1. Properties Composite Resins By: Ahmed Al fawzan

3. Light gray when compared with dentin.

6. Classification of composites: Based on the filler particle size and distribution 1. Megafill very large fillers 2. Macrofill 10- 100 µm 3. Midfill 1- 10 µm 4. Minifill .1 – 1 µm 5. Microfill .01 - .1 µm 6. Nanofill .005 - .01 µm

7. Classification of composites: Based on method of polymerization 1. Self cure, autocure composites 2. Light cured composites a. UV light cured b. Visible light cured 3. Dual cured composites

9. particle size is ~ 8 – 12 µm

10. Filler – quartz, barium, strontium

11. Adv- good physical properties

12. Disadv - rough surface texture- increased wear - susceptible to discoloration

14. particle size – 1-5 µm

15. Filler- heavy metal glasses- lithium, barium, zirconium
