3D printed root bone implant with multi-section structure

Abstract

The invention discloses a 3D printed root bone implant with a multi-section structure. The implant comprises a dental crown and an implant body arranged at the bottom of the dental crown; a fixing groove is formed in the top of the implant body; an abutment is movably connected to the interior of the fixing groove; the top of the abutment sequentially penetrates through the fixing groove and the dental crown and extends into the dental crown; and a biological silica gel sheet is fixedly connected to the surface of the abutment and is positioned at the top of the implant body. The invention relates to the technical field of implants. According to the 3D printed root bone implant with the multi-section structure, the cutting and bone grasping capacity of the implant body can be effectively improved through the arrangement of multiple sections of threads, so that the fixing stability of the implant body is achieved; a nano-hydroxyapatite coating can be released at the root of the implant body through micropores, so that the ingrowth of bone tissues on the surface of the implant body is facilitated, and the osseointegration can be promoted; and meanwhile, a TiN nano coating has remarkable antibacterial performance, so that the generation of bacteria is effectively inhibited, and the combining capacity of connective tissues around the implant body in the oral cavity is also improved.

Description

technical field [0001] The invention relates to the technical field of implants, in particular to a 3D printed root bone implant with a multi-segment structure. Background technique [0002] Oral implants, also known as dental implants, are also called artificial tooth roots. They are surgically implanted into the upper and lower jaws of the missing teeth of the human body. After the surgical wound is healed, the dentures are installed on its upper part Device, dental implant consists of (1) body: the part where the implanted denture is implanted into human tissue, (2) neck and (3) foundation pile or abutment part, body: the implant is implanted in human tissue According to the implantation site, it is further divided into: A. implanted into the periosteum or B. implanted in the soft tissue, 2. neck: the part connecting the body and the foundation pile or abutment, 3. the foundation pile or foundation Platform: It is the part of the dental implant exposed outside the mucosa...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a 3D printed root bone implant with a multi-segment structure, which solves the problem of the stability of the implant due to its poor cutting and bone grasping performance after the existing implant is fixed. Decreased sex, prone to loosening, and at the same time, the bonding ability between the implant and the connective tissue around the oral cavity is weak, which easily leads to the adhesion of bacteria, which is not conducive to the follow-up recovery of patients
