Description

Technical Field

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

[0002] Dental implants, also known as dental implants, are surgically inserted into the alveolar bone of the upper and lower jaws at the site of tooth loss. After the surgical wound heals, a prosthetic tooth is then installed on top. With the improvement of living standards, people's demand for dental restoration is increasing.

[0003] In current dental implant procedures, the implant is typically connected to the abutment using a central screw. Common abutments can be categorized into three types: snap-fit ​​abutments, ball cap abutments, and composite abutments. Among these, snap-fit ​​abutments, also known as snap-fit ​​abutments, are becoming increasingly popular due to their affordability and removability.

[0004] Reference Figure 1 As shown, clinically, during the implantation of implant 3 into alveolar bone 1, implant 3 may become misaligned due to poor bone quality in alveolar bone 1 or poor implantation skills by the dentist. Currently, most snap-fit ​​abutments 4 are straight snap-fit ​​abutments, referring to... Figure 2 As shown. When implant 3 becomes misaligned, the angle is usually corrected using the angle correction cap 5, as shown in the diagram. Figure 3 As shown, the current angle correction cap 5 is typically composed of multiple parts that snap together sequentially. The part connected to the clip abutment 4 is angled, and the occlusal force F on the angle correction cap 5 is vertical. Therefore, the angle correction cap 5 experiences uneven stress on both sides, making it prone to deformation, especially during large-angle restorations. This can lead to difficulties in installation, inability to securely fasten, displacement, and detachment. Furthermore, because the correction angle β of the angle correction cap 5 is limited, when the tilt angle of the implant 3 exceeds the maximum correction angle of the angle correction cap 5, it becomes impossible to use the angle correction cap 5 for angle correction, making it impossible to install the crown and ultimately resulting in restoration failure.

[0005] Therefore, it is necessary to propose a new dental implantation solution to address the aforementioned problems. Utility Model Content

[0006] In view of this, the purpose of this application is to propose a dental implant system that can achieve large-angle correction, is easy to install, and has a stable and robust structure.

[0007] For the purposes described above, this application provides a dental implant system comprising:

[0008] Implants;

[0009] The snap-fit ​​abutment includes an abutment body and a first snap-fit ​​member. The abutment body is connected to the implant, and the first snap-fit ​​member is connected to the abutment body. The end of the first snap-fit ​​member away from the abutment body is provided with a snap-fit ​​portion for snapping with the crown.

[0010] The implant has a first axis, and the snap-fit ​​part has a second axis, the first axis and the second axis intersect.

[0011] In a preferred embodiment, the dental implant system further includes the crown, the crown comprising:

[0012] The crown itself;

[0013] The second snap-fit ​​component has a snap-fit ​​groove that snaps into the snap-fit ​​part, and the second snap-fit ​​component has a third axis that is collinear with the second axis.

[0014] In a preferred embodiment, the second snap-fit ​​member has a first groove in its circumference, the first groove being filled with adhesive, and the crown body and the second snap-fit ​​member are bonded together by the adhesive.

[0015] In a preferred embodiment, the base body is provided with a third cavity, the inner wall of the third cavity is provided with a second internal thread, the first snap-fit ​​member is provided with a first connecting part, and the first connecting part is provided with a second external thread in the circumferential direction that is screwed into the second internal thread.

[0016] In a preferred embodiment, the first snap-fit ​​member has a first annular sealing surface at one end near the base body, the first annular sealing surface surrounds the first connecting portion, and the base body has a second annular sealing surface that abuts against the first annular sealing surface.

[0017] In a preferred embodiment, the abutment body has a protrusion at one end away from the implant, the first snap-fit ​​member has a recess at one end near the abutment body that matches the shape of the protrusion and accommodates the protrusion, the third cavity is disposed within the protrusion, and the first connecting portion is disposed within the recess.

[0018] In a preferred embodiment, the implant body is provided with a first cavity, the abutment body is further provided with a second cavity, and the dental implant system further includes a first connector, which is partially located in the first cavity and partially located in the second cavity, to connect the abutment body to the implant.

[0019] The second cavity has a fourth axis, the first connector has a fifth axis, and the first axis, the fourth axis, and the fifth axis are located on the same straight line.

[0020] In a preferred embodiment, the second cavity is provided with a first opening at the end away from the implant for the first connector to enter and exit, and the first snap-fit ​​seals the first opening.

[0021] In a preferred embodiment, the second cavity communicates with the third cavity and partially overlaps within the space.

[0022] In a preferred embodiment, the angle between the first axis and the second axis is greater than 0 degrees and less than or equal to 60 degrees.

[0023] As can be seen from the above, the dental implant system provided in this application can achieve angle correction without the need for an angle correction cap by intersecting the first axis of the implant with the second axis of the locking part. This avoids the problems of uneven force and deformation caused by the angle correction cap, making crown installation more convenient and the connection more secure and stable after installation.

[0024] Meanwhile, the angle between the first axis of the implant and the second axis of the locking part determines the correction angle, thus enabling large-angle correction. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0045] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] Reference Figure 4-6 As shown, one embodiment of this application provides a dental implant system, which includes an implant 3 and a snap-fit ​​abutment 4. The snap-fit ​​abutment 4 includes an abutment body 6 and a first snap-fit ​​member 7. The abutment body 6 is connected to the implant 3, and the first snap-fit ​​member 7 is connected to the abutment body 6. The end of the first snap-fit ​​member 7 away from the abutment body 6 is provided with a snap-fit ​​portion 71 for snapping with a dental crown.

[0047] The implant 3 has a first axis L1, the snap-fit ​​part 71 has a second axis L1, and the first axis L1 and the second axis L2 intersect.

[0048] This embodiment provides a dental implant system that achieves angle correction without the need for an angle correction cap 5 by intersecting the first axis L1 of the implant 3 with the second axis L2 of the locking part 71. This avoids the problems of uneven force and deformation caused by the angle correction cap 5, making crown installation more convenient and the connection more secure and stable after installation.

[0049] Meanwhile, the angle β between the first axis L1 of the implant 3 and the second axis L2 of the locking part 71 determines the correction angle, thus enabling large-angle correction.

[0050] Specifically, when the implant 3 is tilted, the angle between the first axis L1 of the implant 3 and the vertical direction is β, and the angle between the second axis L2 of the locking part 71 and the first axis L1 of the implant 3 is set to β. This allows the second axis L2 of the locking part 71 to be set to the vertical direction, ensuring that the forces on both sides of the locking part 71 are even during occlusion, thereby ensuring the firmness and stability of the crown and preventing it from falling off.

[0051] Furthermore, the implant 3 is provided with external threads to facilitate implantation into the alveolar bone 1.

[0052] After implantation, the first clasp 7 is partially covered by the gum, while the clasp portion 71 is exposed to facilitate crown attachment.

[0053] Optionally, the angle β between the first axis L1 and the second axis L2 is greater than 0 degrees and less than or equal to 60 degrees. For example, the angle β between the first axis L1 and the second axis L2 can be 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, etc., and there is no specific limitation. In another embodiment, the angle β between the first axis L1 and the second axis L2 can also be greater than 60 degrees, for example, 65 degrees, 70 degrees, etc.

[0054] In one embodiment, the dental implant 3 system further includes a crown, which includes a crown body and a second clasp 8, as shown in the figure. Figure 7 As shown, the second snap-fit ​​member 8 is provided with a snap-fit ​​groove 81 that snaps into the snap-fit ​​part 71. The second snap-fit ​​member 8 has a third axis L3, which is located on the same straight line as the second axis L2.

[0055] Optionally, the second clip 8 and the first clip 7 are interlocked, facilitating the removal, installation, and cleaning of the crown. Furthermore, the second clip 8 is made of plastic, providing excellent flexibility for easy interlocking.

[0056] Please continue to refer to Figure 7 As shown, the second retainer 8 has a first groove 82 in its circumferential direction. The first groove 82 is filled with adhesive. The crown body and the second retainer 8 are bonded together by the adhesive to ensure the stability of the connection between the crown body and the second retainer 8.

[0057] Optionally, the second connector 8 is an integrated structure, as shown in the reference. Figure 7 As shown. Or, it is a split structure composed of multiple sub-parts 83 connected sequentially, see reference. Figure 8 As shown. The integrated structure helps ensure structural strength and stability, while the modular structure facilitates adjustments for any minor deviations. For example, if the implant 3 tilts too much during patient use after implantation, the angle can be fine-tuned using the second snap-fit ​​component 8 of the modular structure, avoiding the need for reimplantation.

[0058] Reference Figure 9 and 10As shown, in one embodiment, a third cavity 61 is provided inside the base body 6. The inner wall of the third cavity 61 is provided with a second internal thread. The first snap-fit ​​member 7 is provided with a first connecting portion 72. The first connecting portion 72 is provided with a second external thread in the circumferential direction that is screwed into the second internal thread. During assembly, the first snap-fit ​​member 7 is connected to the base body 6 by screwing the first connecting portion 72 into the third cavity 61, which facilitates disassembly and assembly. In another embodiment, the third cavity 61 can be disposed inside the first snap-fit ​​member 7, and the first connecting portion 72 can be disposed on the base body 6, thereby achieving the connection between the first snap-fit ​​member 7 and the base body 6.

[0059] Please continue to refer to Figure 9 and 10 As shown, in one embodiment, the first snap-fit ​​member 7 has a first annular sealing surface 73 at one end near the base body 6. The first annular sealing surface 73 surrounds the first connecting portion 72, and the base body 6 has a second annular sealing surface 62 that abuts against the first annular sealing surface 73. The sealing effect is achieved when the first annular sealing surface 73 abuts against the second annular sealing surface 62.

[0060] Please continue to refer to Figure 9 and 10 As shown, in one embodiment, the end of the abutment body 6 away from the implant 3 has a protrusion 63, and the end of the first snap-fit ​​member 7 near the abutment body 6 has a recess 74 that matches the shape of the protrusion 63 and accommodates it. A third cavity 61 is disposed within the protrusion 63, and a first connecting portion 72 is disposed within the recess 74. The protrusion 63 and the recess 74 cooperate to facilitate the rapid positioning and assembly of the first snap-fit ​​member 7 and the abutment body 6. Furthermore, the recess 74 is arranged in a ring around the first connecting portion 72.

[0061] Please continue to refer to Figure 5 , 9 As shown in Figure 11, in one embodiment, the implant 3 has a first cavity 31, and the abutment body 6 has a second cavity 64. The dental implant 3 system also includes a first connector 9, which is partially located in the first cavity 31 and partially in the second cavity 64, to connect the abutment body 6 and the implant 3. The second cavity 64 has a fourth axis L4, and the first connector 9 has a fifth axis L5. The first axis L1, the fourth axis L4, and the fifth axis L5 are collinear to achieve precise angle correction. Specifically, the first connector 9 includes a bolt, and the first cavity 31 has an internal thread for screwing into the bolt.

[0062] Please continue to refer to Figure 9As shown, in one embodiment, the second cavity 64 has a first opening 65 at the end away from the implant 3 for the first connector 9 to enter and exit, and the first snap-fit ​​7 seals the first opening 65. Further, the second cavity 64 has a second opening 66 at the end away from the implant 3 for the first connector 9 to enter and exit. During assembly, the bolt enters the second cavity 64 through the first opening 65 and then enters the first cavity 31 through the second opening 66.

[0063] Furthermore, to prevent the bolt from falling out of the second opening 66, an anti-detachment part 67 is also provided inside the second cavity 64. The diameter of the anti-detachment part 67 is smaller than the diameter of the bolt head to prevent detachment and ensure the stability of the connection between the abutment body 6 and the implant 3. After the bolt connects the abutment body 6 and the implant 3, the first snap-fit ​​member 7 connects to the abutment body 6 and seals the first opening 65 to prevent liquid or food residue from entering the second cavity 64 through the first opening 65 and causing corrosion to the internal structure.

[0064] Please continue to refer to Figure 9 As shown, in one embodiment, the second cavity 64 and the third cavity 61 are connected and partially overlap in space, which can maximize space utilization and save material costs. Specifically, during assembly, the first connector 9 first enters the second cavity 64 through the first opening 65, and after connecting the base body 6 and the implant 3, the first snap-fit ​​7 connects to the base body 6. At this time, the first connecting portion 72 is partially located inside the second cavity 64. In other embodiments, the second cavity 64 and the third cavity 61 can also be independent and not connected to each other.
