Abstract：Because the collected 20 extracted premolars for orthodontic cone beam CT（CBCT）image information，using modeling software and 3D printers to produce a new bionic dental implant porous，bionic implant and premolars were divided into A and B two groups，by the universal flexural strength testing machine testing two groups. Statistical differences and flexural strength of two groups.
Key words：oral implant；3D printing technology；flexural strength
With the introduction of CBCT scanning technology and the rapid development of CAD/CAM technology，the application of 3D printing technology in oral implant has become more and more extensive in. so that it can achieve the uniform requirements of implant morphology and function，and make implant and natural dental organs better consistent with the biomechanical principle. The purpose of this study is to explore the feasibility and feasibility of 3D printing porous bionic dental implants，and to provide scientific basis for clinical application.
With the development of dental implant technology，the variety of the material and shape of the implant is increasing. At present，the dental implant system in commercial production has the geometric structure of columnar or cone. The customized implant can not only protect the hard and soft tissue，reduce the time of rehabilitation，but also achieve the uniform requirement of morphology and function，so as to make personalized bionic dental implant in the exercise function when the stress evenly spread to the surrounding bone tissue；on the other hand，the porous structure of the pore mutual connection，which provides conditions for the ingrowth of bone cells and fluid transport. Which is conducive to the stability of personalized bionic dental implant good. In this study，the use of 3D printing technology succeeded in making personalized porous bionic teeth are very similar with the goal of dental implant tooth shape，the neck to the apical surface of 1/3 with porous structure design，internal solid structure，set the 200μm pore size，a research shows that the growth of aperture 200-500μm more to bone cells，if the pore diameter is too small，can lead to cell blockage，hinder the formation of bone matrix and cell permeability，thickness as the beginning of each cross section of 1/5，pore thickness is appropriate，there is no unified results，also need to do related research.
