      (>10MPa)
    • Resin cement
      • High adhesive quality (18-20MPa)
      • ⇧ Retention
      • High hardness
      • Low solubility
      • All metal, ceramic,composite (indirect)
      • Occa. Post-op sensitivities
    • Adhesive quality
      • Non-adhesive (zinc phosphate)
      • Micromechanical bonding (resin cement)
      • Molecular adhesion (polycarboxylate,GI,RMGI)
    • Dental Cement
      • Zinc phosphate
      • Polycarboxylate
      • Glass ionomer

      • Resin cement
      Conventional Adhesive
    • Advantage conventional cement
      • Easy handling
      • Moisture tolerance
      • No pre-Tx steps
      • Routine for metal base
    • Advantage resin cement
      • Excellent mechanical properties
      • High bond strength with pre-Tx step
      • High aesthetics/translucency
      • Suitable for Ceramic, Porcelain, Composite,Metal
    • Resin cement
      • Matrix
      • Primer
      • Filler
      • Coupling agent
    • Resin cement
      • Matrix - Dimethacrylate
      • Primer- Dicrylate
      • Filler - Quartz, silica
      • Coupling agent- Silane dimethacrylate
      • Total etch Rely X ARC , Variolink II ,Calibra ,C&B
      • Self-etch Panavia F
      • Self-Adhesive Rely X Unicem
      Resin cement
    • Adhesion
      • Dentin/enamel (micromachanical bond)
      • Porcelain (hydrofluoric acid,Ammoniumfluoride acid)+ silane

      • Dentin/enamel (micromachanical bond)
      • Porcelain (hydrofluoric acid,Ammoniumfluoride acid)+ silane
      • Metal (sandblasting)(metal bonding adhesive)
      • Fiber post
    • Why are fiber post?
      • Clinical success rate: Less root fracture than with metal posts: Dentine-like flexural strenght avoids the “wedge” effect of stiff and hard metal posts.
      metal fiber post
      • Esthetics : the new post is translucent and does not shine through ceramic or composite restorations
      • 3. Easy and conservative removal with drills if endodontic re-treatment is required
      further advantages : no corrosion, easy cutting of over-length, light-translucent... root fracture! no local peak forces, no root fracture
    • Resin cement
      • Bond strength > Zinc phosphate 10 times
      • ↑ Retention
      • Reinforced ceramic - base Crown
      • Adhesive system (micromachanical bond-tooth)
      • (chemical bond-porcelain,metal)
      • Low solubility
      • ↓ leakage
    • Pre-treatment procedure
    • Pre-treatment procedure
    • Pre-treatment procedure

      • Dual cure
    • Adhesion
      • Dentin/enamel (micromachanical bond)

      • Fiber post
      Adhesive cement bonding to tooth ,alloy structure
      • Anesthetic
      • Isolate (pack cord)
      • Light cure 2-3 sec
      • Include 3-5 shades,silane
      • Remove solvent- can inhibit setting of resin cement
      • Excess bonding – poor fit,low strength
      • Temp NE
      Clinical Tips
    • Shade
      • Opaque – veneer + Tetracycline
      • Clear (translucent)
      • Vita shade
