Description

Technical Field

[0001] This application relates to the field of dental implant technology, and more particularly to an adjustable angle abutment and dental implant system. Background Technology

[0002] The dental implant abutment is a key component of a dental implant system. It connects the implant, which is inserted into the alveolar bone, to the crown restoration. Its main function is to transmit various forces, such as occlusal forces, to the implant and then distribute them to the surrounding alveolar bone. At the same time, it provides precise positioning and good retention for the crown restoration, ensuring that the restored tooth can perform normal chewing and aesthetic functions in the oral cavity.

[0003] Because the implant axis and the crown axis are not aligned, the abutment needs to be angled differently to accommodate the fabrication of the restorative components, thereby improving the overall mechanical properties and lifespan of the implant system.

[0004] However, existing bases have the problem that the angle is fixed at the factory and cannot be adjusted. Utility Model Content

[0005] In view of this, the purpose of this application is to propose an adjustable angle base that can adjust the base angle as needed according to the repair angle requirements.

[0006] To achieve the above objectives, this application provides a dental implant, the dental implant comprising:

[0007] A perforating abutment seat, wherein the perforating abutment seat has a first cavity;

[0008] A ball-head bolt, the ball-head bolt passing through the first cavity, the ball-head bolt including a ball head, a first connecting part and a second connecting part arranged sequentially along the axial direction, the first connecting part being disposed inside the first cavity, the second connecting part being disposed outside the first cavity for connection with a dental implant, and the ball head being disposed outside the first cavity;

[0009] The universal sleeve has a second cavity inside, and a first internal thread is provided in the second cavity. The ball head bolt is disposed in the second cavity and is adapted to the second cavity.

[0010] A locking bolt is disposed in the second cavity, and the locking bolt is provided with a first external thread that is screwed into the first internal thread;

[0011] The universal sleeve can rotate relative to the center of the ball head bolt to adjust the angle between the axial direction of the universal sleeve and the axial direction of the ball head bolt. The locking bolt can rotate under the action of the tightening device until it abuts against the ball head bolt and locks the universal sleeve and the ball head bolt.

[0012] In a preferred embodiment, a second internal thread is provided in the first cavity, and a second external thread matching the second internal thread is provided in the second connecting portion.

[0013] In a preferred embodiment, the abutment perforator further includes a positioning groove, which is disposed at one end of the first cavity, and the first connecting portion is provided with a positioning part adapted to the positioning groove, which is disposed within the positioning groove.

[0014] In a preferred embodiment, the positioning groove is arranged in an annular shape around the first cavity, and the positioning part is arranged in an annular shape around the ball head bolt.

[0015] In a preferred embodiment, the second cavity has a first opening at one end near the ball head bolt, and the diameter of the first opening is smaller than the diameter of the ball head bolt.

[0016] In a preferred embodiment, the inner wall of the second cavity near the first opening is configured as an arc surface.

[0017] In a preferred embodiment, the locking bolt is provided with a first connection structure for connecting to the tightening device.

[0018] In a preferred embodiment, the first connection structure includes an internal hexagonal groove.

[0019] In a preferred embodiment, the ball head is provided with a second connection structure for connecting to a tightening device.

[0020] Based on the same inventive concept, this application also provides a dental implant system, comprising:

[0023] The crown is connected to the universal sleeve.

[0024] As described above, the adjustable angle base provided in this application is connected to a universal joint via a ball head bolt. The universal joint can rotate relative to the center of the ball head bolt to adjust the angle between the axial direction of the universal joint and the axial direction of the ball head bolt. The locking bolt can rotate under the action of a tightening device until it abuts against the ball head bolt and locks the universal joint and the ball head bolt together, thereby locking the angle between the axial direction of the universal joint and the axial direction of the ball head bolt at the target angle. Therefore, the adjustable angle base in this application can adjust the base angle according to the repair angle requirements, reducing the amount of stock required, thereby reducing costs and repair difficulty.

[0025] Meanwhile, the base angle can be adjusted according to the angle of the repaired component, which can reduce the scrap rate of the repaired component. Attached Figure Description

[0046] Reference Figure 1-11 As shown, one embodiment of this application provides an adjustable angle base 100, which includes a base through-gum seat 1, a ball head bolt 2, a universal sleeve 3, and a locking bolt 4.

[0047] The abutment transgingival seat 1 has a first cavity 11; the ball head bolt 2 passes through the first cavity 11, and the ball head bolt 2 includes a ball head 21, a first connecting part 22 and a second connecting part 23 arranged sequentially along the axial direction. The first connecting part 22 is disposed in the first cavity 11, and the second connecting part 23 is disposed outside the first cavity 11 for connection with the dental implant. The ball head 21 is disposed outside the first cavity 11; the universal sleeve 3 has a second cavity 31, and the second cavity 31 is provided with a first internal thread 311. The ball head bolt 2 is disposed in the second cavity 31 and is adapted to the second cavity 31; the locking bolt 4 is disposed in the second cavity 31, and the locking bolt 4 is provided with a first external thread 41 that is screwed into the first internal thread 311.

[0048] The universal sleeve 3 can rotate relative to the ball center of the ball head bolt 2 to adjust the angle between the axial direction of the universal sleeve 3 and the axial direction of the ball head bolt 2. The locking bolt 4 can rotate under the action of the tightening device until it abuts against the ball head bolt 2 and locks the universal sleeve 3 and the ball head bolt 2.

[0049] This application provides an adjustable angle base 100, which is connected to a universal joint 3 via a ball head bolt 2. The universal joint 3 can rotate relative to the center of the ball head bolt 2 to adjust the angle between the axial direction of the universal joint 3 and the axial direction of the ball head bolt 2. A locking bolt 4 can rotate under the action of a tightening device until it abuts against the ball head bolt 2, locking the universal joint 3 and the ball head bolt 2 together, thereby locking the angle between the axial direction of the universal joint 3 and the axial direction of the ball head bolt 2 at the target angle. Therefore, the adjustable angle base 100 of this application can adjust the base angle according to the repair angle requirements, reducing the amount of stock required, thereby reducing costs and repair difficulty.

[0050] Meanwhile, the base angle can be adjusted according to the angle of the repaired component, which can reduce the scrap rate of the repaired component.

[0051] Specifically, refer to Figure 2 As shown, the angle between the axial direction of the universal sleeve 3 and the axial direction of the ball head bolt 2 is β. Preferably, β = 0°-30°, such as 0°, 10°, 15°, 17°, 20°, 15°, 30°, etc. In other embodiments, β can also be greater than 30°, such as 35°, 40°, 45°, etc., and there is no specific limitation.

[0052] Reference Figure 4 and 5As shown, in one embodiment, a second internal thread 111 is provided in the first cavity 11, and a second connecting part 23 is provided with a second external thread 231 that matches the second internal thread 111. When the ball head bolt 2 is assembled with the abutment transgingival seat 1, the ball head bolt 2 enters the first cavity 11 from one end of the first cavity 11 and rotates relative to it until the second external thread 231 and the second internal thread 111 are threadedly engaged. Then it continues to rotate until the second external thread 231 disengages from the second internal thread 111, and the second connecting part 23 can then be placed outside the first cavity 11 for connection with the dental implant.

[0053] To ensure the smooth passage of the second connecting part 23 through the first cavity 11, the minimum inner diameter of the first cavity 11 needs to be greater than the maximum outer diameter of the second connecting part 23. Since the maximum outer diameter of the second connecting part 23 is greater than the outer diameter of the first connecting part 22, the provision of the second internal thread 111 reduces the gap between the area of ​​the second internal thread 111 and the first connecting part 22, enhancing structural stability. Simultaneously, the abutment transgingival seat 1 can undergo axial displacement relative to the ball head bolt 2, facilitating the clamping of the abutment transgingival seat 1 when the ball head bolt 2 is connected to the dental implant, thus enhancing structural strength and stability.

[0054] Please continue to refer to Figure 4 and 5 As shown, in one embodiment, the abutment transgingival seat 1 further includes a positioning groove 12, which is disposed at one end of the first cavity 11. The first connecting portion 22 is provided with a positioning part 222 adapted to the positioning groove 12, and the positioning part 222 is disposed within the positioning groove 12. After the second connecting portion 23 is connected to the dental implant, the positioning part 222 and the positioning groove 12 fit tightly together, preventing radial relative displacement between the abutment transgingival seat 1 and the ball head bolt 2, thus ensuring structural stability.

[0055] Furthermore, the positioning groove 12 is arranged in a ring around the first cavity 11, and the positioning part 222 is arranged in a ring around the circumference of the ball head bolt 2 to further ensure structural stability.

[0056] Reference Figure 6 As shown, in one embodiment, the ball head 21 is provided with a second connecting structure 211 for connecting with a tightening device. The tightening device can be connected to the ball head 21 through the second connecting structure 211 and tighten the ball head bolt 2. Optionally, the second connecting structure 211 includes an internal hexagonal groove. In other embodiments, the second connecting structure 211 includes a slotted groove, a cross groove, etc., and the specific type is not limited.

[0057] Reference Figure 7 and 8As shown, in one embodiment, the second cavity 31 has a first opening 312 at one end near the ball head bolt 2. The diameter of the first opening 312 is smaller than the diameter of the ball head bolt 2 to prevent the ball head bolt 2 from detaching from the first opening 312. When the ball head bolt 2 is assembled with the universal sleeve 3, the second connecting part 23 of the ball head bolt 2 enters the second cavity 31 from the other end of the second cavity 31 away from the first opening 312.

[0058] Furthermore, the inner wall of the second cavity 31 near the first opening 312 is set as an arc surface 313. The arc surface 313 fits with the surface of the ball head 21, which helps to increase the contact area and ensure the stability of the universal sleeve 3 after it is locked with the ball head bolt 2. At the same time, it reduces the wear of the base during angle adjustment.

[0059] Reference Figure 9-11 As shown, in one embodiment, the locking bolt 4 is provided with a first connecting structure 42 for connecting with a tightening device. The tightening device can be connected to the locking bolt 4 through the first connecting structure 42 and tighten the locking bolt 4. Optionally, the first connecting structure 42 includes an internal hexagonal groove. In other embodiments, the first connecting structure 42 includes a slotted groove, a Phillips head groove, etc., and the specific type is not limited.

[0060] In another embodiment of this application, a dental implant system is provided, comprising: an adjustable angle abutment 100 as described in any of the above embodiments, a dental implant and a dental crown, wherein the dental implant is connected to a ball head bolt 2 and the dental crown is connected to a universal sleeve 3.

[0061] This application provides a dental implant system comprising an adjustable-angle abutment 100 connected to a universal joint 3 via a ball head bolt 2. The universal joint 3 can rotate relative to the center of the ball head bolt 2 to adjust the angle between the axial direction of the universal joint 3 and the axial direction of the ball head bolt 2. A locking bolt 4 can rotate under the action of a tightening device until it abuts against the ball head bolt 2 and locks the universal joint 3 and the ball head bolt 2, thereby locking the angle between the axial direction of the universal joint 3 and the axial direction of the ball head bolt 2 at the target angle. Therefore, the adjustable-angle abutment 100 in this application can adjust the abutment angle according to the restoration angle requirements, reduce the stock quantity, and thus reduce costs and restoration difficulty.

[0062] Meanwhile, the base angle can be adjusted according to the angle of the repaired component, which can reduce the scrap rate of the repaired component.
