Erformance of this bi-functional Ca-P coating. Conclusions Within this study, we’ve effectively integrated simvastatin and metronidazole 
into a Ca-P coating for titanium surface, and explored the pro-osteodifferentiation and antibacterial capabilities of this coating. We demonstrated the controlled release of each simvastatin and metronidazole from the coating, together with elevated osteogenic cell differentiation and also the inhibition of bacterial growth. Thinking of the safety, stability and low cost of Bi-Functionalization of Titanium Surface simvastatin and metronidazole, this bi-functional Ca-P coating approach represents a promising process to enhance the overall performance of metal implants or other bone substitute supplies, and can theoretically be effortlessly translated to clinical applications. On the other hand, further characterization of your bi-functional coatings described above is needed, as well as in vivo studies to appropriately assess the therapeutic potential of this technology.

Conclusions In this study, we’ve successfully integrated simvastatin and metronidazole into a Ca-P coating for titanium surface, and explored the pro-osteodifferentiation and antibacterial capabilities of this coating. We demonstrated the controlled release of both simvastatin and metronidazole in the coating, in conjunction with increased osteogenic cell differentiation along with the inhibition of bacterial growth. Taking into consideration the safety, stability and low price of Bi-Functionalization of Titanium Surface simvastatin and metronidazole, this bi-functional Ca-P coating approach represents a promising approach to improve the overall performance of metal implants or other bone substitute components, and may theoretically be easily translated to clinical applications. On the other hand, additional characterization of the bi-functional coatings described above is vital, as well as in vivo research to effectively assess the therapeutic prospective of this technology.
