Altering the filler component remains the most
significant development in the evolution of composite
resins. The addition of fillers in dental composites
provide dimensional stability, strength and reinforcement
to the soft resin matrix. Fillers of most commercial
dental composites include ground quartz, alumina silicate,
** pyrolytic silica **, lithium aluminum silicates, borosilicate
glass and other types of glass, some of which contain
oxides of heavy metals such as barium, strontium,
zinc, aluminum or zirconium (for radiopaque
characteristics).
