Abstract

The invention relates to a multi-segment implant assembly and a preparation method thereof, including an implant, a personalized abutment and fixing bolts, and the implant includes the first implant segment, the second implant segment, the third implant segment and the implant transgingival segment , the second implant section is a porous section, the implant body is provided with a threaded counterbore, and the upper end of the implant is provided with an abutment interface; the personalized abutment includes the crown connection section, the abutment transgingival section and the implant connection section, personalized The middle part of the abutment is also provided with a stepped hole, and the threaded end of the fixing bolt is threadedly connected with the threaded counterbore. The implant component can be customized according to the actual modulus of the patient's alveolar bone. The porous segment structure can effectively increase the contact area between the dense bone and the implant, improve the fit with the dense bone, and continuously stimulate the dense bone. The problem of looseness after installing the firmware is solved, the bonding force with the alveolar bone after implantation is improved, and the bone fusion effect is good; the preparation method has fast molding speed and short manufacturing cycle, and can meet the actual needs of different patients.

Description

technical field

[0001] The invention relates to the technical field of biomedical engineering, in particular to a multi-segment implant component and a preparation method thereof. Background technique

[0002] Successful dental implant surgery can achieve the basic restoration of natural tooth function. The stability of the implant in the early stage of the artificial dental implant process and the firmness of the connection between the crown, abutment and the implant in the later stage are the key to the final success of the implant. The quality of dental implants and osseointegration is one of the factors for the success of dental implants, that is, the structure and elastic modulus of implants play an important role in osseointegration. Reasonable structure and matching elastic modulus can make the implant and alveolar bone tightly combined. However, there are two major disadvantages in the existing dental implants. The stress concentration point is on the interface bet...
