Description

Technical Field

[0001] The present invention relates to the field of oral medical technology, and in particular to an implant position measurement device. Background Art

[0002] Dental implant is a method of restoring missing teeth based on the lower structure implanted in the bone tissue to support and fix the upper dental restoration. This repair method is mainly aimed at the treatment of tooth defects and missing teeth. Dental implant requires that the implant with high compatibility with human bone be implanted into the alveolar bone of the missing tooth area by means of a minor surgical operation. When the implant is tightly fitted with the alveolar bone, the prepared crown is fixed to the alveolar bone of the human body through the implant. In order to accurately match the implanted tooth with the original dentition in the patient's mouth, it is necessary to obtain the precise position of the implant implant. Since the implant needs to be implanted in the alveolar bone, it is difficult to accurately and conveniently detect the precise position of the implant implant. Although CT can be used to obtain the implant position of the implant in the human body, CT irradiation has a certain amount of radiation, which may affect human health, and the method of measuring the implant position of the implant by CT is low in accuracy and cannot meet the requirements of accurate matching of the implanted tooth with the original dentition in the patient's mouth.

[0033] Embodiment 1:

[0034] This embodiment provides an implant posture measurement device, which includes an implant posture measurement tool, a binocular camera and a processing circuit.

[0035] like Figure 1 , Figure 2 and Figure 8 As shown, the detection tool includes an auxiliary positioning member 10 and an intermediate connecting member 20. The above-mentioned implant 30 posture refers to the position of a selected reference point on the implant 30 in three-dimensional space and the axial direction ( Figure 1 The posture of the implant 30 in three-dimensional space is defined by the x-direction.

[0036] like Figure 6 As shown, the auxiliary positioning member 10 is provided with a signal reflection pattern 14 and a first connection structure for three-dimensional spatial posture recognition;

[0037] The signal reflection pattern 14 is made of a material that can reflect signals that can be sensed by relevant acquisition equipment. The signal reflected by the signal reflection pattern 14 can be an electromagnetic signal, an optical signal, an acoustic wave signal, etc., which is not limited here. According to an optional but advantageous embodiment, the signal reflection pattern 14 is made of a material that can reflect infrared light. The signal acquisition equipment can collect at least a portion of the signal reflected by the signal reflection pattern 14, and obtain the position and posture of the signal reflection pattern 14 in three-dimensional space based on the collected signal. Since the position and posture of these signal reflection patterns 14 on the auxiliary positioning member 10 are fixed after the auxiliary positioning member 10 is manufactured, after knowing the position and posture of the signal reflection pattern 14 in three-dimensional space, the position and posture of the auxiliary positioning member 10 in three-dimensional space are also known.

[0038] According to an optional but advantageous implementation, the present embodiment commonly uses a binocular infrared camera as a signal acquisition device for collecting infrared signals reflected by the reflection pattern. The infrared signal reflected by the signal reflection pattern 14 forms an infrared image including the aforementioned signal reflection pattern 14 through the binocular infrared camera. The computer obtains the position and posture of the signal reflection pattern 14 in three-dimensional space based on the aforementioned infrared image. The aforementioned method of obtaining the position and posture of the signal reflection pattern 14 in three-dimensional space based on the infrared image can adopt the existing technology, which will not be elaborated here.

[0039] In this embodiment, a second connection structure is disposed at one end of the intermediate connection member 20, and a third connection structure is disposed at the other opposite end. The intermediate connection member 20 and the auxiliary positioning member 10 are connected to each other in a fixed relative position through the first connection structure and the second connection structure.

[0040] The aforementioned fixed relative position means that the auxiliary positioning member 10 cannot rotate in directions other than the axial direction of the intermediate connecting member 20, and in the axial direction of the intermediate connecting member 20, the position of the auxiliary positioning member 10 relative to the intermediate connecting member 20 remains unchanged.

[0041] The connecting member and the implant 30 are connected in a fixed relative position through a third connecting structure. The fixed relative position means that the intermediate connecting member 20 cannot rotate in any direction other than the axial direction of the implant 30, and the position of the intermediate connecting member 20 relative to the implant 30 remains unchanged in the axial direction of the implant 30.

[0042] Since the first connection structure and the second connection structure are respectively arranged at opposite ends of the intermediate connection member 20 in this embodiment, the implant 30 and the auxiliary positioning member 10 can be connected to the intermediate connection member 20 at both sides of the intermediate connection member 20. In this way, the implant 30 and the auxiliary positioning member 10 can be connected to the intermediate connection member 20 conveniently and quickly without affecting each other.

[0043] After being connected through the intermediate connecting piece 20, when detecting the position and posture of the auxiliary positioning piece 10 in three-dimensional space, the position and posture of the auxiliary positioning piece 10 relative to the implant 30 remain fixed and known, and the shapes and sizes of the auxiliary positioning piece, the intermediate connecting piece and the implant are also known and fixed. Therefore, combined with the relative position between the auxiliary positioning piece and the intermediate connecting piece, the relative position of the intermediate connecting piece and the implant, and the shapes and sizes of the auxiliary positioning piece, the intermediate connecting piece and the implant can accurately obtain the position and posture of the implant 30 in three-dimensional space based on detecting the position and posture of the auxiliary positioning piece 10 in three-dimensional space.

[0044] In specific implementation, a binocular camera is used to collect the signal reflected by the signal reflection pattern 14 and process it to obtain image data. The binocular camera sends the image data to the processing circuit, and the processing circuit processes the image data to obtain the position and posture of the signal reflection pattern 14 in the three-dimensional space. The above-mentioned method of calculating the position and posture of the signal reflection pattern 14 in the three-dimensional space according to the image data of the signal reflection pattern 14 can adopt the existing technology, which will not be repeated here.

[0045] Since the auxiliary positioning member 10 and the signal reflection pattern 14 have a fixed positional relationship, and the structural dimensions of the auxiliary positioning member 10 are determined, the processing circuit can infer the position of the auxiliary positioning member 10 in three-dimensional space according to the position of the signal reflection pattern 14 in three-dimensional space. Since the structural dimensions of the auxiliary positioning member 10 and the intermediate connector 20 are determined, and the positions of the intermediate connector 20 and the auxiliary positioning member 10 are fixed after the intermediate connector 20 and the auxiliary positioning member 10 are connected, the processing circuit can infer the position of the intermediate connector 20 in three-dimensional space according to the position of the auxiliary positioning member 10 in three-dimensional space. Similarly, since the structural dimensions of the intermediate connector 20 and the implant 30 are determined, and the positions of the intermediate connector 20 and the auxiliary positioning member 10 are fixed after the intermediate connector 20 and the implant 30 are connected, the processing circuit can infer the position of the intermediate connector 20 in three-dimensional space according to the position of the auxiliary positioning member 10 in three-dimensional space.

[0046] In order to quickly calculate the position and posture of the implant 30 in three-dimensional space, the processing circuit in this embodiment can directly call the three-dimensional model data of the auxiliary positioning member 10, the intermediate connecting member 20 and the implant 30, and directly calculate the position and posture of the implant 30 in three-dimensional space according to the position and posture of the detected reflection pattern in three-dimensional space and the aforementioned three-dimensional model data.

[0047] The aforementioned processing circuit includes a processor. The processor may be a central processing unit (CPU), other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc., and may also be configured to implement one or more integrated circuits of the embodiments of the present invention.

[0048] The aforementioned processing circuit also includes a memory, wherein the memory may include a memory for data or instruction storage. For example, but not limitation, the memory may include a hard disk drive (HDD), a floppy disk drive, a flash memory, an optical disk, a magneto-optical disk, a tape or a universal serial bus (USB) drive or a combination of two or more of these. In appropriate cases, the memory may include a removable or non-removable (or fixed) medium. In appropriate cases, the memory may be inside or outside the data processing device. In a specific embodiment, the memory is a non-volatile solid-state memory. In a specific embodiment, the memory includes a read-only memory (ROM). In appropriate cases, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM) or a flash memory or a combination of two or more of these.

[0049] The aforementioned processing circuit also includes a communication module, the communication module is electrically connected to the processor, and the communication module is used to receive image data sent by the binocular camera. The communication module can be either a wireless communication module or a wired communication module, which is not limited here.

[0050] The communication module described in this embodiment includes but is not limited to, for example, RS-485 communication module and / or RS-232 and / or PLC communication module and / or WiFi communication module and / or RF Mesh communication module and / or ZigBee communication module and / or ZWave communication module and / or NB-IoT communication module and / or eLTE-IoT communication module and / or TCP / IP communication module and / or USB communication module and / or micro USB communication module and / or Type-C communication module and / or 2G and / or 3G and / or 4G and / or 5G communication module.

[0051] As an optional but advantageous implementation, the processing circuit in this embodiment may adopt a PC (Personal computer), and the communication module may adopt a USB 3.0 communication module.

[0052] like Figure 3 and Fig. 9As shown, as one of the optional but advantageous implementations, in this embodiment, the first connecting structure includes a first connecting member 11 and a first limiting surface 12, the first connecting member 11 is provided with a first thread 111, the second connecting structure includes a second thread 21 and a second limiting surface 22, the first thread 111 cooperates with the second thread 21, and the first limiting surface 12 is used to limit the axial position of the auxiliary positioning member 10 and the intermediate connecting member 20 when abutting against the second limiting surface 22.

[0053] The first thread 111 and the second thread 21 cooperate to keep the auxiliary positioning member 10 and the intermediate connecting member 20 in a relatively precise coaxiality, thereby realizing the precise positioning of the intermediate connecting member 20 in the axial direction. After the first limiting surface 12 and the second limiting surface 22 abut against each other, the axial position of the auxiliary positioning member 10 and the corresponding intermediate connecting member 20 is also limited, so that the auxiliary positioning member 10 and the intermediate connecting member 20 form a connection with a fixed relative posture.

[0054] like Figure 3 and Fig. 9 As shown, the first connecting member 11 can be a screw, one end of the screw is provided with an external thread, and correspondingly, the middle connecting member 20 is provided with a threaded hole at one end facing the auxiliary positioning, and the thread of the threaded hole matches the external thread of the aforementioned screw. In order to facilitate installation, the present embodiment can also provide a through hole in the auxiliary positioning member 10, a limiting surface is provided in the through hole, and a limiting surface is provided on the head of the screw accordingly. During installation, the screw is inserted into the through hole of the auxiliary positioning member 10, and the end of the screw with the thread passes through the position of the limiting surface in the through hole. After the screw is connected to the middle connecting member 20, the limiting surface on the screw is tightly pressed against the limiting surface in the through hole.

[0055] like Figure 3 and Figure 4As shown, as an optional but advantageous embodiment, in this embodiment, the third connection structure includes a third thread 23 and a first boss 24 with a conical outer wall, the third thread 23 matches at least a portion of the internal thread 32 of the implant 30, and at least a portion of the first boss 24 is used to abut against the conical inner wall 31 of the implant 30. The aforementioned implant 30 can be provided with a threaded hole, and the conical inner wall 31 is connected to the threaded hole. During installation, the intermediate connector 20 is inserted into the hole of the implant 30, and the third thread 23 is connected to the internal thread 32 in the threaded hole of the implant 30. During the insertion process, the conical surface of the first boss 24 abuts against the conical inner wall 31 in the implant 30. The conical surface of the first boss 24 and the conical inner wall 31 of the implant 30 can be used to maintain good concentricity between the intermediate connecting member 20 and the implant 30. After the first boss 24 abuts against the conical inner wall 31, the axial position between the intermediate connecting member 20 and the implant 30 is also limited, so that the auxiliary positioning member 10 and the intermediate connecting member 20 form a connection with a fixed relative posture.

[0056] like Figure 4 As shown, as an optional embodiment, in this embodiment, the third connection structure includes a second connecting member 25, the third thread 23 is arranged on the second connecting member 25, the intermediate connecting member 20 is provided with a mounting hole 26, the mounting hole 26 is provided with a first clamping surface 261, and the second connecting member 25 is provided with a second clamping surface 251, the second connecting member 25 has one end of the third thread 23 passing through the mounting hole 26 and being threadedly connected to the implant 30, and the second clamping surface 251 of the second connecting member 25 is pressed against the first clamping surface 261.

[0057] The second connecting member 25 can be a screw, and the third thread 23 is provided at the end of the screw facing the implant 30. When the second connecting member 25 is threadedly connected to the implant 30, the second pressing surface 251 is used to press the first pressing surface 261 to fix the axial position between the intermediate connecting member 20 and the implant 30.

[0058] Example 2

[0059] For certain brands or types of implants 30 , in addition to measuring the axial direction of the implant 30 and the position of the selected reference point, it is also necessary to obtain the angular position of the implant 30 in its circumferential direction.

[0060] In this regard, in the present embodiment, the third connection structure also includes a first angular position limiting structure, which is used to cooperate with the angular position limiting structure of the implant 30 to limit the relative angular position of the intermediate connection member 20 and the implant 30 in the circumferential direction of the implant 30. An angular position identification structure is also provided on the intermediate connection member 20, and there is a preset angular position relationship between the angular position identification structure and the first angular position limiting structure.

[0061] For the convenience of describing the present document, the angular position limiting structure provided on the implant 30 is referred to as the fourth angular position limiting structure. The aforementioned first angular position limiting structure provided on the intermediate connection member 20 and the fourth angular position limiting structure provided on the implant 30 match each other, so that after the intermediate connection member 20 is connected to the implant 30, it cannot rotate around the axis of the implant 30, so that the angular position of the intermediate connection member 20 relative to the implant 30 in the circumferential direction can remain unchanged.

[0062] In order to conveniently identify the angular position of the intermediate connector 20 after being connected to the implant 30, the present embodiment further provides an angular position identification structure, the structural feature of which can identify the angular position of the intermediate connector 20 rotated around the axial direction of the implant 30. In addition, the present embodiment can make the angular position identification structure and the first angular position limiting structure form a certain preset angle, that is, there is a preset angular position relationship between the position identification structure and the first angular position limiting structure, and the angle is used as a known condition. After the angular position of the intermediate connector 20 identified by the angular position identification structure is identified, the angular position of the implant 30 in its circumferential direction can be calculated based on the preset angular position relationship between the known angular position identification structure and the first angular position limiting structure.

[0063] In this embodiment, the first angular position limiting structure and the fourth angular position limiting structure are capable of preventing the intermediate connecting member 20 from moving relative to the implant 30 in the circumferential direction ( Figure 1 The structure is a structure that rotates in the a direction (in the middle), and this type of structure includes but is not limited to a structure with a polygonal cross-section, a structure with an elliptical cross-section, and a structure with a non-circular cross-section.

[0064] like Figure 5 As shown, as an optional but advantageous implementation, in this embodiment, the first angular position limiting structure includes a first plane 27, and the angular position identifying structure includes a second plane 28, and the first plane 27 and the second plane 28 are parallel to each other.

[0065] In this embodiment, the angular position identification structure is set in the form of a plane, which is conducive to precise processing and forming on the one hand, and can quickly and accurately identify the normal direction of the second plane on the other hand. According to the normal direction of the first plane 27, the angular position of the second plane 28 in space can be simply and accurately known. At the same time, the application sets the first angular position limiting structure to a first plane 27 that is parallel to the second plane 28, so that the normal directions of the first plane 27 and the second plane 28 are the same, and the angular position of the intermediate connector 20 relative to the circumferential direction of the implant 30 can be directly obtained through the normal direction of the second plane 28, which can simplify the identification process of the angular position of the implant 30 and make the identification result more accurate.

[0066] As a preferred embodiment, the first plane 27 is parallel to the axis of the implant 30. After adopting the above-mentioned scheme, the normal direction of the second plane 28 is parallel to the axial direction of the implant 30. The angular position of the implant 30 in its circumferential direction can be directly obtained through the normal direction of the first plane 27, so that the process of identifying the angular position of the implant 30 is further simplified.

[0067] like Figure 7 As shown, in this embodiment, the intermediate connecting member 20 includes a first component 291 and a second component 292, the second connecting structure is arranged on the first component 291, the first component 291 is provided with a second angular position limiting structure 2911, and the second component 292 is provided with a third angular position limiting structure 2921, and the angular position between the first component 291 and the second component 292 in the circumferential direction of the second component 292 is limited by the second angular position limiting structure 2911 and the third angular position limiting structure 2921.

[0068] In this embodiment, the intermediate connector 20 is divided into two parts, and the angular position relationship between the two parts in the circumferential direction is limited by the second angular position limiting structure 2911 and the third angular position limiting structure 2921. The second angular position limiting structure 2911 and the third angular position limiting structure 2921 are structures that can prevent the first component 291 from rotating relative to the second component 292 in the circumferential direction. Such structures include but are not limited to structures with polygonal cross-sections, structures with elliptical cross-sections, and structures with non-circular cross-sections. The aforementioned first angular position identification structure can be set on the first component 291, so that the first component 291 and the second component 292 can be assembled together to form the intermediate connector 20 in position after the first angular position identification structure is accurately machined on the first component 291.

[0069] like Figure 5As shown, as an optional but advantageous embodiment, in this embodiment, a feature that facilitates the identification of the intermediate connector 20 can also be set on the intermediate connector 20, for example, a groove 2912 that is recessed in a direction away from the auxiliary positioning member 10 can be set at one end of the first component 291 facing the auxiliary positioning member 10. Since the aforementioned recessed groove 2912 is set at one end facing the auxiliary positioning member 10, when the intermediate connector 20 is connected to the implant 30 in the patient's mouth, the groove 2912 feature is exposed outside the alveolar bone and can be easily collected by the collection device. The shape of the groove 2912 area is significantly different from other parts around it, so it is easy to identify. In addition, the aforementioned second plane 28 can also be set on the first component 291, and the second plane 28 and the aforementioned groove 2912 are located on both sides of the radial direction of the second component 292, so that the second plane 28 and the groove 2912 can together form a set of features, thereby further improving the speed and accuracy of the intermediate connector 20 being identified.

[0070] Example 3

[0071] like Figure 6 As shown, in this embodiment, a third plane 13 is provided on the auxiliary positioning member 10, and the signal reflection pattern 14 is located on the third plane 13, and the signal reflection pattern 14 is used to identify the normal direction of the third plane 13. In this embodiment, the signal reflection pattern 14 is set on the same plane, that is, the aforementioned third plane 13. By identifying and processing the reflected signal of the signal reflection pattern 14, the normal direction and position of the plane where the signal reflection pattern 14 is located can be obtained. After the auxiliary positioning member 10 is manufactured, the third plane 13 has a definite spatial position relationship with the rest of the auxiliary positioning member 10, so the position and posture of the auxiliary positioning member 10 in three-dimensional space are obtained by identifying the normal direction and position of the third plane 13 obtained by the signal reflection pattern 14.

[0072] like Figure 5 As shown, as an optional but advantageous implementation, in this embodiment, the signal reflection pattern 14 includes a circular ring pattern 15 having a missing portion at a preset position.

[0073] In order to improve the accuracy and speed of identifying the position and posture of the auxiliary positioning member 10 in three-dimensional space according to the signal reflection pattern 14, the present embodiment uses the circular ring pattern 15 for auxiliary identification. In addition, the present embodiment also sets notches at certain preset positions of the circular ring pattern 15, and different positions of notches correspond to different information. For example, different positions of notches can correspond to different codes, and the codes can be used as the ID of the brand and / or model of the implant 30 measured by the auxiliary positioning member 10, so that the brand and / or model of the corresponding implant 30 can be found by identifying the circular ring pattern 15 with missing parts.

[0074] When a patient needs to have dental implants in multiple locations, since different brands and / or models of implants 30 are often suitable for different locations in the patient's mouth, in order to achieve the best implantation effect, in theory, the most suitable brand and / or model of implants 30 should be implanted in each implantation location, so that there will be implants 30 of different brands and / or models in the same patient's mouth. Since the structures of implants 30 of different brands and / or models are different, the existing technology cannot accurately identify the positions of all these implants 30 of different brands and / or models, causing the patient to have to give up the treatment plan of using the best implant 30.

[0075] In this embodiment, different codes corresponding to the positions of different notches in the circular pattern 15 can be used as the ID of the brand and / or model of the implant 30 measured by the auxiliary positioning member 10. In this way, the processing circuit can identify the ID reflecting the brand and / or model of the implant 30 while identifying the position of the auxiliary positioning member 10. The processing circuit can obtain the three-dimensional model data of the implant 30 detected by the detection device of this embodiment from the three-dimensional model database storing various brands and / or models of implants 30. After adopting the above method, accurate detection of the positions of implants 30 of different brands and / or models in the oral cavity of the same patient can be achieved.

[0076] In order to facilitate the design and installation of the crown part in the later stage, the present embodiment can also use a scanning device to scan the dental arch part in the patient's mouth with the intermediate connector 20 (the intermediate connector 20 is connected to the implant 30, and the auxiliary positioning member 10 is not connected to the intermediate connector 20) to obtain a virtual three-dimensional model of the dental arch including the intermediate connector 20 in the second reference coordinate system. After the posture detection device in the present embodiment detects the posture of the intermediate connector 20 and the implant 30 in the three-dimensional space, the processing circuit obtains the virtual three-dimensional model of the implant 30 and the intermediate connector 20, and places the aforementioned model in the virtual three-dimensional space under the first reference coordinate system according to the aforementioned detected posture. Finally, the virtual three-dimensional model of the dental arch including the intermediate connector 20 obtained by scanning and the virtual three-dimensional model of the implant 30 and the intermediate connector 20 in the virtual three-dimensional space obtained by the detection device in the present embodiment are aligned, so that the virtual three-dimensional model of the intermediate connector 20 and the virtual three-dimensional model of the dental arch are located in the same coordinate system, so that the position of the implant 30 equivalent to the dental arch can be accurately obtained. In the aforementioned registration process, the intermediate connecting member 20 in the first reference coordinate system and the intermediate connecting member 20 in the second reference system are mainly registered, so as to transform the virtual three-dimensional model of the dental arch into the first reference coordinate system.
