Problems solved by technology

At this time, the bone tissue around the implant will bear a low load state for a long time, which will cause the implant to loosen easily
Moreover, the surface of the implant is in a sealed shape, and the osteoblasts of the alveolar can only grow on the surface of the dental implant, resulting in poor osseointegration
In addition, the Young's modulus of the existing implants is fixed, and the mechanical and structural properties are poor

Abstract

The invention relates to a multi-section implant assembly and a manufacturing method thereof. The implant assembly comprises an implant, an individual abutment and a fixed bolt, wherein the implant comprises an implanted section I, an implanted section II, an implanted section III and an implant trans-gingival section; the implanted section II is a porous section; a threaded counter bore is arranged inside the implant body; an abutment interface is arranged at the upper end of the implant; the individual abutment comprises a crown connection section, an abutment trans-gingival section and an implant connection section; a stepped hole is additionally arranged in the middle of the individual abutment; and the threaded end of the fixed bolt is in threaded connection to the threaded counter bore. The implant assembly can be customized according to the actual modulus of alveolar bone of a patient; by virtue of the structure of the porous section, the contact area between the implant and compact bone is improved and a fitting property of the implant to the compact bone is improved, so that the compact bone is continuously stimulated, a problem of loosening after firmware is installed is solved and binding force of the implanted implant body with the alveolar bone is improved, and a bone infusion effect is good. The manufacturing method is high in forming speed and short in manufacturing cycle, and the manufacturing method is capable of meeting actual demands of various 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...
