[0001] This utility model relates to the field of oral medical technology, and in particular to an implant position measurement component and an implant position measurement device. Background Technology

[0002] Dental implantation involves surgically inserting an implant into the patient's alveolar bone. To ensure an accurate fit between the implant and the existing dentition, precise implant placement is crucial. The applicant proposes using an implant placement measuring device to determine this precise placement. This method requires connecting an auxiliary positioning device with a signal reflection pattern to the implant inserted into the alveolar bone.

[0003] However, because the external shape and connection interface of implant composite abutments from different brands and manufacturers are different, it is currently difficult for the same auxiliary positioning component to reliably connect with implant composite abutments produced by different brands and manufacturers. Utility Model Content

[0004] In view of this, the present invention provides an implant posture measurement component and an implant posture measurement device to solve the technical problem that existing auxiliary positioning components cannot be used for reliable connection of implant composite abutments from different brands and manufacturers.

[0005] The technical solution adopted in this utility model is:

[0006] In a first aspect, this utility model provides an implant pose measurement component, comprising:

[0007] An auxiliary positioning component includes a first part and a second part. The surface of the first part is provided with an identification pattern.

[0012] Preferably, the third concentric positioning structure includes a first frustum, wherein the diameter of the end of the first frustum facing the first connector is greater than the diameter of the end of the first frustum facing away from the first connector.

[0013] Preferably, the first positioning part is further provided with a first limiting surface, the first limiting surface is located on the side of the first cone-shaped surface facing the first connector, and the first limiting surface abuts against the end of the second part away from the first part.

[0014] Preferably, the first positioning part further includes a second frustum surface, the second frustum surface is located at the end of the first frustum surface away from the first connector, the diameter of the end of the second frustum surface facing the first connector is greater than the diameter of the end of the second frustum surface away from the first connector, and the diameter of the second frustum surface is smaller than the diameter of the end of the first frustum surface away from the first connector.

[0015] Preferably, the first concentric positioning structure is a first cavity with a frustum-shaped inner wall, and the second concentric positioning structure is a frustum-shaped inner wall, with the frustum-shaped inner wall of the second concentric positioning structure located in the first cavity.

[0016] Preferably, the end of the second connecting portion near the first connecting portion is a frustum-shaped surface.

[0017] Preferably, the first mounting cavity includes a cylindrical second cavity disposed at one end of the second portion away from the first portion.

The image acquisition device is used to acquire signals reflected by a marker pattern and process them to obtain image data. The data processing device is used to process the image data acquired by the image acquisition device.

[0019] Beneficial Effects: The implant pose measurement component and device of this utility model utilize the concentric positioning structure of the second mounting part of the first connector to cooperate with the first concentric positioning structure of the auxiliary positioning part, maintaining a concentric positional relationship between the first connector and the auxiliary positioning part. Furthermore, the first concentric connection structure of the first connector and the second concentric connection structure of the second connector are used to connect them, ensuring a concentric relative positional relationship between the first and second connectors after connection. This utility model also utilizes the third concentric positioning structure of the second connector to cooperate with the implant composite abutment, achieving positioning between the second connector and the implant composite abutment, thus maintaining a high degree of concentricity between the second portion of the auxiliary positioning part and the implant composite abutment. Moreover, since the first positioning part and the third connection part of the second connector can be customized to match the shape and interface of implant composite abutments from different brands and manufacturers, when connecting the auxiliary positioning part and the implant composite abutment, a second connector matching the shape and interface of the implant composite abutment to be connected can be selected as a common connection interface for both the auxiliary positioning part and the implant composite abutment. In this way, the same auxiliary positioning component can be flexibly connected to implant composite abutments from different brands and manufacturers, and can maintain a high degree of concentricity after connection, without the need to make auxiliary positioning components for each brand of implant composite abutment, thus significantly reducing costs.

[0030] Example 1:

[0031] like Figure 1 and Figure 2As shown, this embodiment provides an implant pose measurement component, which includes an auxiliary positioning component 10, a first connecting component 20, and a second connecting component 30. Implant pose refers to the position of a selected reference point on the implant in three-dimensional space and the orientation of the implant in three-dimensional space defined by its axial direction.

[0032] like Figure 3 As shown, the auxiliary positioning component 10 in this embodiment includes a first part 11 and a second part 12. The surface of the first part 11 is provided with an identification pattern. The second part 12 is connected to the first part 11. The second part is provided with a first mounting cavity 121. A first concentric positioning structure 1211 is provided in the first mounting cavity 121.

[0033] The first part 11, where the marking pattern is located, can have a planar structure. The marking pattern can be made of a material that reflects signals that can be detected by the relevant acquisition equipment. The reflected signals can be electromagnetic signals, optical signals, sound waves, etc., and there are no restrictions. For example, the marking pattern can be made of a material that reflects infrared light. The image acquisition equipment can acquire the signals reflected by the marking pattern and obtain the position and orientation of the marking pattern in three-dimensional space based on the acquired signals. Since the position and orientation of these marking patterns on the auxiliary positioning component 10 are fixed after the auxiliary positioning component 10 is manufactured, knowing the position and orientation of the markings in three-dimensional space also reveals the position and orientation of the auxiliary positioning component 10 in three-dimensional space.

[0034] The second part 12 in this embodiment is generally cylindrical, and its top is connected to the first part 11. The second part 12 is connected to the implant composite abutment through the second connector 30. In order to ensure that the position and orientation of the implant composite abutment can be accurately identified, the second part 12 and the implant composite abutment need to be concentric after connection, that is, the axis of the second part 12 coincides with the axis of the implant composite abutment.

[0035] like Figure 4 As shown, in this embodiment, the first connector 20 includes a first mounting portion 21, a second mounting portion 22 and a first connecting portion 23 arranged sequentially along the axial direction. The second mounting portion 22 is provided with a second concentric positioning structure, which cooperates with the first concentric positioning structure 1211. The first connecting portion 23 is provided with a first concentric connecting structure 231.

[0036] After assembly, the first connector 20 is located in the first mounting cavity 121 of the second section 12, thereby saving the overall space occupied by the implant composite abutment position measurement component. The second concentric positioning structure of the first connector 20, after engaging with the first concentric positioning structure 1211 of the second section 12, ensures that the first connector 20 and the second section 12 maintain a concentric positional relationship, i.e., the axis of the first connector 20 coincides with the axis of the second section 12. The first mounting section 21 is cylindrical, and correspondingly, the inner wall of the cavity 121 used to house the first mounting section 21 is also cylindrical.

[0037] like Figure 5 As shown, in this embodiment, the second connector 30 includes a second connecting part 31, a first positioning part 32 and a third connecting part 33 arranged sequentially along the axial direction. The second connecting part 31 is provided with a second concentric connecting structure 311. The first concentric connecting structure 231 is connected to the second concentric connecting structure 311. The first positioning part 32 is provided with a third concentric positioning structure. The third connecting part 33 is used to connect with the implant composite abutment.

[0038] The second connecting part 31 is connected to the first connecting part 23 of the first connecting member 20 via the second concentric connecting structure 311. The first concentric connecting structure 231 and the second concentric connecting structure 311, while achieving connection, ensure that the first connecting member 20 and the second connecting member 30 maintain a concentric positional relationship after connection. The third concentric positioning structure on the first positioning part 32, in conjunction with the positioning structure on the implant composite abutment, keeps the second connecting member 30 concentric. Since the second connecting member 30 and the first connecting member 20 are concentric with the two concentric connecting structures, and the first connecting member 20 and the second part 12 are concentric with the two concentric positioning structures, the second part 12 of the auxiliary positioning member 10 maintains good concentricity with the implant composite abutment; that is, the axis of the second part 12 of the auxiliary positioning member 10 coincides with the axis of the implant composite abutment. Thus, the position of the implant composite abutment 40 can be accurately obtained based on the position of the auxiliary positioning member 10.

[0039] In this embodiment, the first positioning part 32 and the third connecting part 33 of the second connector 30 can be matched with the shape and interface of implant composite abutments from different brands and manufacturers. Thus, when connecting the auxiliary positioning part 10 and the implant composite abutment 40, a second connector 30 matching the shape and interface of the implant composite abutment to be connected can be selected as the common connection interface for the auxiliary positioning part 10 and the implant composite abutment 40. This allows the same auxiliary positioning part 10 to be flexibly connected to implant composite abutments 40 from different brands and manufacturers, maintaining a high degree of concentricity after connection, without needing to manufacture an auxiliary positioning part 10 for each brand and manufacturer's implant composite abutment, thereby significantly reducing costs.

[0040] like Figure 6 As shown, in this embodiment, the first concentric connection structure 231 is a tapered thread provided on the outer surface of the first connection portion 23, the second connection portion 31 is provided with a first threaded hole 312, and the second concentric connection structure 311 is a tapered thread provided in the threaded hole.

[0041] During assembly, one end of the second connector 30 is inserted into the first mounting cavity 121 from below, and the first connector 20 is inserted into the first mounting cavity 121 from above. The portion of the first connecting part 23 with a tapered thread is connected to the threaded hole of the second connector 30 in the middle of the first mounting cavity 121, and the tapered thread in the threaded hole engages with the tapered thread in the threaded hole. This allows the first connector 20 and the second connector 30 to be connected to each other while maintaining a concentric position.

[0042] The outer surface of the third connecting part 33 is provided with a straight thread 331 for connecting with the implant composite abutment 40. The straight thread 331 on the outer surface of the third connecting part 33 matches the straight thread 331 on the implant composite abutment 40, thereby achieving a reliable connection between the second connecting part 30 and the implant composite abutment 40. The concentricity between the second connecting part 30 and the implant composite abutment 40 is achieved by a third concentric positioning structure.

[0043] In this embodiment, the third concentric positioning structure includes a first frustum surface 321, the diameter of the end of the first frustum surface 321 facing the first connector 20 is greater than the diameter of the end of the first frustum surface 321 facing away from the first connector 20.

[0044] In this embodiment, the third concentric positioning structure adopts the form of a frustum-shaped surface, corresponding to the frustum-shaped limiting hole on the implant composite abutment. The diameter of the end of the limiting hole facing the first connector 20 is greater than the diameter of the end of the limiting hole facing away from the first connector 20. The taper of the limiting hole is less than the taper of the third concentric positioning structure, so that the third concentric positioning structure can abut against the limiting hole. Because the diameter of the end of the first frustum-shaped surface 321 facing the first connector 20 is greater than the diameter of the end of the first frustum-shaped surface 321 facing away from the first connector 20, the front end of the first frustum-shaped surface 321 can be inserted into the limiting hole and abut against the inner wall of the limiting hole.

[0045] The first positioning part 32 is also provided with a first limiting surface 323. The first limiting surface 323 is located on the side of the first cone surface 321 facing the first connector 20. The first limiting surface 323 abuts against the end of the second part 12 away from the first part 11.

[0046] In this embodiment, the relative position between the second connector 30 and the second portion 12 in the axial direction is defined by the first limiting surface 323. The diameter of the first limiting surface 323 is larger than the diameter of the bottom of the first mounting cavity 121, thereby preventing the third concentric positioning structure of the second connector 30 from entering the mounting cavity of the second portion 12.

[0047] The first positioning part 32 further includes a second frustum surface 322, which is located at the end of the first frustum surface 321 away from the first connector 20. The diameter of the end of the second frustum surface 322 facing the first connector 20 is greater than the diameter of the end of the second frustum surface 322 away from the first connector 20, and the diameter of the second frustum surface 322 is smaller than the diameter of the end of the first frustum surface 321 away from the first connector 20.

[0048] In this embodiment, a second frustum surface 322 with a smaller radius is provided below the first frustum surface 321, so that the first positioning part 32 can be inserted into the limiting hole of the implant composite abutment, and the first frustum surface 321 can reliably abut against the inner wall of the first limiting hole.

[0049] In this embodiment, the first concentric positioning structure 1211 is a first cavity with a frustum-shaped inner wall, and the second concentric positioning structure is a frustum-shaped inner wall, with the frustum-shaped inner wall of the second concentric positioning structure located in the first cavity.

[0050] With the aforementioned structure, when the first connector 20 is placed into the first cavity, the frustum-shaped surface of the second concentric positioning structure abuts against the inner wall of the first cavity, thereby maintaining a concentric positional relationship between the first connector 20 and the second portion 12. In this embodiment, the end of the second connecting portion 31 closest to the first connecting portion 23 is a frustum-shaped surface to facilitate the connection between the first connecting portion 23 and the second connecting portion 31.

[0051] In this embodiment, the first mounting cavity 121 includes a cylindrical second cavity 1212 disposed at the end of the second portion 12 away from the first portion 11. The second connector 30 and the first connector 20 are connected in the second cavity 1212, which saves space and protects the connection part.

[0052] The end of the first connector 20 away from the second connector 30 is provided with an internal hexagonal groove, so that an external hexagonal tool can be inserted into the end of the first connector 20 to rotate the first connector 20.

[0053] In this embodiment, the marking pattern includes a central circle at the center and four positioning circles around the central circle. The four positioning circles are located at the four corners of the same square, the center of which coincides with the circle of the central circle. The marking pattern also includes a ring pattern with missing portions at predetermined positions. Furthermore, the marking pattern includes a closed frame formed by lines. The ring pattern, the central circle, and the positioning circles are located within the closed frame. Several protrusions extending towards the center of the marking pattern are provided inside the frame. This embodiment uses the number and width of the aforementioned protrusions to identify the number of the auxiliary positioning element 10, thereby enabling quick identification of the number of each auxiliary positioning element 10 when using multiple auxiliary positioning elements 10.
