Description

Technical Field

[0001] The utility model relates to the technical field of oral implant restoration, in particular to a base platform for occlusal recording of oral implant restoration. Background Art

[0002] The abutment is the intermediate structure connecting the implant and the upper restoration, and plays a key role in the occlusal record of oral implant restoration. It can evenly transfer the bite force generated during chewing from the upper restoration to the implant, thereby ensuring the stability of the implant and the long-term use effect. For example, when the patient chews harder food, the abutment can effectively disperse the force and reduce local excessive pressure on the implant.

[0003] At present, most of the abutments used in oral implants are connected to the implants through threads. There is a tiny gap between the implant and the abutment, which is prone to bacterial leakage, allowing microorganisms to penetrate and colonize inside the implant, which can easily cause inflammation of the soft tissue around the implant.

[0004] The existing patent (publication number: CN216985216U) discloses an abutment for oral implant restoration bite record, including an implant, an abutment inserted in the implant, and a sealing mechanism arranged between the abutment and the implant. The abutment for oral implant restoration bite record has a reverse screw tooth on the outer side of the implant for threaded installation and fixing of the implant in the alveolar bone. A sealing mechanism is arranged at the connection between the implant and the abutment, and a positioning mechanism is arranged at the same time to make the sealing mechanism fit tightly between the implant and the abutment, thereby achieving the purpose of sealing, preventing bacteria from entering the implant from the gap at the connection between the implant and the abutment, and preventing inflammation of the soft tissue around the implant.

[0005] In view of the above problems, existing patents have provided solutions. However, the existing abutments used for oral implant restoration occlusal records are prone to loosening during use, which may cause the position of the restoration to change, destroy the normal occlusal relationship originally established, and reduce chewing efficiency. Patients may experience chewing weakness and insufficient chewing of food. In addition, most abutments are connected to the implants by bolts without a sealing structure. Bacteria and foreign matter can easily invade the connection between the abutment and the implant, stimulate the surrounding soft tissues, and cause inflammatory reactions such as redness, swelling, and pain.

[0006] Therefore, an abutment for occlusal recording of oral implant restoration is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide an abutment for occlusal record in oral implant restoration, which can solve the problems that the existing abutment for occlusal record in oral implant restoration is prone to abutment loosening during use, resulting in the change of the position of the prosthesis, destroying the originally established normal occlusal relationship, reducing the chewing efficiency, and the patient may experience weak chewing and insufficient food chewing. Moreover, most abutments are connected to the implant through bolts without a sealing structure, and bacteria and foreign matters are likely to invade the connection between the abutment and the implant, stimulating the surrounding soft tissues and causing inflammatory reactions such as swelling and pain.

[0015] Preferably, a twisting groove is provided on the inner wall of the reinforcing bolt, and a pulling groove is provided inside the sealing block.

[0016] Preferably, an external thread is provided on the surface of the implant.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By setting a sealing mechanism in this application, the sealing sleeve and the sealing block are tightly clamped with the inner wall of the base structure, forming a reliable barrier to prevent bacteria in the oral cavity from entering the interior of the implant through the connection, effectively preventing saliva and moisture in the oral environment from entering the interior of the base structure, reducing the possibility of corrosion of the internal metal components, and extending the service life of the base structure and the implant;
