Description

Technical Field

[0001] The utility model relates to the technical field of artificial dental implants, in particular to a combined denture implant structure. Background Art

[0002] With the improvement of people's living standards, the demand for oral health and beauty is becoming more and more important. As a common oral restoration method, dentures are widely used in patients with tooth loss. However, there are some problems in the traditional denture restoration method, such as unstable retention, low chewing efficiency, poor comfort, etc. To solve these problems, in recent years, the method of implant dentures has emerged. Implant dentures achieve a stable retention effect by implanting artificial tooth roots into the alveolar bone of patients and forming a firm bone bond with the alveolar bone. Implant dentures can not only improve chewing efficiency, but also provide better comfort and natural feeling. However, there are some deficiencies in the existing implant denture structures. Some implant denture structures are relatively complex and require multiple surgeries, increasing the pain and treatment time of patients. In addition, some implant denture structures have high requirements for the quality of the patient's alveolar bone and may not be suitable for some patients with poor alveolar bone quality. Therefore, it is necessary to develop a new type of combined denture implant structure that can solve the problems existing in the existing implant denture structures and provide better treatment effects and patient experiences.

[0003] After retrieval, a combined denture implant structure is disclosed in the publication number: CN219594848U, which includes a tooth body, a fixing bolt, a abutment and an implant. The abutment is installed on the implant, and the tooth body is fixed to the abutment through the fixing bolt. One of the tooth body and the abutment is provided with a convex ring portion, and the other of the tooth body and the abutment is provided with a concave ring portion. The convex ring portion and the concave ring portion are matched, and the tooth body and the abutment are relatively fixed through the convex ring portion and the concave ring portion. Therefore, through the above structure of the utility model, since the tooth body and the abutment are relatively fixed through the convex ring portion and the concave ring portion, in actual use, the tooth body can be fixed by the mutual engagement between the convex ring portion and the concave ring portion, effectively avoiding the offset of the tooth body relative to the implant during actual use. Although the effect of fixing the tooth body is achieved through the mutual engagement between the convex ring portion and the concave ring portion in this application, there is no mention of how to fix the abutment and the implant, resulting in the problem that the tooth body transmits the biting force to the implant through the abutment, causing loosening between the abutment and the implant. Summary of the Invention

[0004] To make up for the above deficiencies, the utility model provides a combined denture implant structure, aiming to improve the problem that in the prior art, there is no mention of how to fix the abutment and the implant, resulting in the problem that the tooth body transmits the biting force to the implant through the abutment, causing loosening between the abutment and the implant.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1-3The utility model provides an embodiment: a combined denture implant structure, including an implant 1, the implant 1 is slidably connected with a block 2, the upper surface of the block 2 is fixedly connected with a connecting disk 3, the upper surface of the connecting disk 3 is fixedly connected with a conical block 4, the upper surface of the conical block 4 is fixedly connected with a connecting piece 5, the upper surface of the connecting piece 5 is fixedly connected with a base 6, the connecting piece 5 is slidably connected with a bolt 7, the outer wall of the bolt 7 is provided with an elastic gasket 8, the outer wall of the bolt 7 is threadedly connected with a sleeve 9, the outer wall of the sleeve 9 is slidably connected to the inside of the implant 1, the outer wall of the bolt 7 is threadedly connected to the inside of the conical block 4, the outer wall of the bolt 7 is threadedly connected to the inside of the connecting disk 3, the outer wall of the bolt 7 is threadedly connected to the inside of the block 2, and an implant component is provided inside the implant 1.

[0024] Specifically, screw the bolt 7 into the threaded hole of the connecting piece 5, then assemble the connecting piece 5 and the conical block 4 so that the bolt 7 passes through the two, and then install the connecting plate 3 on the top of the conical block 4 so that it fits tightly with the thread of the bolt 7. At this time, the connecting piece 5, the conical block 4, and the connecting plate 3 have formed a whole. Next, connect this whole with the block 2, insert the block 2 into the groove at the upper end of the implant 1, so that it fits tightly with the connecting piece 5, the conical block 4, and the connecting plate 3. This step is crucial because the block 2 will assume the role of stabilizing the connection. Finally, turn the bolt 7 so that its end is screwed into the sleeve 9, and the sleeve 9 engages with the bolt 7 to further enhance the stability of the connection. At this time, the work of connecting the base 6 and the implant 1 has been completed, and the entire connection system will exert its strong bearing capacity and stability.

[0025] Reference Figure 1 and Figure 4 The implant assembly includes an external thread 10, which is provided inside the implant body 1; a retaining hole 11 is provided inside the base 6, and the inner wall of the retaining hole 11 is bonded to the inside of the crown.

[0026] Specifically, the external thread 10 of the implant 1 is designed to have the following advantages: it can improve the bone tissue healing speed, and the increased contact area helps the bone tissue to wrap the implant 1 more quickly, forming a stable bone-bonding. This means that the patient's recovery speed after the operation will be accelerated, the pain and discomfort will be reduced, and the loosening risk will be decreased. The design of the external thread 10 increases the friction between the implant 1 and the bone tissue, thus reducing the possibility of loosening, which provides a more durable and stable treatment effect for the patient. It can improve the gum health. The larger contact area helps the gum to better adhere to the surface of the implant 1, reducing the risk of gum inflammation and bleeding, which helps to maintain the oral health of the patient and reduce the occurrence of periodontal diseases. It can simplify the surgical process. The design of the external thread 10 enables the implant 1 to be better fixed in the bone tissue, and the surgeon can more easily implant the implant 1 into the tooth socket. This not only reduces the surgical difficulty but also reduces the pain of the patient during the operation.

[0027] Refer to Figure 2 and Figure 3 , a telescopic rod 12 is fixedly connected to the lower surface of the sleeve 9, and the lower end of the telescopic rod 12 is fixedly connected to the inside of the implant 1; a spring 13 is sleeved on the outer wall of the telescopic rod 12, and the upper end of the spring 13 is fixedly connected to the lower surface of the sleeve 9; a slider 14 is fixedly connected to the outer wall of the sleeve 9, and the outer wall of the slider 14 is slidably connected to the inside of the implant 1; a guide rod 15 is slidably connected to the inside of the slider 14, and both ends of the guide rod 15 are fixedly connected to the inside of the implant 1; a suspension spring 16 is sleeved on the outer wall of the guide rod 15, the lower end of the suspension spring 16 is fixedly connected to the upper surface of the slider 14, and the upper end of the suspension spring 16 is fixedly connected to the inside of the implant 1.

[0028] Specifically, by compressing the telescopic rod 12 and the spring 13 downward through the sleeve 9, the buffering is realized and the tight meshing with the bolt 7 is maintained. This design not only improves the connection stability between the bolt 7 and the sleeve 9 but also reduces the impact of the vibration and shock generated during the chewing process on the teeth. While achieving a stable connection, the sleeve 9 also drives the slider 14 to slide downward. Through the limit design of the slider 14 by the guide rod 15 and the implant 1, the loosening phenomenon of the sleeve 9 caused by the rotation of the bolt 7 is avoided. In this way, the bolt 7 and the sleeve 9 can maintain a stable meshing state, greatly reducing the risk of possible failures during the tooth repair process. On the basis of ensuring the connection stability, the researchers also considered the stable placement of the dental crown on the abutment 6. By setting the retention hole 11 and the retention structure inside the dental crown, the tight fit between the dental crown and the abutment 6 is realized. In this way, even during the chewing process, the dental crown can always maintain a stable position, avoiding the offset phenomenon caused by uneven stress.

[0029] Working principle: When a combined denture implant structure is needed, first implant the implant 1 into the bone tissue on the patient's tooth bed. The external thread 10 increases the contact area between the implant 1 and the bone tissue, preventing loosening between the implant 1 and the bone tissue. At this time, screw the bolt 7 into the connecting piece 5, the conical block 4, the connecting plate 3, and the clamping block 2 in sequence. At this time, under the connection of the bolt 7, the connecting piece 5, the conical block 4, the connecting plate 3, and the clamping block 2 are closely fitted. Then insert the clamping block 2 into the card slot at the upper end of the implant 1. At this time, continue to turn the bolt 7, and the end of the bolt 7 is screwed into the sleeve 9 and meshes with the sleeve 9, thus achieving the effect of connecting the abutment 6 and the implant 1. When the sleeve 9 meshes with the bolt 7, it is subjected to the axial thrust of the bolt 7. Therefore, the sleeve 9 compresses the telescopic rod 12 and the spring 13 downward, and then buffers through the elastic force of the telescopic rod 12 and the spring 13 and maintains a tight mesh with the bolt 7. At the same time, the sleeve 9 drives the slider 14 to slide downward. The limit of the slider 14 by the guide rod 15 and the implant 1 prevents the sleeve 9 from rotating with the bolt 7, thus ensuring the stable meshing of the bolt 7 and the sleeve 9. At this time, bond the dental crown to the abutment 6, and through the mutual cooperation of the retention hole 11 and the retention structure inside the dental crown, the stable position of the dental crown on the abutment 6 is ensured, and the dental crown can be prevented from shifting during chewing.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
