Abstract
The utility model provides a just abnormal local clearance expander. Just abnormal local clearance expander cooperation tooth is fixed to be rescued the ware and acts on tooth surface, its characterized in that: including clearance extension spring coil and setting up the left and right support arm of expanding the spring coil both sides in the clearance, linking arm and left and right bracket connection that the spring coil both sides formed through buckling are respectively expanded downwards to the clearance, and it is used for fixing the crotch of being connected of rescuing the ware with the tooth to buckle respectively to form at the other end of left and right support arm. The utility model discloses a principles of design according to zone circle perpendicular qu kaizhan clearance forms for the carrying out of less clearance in the denture conveniently aligns crowded denture, can be directly needs carry out the clearance stablize the arch wire on assemble, the extension space generally uses 4 -8 after week, can obtain to align the clearance that the denture needs. The the other work of chair time is shortened, through the clinical practice, the utility model discloses can obtain the space of rescuing of ideal.
Description
Technical field
This utility model belongs to orthodontic technical field, specifically a kind of correction local gap expander.
Background technology
Along with people also more and more pay attention to beautiful teeth, people to the research of tooth fixed orthodontics also gradually deeply, orthodontic technology (also known as orthodontics) is also developing gradually, and correction mainly studies the Etiologic Mechanism of patho-occlusion, diagnostic analysis and prevention and therapy thereof.
In correction clinically for the denture of slight crowding, expansion gap is the conventional means in therapeutic process.Rescuing preliminary clinical utilizes the elasticity of soft titanium-nickel wire carry out space that dental arch obtains aligning.Treatment stage then usually overlaps and pushes away spring on the main arch wire of correction, utilizes time tension force of Compress Spring to carry out moving teeth and carries out gap, for crowded denture provides the space of straightening of teeth.Phase after the treatment, reverse if there is individual teeth, local congestion is recurred, and adopts according to a conventional method from soft to firmly, from carefully to slightly, from circle to the arch wire using priciple of side, must require great effort time-consuming, incur loss through delay and rescue the course for the treatment of.
Summary of the invention
This utility model is for the deficiencies in the prior art, a kind of correction local gap expander is provided, this expander is that the principle design of carrying out gap according to vertical helical loop forms, this expander may be used for more closely spaced in denture development, conveniently come into line crowded denture, desirable effect can be reached, greatly reduce the chair other working time.
The technical scheme that this utility model provides: described a kind of correction local gap expander, tooth fixed appliance is coordinated to act on exterior of teeth, it is characterized in that: described local gap expander comprises gap expansion spring coil and is arranged on the left and right supporting arms of expansion spring coil both sides, gap, expansion spring coil both sides, gap are connected with left and right supporting arms respectively by the linking arm be bent to form downwards, are bent to form the crotch for the connection with tooth fixed appliance respectively at the other end of left and right supporting arms.
The further technical scheme of this utility model: the crotch in two linking arms of described gap expansion spring coil, left and right supporting arms, joint gap expansion spring coil and left and right supporting arms and left and right supporting arms is bent to form by an one metal wire.
This utility model is technical scheme preferably: described left and right supporting arms is horizontal, and two linking arms of left and right supporting arms and joint gap expansion spring coil and left and right supporting arms are symmetrical.
This utility model is technical scheme preferably: the minimum point that two linking arms that joint gap expands spring coil and left and right supporting arms bend downwards is lower than the height of left and right supporting arms.
This utility model is technical scheme preferably: the crotch of described left and right supporting arms outer end is all bend from inside to outside to form.
This utility model is technical scheme preferably: the crotch in two linking arms of described gap expansion spring coil, left and right supporting arms, joint gap expansion spring coil and left and right supporting arms and left and right supporting arms is that the correction special Australia silk of employing 0.016 inch or 0.018 inch bends and forms.
This utility model is that the principle design of carrying out gap according to vertical helical loop forms, carry out for more closely spaced in denture, conveniently come into line crowded denture, can directly assemble on the stable arch wire needing to carry out gap, extending space, after general use 4-8 week, the gap that aligning needs can be obtained.Greatly reduce the chair other working time, through clinical practice, this utility model can obtain desirable rescues space.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.A kind of correction local gap expander as shown in Figure 1, tooth fixed appliance 5 is coordinated to act on exterior of teeth, it is characterized in that: described local gap expander is bent by the correction special Australia silk of one 0.016 inch or 0.018 inch to form, Australia's silk is the special arch wire of correction, is the special arch wire of Australia.In the middle of Australia's silk, specifically first upwards bend 2-3 enclose formation gap expansion spring coil 1, then two ends gap being expanded spring coil 1 respectively under be bent to form the linking arm 4 of left and right up concave type, the minimum point that two linking arms 4 bend downwards is lower than the level height of Australia's silk, again two linking arms 4 are upwards bent to Australia's silk level height, and form a horizontal left side to both sides horizontal-extending, right support arm 2, 3, last on a left side, right support arm 2, the outer end of 3 forms the crotch 6 being used for being connected with tooth fixed appliance 5 respectively from inside to outside, in installation process, directly from inside to outside can hang over the square silk of appliance or justify on silk, ligation maintenance circle, lay operation convenient, connect firm stable more.Describedly bend gap expander left and right supporting arms 2,3 and joint gap expansion spring coil 1 is symmetrical with two linking arms 4 of left and right supporting arms 2,3.
This utility model in use, maxillary teeth surface can be arranged on, also mandibular teeth surface can be arranged on, during concrete installation as shown in Figures 2 and 3, first tooth fixed appliance 1 is installed, then this utility model is assembled to maxillary teeth surface or mandibular teeth surface engagement dental appliance be used for expanding two interdental gaps.When correction local gap expander of the present utility model is installed, gap is expanded spring coil 1 and insert position between two teeth that need to expand from circle silk or the gap of square silk 7 and dental surface, specifically insert from the direction of root of the tooth cuspad, by circle silk or square silk 7, spring coil 1 is expanded in gap after insertion to fix, the linking arm 4 of the left and right sides is placed in the side of tooth near root of the tooth, by a left side, right support arm 2, 3 are fitted in the dental surface of tooth fixed appliance 1 near gingiva side, and by a left side, right support arm 2, 3 two ends press down, the hook 6 at its two ends is made to hang upside down on circle silk or square silk 7, and by many tied silks 8 by a left side, right support arm 2, 3 band together with fixing teeth appliance 5.This utility model can directly assemble on the stable arch wire needing to carry out gap, gap is utilized to expand spring coil 1 and left and right supporting arms 2,3 liang expansion two interdental spaces, general use, after 4 ~ 8 weeks, can obtain the gap that aligning needs, and greatly reduces the chair other working time.
