Description

Technical Field

[0001] The utility model belongs to the technical field of dental implants, in particular to a split-type internal insertion type external connection conversion base. Background Art

[0002] Dental implants are an important method used in modern dentistry to repair missing teeth. They are mainly composed of dental implants and abutments. Dental implants are implanted in the alveolar bone at the site of missing teeth, similar to the root of a natural tooth, to support the main structure of the denture and can be integrated with the bone. When the dental implant is implanted in the alveolar bone, three months later, the implant and the bone form a bony structure, and the denture restoration is fixed on the abutment, and then the abutment is fixed in the dental implant as required. The different structural forms of the abutment and the way it is connected and fixed to the dental implant determine the flexibility and practicality of the implant denture after restoration, and directly affect the use value and lifespan of the implant denture. According to the structure and connection method of the abutment and dental implant, dental implants can be divided into two categories: externally connected dental implants and internally connected dental implants.

[0003] After searching, in the dental implant abutment assembly with the announcement number CN220025246U, the utility model discloses a dental implant abutment assembly, including an implant and an abutment body, the upper side of the implant is docked with the abutment body, and the implant and the abutment body are respectively penetrated by limiting rods on both sides, and the limiting rod is provided with an anti-loosening mechanism on the side close to the abutment body.

[0004] The above-mentioned dental implant abutment assembly rotates the first limit block so that the first limit block and the limit rod are restricted together, and then the second limit block is rotated in the opposite direction so that the second limit block and the limit rod are restricted together. When the first limit block is loosened, the second limit block prevents the first limit block from rotating and loosening, which can effectively prevent the threaded connection between the implant and the abutment body from loosening due to external force or vibration, thereby making the dental implant less likely to loosen. The clamping block is engaged with the clamping groove under the action of the limit spring, making it difficult for the abutment body to rotate when it is loose, thereby further preventing the dental implant from loosening. However, the dental implant abutment still has some problems in actual use:

[0005] When the above-mentioned dental implant assembly is in use, if the implant becomes loose or the abutment assembly is damaged and needs to be maintained, the snap-fit ​​connection method makes it difficult to separate the abutment assembly, which increases the difficulty of maintenance.

[0006] Therefore, in order to solve the above problems, a split-type internal plug-in external connection conversion base is proposed. Utility Model Content
