Abstract
The utility model discloses an orthodontic bracket, which comprises a bracket body and a substrate plate, wherein the bracket body and the substrate plate are integrally formed by casting, and a plurality of convex ribs are integrally formed by casting on the bottom surface of the substrate plate bonding to a facing. The technical scheme is that: the whole bracket body is integrally formed by precision casting to overcome the defects of the prior art, and the risk of the loose weld of the bracket body and the substrate plate and the impact of complex soldering material components on the human body do not occur; the convex ribs are integrally formed by casting on the bottom surface of the substrate plate, thereby ensuring the bonding effect of the substrate plate of the bracket and the facing; the tooth position marks are directly cast on the bottom surface of the substrate plate, so that the utility model has the advantages of high production efficiency, low cost, clear mark and the like, and facilitates doctors to quickly identify to bond the bracket to the correct position.
Description
Technical field
This utility model belongs to mouth cavity orthodontic material field, particularly relates to a kind of orthodontic bracket.
Background technology
As shown in Figure 1 and Figure 2, tooth section net bottom orthodontic bracket is the important component part of mouth cavity orthodontic fixed appliance, comprise supporter groove 1 and substrate plate 2 two parts, the bottom surface of substrate plate 2 adopts special bonding agent and facing to be adhesively fixed, supporter groove 1 is provided with for arch wire by groove 12, by tie wings 11 snappings on ligature loop and the supporter groove 1 arch wire is fixed on the bracket, the power of rescuing of arch wire is delivered to tooth by bracket in the orthodontic treatment process of denture, makes tooth produce moving of expection.
Every cover bracket has 20, belongs to four zones up and down of human body denture, because the tooth on each tooth position is not of uniform size, corresponding bracket is also different.Therefore, make just abnormal doctor can conveniently distinguish each tooth position bracket, manufacturer's method commonly used at present is that gum adopts different colors up and down to an identification marking in supporter groove surface tie wings is far away.Though adopt color differentiating to distinguish up and down, the bracket of the same area mixes, the medical worker also is difficult to distinguish for the moment the bracket of each tooth position.Particularly come off easily, cause using clinically very inconvenient with color mark.Second kind of tooth bit-identify method is the tooth position that indicates every bracket correspondence on the substrate plate of bracket with the method for laser marking, and the weak point of this method is the laser marking location difficulty, causes efficient low-cost high, and producer uses few.
Existing orthodontic bracket is taked two kinds of ways for increasing the adhesive strength of bracket substrate plate and tooth: the one, cut out dovetail groove with wire cutting method in the bottom surface that substrate plate 2 and facing are pasted, as shown in Figure 1; The 2nd, supporter groove 1 is welded with substrate plate 2, and adopts method formation network structure such as welding in the bottom surface of substrate plate 2.But these two kinds of methods are not very perfect, and the former separates bonding agent and influences adhesive strength, and the latter also exists the risk of body and substrate plate sealing-off and solder component complexity to produce harm to human body.
Summary of the invention
In order to solve the bonding problem of above-mentioned bracket substrate plate, the purpose of this utility model provides a kind of orthodontic bracket, adopt supporter groove and substrate plate integrally formed, and at the integrally formed convex tendon in the bottom surface of substrate plate, thereby the adhesive effect of assurance bracket substrate plate and facing.
To achieve the above object, this utility model has adopted following technical scheme:
A kind of orthodontic bracket comprises supporter groove and substrate plate, and described supporter groove and substrate plate integrally casting are shaped, and integrally casting is formed with a plurality of convex tendons on the bonding bottom surface of described substrate plate and facing.
As preferably, above-mentioned a plurality of convex tendons radially distribute.
The convex tendon cross section can be rectangle or other shapes, and still, preferably above-mentioned convex tendon cross section is the narrow concavity of the wide root in top.The combination that can guarantee bonding agent and substrate plate like this is firm.
As preferably, the part with respect to female protruded of above-mentioned convex tendon for being recessed to form by described substrate plate bottom surface portions, described convex tendon surrounds described female.
As preferably, above-mentioned female is linked to be whole piece.
As preferably, integrally casting is formed with tooth position identification marking on the bonding bottom surface of above-mentioned substrate plate and facing.
As preferably, above-mentioned tooth position identification marking is the figure notation of projection. certain described tooth position identification marking also can fall in.
As preferably, above-mentioned tooth position identification marking is positioned at the central authorities of described a plurality of convex tendons.
Because the technical program forms the hot investment casting of whole supporter groove one, above-mentioned the deficiencies in the prior art have been overcome, do not exist the risk and the solder component complexity of supporter groove and base plate sealing-off may be to the influence of human body, and at the integrally formed convex tendon in the bottom surface of substrate plate, thereby the adhesive effect of assurance bracket substrate plate and facing.And, on the substrate plate bottom surface, directly cast out tooth position labelling, have advantages such as production efficiency height, cost is low, labelling is clear, be convenient to doctor's quick identification, bracket is adhered to correct position.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of orthodontic bracket as shown in Figure 3, Figure 4, comprise supporter groove 1 and substrate plate 2, supporter groove 1 is provided with for the tie wings 11 of arch wire by groove 12 and hitch ligature loop, described supporter groove 1 and substrate plate 2 integrally castings are shaped, and integrally casting is formed with a plurality of convex tendons 22 on described substrate plate 2 and the bonding bottom surface of facing.
In the present embodiment, described a plurality of convex tendon 22 radially distributes, described convex tendon 22 cross sections are the narrow concavity of the wide root in top, the part with respect to female 24 protrusions of described convex tendon 22 for being recessed to form by described substrate plate 2 bottom surface portions, described convex tendon 22 surrounds described female 24, described female 24 is linked to be whole piece, makes bonding agent become a slice not cut apart the assurance adhesive effect.Like this, bracket is when being subjected to the outside destroy of a plurality of directions, because radiation falls recessed structure to the extremely strong mechanical fixing effect of resin, special bonding agent is difficult for from peeling off in conjunction with the most weak substrate plate bottom surface, thereby strengthened the adhesive strength of bracket substrate plate and facing, that has avoided greatly that bracket is subjected to that the external force of a plurality of directions causes comes off.
In the present embodiment, integrally casting is formed with tooth position identification marking on described substrate plate 2 and the bonding bottom surface of facing, and described tooth position identification marking be protruding figure notation 23, and described tooth position identification marking is positioned at the central authorities of described a plurality of convex tendon 22.These figure notations 23 can be consistent with above-mentioned convex tendon 22 heights of projection, also can only guarantee clear identification a little less than above-mentioned convex tendon 22 heights of projection.
