COMPOSITES IN DENTISTRY

  • Mid 1980s:Hybrid composites were developed.The first generation of Indirect lab processed microfil composite resin system was introduced.
  • 1987:Second generation of Lab processed resin was developed.
  • 1991:Mega filled composites with glass ceramic inserts coated with silane were introduced.
  • 1992:Introduction of  fiber-reinforced composites which were composed of woven glass or polythene fibers.

 

  • These are reinforcing particles or fibers that are dispersed in the matrix.
  • Filler particles are most commonly produced by grinding or milling quartz or glass to produce particles of varying sizes.
  • Various fillers used are:Colloidal silica,Glass fibers,lithium aluminium silicates,crystalline quartz,barium glass,microfine silica,sintered silica.
