Porous structure design and properties of dental implants

At 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.

Comparison of structure and mechanical properties of implants produced by injection method

Purpose: The paper presents the possibility to improve the mechanical properties of dental implants produced of Ti6Al4V titanium alloy and possibility to use a new method to production those implants. The aim of the study was a comparison of properties of the feed materials, produced and commercial implants made of Ti6Al4V. Design/methodology/approach: The innovative injection methods was used. The comparison of microstructures and microhardness were carried out. Findings: It was shown that the use of new injection methods in the dental implant producing process effects on their structure and thus their mechanical properties. It has been observed that implants manufactured in comparison to commercial implants have a varied structure which is changing from the surface of the implant to its core. These changes are associated with a producing method that ensures very rapid heat dissipation from the surface of the manufacturing element. Research limitations/implications: During the production of the implants, problems have been encountered with keeping the alloy clean may occur. Practical implications: Injection method can be used as a method for commercial production of dental implants. Originality/value: The paper presents the results of microstructure and mechanical properties of dental implants – produced by new injection method.
