Description

Technical Field

[0001] The present invention belongs to the technical field of dental implantation, and in particular relates to a personalized bridge frame and screws, a manufacturing device and a manufacturing method. Background Art

[0002] When multiple teeth or the entire mouth are implanted, an implant bridge is needed to support the restoration. Multiple composite abutments are installed on the upper and lower jaws, and then the bridge is fixed to the composite abutments with screws to complete the installation of the bridge. In order to make the patient comfortable after the bridge is installed and to ensure normal chewing and biting after installation, the requirements for bridge processing are extremely high. The existing bridges and screws are manufactured through oral dental CAD / CAM digital manufacturing processes. The manufacturing process is to obtain a three-dimensional image of the patient's teeth and oral cavity through a scanner, import the three-dimensional image into the CAD design software, create a 3D model of the repaired product, and then prepare it through 3D printing or milling.

[0003] When existing manufacturing equipment is used to make personalized bridge frames and screws, it is necessary to obtain a 3D model of the product before the production can proceed, which makes the product preparation cycle longer, thereby increasing the time patients have to wait for implantation; the prepared personalized abutment and screws need to be installed on a composite abutment, and when the composite abutment is implanted on the frontal bone, it takes a long time for it to fuse firmly, which makes the patient's dental implant cycle longer and increases the time patients endure pain; at the same time, the existing dental implants are extremely expensive, which limits the customer base and is not convenient for product promotion.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a personalized bridge frame and screws, a manufacturing device and a manufacturing method, which can solve the problems of long product preparation cycle and long tooth implantation cycle.

[0006] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0007] Personalized bridge and screws, including:

[0008] The bridge and screws include a bridge body. In order to meet the needs of implanting multiple teeth or all teeth of a patient, a bridge body is provided so that the restoration can be supported and fixed by the bridge body. A plurality of mounting platforms are installed on the bridge body in an integrated manner. The mounting platforms are used to install a single implanted tooth, so that a single tooth can be detachably mounted on the mounting platforms, thereby facilitating the maintenance and replacement of individual teeth in the later stage. A plurality of fixing platforms are installed on the side wall of the bridge body in an integrated manner. Since the bridge body needs to be installed in the oral cavity during use and the stability after installation needs to be ensured, a fixing platform is provided so that the bridge body can be installed and fixed by a connecting piece. The fixing platform is internally threaded with a screw body, and the fixing platform can be fixed to the connecting piece by the screw body, thereby ensuring the firmness of the bridge body after installation.

[0009] The composite abutment, in order to ensure that the bridge and screws can be stably installed in the patient's oral cavity, is implanted in the patient's frontal bone by implanting the composite abutment. Through the fusion between the composite abutment and the frontal bone, it can be ensured that the composite abutment and the frontal bone are firmly connected, so that the bridge and screws are installed on the composite abutment, so that the bridge and screws are firmly installed. It includes an abutment body, and the bottom of the abutment body is installed with an implant rod in an integrated manner. The implant rod is used to be implanted in the frontal bone and is fused with the frontal bone through the implant rod. A connector is installed on the abutment body in an integrated manner, and the connector is used to connect with the bridge and screws, so that the bridge and screws can be installed on the composite abutment. An external threaded body is provided on the side wall of the implant rod. In order to ensure that when the implant rod is installed in the frontal bone and the implant rod and the frontal bone are dissolved, the two can remain stable. By providing an external threaded body on the side wall of the implant rod, the implant rod can be stably installed in the frontal bone through the external threaded body, so that the implant rod and the frontal bone are firmly connected, so that before the frontal bone and the implant rod are completely dissolved, the composite base can be installed on the bridge and screws in advance, thereby greatly shortening the period of dental implantation. A plurality of first ventilation grooves are longitudinally provided on the external threaded body. In order to ensure the stability between the implant rod and the frontal bone, the first ventilation grooves are provided so that when the frontal bone and the implant rod are dissolved, the dissolved components will enter the first ventilation grooves, thereby increasing the stability between the frontal bone and the implant rod. At the same time, under the action of the first ventilation groove, when the implant rod is threadedly connected to the frontal bone, the air in the frontal bone mounting hole can be discharged through the first ventilation groove. Since the air in the frontal bone mounting hole will be squeezed during the installation of the implant rod, the installation of the composite base will be obstructed, and at the same time, it will cause a burden on the frontal bone and increase the risk of patient discomfort. Therefore, this problem can be well solved through the first ventilation groove.

[0010] A dental crown is a single tooth implanted with a tooth for chewing and biting, so it needs to be firmly installed. It includes a dental crown body, and a third threaded rod is installed at the bottom of the dental crown body in an integrated manner. The third threaded rod is connected to the connecting piece so that the third threaded rod can be firmly installed, thereby making the dental crown body firmly installed.

[0011] In one or more embodiments of the present invention, a plurality of the mounting platforms are provided with a first threaded hole, so that the teeth can be easily mounted on the mounting platform. A plurality of the fixing platforms are provided with a second threaded hole and an assembly groove, the assembly groove is arranged above the second threaded hole, the screw body is threadedly connected in the second threaded hole, the head of the screw body is sleeved in the assembly groove, and the end of the screw body away from the head is placed on the lower side of the fixing platform. The screw body is installed in the second threaded hole by threaded connection, so that the screw body is stable after installation, and when the screw body is threadedly connected in the second threaded hole, the head of the screw body will be placed in the assembly groove, so that the screw body is placed in the fixing platform, and the head of the screw body is fully matched in the assembly groove, avoiding saliva and the like from entering the assembly groove, reducing the occurrence of pollution sources, and being beneficial to oral health. At the same time, the lower end of the screw body is placed on the lower side of the fixing platform, so that it can be connected to the connecting piece through the lower end of the screw body, so that the screw body can be stably installed on the connecting piece, so that the fixing platform can be stably installed on the connecting piece, thereby making the fixing platform stably installed on the connecting piece.

[0012] In one or more embodiments of the present invention, the bridge body and the mounting platform both include a first blank body arranged inside and an anti-rejection layer arranged outside. The anti-rejection layer is arranged on the outer surface of the first blank body by cladding or 3D printing, so that the anti-rejection layer and the first blank body are firmly connected to meet the requirements of use.

[0013] In one or more embodiments of the present invention, the fixing platform and the anti-rejection layer are both made of pure titanium material, and the screw body and the first blank body are both made of stainless steel material. Since the fixing platform and the anti-rejection layer will come into contact with human tissue during use, the fixing platform and the anti-rejection layer are made of pure titanium material, so that no rejection will occur when in contact with the human body, thereby reducing the risk of infection when the bridge and the screw are installed in the patient's mouth. The screw body and the first blank body will not come into contact with human tissue, and the first blank body is a structure inside the bridge body. The screw body and the first blank body are made of stainless steel, which increases the strength of related components while reducing the cost of raw materials, thereby reducing the cost of dental implants. Before making a bridge and screws for the patient, the screw body and the first blank body can be prefabricated in advance. The first blank body can be classified and prefabricated according to patients of different age groups and the number of implanted teeth. During production, the first blank body that matches the patient is selected, and an anti-rejection layer is set on the surface of the first blank body so that a bridge and screws that highly match the patient can be produced by adjusting the thickness of the anti-rejection layer. Therefore, the production of the bridge and screws only requires setting an anti-rejection layer on the outer surface of the first blank body, and then completing the production of the fixing platform, thereby greatly shortening the production cycle of the bridge and screws.

[0014] In one or more embodiments of the present invention, a third threaded hole is provided in the connector, and one end of the screw body placed on the lower side of the fixing platform is threadedly connected to the third threaded hole, so that the connector is a connector connected to the screw body. By threading the lower end of the screw body into the third threaded hole, the screw body can be fixed to the connector, so that the composite base can be installed on the bridge and the screw. The first ventilation groove is provided from the upper end thread of the external thread body to the lower end thread in a through manner, so that when the implant rod is installed in the frontal bone, the air in the frontal bone installation hole can flow upward along the first ventilation groove and be discharged. A plurality of pyramid-shaped protrusions are fixedly connected to the inner side wall of the first ventilation groove, and the protrusions are arranged on the inner side wall of the first ventilation groove in an irregular manner. By arranging the protrusions on the inner side wall of the first ventilation groove in an irregular manner, the implant rod and the frontal bone can be more stable after being fused. At the same time, under the action of the protrusions, when the implant rod is initially threadedly connected to the frontal bone, the two can remain stable before fusion.

[0015] In one or more embodiments of the present invention, the base body and the implant rod both include a second blank body arranged inside and a fusion layer arranged outside, and the fusion layer is arranged on the outer surface of the second blank body by cladding or 3D printing, so that the second blank body and the fusion layer are firmly installed. The second blank body is made of stainless steel material, and the fusion layer is made of pure titanium material. The fusion layer is in contact with the frontal bone of the human body, so they need to have good biocompatibility with each other, so the fusion layer is made of pure titanium material. The second blank body is made of stainless steel material to ensure the strength of the composite base while reducing the cost. At the same time, the second blank body can be prefabricated in advance, and the fusion layer is set on the surface of the second blank body so that the shape of the composite base after production is consistent with the design, thereby greatly shortening the production cycle of the composite base.

[0016] In one or more embodiments of the present invention, the third threaded rod is threadedly connected to the first threaded hole, so that the crown body can be stably mounted on the mounting table through the cooperation of the third threaded rod and the first threaded hole. A second ventilation groove is provided on the external thread of the third threaded rod, and the second ventilation groove is provided in a penetrating manner from the second thread at the upper end of the external thread of the third threaded rod to the lower end of the external thread, so that when the third threaded rod is installed in the first threaded hole, the air in the first threaded hole is compressed by the third threaded rod and then discharged through the second ventilation groove. At the same time, the second ventilation groove is not provided on the first thread at the uppermost end of the external thread of the third threaded rod, so that when the third threaded rod is installed in the first threaded hole, the saliva on the outside is prevented from entering the first threaded hole under the action of the first thread at the uppermost end of the third threaded rod.

[0017] The manufacturing equipment of personalized bridge and screws includes:

[0018] A production system, wherein the production system adopts a CAD / CAM digital production process, wherein the CAD / CAM digital production process includes oral image acquisition, production of oral 3D images, and production of product 3D images;

[0019] The manufacturing device includes a milling machine and a laser cladding 3D printer. The milling machine is used to manufacture the screw body, the first blank body and the second blank body. At the same time, the threaded holes on the screw body, the first blank body and the second blank body need to be manufactured. The laser cladding 3D printer is used to set the anti-rejection layer on the side wall of the first blank body by laser cladding, and then fix the fixing table to the outer side wall of the anti-rejection layer by 3D printing; and set the fusion layer on the side wall of the second blank body by 3D printing.

[0020] In one or more embodiments of the present invention, the oral image acquisition is performed by acquiring images of the patient's teeth and oral cavity through a scanner, the oral three-dimensional map is produced by obtaining a three-dimensional map of the patient's oral cavity based on the images acquired through the oral image acquisition, the product three-dimensional map is produced by creating a three-dimensional map of the product obtained by repairing the oral three-dimensional map, and the printing powder of the laser cladding 3D printer is powder of pure titanium material.

The production system produces a three-dimensional image of a personalized bridge frame and screw product, and adopts CAD / CAM digital production technology to obtain a three-dimensional image of the patient's oral cavity through image acquisition, and creates and repairs the three-dimensional image of the product based on the three-dimensional image of the patient's oral cavity; uses a scanner to collect images of the patient's teeth and oral cavity, and produces a three-dimensional image of the patient's oral cavity based on the collected images, and creates and repairs the three-dimensional image of the product that matches the patient's oral cavity based on the three-dimensional image of the patient's oral cavity.

[0023] S2. The manufacturing device manufactures personalized bridge and screw products, and the manufacturing of personalized bridge and screw products is completed by combining a milling machine and a laser cladding 3D printer. The screw body, the first blank body and the second blank body are manufactured by a milling machine, and then the first blank body and the second blank body matching the product to be manufactured are selected according to the three-dimensional diagram of the product. The laser cladding 3D printer clads the anti-rejection layer on the outer surface of the first blank body by laser cladding according to the three-dimensional diagram of the product, so that the bridge body composed of the first blank body and the anti-rejection layer is the same as the bridge body in the three-dimensional diagram of the product, and then multiple fixed platforms are manufactured on the side wall of the bridge body by 3D printing. The second threaded hole and assembly groove inside the fixed platform need to have a matching screw body, so as to complete the manufacturing of the bridge and screw; then the fusion layer is clad on the side wall of the second blank body by a laser cladding 3D printer, so as to complete the manufacturing of the composite base. At the same time, when manufacturing the second blank body, it should be noted that the third threaded hole should be set to match the screw body required by the fixed platform.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] The bridge frame and composite abutment provided by the present invention are composed of an inner blank body and an outer layer. The blank body can be prefabricated in advance, and the screws can also be prefabricated in advance, so that when making personalized bridge frames and screws, it is only necessary to make the outer layer on the side wall of the blank body by 3D printing or cladding according to the three-dimensional product image of the corresponding patient, thereby greatly shortening the production cycle of personalized abutments and bridge frames;

[0026] The present invention provides an external threaded body on the implant rod of the composite abutment, and the composite abutment is threadedly connected to the frontal bone through the external threaded body, so that the composite abutment and the frontal bone are firmly installed before they are fused with each other.

[0027] The present invention shortens the production cycle of personalized bridges and screws and the cycle of tooth implantation, thereby greatly shortening the cycle for patients to customize personalized bridges and screws and complete tooth implantation, thereby reducing the waiting time for patients to implant teeth and reducing the pain caused by tooth discomfort. At the same time, by changing the structure of the bridge and the composite abutment, the cost of tooth implantation is reduced, which is conducive to the promotion of the product.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, a personalized bridge and screw in one embodiment of the present invention comprises a bridge and screw 1, a composite base 2 and a crown 3.

[0041] like Figure 1 and Figure 2 As shown, the bridge and screw 1 include a bridge body 11. In order to meet the needs of implanting multiple teeth or all teeth of a patient, the bridge body 11 is provided so that the restoration can be supported and fixed by the bridge body 11. A plurality of mounting platforms 12 are installed on the bridge body 11 in an integrated manner. The mounting platforms 12 are used to install a single tooth during implantation, so that a single tooth can be detachably mounted on the mounting platforms 12, thereby facilitating the maintenance and replacement of individual teeth in the later stage. A plurality of fixing platforms 14 are installed on the side wall of the bridge body 11 in an integrated manner. Since the bridge body 11 needs to be installed in the oral cavity during use and the stability after installation needs to be ensured, a fixing platform 14 is provided so that the bridge body 11 can be installed and fixed by a connecting piece. The fixing platform 14 is internally threadedly connected to a screw body 17, and the fixing platform 14 can be fixed to the connecting piece by the screw body 17, thereby ensuring the firmness of the bridge body 11 after installation.

[0042] like Figure 2~Figure 4As shown, a plurality of mounting platforms 12 are provided with first threaded holes 13, so that the teeth can be easily mounted on the mounting platforms 12. A plurality of fixing platforms 14 are provided with second threaded holes 15 and assembly grooves 16, the assembly grooves 16 are arranged above the second threaded holes 15, the screw body 17 is threadedly connected in the second threaded holes 15, the head of the screw body 17 is sleeved in the assembly grooves 16, and the end of the screw body 17 away from the head is placed on the lower side of the fixing platform 14. The screw body 17 is installed in the second threaded hole 15 by threaded connection, so that the screw body 17 is stable after installation, and when the screw body 17 is threadedly connected in the second threaded hole 15, the head of the screw body 17 is placed in the assembly groove 16, so that the screw body 17 is placed in the fixing platform 14, and the head of the screw body 17 is fully matched in the assembly groove 16, so that saliva and the like are prevented from entering the assembly groove 16, reducing the occurrence of pollution sources, which is beneficial to oral health. At the same time, the lower end of the screw body 17 is placed on the lower side of the fixing platform 14 so that it can be connected to the connecting piece through the lower end of the screw body 17, so that the screw body 17 can be stably installed on the connecting piece, so that the fixing platform 14 can be stably installed on the connecting piece, thereby making the fixing platform 14 stably installed on the connecting piece.

[0043] like Figure 4 As shown, the bridge body 11 and the mounting platform 12 both include a first blank body 18 arranged inside and an anti-rejection layer 19 arranged outside. The anti-rejection layer 19 is arranged on the outer surface of the first blank body 18 by cladding or 3D printing, so that the anti-rejection layer 19 and the first blank body 18 are firmly connected to meet the requirements of use.

[0044] Preferably, the fixing platform 14 and the anti-rejection layer 19 are both made of pure titanium material, and the screw body 17 and the first blank body 18 are both made of stainless steel material. Since the fixing platform 14 and the anti-rejection layer 19 will come into contact with human tissue during use, the fixing platform 14 and the anti-rejection layer 19 are made of pure titanium material, so that no rejection will occur when in contact with the human body, thereby reducing the risk of infection when the bridge and the screw 1 are installed in the patient's mouth. The screw body 17 and the first blank body 18 will not come into contact with human tissue, and the first blank body 18 is a structure inside the bridge body 11. The screw body 17 and the first blank body 18 are made of stainless steel, which increases the strength of related components while reducing the cost of raw materials, thereby reducing the cost of dental implants.

[0045] Furthermore, before making the bridge and screw 1 for the patient, the screw body 17 and the first blank body 18 can be prefabricated in advance. The prefabrication of the first blank body 18 can be classified and prefabricated according to patients of different age groups and the number of implanted teeth. When the final product is made, the first blank body 18 that matches the patient is selected, and an anti-rejection layer 19 is set on the surface of the first blank body 18, so that the thickness of the anti-rejection layer 19 can be adjusted to make a bridge and screw 1 that matches the height of the patient. Therefore, the production of the bridge and screw 1 only needs to set the anti-rejection layer 19 on the outer surface of the first blank body 18, and then complete the production of the fixing table 14, thereby greatly shortening the production cycle of the bridge and screw 1.

[0046] like Figure 6~Figure 8 As shown, the composite abutment 2 is to ensure that the bridge and the screw 1 can be stably installed in the patient's oral cavity. By implanting the composite abutment 2 in the patient's frontal bone, and then fusing the composite abutment 2 with the frontal bone, it can be ensured that the composite abutment 2 and the frontal bone are firmly connected, so that the bridge and the screw 1 are installed on the composite abutment 2, so that the bridge and the screw 1 are firmly installed. The composite abutment 2 includes an abutment body 21, and the bottom of the abutment body 21 is installed with an implant rod 22 in an integrated manner. The implant rod 22 is used to be implanted in the frontal bone and is fused with the frontal bone through the implant rod 22. A connector 23 is installed on the abutment body 21 in an integrated manner. The connector 23 is used to connect with the bridge and the screw 1, so that the bridge and the screw 1 can be installed on the composite abutment 2. An external threaded body 24 is provided on the side wall of the implant rod 22. In order to ensure that when the implant rod 22 is installed in the frontal bone and the implant rod 22 and the frontal bone are dissolved in each other, the external threaded body 24 is provided on the side wall of the implant rod 22 so that the implant rod 22 can be stably installed in the frontal bone through the external threaded body 24, so that the implant rod 22 and the frontal bone are firmly connected, so that the composite base 2 can be installed on the bridge and the screw 1 in advance before the frontal bone and the implant rod 22 are completely dissolved in each other, thereby greatly shortening the tooth implantation cycle.

[0047] Furthermore, if Figure 6 and Figure 7As shown, a plurality of first ventilation grooves 25 are longitudinally provided on the external threaded body 24. In order to ensure the stability between the implant rod 22 and the frontal bone, the first ventilation grooves 25 are provided so that when the frontal bone and the implant rod 22 are fused, the fused components will enter the first ventilation grooves 25, thereby increasing the stability between the frontal bone and the implant rod 22. At the same time, under the action of the first ventilation grooves 25, when the implant rod 22 is threadedly connected to the frontal bone, the air in the frontal bone mounting hole can be discharged through the first ventilation grooves 25. Since the implant rod 22 will squeeze the air in the frontal bone mounting hole when it is installed, the installation of the composite base 2 will be obstructed, and at the same time, it will cause a burden on the frontal bone, increasing the risk of discomfort to the patient. Therefore, the first ventilation grooves 25 can well solve this problem.

[0048] like Figure 7 As shown, a third threaded hole 26 is provided in the connector 23, and one end of the screw body 17 placed on the lower side of the fixing platform 14 is threadedly connected to the third threaded hole 26, so the connector 23 is a connector connected to the screw body 17. By threading the lower end of the screw body 17 into the third threaded hole 26, the screw body 17 can be fixed to the connector 23, so that the composite base 2 can be installed on the bridge and the screw 1. The first ventilation groove 25 is provided from the upper end thread of the external threaded body 24 to the lower end thread in a penetrating manner, so that when the implant rod 22 is installed in the frontal bone, the air in the frontal bone installation hole can flow upward from the bottom of the implant rod 22 along the first ventilation groove 25 and be discharged. A plurality of pyramid-shaped protrusions are fixedly connected to the inner wall of the first ventilation groove 25, and the protrusions are arranged on the inner wall of the first ventilation groove 25 in an irregular manner. By arranging the protrusions on the inner wall of the first ventilation groove 25 in an irregular manner, the stability of the implant rod 22 and the frontal bone after they are fused can be better. At the same time, under the action of the protrusions, when the implant rod 22 is threadedly connected to the frontal bone, the stability between the implant rod 22 and the frontal bone when they are not fused is further improved, so that the bridge frame and the screw 1 can be installed in advance before the implant rod 22 and the frontal bone are not completely fused.

[0049] Preferably, when the composite base 2 is installed in the frontal bone, the orientation of the connector 23 after installation needs to be consistent with the design, so as to facilitate the connection between the screw body 17 and the connector 23. Therefore, when the implant rod 22 is threadedly connected to the frontal bone, when it is rotated to the last circle, it is sufficient to ensure that the position of the connector 23 is rotated to the designed direction, so as to avoid damage to the frontal bone by continuing to forcefully adjust the position of the connector 23 after the implant rod 22 is rotated into place. At the same time, in order to adjust the position of the connector 23, when the implant rod 22 is not rotated into place in the last circle, the stability of the composite base 2 can be ensured under the action of the first ventilation groove 25 and the protrusion on the inner wall of the first ventilation groove 25.

[0050] like Figure 8As shown, the base body 21 and the implant rod 22 both include a second blank body 27 disposed inside and a fusion layer 28 disposed outside. The fusion layer 28 is disposed on the outer surface of the second blank body 27 by cladding or 3D printing, so that the second blank body 27 and the fusion layer 28 are firmly installed. The second blank body 27 is made of stainless steel material, and the fusion layer 28 is made of pure titanium material. The fusion layer 28 is in contact with the frontal bone of the human body, so they need to have good biocompatibility with each other, so the fusion layer 28 is prepared by pure titanium material. The second blank body 27 is made of stainless steel material to ensure the strength of the composite base 2 while reducing the cost. At the same time, the second blank body 27 can be prefabricated in advance, and the fusion layer 28 is arranged on the surface of the second blank body 27 so that the shape of the composite base 2 after production is consistent with the design, thereby greatly shortening the production cycle of the composite base 2.

[0051] like Figure 1~Figure 5 As shown, the crown 3 is a single tooth after dental implantation, which is used for chewing and biting, so it needs to be firmly installed. The crown 3 includes a crown body 31, and a third threaded rod 32 is installed at the bottom of the crown body 31 in an integrated manner. The third threaded rod 32 is connected to the connecting piece so that the third threaded rod 32 can be firmly installed, thereby making the crown body 31 firmly installed.

[0052] like Figure 3~Figure 5 As shown, the third threaded rod 32 is threadedly connected to the first threaded hole 13, and the crown body 31 can be stably installed on the mounting platform 12 through the cooperation of the third threaded rod 32 and the first threaded hole 13. A second ventilation groove 33 is provided on the external thread of the third threaded rod 32, and the second ventilation groove 33 is provided from the second thread at the upper end of the external thread of the third threaded rod 32 to the lower end of the external thread in a penetrating manner, so that when the third threaded rod 32 is installed in the first threaded hole 13, the air in the first threaded hole 13 is compressed by the third threaded rod 32 and then discharged through the second ventilation groove 33. At the same time, the second ventilation groove 33 is not provided on the first thread at the uppermost end of the external thread of the third threaded rod 32, so that when the third threaded rod 32 is installed in the first threaded hole 13, the saliva outside is prevented from entering the first threaded hole 13 under the action of the first thread at the uppermost end of the third threaded rod 32. At the same time, when the thread of the third threaded rod 32 is rotated to the last circle, the position of the crown body 31 needs to be adjusted so that the position of the crown body 31 after installation is consistent with the design.

[0053] When in use, the implantation of the composite base 2 is first completed. During implantation, the implant rod 22 is installed in the mounting hole in the patient's frontal bone. During installation, the implant rod 22 can be threadedly connected to the mounting hole in the frontal bone under the action of the external threaded body 24. When the implant rod 22 moves downward in the mounting hole, the air in the mounting hole will be discharged through the first ventilation groove 25, so that the installation of the implant rod 22 is smooth. When the external threaded body 24 is rotated to the last circle, the direction of the connecting head 23 is adjusted to make the direction of the connecting head 23 consistent with the design, so that the implantation of the composite base 2 can be completed. Under the action of the external threaded body 24, the implant rod 22 is firmly implanted on the frontal bone, so that the bridge and the screw 1 can be installed before the implant rod 22 and the frontal bone are completely fused with each other.

[0054] When installing the bridge frame and the screw 1, the front end of the screw body 17 is threadedly connected to the second threaded hole 15, and then the fixing platform 14 is docked on the connecting head 23, and the screw body 17 is continued to be rotated so that the lower end of the screw body 17 is threadedly connected to the third threaded hole 26, and then the screw body 17 is fastened in the third threaded hole 26, and the fixing platform 14 and the connecting head 23 can be fixed together through the screw body 17, so that the composite base 2 is installed on the bridge frame and the screw 1. Since a plurality of bridge frames and screws 1 are provided to cooperate with each other to install the composite base 2, it is ensured that the composite base 2 is stable after installation, and after the installation of the composite base 2 is completed, the crown 3 is installed;

[0055] When installing the dental crown 3, the third threaded rod 32 is threadedly connected to the first threaded hole 13. When the third threaded rod 32 rotates in the first threaded hole 13, the third threaded rod 32 will compress the air in the first threaded hole 13, and the air in the first threaded hole 13 will be discharged through the second ventilation groove 33. At the same time, when the thread of the third threaded rod 32 is rotated to the last circle, the position of the dental crown body 31 needs to be adjusted so that the position of the dental crown body 31 after installation is consistent with the design.
