Rationale of the novel glass compositions.

CODE	MAIN NETWORK FORMER	AIM
NCL1	SiO2	To develop a material with osteogenic properties, mainly determined by the presence of a high amount of silica.
NCL2	SiO2	To develop a load-bearing material with osteogenic properties and tailored degradation rate.
NCL3	B2O3	To develop a material with improved degradation rate and appropriate level of bioactivity as well as mechanical properties
NCL4	B2O3	To develop a material with tailored degradation rate and osteogenic effects.
NCL5	P2O5	To develop a resorbable glass with controlled degradation rate.
NCL6	P2O5	To develop a resorbable glass with controlled degradation rate, and improved mechanical strength
NCL7	SiO2	To develop a material with antibacterial properties, mainly determined by the presence of silver oxide, and a good level of bioactivity.
NCL8	SiO2	To develop a material with osteogenic properties and tailored degradation rate for non-load bearing applications.
