Abstract
The utility model belongs to a medical device, while in correcting malposition and malformation, reinforces the anchorage of an anchorage molar and prevents the anchorage molar from shifting. The utility model includes a band, a fixed towing hook, and a buccal tube, a rotation towing hook, a rotation axis, an occlusal rod and an occlusal pad. When the band of the utility model is worn on the anchorage tooth, the anchorage rob is extended to the part of tooth occlusal surface, and a 2mm gap is formed between the occlusal surface of teeth and the anchorage rob. The moved tooth is connected with the rotation towing hook of the utility model by an elastic rubber band or a nickel titanium coil springs. When the anchorage tooth is not occlusal, the length of the elastic rubber band or the length of the nickel titanium coil springs is in stress but not be stretched, is not in the status of traction force. When the anchorage tooth is occlusal, the part of the anchorage rob which is extended to the tooth occlusal surface, is moved to the occlusal surface under the stress of the occlusal force, and the rotation towing hook is clockwise rotated, the elastic rubber band or the nickel titanium coil springs is extended, then the traction tooth is moved under stress. Under such condition, the anchorage molar is occlusal and can not be moved. In this way, the anchorage molar is prevented from moving.
Description
Affiliated technical field
This utility model belongs to medical apparatus and instruments, particularly be a kind of wrong abnormity orthopedics process that is used for, the traction tooth strengthens anchorage dental branches drag when moving, and prevents the device of anchorage tooth displacement.
Technical background
At present, in rescuing the odd-shaped process of wrong , when the anchorage tooth of mobile tooth needs the strongest anchorage, strengthen anchorage, prevent that the method for anchorage tooth displacement from having two kinds, be i.e. face-bow appliance and implant anchorage.The face-bow appliance is by extending in the mouth outside the mouth, and the patient has very intensive uncomfortable sensation; The patient will wear head cap, brings great inconvenience for normal life and social activity.And the face-bow improper use also can damage the patient.Implant anchorage need be implanted implantation body in patient's the jawbone with the method for operation, and operation is complicated, and cost is higher, but also problem such as may cause infection, implantation body to move to come off.
Summary of the invention:
The purpose of this utility model can overcome above-mentioned shortcoming, safety, reliable, convenient, with low cost prevents and treats the appliance that the anchorage tooth moves.
The purpose of this utility model is realized by following technical scheme, specifies as follows:
This utility model is made up of band, fixed traction ditch, buccal tube, rotation traction traction hook, rotating shaft, interlock bar, occlusal pad.The rotation traction traction hook is connected with buccal tube by rotating shaft with the interlock bar, and the interlock bar extends to the part socket occlusal pad of anchorage facies occlusalis dentis.
When band of the present utility model is worn into the anchorage tooth, the interlock bar extend to the anchorage occlusal surfaces of teeth part and on the 2mm gap of having an appointment between the occlusal pad that covers and the occlusal surfaces of teeth.The tooth that is moved links to each other with rotation traction traction hook of the present utility model by elastic force elastic tape or nickel titanium coil spring.When the not interlock of anchorage tooth, elastic force elastic tape or nickel draw the length that pushes away spring to be in anxiety and not by stretching, not have the pull strength state.When the interlock of anchorage tooth, the interlock bar extend to occlusal surfaces of teeth part and on the stressed occlusal surface that moves to of occlusal pad that covers, the rotation traction traction hook rotates backward, elastic force elastic tape or nickel titanium coil spring elongation are pulled that tooth is stressed to be moved.At this moment, the anchorage tooth is in interlocking pattern, can't move.Like this, just prevented the displacement of anchorage tooth.And the size of pull strength can be regulated control by the quantity of elastic force elastic tape and the coefficient of elasticity of coefficient of elasticity or nickel titanium coil spring.This utility model is worn with convenient, safety, and clinical manipulation is simple.After drawing mobile tooth with this utility model and finishing, can also rotate and withdraw from rotating shaft, remove interlock bar and rotation traction traction hook, more simplified the structure of appliance, made things convenient for Clinical Application.
Description of drawings
Below in conjunction with accompanying drawing and example this utility model is further specified.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that this utility model is worn the sketch map into the anchorage tooth
Fig. 3 and Fig. 4 are user mode sketch maps of the present utility model
Fig. 5 is that this utility model finishes in traction, the structural representation behind dismounting rotation traction traction hook and the interlock bar
Among the figure, the 1st, band, the 2nd, fixed traction hook, the 3rd, rotation traction traction hook, the 4th, buccal tube, the 5th, rotating shaft, the 6th, interlock bar, the 7th, occlusal pad.In addition, A is the anchorage tooth, and B is moved tooth, C be the anchorage tooth to the tooth, the 8th, arch wire, the 9th, be moved the bracket of tooth, the 10th, the traction extension spring.
The specific embodiment:
Illustrate that by Fig. 3 and Fig. 4 this utility model work operating position is as follows:
During use, for example wear this utility model, draw mobile tooth B with anchorage tooth A.Be connected nickel titanium coil spring between rotation traction traction hook and the bracket that is moved tooth.The length of spring is: during not interlock of anchorage tooth A, spring is in anxiety and the state of tractive distortion not.(Fig. 3)
When anchorage tooth A interlock, the occlusal pad 7 of Occlude tractor moves to the occlusal surface of anchorage tooth A, and rotation traction traction hook 3 rotates backward, and nickel titanium coil spring is subjected to tractive elongated, and tooth B is stressed to be moved.(Fig. 4)
After drawing mobile finishing, can rotate and withdraw from rotating shaft 5, remove rotation traction traction hook 3 and interlock bar 6, make the structure of buccal tube simpler, wear with more comfortable, convenient.(Fig. 5)
Claims (4)
1, Occlude tractor is made up of band, fixed traction ditch, buccal tube, rotation traction traction hook, rotating shaft, interlock bar, occlusal pad.Its characteristics are: rotation traction traction hook, interlock bar link by rotating shaft and buccal tube.
2, Occlude tractor according to claim 1 is characterized in that: the interlock rod bending extends to occlusal surfaces of teeth.
3, Occlude tractor according to claim 2 is characterized in that: the interlock rod bending extends to the part socket occlusal pad of occlusal surfaces of teeth.
4, Occlude tractor according to claim 1 is characterized in that: when the interlock rod bending extended to the part of occlusal surfaces of teeth and gmatjpdumamics that occlusal pad is subjected to vertical direction, the rotation traction traction hook rotated, and produced the pull strength of horizontal direction.
