Description
Technical Field

Background
The oral implantation technology is an advanced and mature technical means for tooth loss restoration, is technically superior to the traditional method, is considered as the first choice restoration scheme for tooth loss, and initially forms expert consensus in the industry, so the oral implantation technology is rapidly popularized and widely applied in the year. As a core product of the oral implantation technology, the dental implant has millions of annual usage in China and is increased by 20% -30% every year, thereby presenting huge market demands and wide development space. At present, a mainstream dental implant system is composed of two sections, wherein a dental implant is implanted into an alveolar bone to play a supporting role, a base station is used for fixing a edentulous prosthesis at the upper end, and the base station is tightly connected with the dental implant in a screw fixing mode, so that a complete dental implant restoration system is formed. Titanium and titanium alloys are the preferred materials for dental implant systems, and the current production mode is dominated by the traditional material reduction machining method.
With the development and progress of 3D printing technology in recent years, its potential advantages in the processing and production of medical products have gradually attracted extensive attention of the industry. Compared with the traditional machining method, the 3D printing technology has the advantages of high machining efficiency, raw material saving, capability of meeting the requirement of personalized shape machining and the like, and has more and more research reports in various medical fields. In the field of dental implant manufacturing, researchers develop technological research. One important research and development idea is to construct a rough and porous structure on the surface of the implant by using the technical characteristics of the 3D printing technology, so as to improve the bonding strength between the implant and the alveolar bone. However, in evaluating the product quality and technical level of a dental implant, in addition to the bonding property of the implant to the bone tissue, the adhesion of the implant to the abutment and the structural stability are important indexes, which directly affect the long-term biological and mechanical stability of the dental implant, and determine the therapeutic effect and the occurrence of complications. According to the requirements of the national pharmaceutical industry standard of titanium and titanium alloy dental implants (YY0315-2016), the geometric dimensional tolerance of each part of the dental implant is + -0.2mm, and the fit clearance between the implant and the abutment is less than 0.035 mm; for the mainstream form of inner taper connection, the inner connection interface of the dental implant and the abutment should be well matched, and the taper deviation should be no more than + -3% of the taper value (i.e. the design value of the drawing) provided by the manufacturer. The machining precision of current titanium alloy laser sintering 3D printing can reach 80 microns, although can satisfy the national industry standard of dental implant overall dimension error, but such machining precision can not satisfy the tolerance fit requirement of implant upper end base platform kneck. Therefore, the precision problem also becomes a technical bottleneck limiting the application of the 3D printing technology in the production and processing of dental implants, and no research report of related solutions is found at present.
Therefore, the problem of precision machining of the connection interface of the abutment at the upper end of the dental implant is a key technical link for determining 3D printing of the dental implant.

The exemplary embodiments and descriptions of the present application are provided herein to explain the present application and not to limit the present application.
As shown in fig. 1, 4, 7, 8 and 9, the present application provides a method for processing a dental implant, which is used to ensure the sealing property and structural mechanical stability of the connection between the dental implant and an abutment, and further meet the precision requirement of a dental implant system, and the method for processing a dental implant comprises:

In practice, the structure of the semi-finished dental implant 430A may be configured in a variety of embodiments. For example, as shown in fig. 7, the semi-finished dental implant 430A may include a body 432 and a blank 431, wherein: the body 432 is provided at an outer side thereof with a thread for coupling with an alveolar bone, and the blank 431 is provided at a top of the body 432.
In a specific implementation, in the step 102: before the lateral wall of centre gripping dental implant semi-manufactured goods embryo body, further include:
101: and processing the neck shape of the semi-finished dental implant product by using 3D printing equipment to obtain a cylindrical blank for clamping.
In a specific implementation, in the step 103: after the top shape of the blank 431 is processed to obtain a connecting cavity 433 for connecting to an abutment, as shown in fig. 8, the semi-finished dental implant 430A is processed into a connectable semi-finished product 430B, so that it can be fixed by a processing tool, thereby completing the subsequent processing steps.
In specific implementation, the fixing of the processing tool and the dental implant can be implemented in various ways. For example, in order to ensure stable connection and facilitate operation, the step 104: the processing tool is inserted into the connecting cavity 433, and the relative position between the dental implant semi-finished product 430A and the processing tool is locked, as shown in fig. 2, the method may further include:
201: the fixing mechanism 410 of the processing tool is inserted into the connecting cavity 433;

In a specific implementation, the side wall of the connection cavity 433 may be provided with a plurality of grooves 434 for anti-rotation.
In one embodiment, the apparatus for processing the top shape of the embryo body 431 can be selected from various embodiments. For example, the step 104: processing the top form of the blank 431 to obtain a connecting cavity 433 for connecting to an abutment may further include: the shape of the top of the blank 431 is processed by a material reducing machining device, and a connecting cavity 433 for connecting the base station is obtained. Specifically, the top form of the blank 431 may be processed by a CNC machining apparatus to obtain the connecting cavity 433 for connecting the abutments.
In an implementation, the top shape of the blank 431 may be processed in various embodiments, for example, in order to ensure the processing precision and further improve the processing efficiency, the step 104: processing the top form of the blank 431 to obtain a connecting cavity 433 for connecting to an abutment, as shown in fig. 3, may further include:

For example, since the cylindrical structure facilitates mechanical clamping, which can ensure high coaxiality between the processed inner cavity and the outer diameter of the cylindrical structure, and ensure stability of mechanical properties without stress concentration, as shown in fig. 7, the blank 431 may be a cylindrical blank, and further, since the diameter of the top of the finished dental implant 430C needs to be slightly larger than the body 432, the diameter of the cylindrical blank is larger than the dental implant body 432 by two millimeters to six millimeters. Further, the circular blank can be formed through 3D printing, so that the shape of the cylindrical blank is effectively guaranteed, and the precision and the efficiency of subsequent processing are improved. For another example, the blank 431 may also be a polygonal cylindrical blank, and the inner diameter of the polygonal cylindrical blank is two millimeters to six millimeters larger than the diameter 432 of the dental implant body. In addition, the polygonal blank can be formed by 3D printing, so that the shape of the polygonal blank is effectively ensured, and the precision and the efficiency of subsequent processing are improved; further, the polygonal cylindrical blank may also be a square cylindrical blank, and the side length of the square cylindrical blank is two millimeters to six millimeters greater than the dental implant body 432.
Further, the height of the cylindrical embryo body can be set in various embodiments. For example, in order to save material and improve processing efficiency while effectively ensuring the accuracy of the finished product 430C, the height of the cylindrical blank 431 is greater than 3 mm.
As shown in fig. 4, 5 and 6, the present application further provides a dental implant processing tool, which is characterized in that the dental implant processing tool includes a fixing mechanism 410 and a connecting bolt 420, wherein:

the connecting bolt 420 can be inserted through the fixing mechanism 410 along the screw hole 411 and screwed into the connecting cavity 433, so as to bolt the fixing mechanism 410 to the dental implant holding semi-finished product 430A.
This processing frock can effectively be fixed in the connection chamber 433 through the bolt in order, and the installation is relatively simple and convenient, and the location is accurate, can realize big batch industrial production, and mechanical precision, roughness all is secure, can satisfy the demand of clinical use.
In specific implementations, the shape of the boss 411 can be configured in various ways. For example, the boss 411 and the connecting cavity 433 may be arranged in parallel walls. For another example, the applicant considers that the taper of the morse taper is very small, a certain torque can be transmitted by using the principle of friction force, and the disassembly is convenient because of the taper fit. In a certain range of the same taper, the workpiece can be freely disassembled and assembled, and the using effect cannot be influenced when the workpiece works. The boss 411 and the connecting cavity 433 may both be disposed in a morse taper.
Secondly, the Morse taper of the boss 413 at the lower end of the fixing mechanism 420 is matched with the dental implant connecting cavity 433, the fixing mechanism 420 is arranged in the dental implant connecting cavity 433, then the connecting bolt 430 is used for fixing the fixing mechanism 420 in vivo, and the tail of the connecting bolt 430 can be tightly connected with the dental implant to form a whole body by screwing down the tail of the connecting bolt 430, so that the fixing mechanism is convenient to clamp.
In particular embodiments, the sidewalls of the bosses 411 may be configured in a variety of embodiments. For example, the side wall of the boss 411 may have a plurality of protrusions 413 arranged in the axial direction to prevent the boss 411 from moving in the circumferential direction within the connection chamber 433. After the convex part 413 enters the interior of the connecting cavity 433 along with the boss 411, the convex part can be effectively clamped in the groove 434 matched with the convex part, so that the convex part and the connecting cavity 433 are circumferentially and relatively fixed.
In summary, the processing method of the dental implant provided by the present application includes: clamping the side wall of the blank 431 of the semi-finished dental implant 430A; processing the top form of the blank 431 to obtain a connecting cavity 433 for connecting the base station; the processing tool is inserted into the connecting cavity 433, and the relative position of the semi-finished dental implant 430A and the processing tool is locked; clamping the processing tool and processing the external shape of the neck of the dental implant to obtain a finished dental implant product 430C. The processing method of the dental implant can effectively overcome the problem that the processing precision of the 3D printed titanium and titanium alloy dental implant at the connecting interface of the neck abutment is not enough, ensures the sealing property and the structural mechanical stability of the connection of the dental implant and the abutment, and further meets the precision requirement of a dental implant system. The application provides a dental implant's processing frock can connect inside the connection chamber 433 at dental implant top, does not need centre gripping dental implant body 432 in the course of working, therefore can effectively overcome 3D and print the destruction influence of centre gripping to implant surface structure in the dental implant secondary machine tooling process, avoids the course of working to the influence of dental implant somatic part, guarantees the precision that dental implant neck subtracts material processing, realizes the standardized batch processing production of product simultaneously.
