Technical Field

[0001] The invention relates to the technical field of orthodontic front traction equipment, and in particular to an implant support structure dedicated to orthodontic front traction. Background Art

[0002] During orthodontic treatment, any force applied to a tooth to move it will inevitably produce a force of the same magnitude and in the opposite direction. The reaction force caused by the tooth that supports this movement and correction is called "anchorage". Micro-implants are often used clinically to increase the anchorage of teeth.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The embodiment of the invention discloses an implant support structure specially used for anterior traction of oral orthodontics.

[0036] The present invention provides Figure 1-8 The shown embodiment of a special implant support structure for anterior traction of oral orthodontics includes a threaded support nail 6, a connecting wire 2 and a traction member 1 fixed at both ends of the connecting wire 2, wherein four connecting wires 2 are slidably connected with a moving block 3, and the four moving blocks 3 are equally divided into two groups, and a fixing component for fixing the moving block 3 and the connecting wire 2 is arranged in the moving block 3, and a first traction wire 4 is commonly fixed on every two corresponding moving blocks 3, and a primary adjustment block 5 is arranged between the two moving blocks 3 arranged in the same group, and the first traction wire 4 passes through the primary adjustment block 5 and slides in the primary adjustment block 5, and a primary adjustment mechanism for adjusting the tension of the first traction wire 4 is arranged in the primary adjustment block 5, and a secondary adjustment mechanism for adjusting the tension of the first traction wire 4 is arranged between the threaded support nail 6 and the primary adjustment block 5.

[0037] The tension of the first traction wire 4 is adjusted by adjusting the distance between the two correspondingly arranged moving blocks 3, such as Figure 1 , Figure 3 and Figure 5 As shown, the fixing assembly includes a first slide groove 31 opened in the moving block 3 for the connecting steel wire 2 to pass through, and a first circular hole 32 is also opened on one side of the moving block 3, a first bolt 33 is connected to the inner thread of the moving block 3, and both ends of the first bolt 33 are respectively located in the first slide groove 31 and the first circular hole 32, and the end of the first bolt 33 located in the first slide groove 31 can be tightly pressed against the connecting steel wire 2.

[0038] First, rotate the first bolt 33 so that the first bolt 33 moves into the first circular hole 32 and the first bolt 33 no longer squeezes the connecting wire 2, and the movable block 3 can be moved. When the position of the movable block 3 is adjusted, the first bolt 33 is rotated in the opposite direction so that the first bolt 33 contacts the connecting wire 2, that is, the movable block 3 and the connecting wire 2 are fixed. By adjusting the distance between the two movable blocks 3, the tension of the first traction wire 4 between the two movable blocks 3 can be adjusted.

[0039] Among them, a movable groove 51 and a rectangular groove 52 are opened in the first-level adjustment block 5, and the movable groove 51 and the rectangular groove 52 are connected, a rectangular block 55 is slidably connected in the rectangular groove 52, and a second sliding groove 56 for the first traction wire 4 to slide is opened in the rectangular block 55, and the first-level adjustment mechanism includes a second circular hole 53 opened on one side of the first-level adjustment block 5, a second bolt 54 is threadedly connected in the first-level adjustment block 5, and both ends of the second bolt 54 are respectively located in the second circular hole 53 and the movable groove 51, and the end of the second bolt 54 located in the movable groove 51 and one end of the rectangular block 55 are rotatably connected through an embedded bearing.

[0040] During operation, when the second bolt 54 is rotated, the second bolt 54 drives the rectangular block 55 to move in the rectangular groove 52. When the rectangular block 55 moves into the rectangular groove 52, the tension of the first traction steel wire 4 will increase, and the tension of the connecting steel wire 2 will increase. When the rectangular block 55 moves toward the side close to the second circular hole 53, the tension of the first traction steel wire 4 will decrease, and the tension of the connecting steel wire 2 will decrease.

[0041] In addition, a secondary adjustment block 10 is arranged between the threaded support nail 6 and the primary adjustment block 5, and a second traction steel wire 8 is fixed to one side of the primary adjustment block 5, and one end of the second traction steel wire 8 away from the primary adjustment block 5 is fixed to one side of the secondary adjustment block 10, and a third traction steel wire 9 is fixed to the other side of the secondary adjustment block 10, a retaining ring 7 is fixed to the outer side of the threaded support nail 6, and there is a gap between the retaining ring 7 and the nail cap of the threaded support nail 6 for the third traction steel wire 9 to be wound, and a receiving groove 12, a first slot 13, and a second slot 16 are provided in the secondary adjustment block 10, and the third traction steel wire 9 is slidably fitted in the receiving groove 12, the receiving groove 12 and the first slot 13 are connected, and the first slot 13 and the second slot 16 are connected.

[0042] It should be noted that when in use, the traction piece 1 is glued to the patient's teeth, and then each traction piece 1 is connected through the connecting steel wire 2 to achieve the traction effect. The medical staff then installs the threaded support nail 6 into the patient's alveolar bone, and the threaded support nail 6 cannot move. After that, the tension of the connecting steel wire 2 is adjusted through the moving block 3, the first-level adjustment block 5, and the second-level adjustment block 10.

[0043] Specifically, the secondary adjustment mechanism includes a rotating shaft 15 rotatably engaged in the first slot 13, and a worm gear 14 for contacting the third traction wire 9 is fixed to the outer side of the rotating shaft 15, and a driving unit for driving the worm gear 14 to rotate is provided in the second slot 16, and the worm gear 14 can drive the third traction wire 9 to move when it rotates, and the driving unit includes a worm 11 provided in the second slot 16, and one end of the worm 11 is rotatably connected to the inner wall of the second slot 16 through an embedded bearing, and the other end of the worm 11 passes through the secondary adjustment block 10 and is rotatably connected to the secondary adjustment block 10 and extends to the outside of the secondary adjustment block 10.

[0044] During operation, by rotating the worm 11, the worm 11 drives the worm wheel 14 to rotate. When the worm wheel 14 rotates, it will drive the third traction wire 9 to move. When the third traction wire 9 moves into the storage groove 12, the second traction wire 8 will drive the first-level adjustment block 5 to move closer to the second-level adjustment block 10. The tension of the first traction wire 4 will increase, and the tension of the connecting wire 2 will increase. Conversely, when the third traction wire 9 moves from the storage groove 12 to the outside, the tension of the first traction wire 4 will decrease, and the tension of the connecting wire 2 will decrease.
