Adhesives, Cements and Intraoral Repair (last updated May 8, 2019)

ADHESIVE for direct bonding to enamel and dentin

Ultra-Etch 35% phosphoric acid (Ultradent) - Stocked

Optibond FL (Kerr)  - Stocked

  1. adhesiveApply 35% phosphoric acid to enamel first, and then to dentin making sure that the etchant remains on dentin for LESS than 15 seconds. Rinse thoroughly for 15 seconds. Completely remove excess moisture from operating field, then from preparation with cotton pellet, sponget or microbrush. Dentin surface should appear slightly moist.
  2. Apply Primer (#1) with microbrush for 30 sec with continuous gentle agitation. Replenish primer as needed.
  3. Initially air dry primer gently, and then finish with moderate air pressure to evaporate all solvents. The dried surface should present a shiny, evenly primed appearance.
  4. Apply Adhesive (#2) with an applicator brush or microbrush to spread evenly, removing excess to avoiding pooling or marginal buildup. Do not use air syringe to disperse adhesive.
  5. Light cure for 30 sec. (18 J)
  6. Apply resin-based composite.

Tooth Surface Treatment

  1. After isolating adjacent teeth (clear matrix strips) apply 35% phosphoric acid to enamel first, and then to dentin making sure that the etchant remains on dentin for LESS than 15 seconds. Rinse thoroughly for 15 seconds. Completely remove excess moisture from operating field, then from preparation with cotton pellet, sponget or microbrush. Dentin surface should appear slightly moist.
  2. Dispense ALL-Bond TE using the ACE dispenser into a dap pen dish, mix with an applicator for 5 sec.
  3. Again, protecting/isolating adjacent teeth (clean and dry clear matrix strips), apply 1-2 coats onto the entire tooth preparation with a light agitating motion for 5-10 seconds.
  4. Gently air dry until there is no visible movement of the material. Then dry thoroughly for a minimum of 10 sec. The surface should appear shiny; otherwise, apply additional coats of ALL-BOND TE and repeat.
  5. Light cure each surface for 10 sec at 500mW/cm2. (Optional when using Duo-Link from Bisco)
  6. Apply Duo-Link resin cement to the internal surface of the restoration directly from the syringe.
  7. Seat each restoration with gentle, passive pressure.
  8. Remove excess cement immediately with a brush or instrument.
  9. Light cure each surface of the restoration for 40 seconds
  10. Check occlusion.
  11. Clean up excess and polish margins if necessary with resin composites polishers. Porcelain surfaces should be adjusted and polished with ceramic polishers.
  12. Optional: Clean surface/margins and apply surface sealant and light cure

Luting and Resin Cements

Calibra (Dentsply/Caulk) – clinic approved, available in OPER

  • Base shades (3): translucent; opaque; light;
  • Catalyst (1): High viscosity
  • Description: light and dual-cured resin composite primarily used for cementation of resin composite or ceramic veneers, inlays/onlays
  • Directions for use: http://www.calibracement.com/sites/default/files/calibra-directions-for-use.pdf  Follow adhesive resin system instructions for bonding to tooth and Calibra instructions for luting the indirect restoration. If cementing veneer that is not excessively thick or opaque, use light cured base shade only. Simplifies luting procedure.


DUO-LINK (Bisco) – clinic approved, available in OPER

  • Description: DUO-LINK is a dual-cured luting cement with ultrafine filler particles and is intended to be used with an adhesive system. Available in a universal TRANSLUCENT shade, the exceptionally high glass filler content increases strength making DUO-LINK resistant to wear and staining. It is ideal for cementing all-ceramic/porcelain, metal, and composite restorations (inlays, onlays, crowns, bridges), as well as fiber and metal posts.
  • Instructions for use: See manufacturer’s instructions.
    • Working time: ≥ 2 min
    • Setting time: ≤ 5 min 30 sec
    • Light cure each surface of the restoration for 40 sec (24 J)
  • Directions for use: http://www.bisco.com/instructions/IN-027R7_English.pdf

luting agents

Panavia V5 (Kuraray) 

  • Description: Dual-cure, fluoride-releasing, esthetic, universal cement for silica-based ceramics, zirconia, composites and metals.
  • Indications: cementation of inlays, onlays, crowns, bridges, veneers, resin retained bridges, splints, implant restorations, post and cores and amalgam bonding.
  • Available shades: Universal A2, Clear, Brown A4, White, Opaque (opaque is self cure only)
  • Directions for use: ​http://kuraraydental.com/product/cements/panavia-v5

Porcelain etchant: Buffered hydrofluoric acid gel (Bisco)

clinic approved – available in OPER

  • Indications:acid gel
    • intraoral repair
    • preparing restorative material surface for luting
  • HF porcelain etchant improves the adhesive bond between porcelain and RBC/cement by increasing the surface area of the porcelain to be bonded.

Bis SILANE (Bisco)silane 

  • Description: BIS-SILANE is a two-part silane coupling agent that is used to enhance adhesion between porcelain and composite resins. Based on clinical experience, it has been noted that the silane, as packaged in the one-bottle systems, tends to polymerize as it approaches the end of its shelf life. The two-bottle silane system offers a more stable system to ensure effective bonding to porcelain. Silane is a dual function monomer consisting of a silanol group that reacts with the porcelain surface, and a methacrylate group that co-polymerizes with the resin matrix of the composite. Silane coupling agents are known to enhance the wettability of glass substrates by composite resins, increase physical, mechanical and chemical bonding of composite to porcelain, and yield a greater resistance to water attack at the bonding interface.
  • Prior to applying BIS-SILANE, the porcelain surface must be etched with buffered hydrofluoric acid. This process allows porcelain to become not only highly porous, but also highly receptive to the silane by creating reactive hydroxyl groups on the surface of the porcelain.
  • Directions for use:
    • Mix the BIS-SILANE by dispensing one drop from each of the two bottles (Parts A & B) into a mixing well and stir. Brush on 1-2 coats (thin coats are sufficient) of BIS-SILANE to the internal surface of the etched porcelain restoration and wait for 30 seconds. Dry with (warm if available) air syringe. NOTE: Surface of the porcelain will look the same after BIS-SILANE application to the naked eye.
    • Continue with cementation procedures.
