Simulated body fluid related to implant bioactivity: An in vitro study on dental implants
摘要
Abstract
Objective: To determine whether simulated body fluid (SBF) is suitable to estimate surface bioactivity of dental implants or not. Method: Two types of commercial dental implants (Osseolite()and NanoTiteTM with the aame macro-topography were investigated on apatite formation in vitro by soaking separately with SBF and DMEM for 14 days. The results were studied by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Result: No apatite formation was detected on all samples after soaking in SBF. But globular, uniform apatite-like mineral deposits, accompany with organic molecular attachment was detected on the NanoTite,surface by soaking it in DMEM. Conclusion:SBF does not appear to be suitable to estimate surface bioactivity of a material,but DMEM shows potential for immersion test, aa the influence of organic molecular on the apatite formation.关键词
