Abstract
The utility model discloses a torque orthodontics square edgewise wire (1) for adducting a tooth extraction space, which is consistent with the camber line of a dental arch, and is mainly applied to a stage of adducting front teeth and closing tooth extraction space by utilizing a sliding method of straight wire appliance (a straight wire bracket) in a tooth extraction case after teeth is leveled and arranged orderly. The section of an arch wire (1) is rectangular and consists of a front section and a rear section. Through the lingual root torque a of the front-section arch wire (2) (an area among lateral incisor consists of two lateral incisors and two central incisors), a groove (4) is clamped by the front-section arch wire which enters a groove, the front-section arch wire (2) and the groove (4) cannot generate relative displacement on a sagittal plane, the intersection angles of all edges of the section of the arch wire are 90 degrees. The intersection angles of the sections of the rear-section arch wire (3) (an area behind distal lateral incisors on two sides) are blunt, the arch wire is straight and has no torque, and keeps consistent with a buccal tube and a bracket groove. The torque of the front-section arch wire can avoid the occurrence of lingual root tipping (lingual crown tipping) during the adduction process of front teeth, so as to achieve whole furthest parallel movement in the overall adduction process of the front teeth. The rear-section arch wire has no torque and keeps certain space between the buccal tube and the bracket groove, so that the frictional force together with the groove can be reduced in the backward movement of the arch wire in the closed tooth extraction space.
Description
Technical field
This utility model relates to the metal square arch wire using in orthodontic, belongs to type medical instrument for dental use technical field, is specifically related to a kind ofly add torque correction side silk for interior receipts extraction of tooth space.
Background technology
In orthodontic therapy extraction cases process, after tooth leveling comes into line, utilize receipts labial teeth in straight wire appliance sliding scale to close the extraction of tooth space stage.The frictional force that now keeps the overall parallel of dental arch leading portion (labial teeth) and reduce buccal segment (backteeth) is Focal point and difficult point wherein, effectively solves these two problems and all can make orthodontic speed and effect obtain to take on a new look.
But at present in application straight wire appliance sliding scale closes the process of extraction of tooth space, be found to have following problem clinically: 1. in interior receipts labial teeth process, easily cause anterior teeth axle too uprightly even tongue incline, affect labial teeth interlock stable and attractive in appearance.2. back segment arch wire is very large at bracket and buccal tube internal resistance.3. sometimes need doctor to suppress in Upper Anterior Teeth corona to receive too much with torque pincers, but the number of degrees are difficult for grasping, can cause torque not or torque place arch wire is difficult for into groove.
Temporarily also there is no such this type of orthodontic bow-wire that can directly utilize in the market, front and back section designs for meeting difference in functionality needs, and leading portion is with torque, and back segment is not with torque.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, and provide a kind of mouth cavity orthodontic arch wire, more can meet than common correction metal side silk in the process of clinical practice straight wire appliance sliding scale pass extraction of tooth space: labial teeth holding torque parallel, between backteeth and arch wire, frictional force is little, slides freely.
For achieving the above object, the technical measures that this utility model adopts are: one consistent with dental arch camber line for interior receipts extraction of tooth space add torque correction side silk, formed by leading portion arch wire and back segment arch wire two parts.Arch wire leading portion is between two lateral incisors.At upper jaw arch wire leading portion, this has the approximately long 36-38mm in region of torque, and at lower jaw tooth leading portion, this has the approximately long 26mm in region of torque.(scope is between two lateral incisors to leading portion arch wire, comprise two lateral incisors and two central incisors) with root tongue to torque (being the torque of root of the tooth towards lingual direction), arch wire cross section is that each limit angle of cut is the rectangle of 90 degree, can clamp groove after making like this leading portion arch wire enter bracket; Back segment arch wire (both sides lateral incisor far away in later region) arch wire is straight, and not to be with torque, arch wire cross section be also rectangle but each limit angle of cut is justified blunt.
When three summits of arch wire cross section rectangle prop up three walls of bracket and reach while stablizing, now between arch wire long on one side and on straight silk bow supporting groove (or under) limit, form certain angle, this angle is identical with the lingual root torque of arch wire leading portion, and its angle value equals α (as Fig. 3).When arch wire is when (2) cross sectional dimensions is 0.017 × 0.025 inch, ∠ α is 12.48 ° as calculated; Arch wire is when (2) cross sectional dimensions is 0.018 × 0.025 inch, and ∠ α is 9.84 °; Arch wire is when (2) cross sectional dimensions is 0.019 × 0.025 inch, and ∠ α is 7.24 °; Arch wire is when (2) cross sectional dimensions is 0.020 × 0.025 inch, and ∠ α is 4.75 °; Arch wire is when (2) cross sectional dimensions is 0.021 × 0.025 inch, and ∠ α is 2.33 °.
Arch wire is NiTi or stainless steel, can bend by hand and also can pass through mould preformation.
This utility model compared with prior art has the following advantages:
1, four of the back segment side of arch wire silk corner angle circle is blunt, to reduce tooth frictional force between arch wire and buccal tube, bracket in moving process;
2, the leading portion of arch wire added point tongue to torque, avoid labial teeth that the incline tongue of coming of age of root lip occurs in interior receipts process and incline, make the labial teeth reach overall parallel to greatest extent in whole interior receipts process.
3, the design's arch wire has reduced doctor's labor intensity, has saved the clinical manipulation time, has guaranteed orthodontic effect.
