Abstract

Fabrication and Investigation of Commercial Pure Titanium/Bioactive Glass Ceramic as a Material for Dental Implant

Author(s):Ghazwan Al-Kinani and Raghdaa K Jassim

Background: The osseointegration is a major factor influencing the success of the dental implant. The optimum circumstances of the osseointegration are the biointegration which means there is an intimate contact between bones and implant material without intervening space. The study aims at the fabrication of functionally graded material from bioglass at the surface and commercially pure titanium as a core of cylindrical implant specimen. Material and method: The functionally graded materials were fabricated, by using powder metallurgy method from bioglass 45S5 as a surface layer of the cylindrical specimen and commercially pure titanium as the core of cylindrical specimen. The compacted specimens were divided into three groups according to sintering temperature 800ºC, 900ºC and 1000ºC, with 3 hours holding time. The specimens of each group were analyzed by using scanning electron microscope and the energy dispersive X-ray spectroscopy. The porosity percentage was calculated and then mechanical evaluations were done by using Vickers hardness test and compressive strength test. Results: The scanning electron microscope examination shows a fusion of powder particles with an increase in the sintering temperature and decreases in the pores size among particles. And, also shows the diffusion of commercially pure titanium towards the bioglass at the interface at micrometric scale 100μm, 50 μm, and 10 μm. The results of energy dispersive X-ray spectroscopy also revealed that diffusion of commercially pure titanium towards bioglass at interface increased with an increase in the sintering temperature. Conclusion: Powder metallurgy method is used to obtain the synthetic functionally graded materials as implant material with the diffusion of the CPTi to the Bioglass at the interface.
