Description

Technical Field

[0001] The invention relates to the technical field of dental implant processing, and in particular to a dental implant abutment coloring device. Background Art

[0002] Dental implant abutments are essential dental implant accessories during the dental implant process. They are usually made of titanium alloy, with a small shape but a complex structure. Since the color of titanium alloy is metallic silver-gray, after being implanted in the oral cavity, it will cause the gingival gray line and the color of the implanted gingiva to be dark, affecting the appearance. At present, the commonly used coloring processes for titanium alloy abutments are nitriding and anodizing. Titanium alloy anodizing has low process requirements, is simple and cheap, and has good coloring effect and is widely used.

[0003] Part of the outer surface of the dental implant abutment body is anodized to distinguish different specifications of dental implant abutments through anodizing coloring process. The lower hexagonal retention part and the position where the gingival connection with the hexagonal are not anodized to ensure a good biological sealing effect after the abutment and implant are in contact to avoid microbial invasion.

[0004] The prior art provides a base coloring and fixing device, which includes a base body and a sealing sleeve independently arranged relative to the base body, wherein the base body includes a conductive bottom plate and an elastic fixing plate arranged on the upper layer of the conductive bottom plate, wherein the elastic fixing plate is provided with at least one retaining through hole, and the bottom of the retaining through hole is sealed and abutted against the conductive bottom plate. Such a base coloring and fixing device has some problems, such as: the workpiece fixing positions of the device are dense, and the workpiece at the center of the device is far away from the cathode, resulting in poor ion flow near the center workpiece and uneven acid etching; and the conductive chuck and the conductive bottom plate are directly exposed to the anodic oxidation medium, and the energized bottom plate will also be colored, thereby reducing its conductivity. Summary of the invention

[0005] The technical solution aims to provide a dental implant abutment coloring device to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0006] A dental implant abutment coloring device comprises a box body, a box cover, an anode connection seat, a cathode disk and a plurality of connection posts, wherein the upper side of the box body has an opening, the box cover is adapted to the opening, the anode connection seat is connected to the box cover, a plurality of conductive joints are provided on the lower surface of the anode connection seat, the upper end of the connection post is provided with a plug hole adapted to the conductive joint, the lower end of the connection post is provided with a base mounting hole, the surface of the connection post is insulated, the plug hole and the base mounting hole are electrically connected via a conductive member contained in the connection post, and the cathode disk is located below the anode connection seat.

[0007] The anode connection seat is connected to the box cover and is located in the upper space inside the box body, while the cathode disk is located in the lower space inside the box body. The installation position of the base is extended downward from the anode connection seat to the vicinity of the cathode disk through the connection column. When in use, only the amount of anodic oxidation liquid added is controlled so that it does not cover the base to be treated, so as to avoid the problem of the anode connection seat being oxidized and its conductivity being reduced. Since the cathode adopts a disc-shaped component, the distance from each connection column to the cathode disk is kept uniform, thereby avoiding uneven coloring caused by poor ion mobility near the base. The connection column and the conductive connector are plug-in connections, so that the user can adjust the number of connection columns according to the number of bases to be colored to avoid unnecessary oxidation of the device structure.

[0008] Furthermore, the abutment mounting hole includes an upper region and a lower region, the upper region is provided with an internal thread, and the inner cavity of the lower region can wrap the non-colored region of the abutment to be colored. By simulating the connection scheme when the implant is mounted on the abutment, the abutment can be fully fixed at the lower end of the connecting column, avoiding the abutment from shaking during the coloring process and causing uneven coloring.

[0009] Furthermore, a reserved groove is provided in the middle of the upper surface of the box cover for the connection column to pass through, and the anode connection seat is embedded and connected to the reserved groove. The embedded connection is formed by the cooperation of the limiting boss protruding downward from the bottom of the anode connection seat and the reserved groove. The outer contour of the limiting boss is adapted to the inner contour of the reserved groove. This detachable connection method simplifies the overall structure of the dental implant abutment coloring device. It is not as large and cumbersome as the traditional anodizing coloring device, but can be used in outpatient clinics and dental hospitals under non-laboratory conditions. This means that the coloring process of the abutment can be carried out after it is sold to consumers, which improves the customization of the abutment product and further reduces the customization requirements of the processing factory that produces the abutment. At the same time, by pulling the anode connection seat out of the reserved groove, there is no need to open the box cover, and the connection column and the abutment can be directly taken out.

[0010] Furthermore, the cathode disk is connected to the box cover. The anode connection seat and the cathode disk are all connected to the box cover, and each time the box cover is opened to assemble the base and the connection column, the cathode disk can be checked for damage, aging, and other problems.

[0011] Furthermore, the cathode disk is provided with a plurality of through drainage holes. Based on the premise that the cathode disk is fixed to the box cover, the drainage holes can drain the anodic oxidation liquid smoothly when the dental implant abutment coloring device completes the coloring process and takes out the abutment.

[0012] Furthermore, the edge of the cathode disk is provided with an upwardly turned edge, and the height of the edge is greater than the distance from the base mounting hole to the cathode disk. During anodization, electrons tend to concentrate at the place closest to the plate, and electron mobility in other places is poor, which may cause uneven coloring. The height of the turned edge is preferably able to cover the installed base, so that the base can be colored more evenly during the anodization process.

[0013] Furthermore, the side wall of the box body has a transparent area for observing the interior of the box body, so that the internal situation of the device can be observed at any time during the anodizing process.

[0014] Furthermore, a liquid level mark is provided on the transparent area of ​​the side wall of the box body to provide a reminder of the amount of anodizing liquid to be added to the user, thereby avoiding excessive addition that causes the anode connection seat to contact the anodizing liquid and be oxidized.

[0015] Furthermore, the box made of high molecular hard transparent material can better observe the entire anodizing coloring process, can make the personalized treatment more transparent, and is suitable for use in outpatient clinics, dental hospitals and other places.

[0016] The present invention has the following advantages:

[0017] I. It can prevent the anode connection seat from contacting with the anode oxidation liquid, thus preventing the anode connection seat from being oxidized and causing its conductivity to decrease;

[0018] II. Ensure the uniformity of the distance from each base to the cathode, thereby avoiding uneven coloring caused by poor ion mobility near the base;

[0019] III. The connection between the connecting column and the conductive connector is plug-in, which is convenient for disassembly, assembly and adjustment, and avoids unnecessary oxidation of the device structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 In the embodiment shown, a dental implant abutment coloring device comprises a box body 010, a box cover 020, an anode connection seat 030, a cathode disk 040 and a plurality of connection posts 050. The upper side of the box body 010 has an opening 011, and the box cover 020 is adapted to the opening 011. The anode connection seat 030 is connected to the box cover 020, and an anode connection 032 is provided on the upper side surface of the anode connection seat 030, and a plurality of conductive connectors 031 are provided on the lower side surface of the anode connection seat 030. Figure 1 and 2 As shown, the upper end of the connecting column 050 is provided with a plug hole 051, so that it can be plugged and fixed with the conductive connector 031 through the plug hole 051; the lower end of the connecting column 050 is provided with a base mounting hole 052, so that the base 060 can be fixed on the lower end surface of the connecting column 050. The surface of the connecting column 050 is insulated, and the plug hole 051 and the base mounting hole 052 are electrically connected through the conductive member 053 contained in the connecting column 050. The cathode disk 040 is located below the anode connection seat 030. The cathode disk 040 and the anode connection seat 030 are parallel to each other and have similar sizes, so that there are cathodes with similar distances and areas near each base 060 to be colored, so that the overall coloring effect is uniform.

[0029] When in use, anodizing liquid is injected into the box 010. Since the anode connection seat 030 is located in the upper space inside the box 010, and the cathode disk 040 is located in the lower space inside the box 010, the installation position of the base 060 is extended downward from the anode connection seat 030 to the vicinity of the cathode disk 040 through the connecting column 050, so that the user can make the liquid surface of the anodizing liquid submerge the base 060 to be treated without contacting the anode connection seat 030, thereby avoiding the problem of the anode connection seat 030 being oxidized and causing its conductivity to decrease. Since the cathode adopts a disc-shaped component 040, the distance between each connecting column 050 and the cathode disk 040 is kept uniform, so that each base 060 to be colored has good ion flowability, which is conducive to uniform coloring. The connecting column 050 and the conductive joint 031 are plug-in connections, so that the user can adjust the number of connecting columns 050 according to the number of bases 060 to be colored, avoiding unnecessary oxidation of the device structure.

[0030] As a further preferred embodiment, Figure 3 and 4 As shown, the base mounting hole 052 includes an upper section area 052-1 and a lower section area 052-2, the upper section area 052-1 is provided with an internal thread, and the inner cavity of the lower section area 052-2 can wrap the non-colored area of ​​the base 060. By simulating the connection scheme of fixing the base 060 with the central screw 070 when the implant is installed, the base 060 is inserted into the lower end area 052-2 so that the non-colored area is completely wrapped by the base mounting hole 052, and then the central screw 070 is used to penetrate the mounting hole in the middle of the base 060 and is threadedly connected and fixed with the upper section area 052-1, so that the base 060 can be fully fixed at the lower end of the connecting column 050, so as to prevent the base 060 from shaking during the coloring process and causing uneven coloring.

[0031] As a further preferred embodiment, Figure 1As shown, the middle part of the upper surface of the box cover 020 is provided with a reserved groove 021 for the connection column 050 to pass through, and the anode connection seat 030 is partially embedded in the reserved groove 021 to achieve relative fixation with the box cover 020. This relative fixation is achieved by the limit boss protruding downward from the bottom of the anode connection seat 030 and the reserved groove 021. The outer contour of the limit boss is adapted to the inner contour of the reserved groove 021. This detachable connection method simplifies the overall structure of the dental implant base coloring device, which is not as large and cumbersome as the traditional anodizing coloring device, but can be used in outpatient clinics and dental hospitals under non-laboratory conditions. This means that the coloring process of the base can be carried out after it is sold to consumers, while improving the customization of the base product, and further reducing the customization requirements of the processing factory producing the base. At the same time, by pulling out the anode connection seat 030 from the reserved groove 021, the connection column 050 and the base 060 can be taken out without opening the box cover 020.

[0032] As a further preferred embodiment, Figure 2 As shown, the cathode disk 040 is connected to the box cover 020 through a bracket 042. The anode connection seat 030 and the cathode disk 040 are both connected to the box cover 020. Every time the box cover 020 is opened to assemble the base 060 and the connecting column 050, the cathode disk 040 can be checked for damage, aging and other problems.

[0033] As a further preferred embodiment, Figure 1 As shown, the cathode disk 040 is provided with a plurality of through drainage holes 041. Based on the premise that the cathode disk 040 is fixedly connected to the box cover 020, the drainage holes 041 can smoothly drain the anodic oxidation liquid when the dental implant abutment coloring device completes the coloring process and takes out the abutment 060.

[0034] As a further preferred embodiment, Figure 1 As shown, the edge of the cathode disk 040 is provided with an upwardly turned surrounding edge 044. The surrounding edge 044 of a reasonable height can surround the base 060 so that the base 060 is more evenly colored during the anodizing process.

[0035] As a further preferred embodiment, Figure 1 and 2As shown, the side wall of the box 010 has a transparent area for observing the inside of the box, so that the internal situation of the device can be observed at any time during the anodizing process. A more preferred embodiment is that the transparent area of ​​the side wall of the box 010 is provided with a liquid level mark 012 to provide a reminder of the amount of anodizing liquid to be added for the user to avoid excessive addition that causes the anode connector 030 to contact the anodizing liquid and be oxidized. A more preferred embodiment is that the box 010 is made of a polymer hard transparent material, which can better observe the entire anodizing coloring process, make personalized processing more transparent, and is suitable for use in outpatient clinics and dental hospitals.
