Description
Technical Field
The invention relates to the technical field of tooth orthodontic brackets, in particular to a special-shaped arch wire locking device.
Background
The bracket and the arch wire are important parts in the correction technology, the arch wire applies various correction forces to teeth through the bracket, and the bracket has the main function of fixing the arch wire through the linear arch wire groove of the bracket, so that the arch wire transmits correction force, namely, the dislocation teeth are corrected by traction of the elastic force of the arch wire, thereby controlling the three-dimensional movement of the teeth and achieving the purpose of correcting the teeth. So that whether the arch wire is firmly matched with the bracket or not can accurately express the correction force is one of factors influencing the orthodontic effect. The staggered teeth are arranged irregularly, and the archwire is difficult to penetrate into the bracket-shaped archwire slot on each tooth surface. For this purpose, thinner or thinner archwires are required, and larger gauge archwires are replaced as the orthodontic progresses. Currently, archwires are circular and rectangular in cross-section, and if the rectangular or circular archwire is sized smaller than the straight archwire slot to facilitate penetration into the archwire slot in order to facilitate penetration into the straight archwire slot, the archwire will move within the straight archwire slot and thus affect the corrective effect due to the smaller size of the archwire than the straight archwire slot.
To this end, in order to solve the problem of archwires or archwires moving within the archwire slot, two solutions have emerged in the prior art:
(1) Prior art 1: a special-shaped arch wire is designed, and an arch wire groove is arranged to be a special-shaped main groove matched with the special-shaped arch wire, and the special-shaped arch wire is tightly matched with the special-shaped main groove to achieve the effect of clamping the arch wire, so that the arch wire cannot move randomly in the main groove, the expression of force by the arch wire is influenced, and the expression of torque is influenced (as in U.S. patent with publication number of US5174753A 1).
(2) Prior art 2: the archwire in the archwire slot is abutted by the locking element, and the locking element used at present mainly aims to limit the archwire with a rectangular or circular cross section in a small amount (the locking element can only abut against one surface of the rectangular archwire in the main slot, and the locking element can only abut against one line of the circular archwire in the main slot), so that the archwire cannot move in the main slot to a large extent (as in the Chinese patent publication No. CN105852994A filed by the applicant).
However, the two prior arts have the following disadvantages:
prior art 1: the use of dysmorphism arch wire needs the design and use with dysmorphism arch wire matched with dysmorphism main slot, dysmorphism main slot's size is close with the size of dysmorphism arch wire, and dysmorphism arch wire also hardly penetrates in the dysmorphism main slot, has increased the degree of difficulty of use.
Prior art 2: the locking element can not fully prop against the arch wire, the locking element can only prop against one surface of the rectangular arch wire in the main groove, the locking element can only prop against one line of the circular arch wire in the main groove, a large amount of clearance exists in the main groove, and when the arch wire shakes, the arch wire can easily move towards other directions because the arch wire only has one surface or one line which contacts the main groove, so that the arch wire can not well express acting force, and the torque expression is influenced.

A special-shaped arch wire locking device is characterized in that: comprises a special-shaped arch wire, a bracket and a locking element; the bracket comprises a bracket main body, wherein a main groove is formed in the upper surface of the bracket main body, and a locking hole is formed in the side surface of the bracket main body; the special-shaped arch wire comprises an inclined plane or a plane with a blind hole; the special-shaped arch wire is placed in the main groove, one end of the locking element penetrates through the locking hole and extends into the main groove to be in abutting contact with the inclined plane of the special-shaped arch wire or the blind hole on the surface with the blind hole.
2. A contoured archwire locking device as set forth in claim 1, wherein: the special-shaped arch wire at least comprises a first plane and a second plane which are adjacent to each other along the length direction of the special-shaped arch wire, a first adjacent angle is arranged between the first plane and the second plane, and the surface opposite to the first adjacent angle is the inclined surface or the surface with the blind hole; the main groove at least comprises a third plane and a fourth plane which are two adjacent planes along the length direction of the main groove, and a second adjacent angle is formed between the third plane and the fourth plane; the angle of the first adjacent angle is equal to the angle of the second adjacent angle, and the first adjacent angle coincides with the second adjacent angle when the special-shaped archwire is abutted in the main groove by the locking element.
3. A shaped archwire locking device as claimed in claim 1 or 2, wherein: the cross section of the special-shaped arch wire is triangular or trapezoidal.
4. A shaped archwire locking device as claimed in claim 1 or 2, wherein: the cross section of the special-shaped arch wire is triangular with a blind hole or trapezoid with a blind hole or rectangle with a blind hole.
5. A shaped archwire locking device as claimed in claim 1 or 2, wherein: the inclined plane is a smooth curved surface.
6. A contoured archwire locking device as set forth in claim 5, wherein: the smooth curved surface is an outwards convex arc curved surface or an inwards concave arc curved surface.
7. A contoured archwire locking device as in claim 2, wherein: the first adjacent angle and the second adjacent angle are right angles.
8. A contoured archwire locking device as set forth in claim 1, wherein: the locking element is a bolt, the bolt comprises a nut and a screw rod, and the top surface of the screw rod is a plane, an inclined plane or a spherical surface; the locking element is connected with the locking hole through threads.
9. A contoured archwire locking device as set forth in claim 8, wherein: the diameter of the cross section of the screw is smaller than the width of the cross section of the blind hole.
10. A method of using a shaped archwire locking device as set forth in claim 2, comprising the steps of:
step one, determining the position of a locking hole of a bracket on the side surface of a main groove;
step two, the inclined plane of the special-shaped arch wire or the side surface of the main groove with the blind hole facing to the opened locking hole is penetrated into the main groove;
step three: inserting the locking element into the locking hole, and rotating the locking element until touching the inclined plane of the special-shaped arch wire or the surface with the blind hole;
step four, rotating the locking element until the first adjacent angle coincides with the second adjacent angle;
step five: the rotation of the locking element is stopped and the special-shaped arch wire is abutted against the main groove.
