, and dental arch is rescued accurately, keep firmly, have solved the difficult problem that the lip side keeps, and the patient brings painful little, and injury of teeth is light, and is attractive in appearance, and behaviour does conveniently, and the present invention is simple in structure, and cost is low.

Embodiment:

As shown in Figure 1, 2, demonstration be the front structure of existing bracket, by at the bottom of the bracket 1 and the bracket wing 2 form.Shown in Fig. 3,4, demonstration be the front structure of split type bracket 3, by at the bottom of the bracket 4 and 5 two absolute construction of the bracket wing coincide by concaveconvex structure 6,4 fronts are concaveconvex structure 6 at the bottom of the bracket, the bottom surface is for being easy to agglutinating coarse structure; The bracket wing 5 bottom surfaces are the concaveconvex structure 6 relative with the groove in 4 fronts at the bottom of the bracket, the front is a cross recess, there is the ligation groove side up and down, at the bottom of the bracket 4 and the bracket wing 5 coincide by concaveconvex structure 6, concaveconvex structure 6 is polygon or arcs such as trapezoidal, rectangle, bonding or use the peg fixation by binding agent, just form split type bracket 3.As shown in Figure 5, what show is the use sketch map of straightening of teeth of the present invention, several split type brackets 3 are bonded on row's tooth, dental arch filament 7 is set in the cross recessed translot on each bracket, with ligation silk 8 dental arch filament 7 is fixed on the bracket, utilize the elastic force on the dental arch filament 7, gradually the tooth of position deformity is corrected.As shown in Figure 6, what show is the use sketch map that the present invention keeps dental arch, after the position deformity of tooth is corrected, shear the ligation groove of split type bracket 3 with cutting nipper, 4 separate with the bracket wing 5 at the bottom of the bracket, will keep silk 9 to be set at the bottom of the bracket on 4 and cement, at the bottom of the bracket on several teeth 4, by the fixation of the maintenance silk 9 that cements, the position of dental arch is kept.

Claims

1, a kind of split type bracket of straightening of teeth position deformity is characterized in that at the bottom of split type bracket is by bracket and two absolute construction of the bracket wing are formed, and there is a groove in the front at the bottom of the bracket; Bracket wing bottom surface is and the corresponding tongue of the groove in front at the bottom of the bracket, at the bottom of the bracket and the bracket wing coincide by concaveconvex structure, concaveconvex structure is polygon or arcs such as trapezoidal, rectangle, and concaveconvex structure is bonding or use the peg fixation by binding agent, just forms split type bracket.

2, at the bottom of the bracket according to claim 1 and the bracket wing, it is characterized in that at the bottom of the bracket and the bracket wing on the width of concaveconvex structure be the 0.5-3 millimeter, highly be the 0.2-1 millimeter.

3, at the bottom of the bracket according to claim 1 and the bracket wing, it is characterized in that at the bottom of the bracket and the bracket wing on concaveconvex structure by the peg fixation.
