Detailed Description

The invention is described in further detail below with reference to the figures and the detailed description.

The manufacturing method of the orthodontic accessory protective sleeve comprises the following steps:

1) making a template

Set up multirow through-hole I2 that is parallel to each other on template 1, set up multirow and be parallel to each other and be used for placing the recess 3 of anchorage nail on template 1, through-hole I2 and recess 3 dislocation set. In this embodiment, six rows of through holes i 2 are formed in the template 1, and two rows of grooves 3 are formed in the template 1, as shown in fig. 1 to 3, the through holes i 2 and the grooves 3 in each row formed in the template 1 are parallel to each other, and a row of grooves 3 is formed every two rows of through holes i 2. The bottom of template 1 sets up at least three support column 19 that is used for supporting template 1, and in this embodiment, set up support column 19 respectively near four angles in the bottom of template 1, also can set up support column 19 in the other positions of template 1 bottom, and the quantity of setting can be at three or more, and when template 1 was placed on otter board 14 of oral cavity holder film pressing machine 7, template 1 supported the top at otter board 14 through support column 19 for there is the space between template 1 and the otter board 14, can not influence the evacuation like this.

Through holes of the bracket and the anchorage nail can also be respectively designed; or the designed template is scanned and then made into a digital template.

2) A row of brackets 4 are arranged between every two adjacent rows of through holes I2, and each row of brackets 4 is fixed on the template 1 through an arch wire 5; within the recess 3 is placed an anchorage pin 6, the head of the anchorage pin 6 protruding out of the upper surface of the formwork 1, as shown in fig. 4.

In the embodiment, the arch wire 5 passes through the horizontal groove on the brackets 4 on the corresponding row, the arch wire 5 is tied on the template 1, and each row of brackets 4 is pressed on the upper surface of the template 1 by the arch wire 5 passing through the horizontal groove. The arch wire 5 is a square arch wire (the thickest square arch wire in the orthodontic correction process is selected optimally), and the square arch wire is favorable for stably pressing the bracket 4 on the template 1. The arch wire 5 is positioned in the middle of the template 1 and the positions of the two sides of the template are fixed on the template 1 through the ligature wires 18 (a plurality of ligature wires can be arranged at other positions to fix the arch wire 5), the wires 18 are pressed on the corresponding arch wire 5, and the two ends of the wires 18 penetrate through the through holes I2 of the two sides of the arch wire 5 and are fixed between the through holes I2 of the two sides.

3) Using the mouth retainer film press 7, the mouth retainer film press 7 is a prior art product, as shown in fig. 5; the upper cover 8 of the oral cavity retainer film pressing machine 7 is turned off, the diaphragm 9 is placed between the upper sleeve frames 10, and the ball head pull rod 11 is pulled down to clamp the diaphragm; resetting the upper cover 8, and pressing down the lifting wrench 12 to lift the sleeve frame 10 to the working height; then, the template 1 provided with the bracket 4 and the anchorage nail 6 is placed on the screen plate 14 in the lower frame 13, as shown in fig. 6, a certain distance is kept between the template 1 and the screen plate 14 through a support column 19 at the bottom, and the air on the template 1 is completely pumped out from the lower part during vacuum pumping; turning on a heating switch 15, heating the membrane 9, turning off the heating switch 15 when the membrane 9 is heated and is lower than the plane of the lower frame 13, putting down the sleeve frame 10, turning on a vacuum motor, gradually sleeving the heated membrane 9 on the bracket 4 and the anchorage pin 6 when the membrane 9 is vacuumized downwards, and forming a bracket protective sleeve 16 and an anchorage pin protective sleeve 17 on the membrane 9; after the bracket protective sheath 16 and the anchorage pin protective sheath 17 are formed, the vacuum motor is turned off.

4) The template 1 is taken out, and the formed membrane 9 is taken off from the template 1.

5) The bracket protecting sleeve 16 and the anchorage pin protecting sleeve 17 are cut off from the formed membrane 9 to form the bracket protecting sleeve 16 and the anchorage pin protecting sleeve 17 which are independent from each other, the structure of the bracket protecting sleeve 16 is shown in figure 7, the two corresponding walls of the bracket protecting sleeve 16 are provided with clamping grooves 20, and the structure of the anchorage pin protecting sleeve 17 is shown in figure 8. The lower edge of the bracket protective sleeve 16 and the anchorage pin protective sleeve 17 is inwardly provided with an annular elastic sleeve 21, the annular elastic sleeve 21 has certain elasticity, which is not only beneficial to sleeving the bracket protective sleeve 16 and the anchorage pin protective sleeve 17 on the corresponding bracket 4 and the anchorage pin 6, but also beneficial to fixing the bracket protective sleeve 16 and the anchorage pin protective sleeve 17 on the corresponding bracket 4 and the anchorage pin 6. The anchorage pin protective sleeve 17 can be circular or triangular, and the shape of the anchorage pin protective sleeve 17 is determined according to the specific shape of the anchorage pin 6.

When the base of the bracket 4 is stuck on the surface of a tooth, the bracket protective sleeve 16 is sleeved on the bracket 4, the clamping grooves 20 at two sides of the bracket protective sleeve 16 are clamped on the corresponding square arch wire, the bracket 4 is prevented from directly contacting with the oral mucosa, but the bracket protective sleeve 16 with smooth surface contacts with the oral mucosa, and the oral mucosa is effectively protected; the bracket protective sheath 16 and the bracket 4 form a good tight fit, the bracket protective sheath 16 is not easy to fall off on the bracket 4, and even if the bracket protective sheath 16 falls off, the bracket protective sheath 16 can be repeatedly used. When the anchorage nail 6 is implanted at the membrane-gingival junction or the occlusal side of the membrane-gingival junction, the anchorage nail protective sleeve 17 is sleeved at the head of the anchorage nail 6, so that the anchorage nail 6 is prevented from directly contacting with the oral mucosa, and the oral mucosa is effectively protected by the anchorage nail protective sleeve 17 with smooth surface; simultaneously, anchorage nail protective sheath 17 forms good tight fit with anchorage nail 6, and anchorage nail protective sheath 17 is difficult for droing on anchorage nail 6, even anchorage nail protective sheath 17 droing, anchorage nail protective sheath 17 also can used repeatedly. Moreover, in the manufacturing process, the thickest main arch wire is selected as the arch wire 5, and the clamping groove 20 with larger size is formed on the bracket protective sleeve 16 after the manufacturing is finished, so that in the orthodontic process, the clamping groove 20 on the bracket protective sleeve 16 is clamped on the orthodontic main arch wire without positive pressure on the orthodontic main arch wire, and the application of the bracket protective sleeve 16 can not increase the friction force of the appliance system.

According to the invention, by arranging the template 1 capable of being provided with the plurality of brackets 4 and the plurality of anchorage pins 6 and combining the template 1 with the oral cavity retainer film pressing machine 7, a plurality of bracket protective sleeves 16 completely matched with the shapes of the brackets 4 and a plurality of anchorage pin protective sleeves 17 completely matched with the shapes of the heads of the anchorage pins 6 can be formed at one time, and the manufacturing method is rapid and efficient.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
