Abstract
The utility model discloses an extension push tooth move bracket component. The bracket component is provided with a pair of slippery poles and a pair of spiral driving springs which is used with the main arch wire and bracket of the orthodontic fixed appliance. The front end of the slippery pole is provided with a retention traction cap, and the apex part of the end stretches out of the retention traction tap to for a drawing hook, the two slippery poles pass through the opposite retention traction cap to keep slithery connection separately, and can make location through the ligation wire winding on drawing hook, the rear end of the slide pole is provided with the position circle hook. The spiral driving spring and the position circle hook of the slippery poles are arranged on the main arch wire in an order, rear end of the spiral driving spring is closely clung to the bracket of the moved tooth, and the position circle hook of the slippery pole is closely clung to the front end of the spiral driving spring. The utility model can not only exert correcting strength to the moved tooth constantly, but also can adjust the strength accurately, and have no adverse effect to the anchorage, and the operation is easy and reliable.
Description
Technical field
This utility model relates to the medical apparatus and instruments in the mouth cavity orthodontic specialty, refers to that particularly a kind of telescopic tooth that pushes away that is used with the mouth cavity orthodontic fixed appliance far moves carriage assembly.
Background technology
The mouth cavity orthodontic fixed appliance is one of main apparatus that adopts in the present mouth cavity orthodontic clinical practice.Rescue case for exodontia, generally need push away canine tooth and move backward, bigger to the anchorage influence.In order to protect anchorage, prevent that as the reach of the backteeth of anchorage just abnormal doctor usually is provided with to open and pushes away canine distal apart from helical spring and move greatly on the fixed appliance master arch wire between canine tooth.But adopt the device of this kind structure, can not continue constantly to the application of force effect of pushing away tooth, main arch wire need be disassembled during further consultation, change helical spring, give the canine tooth reinforcing again, it is very inconvenient to operate.Rescue case backward for the tooth of turning a millstone, grind one's teeth in sleep far move after, also need to push away second bicuspid, first bicuspid, canine tooth and move backward, with closing gap, interior receipts labial teeth.But its push unit is not still deviate from the set pattern of said structure.The just abnormal doctor who has adopts the head cap face-bow to push away canine distal and moves; though the head cap face-bow can satisfy the protection problem of anchorage preferably; but the patient can only wear in bed; the height of patient's cooperate degree directly has influence on the quality of rectifying effect; it should use also is very inconvenient, and rectifying effect has uncertainty.The just abnormal doctor who also has adopts the fixedly push rod that is installed on the main arch wire and spiral to push away spring and pushes away canine distal and move, but this structure can only finely tune the application of force effect of pushing away tooth, still need to dismantle repeatedly, and it is consuming time to require great effort inefficiency.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of telescopic tooth that pushes away that is installed on the mouth cavity orthodontic fixed appliance far to move carriage assembly, this carriage assembly is to the both sustainable power of rescuing that applies of passing tooth, can accurately regulate application of force size again, and anchorage is had no adverse effects convenient and reliable operation.
For realizing this purpose, the designed telescopic tooth that pushes away of this utility model far moves carriage assembly, has a pair of sliding bar and a pair of spiral that uses that match with the main arch wire of mouth cavity orthodontic fixed appliance and bracket and pushes away spring.The front end of this sliding bar is provided with a maintenance traction casing, and the top tip part that this end stretches out the maintenance traction casing divide to form a hook, and the maintenance traction casing that two sliding bars pass the other side respectively is slidingly connected, and can be by being wrapped in the ligation silk location on the hook; The rear end of this sliding bar is provided with maintenance circle hook.The maintenance circle hook that this spiral pushes away spring and sliding bar is installed on the described main arch wire successively, and spiral pushes away the rear end of spring and is close to the bracket of being passed on the tooth, and the maintenance circle hook of sliding bar then is close to the front end that spiral pushes away spring.
Advantage of the present utility model is: designed a pair of sliding bar is connected to become telescopic passing support by the maintenance traction casing on it, by the maintenance circle hook on it be installed in a pair of spiral on the appliance master arch wire and push away spring and organically combine, and only prick silk and can accurately adjust the power value size that spiral pushes away spring by a root knot, thereby can continue to give consistently the tooth passed afterburning and do not need to dismantle repeatedly device such as appliance, clinically be used for canine tooth, first and second bicuspidal passing is very convenient reliable.Simultaneously; mainly act on the tooth of being passed because above-mentioned sliding bar and spiral push away the thrust of spring; backteeth as anchorage is not produced forward pulling force; so carriage assembly can effectively be protected anchorage; being specially adapted to exodontia and rescuing case, also is that the tooth of turning a millstone is rescued the strong corollary apparatus that case enters second phase treatment backward.
Description of drawings
Fig. 1 is a kind of telescopic structural representation that tooth far moves carriage assembly that pushes away;
Fig. 2 is used to pass the view of first bicuspid for this carriage assembly.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail:
The telescopic tooth that pushes away shown in the figure far moves carriage assembly, has a pair of arc sliding bar 9 and a pair of NiTi spiral that uses that match with the main arch wire 6 of mouth cavity orthodontic fixed appliance and bracket 7 and pushes away spring 1.The front end of arc sliding bar 9 is welded with maintenance traction casing 3, and the top part that this end stretches out maintenance traction casing 3 has 2mm long approximately, forms hook 8.The maintenance traction casing 3 that two arc sliding bars 9 pass the other side respectively is slidingly connected, and ligation silk 5 location that can be 0.25mm by a diameter that is wrapped on the hook 8.The rear end of arc sliding bar 9 is bent to maintenance circle hook 2.Snare is on main arch wire 6 successively for the maintenance circle hook 2 that the NiTi spiral pushes away spring 1 and arc sliding bar 9, and the NiTi spiral pushes away the rear end of spring 1 and is close to the bracket of being passed on first pair of tooth 7, and 2 on the maintenance circle hook of arc sliding bar 9 is close to the front end that the NiTi spiral pushes away spring 1.Simultaneously, also be wound with a located lateral sheet 4 on a pair of arc sliding bar 9 or on a pair of arc sliding bar 9 and the main arch wire 6, firm to guarantee their location, unlikely loosing taken off.
This is telescopic when pushing away tooth and far moving carriage assembly and use, with ligation silk 5 that the hook 8 of a pair of arc sliding bar 9 front ends is fastening to centre gathering and ligation, this promptly can move backward to arc sliding bar 9, make the maintenance circle hook 2 extruding NiTi spirals of its rear end push away spring 1, the NiTi spiral that has been compressed pushes away spring 1 can force first pair of tooth thereafter far to move backward.Each when increasing thrust, only need further ligation silk 5 is tightened up get final product, and needn't dismantle assembly such as fixed appliance, clinical practice is very convenient reliably.
