MATRIX ALONE IS NOT STRONG ENOUGH TO
  SUPPORT OCCLUSAL LOAD AND CONTRACTS
   EXCESSIVELY DURING POLYMERIZATION,
THERFORE REINFORCING IT WITH CERTAIN KIND
OF MATERIALS USED PROVIDES THE MATERIAL
           ADEQUATE STRENGTH.

PARTICLE SIZE DISTRIBUTION
 TO INCREASE FILLER LOADING, IT IS
NECESSARY TO ADD FILLER IN A RANGE OF
PARTICLE SIZES.
 IF SINGLE SIZE IS USED SPACE WILL EXIST
BETWEEN THE PARTICLE.
 SMALL PARTICLE SIZE FILLERS THEN FILL
THESE SPACES.
REFRACTORY INDEX
 FOE ESTHETIC MATERIALS, SHOULD HAVE
TRANSLUCENCY SIMILAR TO THAT OF TOOTH.
 1.5


        AMOUNT OF FILLER ADDED
 AS FILLER CONTENT INCREASES, THE
FLUIDITY REDUCES.
 DEGREE OF FILLER ADDITION IS
REPRESENTED IN TERMS OF WT % AND VOL %.
 HIGHER FILLER CONTENT, LOWER WATER
SURFACE ROUGHNESS
 FILLER PARTICLES ARE GENERALLY HARDER
THAN THE MATRIX.
 DURING FINISHING SOME FILLER PARTICLES
MAY PROTRUDE FROM SURFACE.
 IF PARTICLE SIZE PROTRUDING IS SMALL,
THEN RESULTING SURFACE ROUGHNESS IS OF
LITTLE CONCERN.

Composite is any material that is composed of hard,
    pebble-like filler particles similar to sand or
 pebbles, surrounded by a hard matrix of a second
 material which binds the filler particles together. 
 The filler particles can be any coarseness varying
 from large rocks to microscopically fine powder.

PACKABLE COMPOSITES

 BASED ON PRIMM, WHERE THE FILLER CONTENT IS
INCREASED AND MATRIX CONENT REDUCED.
 THE NOVEL FILLERS USED INCREASED THE
FILLER SURFACE AREA THAT WOULD ABSORB MORE
MATRIX & THUS AVOID STICKINESS.
 THE FIRST FEW PACKABLE COMPOSITES USED
FUSED PARTICLE AGGLOMERATES, FIBROUS FILLER
ADDITINS AND BETTER FILLER PARTICLE PACKING
ARRANGEMENTS.
 ALL THIS WILL REDUCE THE VISCOELASTICITY OF
EXAMPLES

SOLITAIRE
 FILLER USED IS CRUSHED BARIUM
ALUMINOSILICATE .
 THESE PARTICLES ARE BONDED AT HIGH
TEMPERATURES, CREATING LARGE PARTICLES WITH
COARSE STRUCTURE.
 THE UNIQUE GEOMETRY OF THE FILLER
COMPONENT CREATES AN UNSET COMPOSITE WITH
PACKABLE BEHAVIOUR.
 THIS IS BECAUSE OF FRICTION CAUSED BY SLIDING
ALERT
 FILLER USED IS CRUSHED BARIUM
BOROALUMINOSILICATE + COLLOIDAL SILICA.
 THESE ARE CHOPPED MICROGLASS FILLER +
CONVENTIONAL HYBRID FILLERS.

NANOFILLERS
 0.005 – 0.01 UM.
 THAT IS BELOW THE WAVELENGTH FOR
VISIBLE LIGHT (0.02 – 2UM),
 AS THESE PARTICLES DO NOT INTERACT
WITH VISIBLE LIGHT THEY DO NOT PRODUCE
SCATTERING OR SIGNIFICANT ABSORPTION.
 THE FILLERS HERE ARE NON-SILICATE
BASED, AS THEY DO NOT AGGLOMERATE,
UNLIKE THE SISLICA BASED FILLERS.
Current resin-based filling materials shrink, leak,
and wear away. This process allows decay to develop,
The new nanofiller and liquid-crystal filling material
reduce leakage by preventing shrinkage and resisting wear.
     Before the cavity is filled with this resin, a new
  treatment is applied to the pulp chamber to encourage

  • 2. ₪ INTRODUCTION ₪ WHAT ARE FILLERS? ₪ PROPERTIES OF A FILLER ₪ FILLERS USED IN VARIOUS MATERIALS ₫ COMPOSITES ₫ CERAMICS ₫ AMALGAM ₫ DIRECT FILLING GOLD ₫ TEMPORARY CEMENTS ₫ INVESTMENT MATERIALS ₫ CASTING ALLOYS ₫ IMPRESSION MATERIALS ₫ ENDODONTICS ₪ REFERENCES ₪ CONCLUSION
  • 4. MATRIX ALONE IS NOT STRONG ENOUGH TO SUPPORT OCCLUSAL LOAD AND CONTRACTS EXCESSIVELY DURING POLYMERIZATION, THERFORE REINFORCING IT WITH CERTAIN KIND OF MATERIALS USED PROVIDES THE MATERIAL ADEQUATE STRENGTH.
  • 6. PARTICLE SIZE DISTRIBUTION  TO INCREASE FILLER LOADING, IT IS NECESSARY TO ADD FILLER IN A RANGE OF PARTICLE SIZES.  IF SINGLE SIZE IS USED SPACE WILL EXIST BETWEEN THE PARTICLE.  SMALL PARTICLE SIZE FILLERS THEN FILL THESE SPACES.
  • 7. REFRACTORY INDEX  FOE ESTHETIC MATERIALS, SHOULD HAVE TRANSLUCENCY SIMILAR TO THAT OF TOOTH.  1.5 AMOUNT OF FILLER ADDED  AS FILLER CONTENT INCREASES, THE FLUIDITY REDUCES.  DEGREE OF FILLER ADDITION IS REPRESENTED IN TERMS OF WT % AND VOL %.  HIGHER FILLER CONTENT, LOWER WATER
  • 8. SURFACE ROUGHNESS  FILLER PARTICLES ARE GENERALLY HARDER THAN THE MATRIX.  DURING FINISHING SOME FILLER PARTICLES MAY PROTRUDE FROM SURFACE.  IF PARTICLE SIZE PROTRUDING IS SMALL, THEN RESULTING SURFACE ROUGHNESS IS OF LITTLE CONCERN.
  • 9. RADIOPACITY  BARIUM  ZINC THESE ARE USED  BORON TO PRODUCE RADIOPACITY  ZIRCONIUM  YTTRIUM SURFACE AREA  SMALLER THE PARTICLE SIZE LARGER IS THE SURFACE AREA.
  • 11. Composite is any material that is composed of hard, pebble-like filler particles similar to sand or pebbles, surrounded by a hard matrix of a second material which binds the filler particles together.  The filler particles can be any coarseness varying from large rocks to microscopically fine powder. 
  • 12. CLASSIFICATION BASED ON FILLER PARTICLE SIZE MEGAFILL MACROFILL VERY LARGE 10-100 U m PARTICLE SIZE 0.5-2MM MIDIFILL 1-10 U M MINIFILL MICROFILL O.1 – 1 U M 0.1 – 0.01 U M

  • 14. BENIFITS  INCREASES HARDNESS.  INCREASES STRENGTH.  REDUCES WEAR OF MATERIAL.  REDUCES POLYMERIZATION SHRINKAGE.  REDUCES THERMAL EXPANSION & CONTRACTION.  IMPROVED WORKABILITY.  REDUCES WATERSORPTION.  REDUCES SOFTENING.  REDUCES STAINING.
  • 15. DISADVANTAGE  DIFFICULT TO FINISH & POLISH  HARDER THAN RESIN MATRIX, SO PROTRUDES ON SURFACE WHICH MAY ACT AS AREAS OF STRESS CONCENTRATION.  CAN ABRADE OPPOSING TOOTH.
  • 16. TYPE OF FILLERS  GROUND QUARZ  COLLOIDAL SILICA  GLASS OR CERAMIC CONTAINING HEAVY METALS alumina silicate borosilicate  PURE SILICA OCCURS AS CRISTOBALLITE TRIDYMITE QUARTZ
  • 17. QUARTZ  USED IN CONVENTIONAL COMPOSITES.  CHEMICALLY INERT.  VERY HARD.  DIFFICULT TO POLISH.  ABRADES OPPOSING TOOTH.  0.1 – 1.00 UM
  • 18. COLLOIDAL SILICA  MICROFILLER  0.04 UM OR LESS  ADDED IN SMALL AMOUNT AS THEY HAVE LARGE SURFACE AREA.  SIZE SMALLER THAN WAVELENGTH OF LIGHT, SO BETTER POLISHING.
  • 19. CERAMIC CONTAINING HEAVY METALS  PROVIDE RADIOPACITY.  BARIUM  ALUMINIUM  ZINC  YITTRIUM TRIFLOURIDE  YITTERBIUM TRIFLOURIDE  TRICALCIUM PHOSPHATE  RARELY USED, ZIRCONIUM PHOSPHATE ZIRCONIUM DIOXIDE STRONTIUM
  • 20. MACROFILLERS  FINELY GROUND AMORPHOUS SILICA OR QUARTZ.  AVERAGE SIZE 8 – 12 um.  PARTICLES AS LARGE AS 50 um MAY ASLO BE PRESENT.  FILLER LOADING IS 70 – 80 % BY WEIGHT 60 -70 % BY VOLUME ADVANTAGE  COMPRESSIVE STRENGTH IMPROVED OF COMPOSITE DUE TO TRANSFER OF STRESS FROM
  • 21.  REDUCES WATER SORPTION, POLYMERIZATION SHRINKAGE, THERMAL EXPANSION. DISADVANTAGE  ROUGH SURFACE DEVELOPS DURING ABRASIVE WEAR OF SOFT RESIN MATRIX.  EXPOSING MORE OF FILLER PARTICLE, THAT PROTRUDE FROM THE SURFACE.  ALSO LEAD TO DISCOLORATION.
  • 22. MICROFILLERS  0.04 um.  80 % BY WEIGHT.  60 % BY VOLUME.  PROBLEMS OF SURFACE ROUGHENING & LOW TRANSLUNENCY ASSOCIATED WITH MACROFILLED COMPOSITES ARE OVERCOME BY USE OF COLLOIDAL SILICA.
  • 23. ADVANTAGE  SMOOTH SURFACE.  INORGANIC FILLER PARTICLE SMALLER THAN ABRASIVES, SO SILICA REMOVED ALONG WITH RESIN, LEAVING SMOOTH, POLISHED SURFACE. DISADVANTAGE  REDUCES TENSILE STRENGTH.  INCREASES WATER SORPTION. 
  • 24. SMALL PARTICLE  0.5 – 3 um.  FILLERS ADDED ARE GROUND QUARTZ TO IMPROVE SUTFACE ROUGHNESS & RETAIN OR IMPROVE PYSICAL PROPERTIES OF TRADITIONAL COMPOSITES.  80 -90 % BY WEIGHT.  65 – 70 % BY VOLUME.
  • 25. ADVANTAGES  COMPRESSIVE STRENGTH EXCEED THAT OF TRADITIONAL COMPOSITES.  HIGH MODULUS OF ELASTICITY.  HIGH TENSILE STRENGTH.  SURFACE SMOOTHNESS IS ALMOST SIMILAR TO THAT ACHIEVED BY MICROFILLERS.  GREAT WEAR RESISTANCE, THUS CAN BE USED IN HIGH STRESS BEARING AREAS.
  • 26. HYBRID FILLERS  0.6 – 1.0 um.  DEVELOPED IN AN EFFORT TO OBTAIN EVEN BETTER SMOOTHNESS THAN THAT PROVIDED BY SMALL PARTICLE, WHILE STILL MAINTAINING THE PHYSICAL PROPERTIES.  COLLOIDAL SILICA & GROUND PARTICLES OF GLASSES CONTAINING HEAVY METAL .
  • 27. ADVANTAGES  SMALLER PARTICLE SIZE + GREATTER AMOUNT OF MICROFILLERS INCREASES SURFACE AREA THUS, OVERALL FILLER LOADING IS NOT AS HIGH AS SMALL PARTICLE. PROVIDING A SMOOTH &POLISHED SURFACE.  PHYSICAL & MECHANICAL PROPERTIES RANGE BETWEEN TRADITIONAL AND
  • 28. PACKABLE COMPOSITES  BASED ON PRIMM, WHERE THE FILLER CONTENT IS INCREASED AND MATRIX CONENT REDUCED.  THE NOVEL FILLERS USED INCREASED THE FILLER SURFACE AREA THAT WOULD ABSORB MORE MATRIX & THUS AVOID STICKINESS.  THE FIRST FEW PACKABLE COMPOSITES USED FUSED PARTICLE AGGLOMERATES, FIBROUS FILLER ADDITINS AND BETTER FILLER PARTICLE PACKING ARRANGEMENTS.  ALL THIS WILL REDUCE THE VISCOELASTICITY OF
  • 29. EXAMPLES SOLITAIRE  FILLER USED IS CRUSHED BARIUM ALUMINOSILICATE .  THESE PARTICLES ARE BONDED AT HIGH TEMPERATURES, CREATING LARGE PARTICLES WITH COARSE STRUCTURE.  THE UNIQUE GEOMETRY OF THE FILLER COMPONENT CREATES AN UNSET COMPOSITE WITH PACKABLE BEHAVIOUR.  THIS IS BECAUSE OF FRICTION CAUSED BY SLIDING
  • 30. ALERT  FILLER USED IS CRUSHED BARIUM BOROALUMINOSILICATE + COLLOIDAL SILICA.  THESE ARE CHOPPED MICROGLASS FILLER + CONVENTIONAL HYBRID FILLERS.  THE OVERALL CONSISTENCY IS SIMILAR TI THAT OF TRITURATED AMALGAM.
  • 31. SUREFIL  FILLER USED IS CRUSHED MIDIFILLER, MINIFILLER, MICROFILLER.  THESE FILLER PARTICLES ARE MADE OF BARIUMFLOURO ALUMINOSILICATE GLASS + SILICA.  THIS PERMITS HIGH PACKING DENITY AND AMALGAM LIKE PROPERTIES.
  • 32. FLOWABLE COMPOSITES  LOWER FILLER CONTENT THAN PACKABLE COMPOSITES.  0.04 – 1.00 UM.  20 -25 % LESS THAN TRADITIONAL COMPOSITES.  MECHANICAL PROPERTIES INFERIOR.  FILLER CONTENT WAS REDUCED TO LET THE MATERIAL FLOW READILY, SPREAD UNIFORMLY & INTIMATELY ADAPT TO CAVITY
  • 33. COMPOMERS  THESE MATERIALS CONTAIN FUNCTIONAL GROUP OF POLY ACRYLIC ACID + METHACRYLATE, FILLERS TO WHICH GLASS PARTICLES ARE ADDED.  THERE FILERS HAVE FLOURIDE RELEASE PROPERTY.  Eg. DYCRAT – CALCIUM FLOUROAMINO SILICATE GLASS - FINELY MILLED GLASS
  • 34. SMART COMPOSITES  THESE CONTAIN BARIUM, ALUMINIUM, FLOURIDE SILICATE GLASS FILLER WITH YTTERBIUM TRI FLOURIDE, SILICON DIOXIDE AND ALKALINE GLASS.  FILLER CONTENT 80% BY WEIGHT 60% BY VOLUME.  FLOURIDERELEASE IS LOWER THAN GLASS IONOMER BUT MORE THAN COMPOMERS.
  • 35. ORMOCERS  THESE ARE ORGANICALLY MODIFIED CERAMICS.  FILLER USED IS SILICON OXIDE.  THESE ARE MODIFIED BY ADDING FIBRE REINFORCED COMPOSITES POLYMERIZABLE SIDE CHAINS.  FILLER HERE ARE THE IMPREGNATED FIBERS.  GENERALLY 10-15 UM, CAN BE SUPPLIED AS, PARALLEL GLASS FIBERS WOVEN FIBERS
  • 36. NANOFILLERS  0.005 – 0.01 UM.  THAT IS BELOW THE WAVELENGTH FOR VISIBLE LIGHT (0.02 – 2UM),  AS THESE PARTICLES DO NOT INTERACT WITH VISIBLE LIGHT THEY DO NOT PRODUCE SCATTERING OR SIGNIFICANT ABSORPTION.  THE FILLERS HERE ARE NON-SILICATE BASED, AS THEY DO NOT AGGLOMERATE, UNLIKE THE SISLICA BASED FILLERS.
