Description
Technical field
The utility model belongs to the technical field of bracket, and in particular to a kind of multidirectional control double fluted lingual bracket.
Background technology
Bracket is the important component of tooth fixed orthodontics, is directly adhered to dental surface with bonding agent, arch wire passes through
Bracket and various types of Orthodontic forces are imposed to tooth.Bracket is made of stainless steel, bioceramic or compound resin, its main function
It is fixed arch wire, so that arch wire preferably plays a role, transmits Orthodontic force, the movement of tooth three-dimensional is controlled with this, is reached
The purpose of orthodontic therapy.
The groove that arch wire is fixed on conventional brackets body generally has one, and current existing double groove brackets are also only limitted to cheek side
Bracket, not only groove is parallel double grooves, and groove body shape is consistent.With pursuit of the people to therapeutic process Sino-U.S., tongue
Side bracket is rescued technology and is quickly grown, but traditional lingual bracket is single groove, to groove easy to tooth words to
The control in direction, but control near and far direction poor, tongue to groove vertically to and near and far direction controlling it is preferable, but words at the same time
It is weaker to direct torque power.In clinical tongue side treatment, no matter which kind of lingual bracket selected, for Patients labial teeth words
To direct torque it is inadequate.
The content of the invention
The utility model in order to solve existing bracket for Patients labial teeth words to direct torque it is inadequate
A kind of problem, there is provided multidirectional control double fluted lingual bracket.
The utility model adopts the following technical scheme realizes：
A kind of multidirectional control double fluted lingual bracket, including supporter groove and substrate, it is characterised in that the tongue of supporter groove to and
Side is respectively equipped with groove, and the groove main body section of side is square, and groove bottom is semicircle, tongue to groove section be trapezoidal
And it is configured with the identical trapezoidal arch wire of shape.
The groove main body section of side is square, and groove bottom is semicircle, semicircular a diameter of 0.018 inch, square
Partial height is 0.020-0.025 inches.
Tongue to groove section to be trapezoidal, trapezium base width is 0.018 inch, and trapezoidal height is 0.028 inch, trapezoidal
Bevel edge and the angle of short transverse are 5 ~ 10 °.
Side outside supporter groove opposed teeth is fitted with the cover board of surface polishing, cover board by supporter groove tongue to and
The groove covering of side, cover board are articulated and connected with supporter groove close to the side of gum side, and the folding direction of cover board is from side to gum side.
Substrate has some continuous semi-cylindrical hills with teeth contact face.
The utility model has the advantages that：
1st, words can be carried out at the same time to gradient and middle-distant direction Slope angle adjustment, tooth three-dimensional control is better achieved
Effect.
This bracket is designed using special-shaped double fluted, and is designed to groove for 0.018 inch of semicircular base of diameter, groove master
Body section is square, and the height of projected square part is 0.020-0.025 inches.
（1）In treatment starting stage, the conventional nitinol for using circular cross-section, arch wire selected as in clinical practice
0.012nd, 0.014,0.016,0.018 model, the semi-circular design of groove bottom, makes arch wire and groove bottom be point contact, tooth
Relative friction forces in movement between arch wire and groove substantially reduce, this is beneficial to the quick of tooth and comes into line.With arch wire and groove
Ditch contact area increases, and tooth gradually comes into line, while can also insert the arch wire of square-section to groove, and arch wire material may be selected
NiTi or stainless steel square arch wire, 0.014 × 0.022,0.016 × 0.022, after cover board covers, square arch wire will be to tooth
Tooth further comes into line.
（2）Tongue is designed to groove for trapezoidal cross-section, when needing to carry out direct torque to tooth, can select supporting ladder
Shape arch wire, when the closing gap stage carries out labial teeth direct torque in extraction cases, since trapezoidal arch wire is than traditional rectangular arch wire
More roomy base, the active force arm of force is longer, therefore torque indicator is up to more perfect.
（3）In rescuing can according to the needs for the treatment of plan, can in to and tongue insert corresponding arch wire at the same time to groove, this
Sample can be realized preferably to including on tooth three-dimensional direction vertically to, middle-distant direction and words to the control of torque.
2nd, the setting of cover board greatly improves the comfort level of patient.
3rd, the substrate of semi-cylindrical hill, which is set, makes substrate and denture adhesive degree more preferable.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model,
In figure：1- cover boards, 2- supporter grooves, 3- substrates, 4- are to groove, and 5- tongues are to groove.
Embodiment
Specific embodiment of the present utility model is described further with reference to attached drawing.
A kind of multidirectional control double fluted lingual bracket, including supporter groove and substrate, the tongue of supporter groove are respectively equipped with to side
Groove, the groove main body section of side are square, and groove bottom is semicircle, tongue to groove section be trapezoidal and supporting tangible
The identical trapezoidal arch wire of shape.
The groove main body section of side is square, and groove bottom is semicircle, semicircular a diameter of 0.018 inch, square
Partial height is 0.020-0.025 inches.
Tongue to groove section to be trapezoidal, trapezium base width is 0.018 inch, and trapezoidal height is 0.028 inch, trapezoidal
Bevel edge and the angle of short transverse are 5 ~ 10 °.
Side outside supporter groove opposed teeth is fitted with the cover board of surface polishing, cover board by supporter groove tongue to and
The groove covering of side, cover board are articulated and connected with supporter groove close to the side of gum side, and the folding direction of cover board is from side to gum side.
Substrate has some continuous semi-cylindrical hills with teeth contact face.
Clinically in use, during early period comes into line, tongue to and the groove of side in all practical round wire, the later stage
Arrange it is abnormal during, can be according to treatment, tongue is into the groove with side, circular, square, trapezoidal arch wire independent assortment makes
With.
The specification of round wire from 0.012-0.018 inches, come into line during when, as tooth gradually comes into line, bow used
Silk diameter is also more and more thicker.In the groove of side, round wire contact with groove bottom is from initial point contact to contact area
Gradually increase, is also achieved that the gradual increase for coming into line strength, completes adjustment of the words to gradient.
When later stage comes into line, in general square grooves ditch, trapezoidal arch wire is placed.Tongue generally uses square arch wire into groove, square
Contact of the arch wire with groove is four point contacts, so good to groove controling power, will not skid, can maintain early period well
Effect is come into line, aids in the action effect of the trapezoidal arch wire in square groove ditches.Complete the tune of middle-distant direction gradient and words to torque
It is whole.
