Embodiment Construction

[0026] Its preparation method comprises the following steps:

[0027] Step 1: Preparation of root material titanium alloy composite powder. The sintering ratio is 98%Ti+1.5%Zn+1.0%Mg+0.5%Ag (mass fraction) with an average particle size of 21.2μm Ti, 30μm Zn, 55-100μm Mg, Ag mixed nano powder in drying Dry in the box at 150°C for 11 hours, mechanically mix the above powder in a QM-3SP4J planetary ball mill for 24 hours, mix the powder evenly and dry it at 80°C for 1 hour to obtain metal powder;

[0028] Step 2: 3D printing model construction. The data obtained by scanning the scanned area with MIMICS software were separated and reconstructed to obtain a three-dimensional model of the tooth root and abutment area to be extracted. Use Magic software to digitally design the 3D model and adjust the printing parameters as the implant model to be printed;

[0029] Step 3: Laser 3D printing molding. Copy the data of the printed implant model to the 3D printer for printing, set the...

Abstract

Then invention discloses a method for preparing a personalized porous antibacterial dental root implant. The method is characterized in that a 3D printing technology is adopted, materials are preparedfrom titanium alloy composite powder, and the dental root implant with a porous structure at the dental root portion is prepared. By means of the method, elasticity modulus of the prepared porous dental root implant is low, so that the dental root and the position of the agomphosis jawbone are combined stably, healing periods of the implant and biological bone tissues are shortened, and the anti-infection ability is good.

Description

technical field [0001] The invention belongs to the field of biomedical materials, in particular to a preparation method of a personalized porous antibacterial tooth root implant. Background technique [0002] Oral implant surgery is a surgical procedure in which oral implants are implanted into the jawbone in the edentulous area, and artificial crowns are made on the implants to replace the missing natural teeth to exercise their physiological functions. [0003] Implants with standardized sizes in traditional forms are usually inconsistent with the shape of the extraction socket, which will cause a gap between the implant and bone tissue after immediate implant surgery, making it difficult to obtain good initial stability. After 3 to 4 months of tooth loss or extraction, the soft tissue and bone tissue in the edentulous area recover to a certain extent before performing implant surgery. The implant treatment process is relatively long and will cause secondary surgical trau...
