Abstract

The utility model provides a combined titanium steel arch wire used for correcting the tooth deformity, which is characterized in that the titanium arch wire is used on the corrected part of the tooth deformity, and the steel arch wire is used on the part of fixation. The utility model overcomes the defects and combines the advantages of the titanium arch wire and the steel arch wire. According to the section of the tooth deformity, the combined titanium steel arch wire can be used for correcting the deformity of front teeth, rear teeth of both sides, and rear teeth of one side. The utility model can put the tooth deformity in order in the process of teeth correction, leads the corrected teeth to move continuously according to the designed order and avoids reverse correction, does not need to be changed in a short time, enhances the arrival rate and the supporting power of the out-of-order teeth, enhances the stabilization of adjacent teeth, and has an excellent effect of correction.

Description

Combined titanium steel arch wire

This utility model is applicable to a kind of correction apparatus that hospital's tooth (oral cavity) section correction deformity tooth is used.

Hospital rescues tooth deformity at present, and commonly used is that fixed appliance is mainly used light line of force technology.In recent years, use the commonplace of high gentle line technology development, what fixed appliance adopted is steel arch wire or titanium arch wire.Find that in clinical practice steel arch wire rigidity is strong, flexible poor, is unfavorable for coming into line of tooth in rescuing process,, and need often to change arch wire, increased trouble to patient and doctor particularly to the crowded tooth deformity of severe; Titanium arch wire, flexible strong and poor rigidity, finding in clinical practice crowdedly has a good effect to what come into line labial teeth.But, since ligation on tooth after, tangible change can take place in the arch wire form, " contrary correct " occurred, has not only changed the power that acts on each tooth, and, form that can not the former dental arch of better controlled.

At above-mentioned situation, this utility model provides a kind of novel titanium steel compound bow silk, and it has overcome the shortcoming of above-mentioned two kinds of arch wires and has drawn the two advantage, has the good power of rescuing, and therapeutic effect is remarkable, patient satisfaction.

With titanium steel combination arch wire sketch map, 1 is steel wire, the 2nd among the figure, titanium silk, the 3rd, sleeve pipe.

Fig. 2 corrects both sides backteeth mistake

With titanium steel combination arch wire sketch map.

Fig. 3 corrects one-sided backteeth mistake

With titanium steel combination arch wire sketch map.

Fig. 4 is that two kinds of arch wires overlap sketch map up and down.

Fig. 5 is two kinds of (titanium, steel) arch wire overlap joint sectional schematic diagrams.

The utility model is to realize like this (such as Fig. 1): at first contrast steel (or titanium) arch wire shape by designing requirement, intercept two sections steel wires and one section titanium silk, the titanium silk is curved curve shape, then the joint with steel wire (1) and titanium silk (2) inserts in the sleeve pipe (3), with pliers reinforcing or external force extruding sleeve pipe being flattened (such as Fig. 5) forms, so not only in conjunction with firm, the primary characteristic that also still can keep titanium silk, steel wire conforms to clinical requirement through this kind of test of many times Combined titanium steel arch wire. Appearing at the tooth middle part by clinical observation most of patients deformity teeth is near the front tooth, and therefore, it is titanium silk (correction deformity tooth position) that Combined titanium steel arch wire is generally all made the middle part, and two ends are the rectification labial teeth mistake of steel wire (fixed position)Combined titanium steel arch wire (such as Fig. 1). Also design rectification both sides backteeth mistake by same designWith Combined titanium steel arch wire (middle part steel wire, position, both sides are titanium silk such as Fig. 2); If correct the unilateral posterior teeth mistake

With the combination arch wire, middle part and a side of not correcting adopt steel wire, and a side of rectification adopts titanium silk (such as Fig. 3).

This utility model is compared with existing steel (or titanium) arch wire: compare with the titanium arch wire, titanium steel combination arch wire can be eliminated the power that acts on and rescue on the adjacent normal tooth of tooth, make the tooth of rescuing continue mobile can having avoided " the contrary rectification ", rather than form alternately mobile with adjacent teeth by the arrangement form in our design; Compare with the steel arch wire, use titanium steel combination arch wire act on the tooth insisting on continuous and evenly, tooth continue to move to be unlikely and makes tooth stressed excessive and cause damage, do not need the short time to change arch wire, therefore, use titanium steel combination arch wire not only can control the anchorage tooth in the horizontal and vertical directions better, reduce the mobile chance of grinding one's teeth in sleep, and can make the better of the power of the rescuing performance that acts on the labial teeth, thereby the arrival rate of malposed tooth and Zhi Kangli, adjacent teeth have been improved Fixed degree, thus the good power of rescuing had, evident in efficacy.

Below in conjunction with accompanying drawing an embodiment is described: select by Fig. 1 shape that diameter is 0, the steel wire of 30-0,50MM for use, intercept two sections, general every segment length 3,5-5,0CM, with selected diameter be 0,30-0,50MM titanium silk, general intercepting 1,5-4,0CM length, then an end that will connect is inserted set rustless steel pipe box (internal diameter be 0,8MM) overlap joint (as Fig. 4) up and down, insert behind the sleeve pipe with the afterburning folder of pliers flat or external force extruding (as Fig. 5) and form titanium steel and make up arch wire.Can also can make according to the needs of patient's tooth deformity equally and correct both sides backteeth mistake

Make up arch wire (Fig. 2) with titanium steel, correct one-sided backteeth mistake

Make up arch wire with titanium steel.

Claims

1, a kind ofly rescue the titanium steel combination arch wire that tooth deformity uses, it be is characterized in that by the novel arch wire that steel wire (1), titanium silk (2), sleeve pipe (3) are formed:

The connection of A, two kinds of (titanium, steel) arch wires is earlier the arch wire joint that will connect to be inserted sleeve pipe (upper and lower overlap joint) then to form with pincers or external force extruding, does not only combination so firmly, also still can keep the primary characteristic of titanium silk, steel wire.

What be used in the rectification position in B, the titanium steel combination arch wire is the titanium silk, and fixed position is a steel wire.

2, titanium steel combination arch wire according to claim 1 is characterized in that wherein steel wire and sleeve pipe are the nickel chromium stainless steel material.
