Porous structure design and properties of dental implants

AbstractAbstractAt present, selective laser melting (SLM) 3D printing technology can accurately control the internal pore structure and complex cell shape. Three types of reticulated meshes with cubic, G7 and composite structure cell shapes were fabricated by the SLM 3D printing technology using Ti–6Al–4V alloy powders. The bone stresses around the implant and the stresses in the implant were analyzed by ANSYS finite element software, which comprehensively evaluated the effect of porous dental implants with different spatial porosity characteristics on osseointegration. The results show that porous dental implants with composite structure of pore characteristics have improved mechanical and biological properties and can better promote the growth and integration of bone tissue.Keywords: Porosityfinite element analysisdental implantscell shapeelastic modulus Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by the Natural Science Foundation of Shanghai (No.19ZR1455100).
