Abstract
Purpose: Surface modification is important techniques in modern dental and orthopedic implants. This study was performed to try embedding of bioactive materials in porous Ti implants.
Methods: Porous Ti implant samples were fabricated by sintering of spherical Ti powders in a high vacuum furnace. It’s diameter and height were 4 and 20 . Embedding process was used to suction and vacuum chamber. Loading properties of porous Ti implants were evaluated by scanning electron microscope(SEM), confocal laser scanning microscope(CLSM), and UV-Vis-NIR spectrophotometer.
Results: Internal pore structure was formed fully open pore. Average pore size and porosity were 10.253 and 17.506%.
Conclusion: Porous Ti implant was fabricated successfully by sintering method. Particles are necking strongly each other and others portions were vacancy. This porous structure can be embedded to bioactive materials. Therefore bioactive materials will be able to embedding to porous Ti implants. Bioactive materials embedding in the porous Ti implant will induced new bone faster.
