Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dental implant interface measuring device. Background Technology

[0002] Dental implants are the core component of dental implant restorations. After being implanted into the alveolar bone, the dental implant integrates with it, and restorative fittings are mounted on top of it. The dental implant supports the restorative fittings. The dental implant assembly 100 consists of a dental implant 102, an implant abutment 101, and a central screw 103. The structure of the implant assembly 100 is as follows: Figure 1 As shown, where, Figure 1 (a) is a structural diagram of the implant components. Figure 1 (b) is a cross-sectional view of the implant assembly. Figure 1 (c) is a schematic diagram of the implant abutment structure. Figure 1 (d) is a schematic diagram of the central screw, as shown below. Figure 1 (e) is a schematic diagram of the dental implant structure; the dental implant 102 and the implant abutment 101 are tapered, and are locked and fixed internally using a central screw 103; the end of the implant abutment 101 is provided with an outer conical surface 1011 and an outer hexagonal surface 1012, as shown in the diagram. Figure 1 As shown in (c); the end of the central screw 103 is provided with a fastening thread 1031 for connecting the dental implant 102, as shown in (c). Figure 1 As shown in (d); the connection between the dental implant 102, the implant abutment 101, and the central screw 103 is called the dental implant interface. The dental implant interface consists of an end face 1024, an inner conical hole 1021, an inner hexagonal hole 1022, and an internal threaded hole 1023, as shown in (d). Figure 1 As shown in (e), during assembly, the internal threaded hole 1023 is threadedly connected to the central screw 103, and the internal hexagonal hole 1022 is fitted to the external hexagonal surface 1012 of the implant abutment 101. The internal hexagonal hole 1022 is used for circumferential positioning of the implant abutment. The internal conical hole 1021 is taperedly connected to the external conical surface 1011 of the implant abutment 101. The internal conical hole 1021 is used to provide support for the external conical surface 1011 of the implant abutment 101 and to transmit occlusal force. In the structure of the dental implant 102, the precision requirements for the dental implant interface are very high. In order to ensure that its superstructure has sufficient aesthetics, good contact performance and mechanical transmission, and accurate occlusion and proximal relationship, the insertion depth of the dental implant interface (i.e., the insertion depth of the implant abutment), whether the size of the internal hexagonal hole 1022 meets the standard, and the length of the dental implant 102 are all parameters that must be measured during the production and inspection of the dental implant 102.

[0003] In related technologies, during the production and testing of dental implants, the measurement methods for various indicators of the implant interface are carried out in a segmented manner. For example, the insertion depth of the implant interface is measured using a coordinate measuring machine or a special internal cone depth measuring instrument in conjunction with a micrometer, or an imaging measuring instrument is used to measure the orifice and combine it with other methods to measure the internal cone angle; the internal hexagonal hole size is measured using a coordinate measuring machine, a special hexagonal go / no-go gauge, or an imaging measuring instrument; the implant length is measured using a micrometer, height gauge, imaging measuring instrument, coordinate measuring machine, etc. The above three measurements are often performed at different inspection stations, and the measurement methods are relatively complex. Moreover, when using the above measurement methods and inspection equipment, some problems will be encountered, such as: the high price of coordinate measuring machine equipment, high operation requirements, and long preparation time; the operation of the internal cone depth measurement gauge combined with micrometer is cumbersome; the conventional method of inserting the hexagonal go-no-go gauge into the interface for measurement is prone to pressing against the implant end face and internal cone hole, causing scratches on the end face and internal cone hole of the dental implant, resulting in the scrapping of the dental implant; the measurement error is large when measuring the internal hole with imaging, and so on.

[0031] A dental implant interface measuring device, such as Figure 2-4 As shown, the device includes: a base 1, a sliding device 2, a first dial indicator 3, a second dial indicator 4, a first auxiliary fixture 5, and a second auxiliary fixture 6. The first dial indicator 3 and the second dial indicator 4 are respectively connected to the base 1. The base 1 is roughly rectangular. Specifically, the first dial indicator 3 and the second dial indicator 4 are fixedly connected to one end of the short side of the rectangular base. The first dial indicator 3 and the second dial indicator 4 are digital dial indicators with preset values. The base 1 is used to support the relevant components. The first auxiliary fixture 5 and the second auxiliary fixture 6 are provided on the base 1. The positions of the first auxiliary fixture 5 and the second auxiliary fixture 6 correspond to the positions of the first dial indicator 3 and the second dial indicator 4, respectively. The first micrometer 3 includes a first data display 31 and a first measuring head 32, and the second micrometer 4 includes a second data display 41 and a second measuring head 42. The sliding device 2 is slidably mounted on the base 1. The first measuring head 32 and the second measuring head 42 respectively abut against the sliding device 2. The dental implant 300 to be tested is installed between the first measuring head 32 and the sliding device 2. The first auxiliary fixture 5 and the second auxiliary fixture 6 are used to fix the first micrometer 3 and the second micrometer 4 respectively to ensure that the positions of the first micrometer 3 and the second micrometer 4 are fixed and do not move, thus ensuring the accuracy of the measurement, and are also used to position the first measuring head 32 and the second measuring head 42.

[0032] The sliding device 2 includes a limiting component 21, a sliding plate 22, and a guide rail 23. The guide rail 23 is connected to the base 1, and the sliding plate 22 is slidably connected to the guide rail 23. Specifically, the bottom surface of the sliding plate 22 is provided with a guide rail slider 224, which is slidably connected to the guide rail 23. When the guide rail slider 224 slides along the guide rail 23, it drives the sliding plate 22 to move along the guide rail 23. In this embodiment, there are 4 guide rail sliders 224, which are evenly distributed at the four corners of the sliding plate 22 to make the force between the sliding plate 22 and the guide rail 23 more uniform and to make the sliding plate 22 slide more smoothly along the guide rail 23. The limiting component 21 is connected to the base 1 and the sliding plate 22 respectively, and the limiting component 21 is used to limit the movement distance of the sliding plate 22.

[0033] The limiting component 21 includes: a tension spring seat 211, a tension spring 212, and an operating handle 213. The tension spring seat 211 is located on the base 1, specifically near the edge of the base 1. The operating handle 213 is located on the slide plate 22. The two ends of the tension spring 212 are connected to the tension spring seat 211 and the operating handle 213, respectively. During operation, when the slide plate 22 moves along the guide rail 23 in a direction away from or towards the tension spring seat 211, the tension spring 212 can limit the movement trajectory of the slide plate 22.

[0034] The slide plate 22 is a cross-shaped slide plate, which includes: a middle plate 221, a first side plate 222, and a second side plate 223. The first side plate 222 and the second side plate 223 are respectively disposed on opposite sides of the middle plate 221. The position of the first side plate 222 corresponds to the first auxiliary fixture 5, and the position of the second side plate 223 corresponds to the second auxiliary fixture 6. The guide rail sliders 224 are evenly distributed on the four corners of the middle plate.

[0035] The first auxiliary fixture 5 includes: a first gauge base 51 and a first pressure plate 52. The first gauge base 51 is connected to the base 1. The upper surface of the first gauge base 51 is provided with a first transverse groove 511. Specifically, the first transverse groove 511 extends horizontally and passes through the long side of the first gauge base 51. The first measuring head 32 is disposed in the first transverse groove 511 and partially protrudes outside the first transverse groove 511. The first pressure plate 52 is installed on the first transverse groove 511 and is used to press the first measuring head 32. The structure of the second auxiliary fixture 6 is the same as that of the first auxiliary fixture 5.

[0036] The first side plate 222 has a measuring groove 2222 on the side near the first auxiliary fixture 5. A positioning groove 2221 is provided within the measuring groove 2222 for clamping the dental implant to be measured. The positioning groove 2221 extends through the upper surface of the first side plate 222. Specifically, the measuring groove 2222 is located on the upper surface of the first side plate 222, and the size of the positioning groove 2221 is adapted to the size of the dental implant to be measured. During measurement, the dental implant to be measured is positioned within the positioning groove. In section 2221, the end face of one end of the dental implant to be tested abuts against the first auxiliary fixture 5; a limiting part 2223 is provided on the side of the first side plate 222 away from the first auxiliary fixture 5, and the limiting part 2223 is blocked on one side of the positioning through groove 2221. Specifically, the limiting part 2223 is provided at the end of the positioning through groove 2221. When the dental implant to be tested is placed in the positioning through groove 2221, the end face of the other end of the dental implant to be tested abuts against the limiting part 2223.

[0037] Specifically, the first measuring head 32 is a multi-functional measuring head. Specifically, the first measuring head 32 includes: a first standard measuring head 321 and a multi-functional measuring terminal 322. One end of the first standard measuring head 321 is connected to the first data display 31, and the other end of the first standard measuring head 32 is connected to the multi-functional measuring terminal 322. Figure 4 As shown, the multifunctional measuring end 322 includes a threaded connection end 3221, a stop step 3222, a measuring head body 3223, and a hexagonal gauge end 3224 connected in sequence. The threaded connection end 3221 is used to connect the multifunctional measuring end 322 to the first standard measuring head 321. When the threaded connection end 3221 is screwed to the end of the first standard measuring head 321, the stop step 3222 limits the screwing depth of the threaded connection end 3221. The connection between the measuring head body 3223 and the hexagonal gauge end 3224 is configured to connect with the dental implant to be tested. The outer conical surface 3225 of the implant 300 is adapted to the inner conical hole 3011 to be measured. The hexagonal dimension of the hexagonal gauge end 3224 is adapted to the hexagonal dimension of the inner hexagonal hole 3012 to be measured of the implant 300. During measurement, by observing whether the hexagonal gauge end 3224 of the multi-functional measuring end 322 can be smoothly inserted into the implant interface of the implant 300 and adapted to the inner hexagonal hole 3012 to be measured, it can be determined whether the hexagonal hole dimension of the implant 300 meets the measurement requirements. The second measuring head 42 is a standard measuring head.

[0038] like Figure 5 The diagram shown is a structural representation of the dental implant 300 to be tested. Figure 5 (a) is a cross-sectional view of the dental implant to be tested. Figure 5 (b) is a front view of the dental implant to be tested. The dental implant 300 to be tested includes a main body 301 and a conical tail screw 202. The conical tail screw 202 is connected to the tail end of the main body 301. By setting the conical tail screw 202, the dental implant 300 to be tested can be more easily aligned with the hexagonal gauge end 3224 of the multi-functional measuring end 322 during measurement. At the same time, before the dental implant product leaves the factory, the conical tail screw 202 fixes the dental implant product in the packaging container, which can realize non-contact packaging of the dental implant and avoid contamination of the dental implant. Specifically, the conical tail screw 202 includes a milled flattening structure, which comprises two parallel milled flattening surfaces 2021. These two milled flattening surfaces 2021 are parallel to two planes of the internal hexagonal hole 3012 of the implant 300 to be tested. When the implant 300 is inserted into the positioning slot 2221, the direction of the milled flattening surfaces 2021 can be adjusted to align with the hexagonal gauge end 3224 of the multi-functional measuring end 322, allowing the multi-functional measuring end 322 to be quickly inserted into the implant interface of the implant 300. Figure 5As shown in (a), the interface of the dental implant to be tested includes: the end face to be tested 3014, the inner conical hole to be tested 3011, the inner hexagonal hole to be tested 3012, and the inner threaded hole to be tested 3013. This setting can prevent the end face to be tested 3014 from being damaged or scratched by the multi-functional measuring end 322 during the measurement process, thereby improving the product yield.

[0039] During calibration, the measuring device is calibrated using a calibration piece 200 of known length. The shape of the calibration piece 200 is identical to that of the corresponding model of the dental implant 300 to be tested. Figure 6 The diagram shown is a structural diagram of the calibration component, in which, Figure 6 (a) is a front view of the calibration piece. Figure 6 (b) is a cross-sectional view of the calibration piece. Figure 6 (c) is a three-dimensional structural diagram of the calibration piece. The length of the calibration piece 200 is pre-measured using a micrometer or other high-precision measuring equipment. The calibration piece 200 includes a solid part 201 and a conical tail screw 202. The solid part 201 does not have a dental implant interface. Figure 6 As shown in (b), the tail end of the calibration piece 200 is also provided with a conical tail pin 202. The conical tail pin 202 includes two parallel milled flat surfaces 2021. The calibration piece 200 is installed into the positioning through groove 2221. The two ends of the calibration piece 200 abut against the first auxiliary fixture 5 and the limiting part 2223 respectively. During calibration, the reading of the second data display 41 is set to the length of the calibration piece 200. During measurement, the dental implant 300 to be tested is installed. One end of the dental implant 300 to be tested abuts against the first auxiliary fixture, and the other end of the dental implant to be tested abuts against the limiting part 2223. The slide moves along the guide rail, driving the second side plate 223 to abut against the second measuring head 42. At this time, the displayed value of the second data display 41 is the length of the dental implant to be tested.

[0040] The base 1 is also provided with a stop screw 8. Specifically, the stop screw 8 is located on the upper surface of the base 1 at the edge away from the tension spring seat 211. The stop screw 8 and the tension spring seat 211 are used to limit the movement trajectory of the slide plate 22. During operation, the slide plate 22 moves towards the stop screw 8 until the slide plate 22 abuts against the stop screw 8 and stops moving, or the slide plate 22 moves away from the stop screw 8 until the slide plate 22 abuts against the tension spring seat 211 and stops moving.

[0041] The measuring device also includes a support frame 7, which is located on the side of the base 1 away from the slide plate 22. The support frame 7 is used to place the dental implant interface measuring device at an inclined angle, which makes it easier to read the first dial indicator 3 and the second dial indicator 4 and operate the measuring device.

[0042] In a specific embodiment, the measuring device is calibrated using the calibration component 200. A schematic diagram of the device during calibration is shown below. Figure 7 As shown, Figure 7 The calibration piece 200 is cross-sectionally processed. The operating handle 213 is pulled to move the slide away from the tension spring seat 211, inserting the calibration piece 200 into the positioning slot 2221. Both ends of the calibration piece 200 abut against the first gauge base 51 and the limiting part 2223, respectively. The hexagonal gauge end 3224 abuts against the upper end face of the calibration piece 200. The second measuring head 42 abuts against the second side plate 223. The reading on the first data display 31 is set to zero, and the reading on the second data display 41 is set to the length of the calibration piece 200. The operating handle 213 is pulled again to move the slide away from the tension spring seat 211, and the calibration piece 200 is removed. The calibration is complete. A schematic diagram of the measurement device is shown below. Figure 8 As shown, Figure 8 The dental implant 300 to be tested is cross-sectionally processed. The operating handle 213 is pulled, causing the sliding plate 22 to move away from the tension spring seat 211, thus inserting the dental implant 300 into the positioning slot 2221. The operating handle 213 is slowly released, and the sliding plate 22 moves towards the tension spring seat 211 under the action of the tension spring 212, moving the dental implant 300 towards the first measuring head 32 until it is aligned with the measuring end face 3014 of the dental implant 300 and the first measuring base. When 51 abuts, the first measuring head 32 extends into the implant interface of the implant 300 to be tested. If the first measuring head 32 can be adapted to the internal hexagonal hole 3012 of the implant 300 to be tested, then the size of the internal hexagonal hole 3012 of the implant 300 to be tested can meet the measurement standard. At this time, the reading of the first data display 31 is the insertion depth of the implant interface, and the reading of the second data display 41 is the length of the implant 300 to be tested.

[0043] The present invention discloses a dental implant interface measuring device, comprising: a base, a sliding device, a first dial indicator, a second dial indicator, a first auxiliary fixture, and a second auxiliary fixture. The first dial indicator and the second dial indicator are respectively connected to the base. The first auxiliary fixture and the second auxiliary fixture are provided on the base, and the positions of the first auxiliary fixture and the second auxiliary fixture correspond to the positions of the first dial indicator and the second dial indicator, respectively. The first dial indicator includes a first data display and a first measuring head, and the second dial indicator includes a second data display and a second measuring head. The sliding device is slidably disposed on the base, and the first measuring head and the second measuring head abut against the sliding device. The dental implant to be measured is installed between the first measuring head and the sliding device. In this technical solution, the measuring head of the first dial indicator is modified into a multi-functional measuring head with a hexagonal gauge end. The hexagonal dimensions of the hexagonal gauge end are adapted to the hexagonal dimensions of the hexagonal hole of the corresponding dental implant to be tested. By observing whether the hexagonal gauge end of the first measuring head can be smoothly inserted into the implant interface of the dental implant to be tested, it can be determined whether the hexagonal hole size of the implant meets the measurement requirements. It also enables simultaneous measurement of the implant interface insertion depth and implant length, improving measurement efficiency and preventing the implant end face from being damaged or scratched during the measurement process, thus improving operational convenience. Furthermore, the first and second dial indicators can be used to directly read the implant interface insertion depth and implant length. Moreover, the first and second dial indicators can be connected to a computer to directly import the measurement data into an electronic spreadsheet for testing records.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent modifications or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
