Abstract
The invention belongs to the field of orthodontic medical devices, and particularly relates to a memory alloy ligation asymmetrical dual-wing interactive self-ligating bracket. The self-ligating bracket comprises a bracket main body, a ligation ring and orthodontic wires, wherein the bracket main body is provided with asymmetrical ligation wings and grooves in near, far and middle directions; through holes into which the ligation ring are allowed to be embedded are designed in the ligation wings; the ligation ring is made by bending a memory alloy wire of a certain size; when the ligation ring is dragged, the ligation ring is deformed and enlarged, and can cross the ligation rings; when the ligation ring is released, the ligation ring recovers to an original shape to realize a self-ligating function. When the ligation ring is embedded into clamping grooves in different positions on one side of each ligation wing, gaps among the orthodontic wires of different specifications and models can be adjusted to realize the interactive function of the self-ligating bracket. By adopting the memory alloy ligation asymmetrical dual-wing interactive self-ligating bracket, the application range of the memory alloy in the field of self-ligating brackets for orthodontic treatment is fully extended. The memory alloy ligation asymmetrical dual-wing interactive self-ligating bracket has the characteristics of high operability and capability of controlling the gap between each orthodontic wire and the self-ligating bracket.
Description
Technical field
Patent of the present invention belongs to mouth cavity orthodontic medical instruments field, and in particular to a kind of memorial alloy ligatures asymmetric double-vane
Interactive locking bracket.
Background technology
The low force that appears as of locking bracket is rescued there is provided possibility, and in the market locking bracket has passive type structure, master
Dynamic formula structure and interactive structure.At present concordance thinks, passive type locking bracket has bright rescuing early stage tooth and come into line the stage
Aobvious treatment advantage, this is because passive type locking bracket is built into slide lock tabs, slide lock tabs with rescue the circle that early stage is used
There is gap between the correction silk of section, effectively reduce the frictional resistance that correction silk slides in bracket, it is to avoid frictional force is supported
The side effect of pin Orthodontic force, improves and rescues efficiency.There is contact between the built-in alligator clamp of active locking bracket and correction silk, two
Interaction force between person is conducive to the accurate expression torque in locking bracket of correction silk.Interactive locking bracket combines passive
Formula, active advantage, such as Germany Forestadent design fragment structure in different dental, labial teeth area using it is active oneself
Lock bracket, it is ensured that the three-dimensional data such as the torque in labial teeth area is controlled, backteeth area uses passive type locking bracket, can make full use of again low
Frictional force principle realizes correction silk in backteeth area slidably.
At present clinically widely used locking bracket is mainly the passive type locking bracket with slide lock tabs, band alligator clamp
Active locking bracket.Passive type locking bracket with slide lock tabs effectively creates low friction environment rescuing early stage,
Be particularly conducive to tooth to come into line, but most passive type locking bracket rescue the later stage give orthodontist it is limited rescue handss
Section, can not effectively provide the accurate expression of torque.Active locking bracket connects due to carrying alligator clamp with the generation of correction silk
Tactile stress, expression torque effect strengthens, but spring clamping structure can not effectively meet multiple switching manipulation.
The super elastic characteristics that memorial alloy has are widely used in bio-medical field, super-elasticity be under external force,
With many recoverable force ability bigger than common metal, i.e., the big strain produced in loading procedure can recover former with unloading
Shape.Such as super-elastic NiTi alloy wire for correcting shape of tooth, the effective straightening of teeth of ability restored using it, super-elastic NiTi is closed
The features such as golden implantable intravascular support utilizes super-elasticity, shape memory, the biocompatibility of itself, effective support stenosis occlusion
Section blood vessel.
The content of the invention
It is an object of the invention to provide a kind of memorial alloy ligatures the interactive locking bracket of asymmetric double-vane, it is fully expanded
Memorial alloy self-ligating bracket for orthodontic treatment field range of application, with workable, controllable correction silk and self-locking
