Then the staff puts the molding column into the mold cavity and installs the molding column on the implant, so that a cavity is formed between the molding column and the inner wall of the mold cavity. Finally, the staff injects fluid resin into the mold cavity, and then photocures the injected fluid resin to obtain the required personalized healing abutment.

[0007] The utility model is further configured as follows: the slats are detachably connected to the top of the formed body. Specifically, the slats are slidably connected to the top of the formed body through a sliding structure.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a personalized healing abutment rapid prototyping device includes a molding body 1 and a slat 2 slidably connected to the top of the molding body 1, the slat 2 is in a plurality of replaceable numbers, a card slot 8 is provided on the slat 2, a plurality of connecting blocks 7 formed by photocuring of a fluid resin are embedded in and bonded to the card slot 8, a plurality of connecting blocks 7 are respectively provided with mold cavities 10 of different structures, a plurality of implants 9 are detachably connected to the molding body 1, a molding column 13 is detachably connected to the implant 9, and a mold cavity 11 is formed between the molding column 13 and the inner wall of the mold cavity 10.

[0021] When actually using the personalized healing abutment rapid prototyping device, the staff first selects a mold cavity 10 with the shape of the tooth root required by the patient, and then selects a slat 2 with the mold cavity 10, and slides the slat 2 to connect it to the top of the molding body 1. At the same time, the mold cavity 10 is aligned with the required implant 9. Then, the staff puts the molding column 13 into the mold cavity 10 and installs the molding column 13 on the implant 9, so that a cavity 11 is formed between the molding column 13 and the inner wall of the mold cavity 10. Finally, the staff injects fluid resin into the mold cavity 11, and then photocures the injected fluid resin to obtain the required personalized healing abutment.

[0022] In addition, several slats 2 are provided and are replaceable, and several cavities 10 are opened on several slats 2, and the cavity 10 is formed by root molds of different structures. When the staff puts the molding column 13 into the cavity 10 to form the cavity 11, the staff can inject fluid resin into multiple cavities 11 with different structures at the same time, and then use light to cure the multiple cavities 11 filled with fluid resin at the same time, so as to obtain multiple healing abutments at one time. Therefore, in the actual use of the healing abutment rapid prototyping device, the present application greatly reduces the technical requirements for the production of personalized healing abutments, and the shorter time required for light curing can save a lot of time, thereby improving production efficiency and greatly reducing production costs.

[0023] In addition, since the connection block 7 is formed by photocuring of a fluid resin, a transparent fluid resin can be used to mold the connection block 7. The transparent fluid resin allows for faster photocuring and is easier for staff to observe.

[0024] Furthermore, the forming column 13 can be repeatedly used by sterilization.

[0025] like Figure 3 As shown, the slat 2 is detachably connected to the top of the molded body 1. Specifically, the slat 2 is slidably connected to the top of the molded body 1 through a sliding structure. The sliding structure includes sliders 5 respectively arranged on both sides of the molded body 1, and slide rails 6 for the sliders 5 to slide are respectively arranged on both sides of the slat 2. A protrusion 3 for limiting the position of the slat 2 is arranged at one end of the molded body 1, and a groove 4 for the protrusion 3 to be inserted is opened on the slat 2.

[0026] When the slat 2 is to be fixed on the molded body 1, the staff can first align the two sliders 5 at one end of the molded body 1 with the two slide rails 6 at one end of the slat 2 and snap them in, and then push the slat 2 until the protrusion 3 is snapped into the groove 4, and the installation of the slat 2 and the molded body 1 is completed, which is easy to operate.

[0027] When the staff wants to remove the slat 2, they only need to slide the slider 5 in a direction away from the groove 4 until the slider 5 is separated from the slide rail 6, and the slat 2 can be removed. The operation process is simple and quick.

[0028] like Figure 4 As shown, a plate groove 17 is provided on the top of the molded body 1 , a plurality of threaded holes 15 are provided in the plate groove 17 , and the implant 9 is threadedly connected to the inside of the threaded holes 15 .

[0029] like Figure 4 As shown, the implant 9 is detachably connected with a forming column 13, the forming column 13 is provided with a mounting block 19, and the implant 9 is provided with a mounting hole 18 for the mounting block 19 to be inserted. In this embodiment, the cross-section of the mounting block 19 and the mounting hole 18 can be one or a combination of a circle, a triangle, a quadrilateral, a pentagon or a hexagon.

[0030] When the mold cavity 10 is aligned with the implant 9, the staff can complete the installation of the molding column 13 by inserting the mounting block 19 into the mounting hole 18, and the mounting hole 18 limits the mounting block 19, so that the molding column 13 is not easy to shake, thereby making the shape of the cavity 11 more stable.

[0031] like Figure 4 As shown, a through hole 14 is formed inside the forming column 13 , a central bolt 20 is arranged inside the through hole 14 , and a threaded hole 16 for connecting the central bolt 20 is formed inside the implant 9 .

[0032] After the molding column 13 is fixed on the implant 9, the staff first puts the center bolt 20 into the through hole 14 so that the center bolt 20 is connected to the threaded hole 16, and then rotates the center bolt 20 downward so that the nut 12 of the center bolt 20 abuts against the molding column 13, thereby making the connection between the molding column 13 and the implant 9 more stable, thereby making the molding column 13 more stably fixed on the molding body 1.

[0033] Finally, the staff injects the fluid resin into the mold cavity 11, and then uses light to cure the fluid resin to complete the molding of the personalized healing abutment. The height of the healing abutment can also be adjusted according to the height of the patient's teeth to make the healing abutment fit the teeth better.

[0034] Working principle:

[0035] When actually using the personalized healing abutment rapid prototyping device, the staff first selects a mold cavity 10 with the shape of the tooth root required by the patient, and then selects a slat 2 with the mold cavity 10. Then, the staff aligns the two sliders 5 at one end of the molding body 1 with the two slide rails 6 at one end of the slat 2 and snaps them in, and then pushes the slat 2 until the protrusion 3 is snapped into the groove 4. When the slat 2 is installed on the molding body 1 and the mold cavity 10 is aligned with the implant 9, the staff snaps the mounting block 19 into the mounting hole 18 to complete the installation of the molding column 13. Then, the staff puts the center bolt 20 into the through hole 14 so that the center bolt 20 is connected to the threaded hole 16, and then rotates the center bolt 20 downward so that the nut 12 of the center bolt 20 abuts against the molding column 13, and at the same time makes the connection between the molding column 13 and the implant 9 more firmly, thereby making the molding column 13 more stably fixed on the molding body 1.

[0036] Finally, the staff injects the fluid resin into the cavity 11 and then cures the fluid resin with light to complete the molding of the personalized healing abutment.
