GLUMA Comfort Bond – bonding agent Heraeus Kulzer

GLUMA Comfort Bond

Gluma Comfort Bond is a light curing, single component bonding agent for use incombination with adhesive restorations. Gluma Comfort Bond was developed forbonding composite, compomer and Polyglas resins to the tooth structure as well as for bonding amalgams and indirect restorations (e.g. porcelain). Gluma Comfort Bond primes and bonds in one step.

Gluma Comfort Bond is an ethanol based formulation of light-activated, adhesive resins. Prior to the application of Gluma Comfort Bond the tooth structure is conditioned with GLUMA*Etch 20 Gel.

Composition
Gluma Comfort Bond contains

  • Methacrylate
  • Ethanol
  • Photoinitiators
    GLUMA*Etch 20 Gel contains
  • 20 percent phosphoric acid

Indications
1. Bonding of direct composite, Polyglas and compomer restorations.
2. Bonding of fresh amalgam.
3. Bonding of indirect restorations: Porcelain, Polyglas and composite restorations (inlays, onlays, veneers, crowns).
4. Sealing hypersensitive areas of teeth.

Application
1. Bonding of direct composite, Polyglas and compomer restorations.

Preparation
• It is recommend to use rubber dam.
• Clean tooth with an oil-free polishing paste.
• Prepare cavity according to the regulations of adhesive filling therapy.
• Rinse with water and air dry.
• In case of deep cavities it is recommended to protect the dentin adjacent to the pulp with an adequate cavity lining (e.g. calcium hydroxide preparation and cavity lining of glass ionomeric cement). Take care that only the dentin adjacent to the pulp is covered. The remaining cavity area is spared for the bonding of Gluma Comfort Bond.

Conditioning
Total Etch Technique using GLUMA*Etch 20 Gel.
• Attach a disposable tip to the GLUMA*Etch 20 Gel syringe.
• Beginning with the enamel margins, apply GLUMA*Etch 20 gel to the entire cavity surface (including the dentin) and leave for 20 seconds.
• Rinse GLUMA*Etch 20 Gel thoroughly and remove excess moisture from the preparation with a gentle stream of air for 1 – 2 seconds. Do not dehydrate the dentin. The best bonding effect is obtained when Gluma Comfort Bond is applied to moist and shiny dentin. If you wish to visually verify that enamel etching has taken place and have dried the preparation in order to do so, the entire preparation surface must be re-moistened with water (e.g. a damp pellet) prior to application of Gluma Comfort Bond.

Application of Gluma Comfort Bond

• Apply Gluma Comfort Bond immediately after having removed the excess water.

• Dispense Gluma Comfort Bond into a well, soak the applicator tip or a soft disposable brush, and apply a copious amount to the entire cavity surface.

• Apply two additional coats of Gluma Comfort Bond and wait for 15 seconds.

• Gluma Comfort Bond contains ethanol. Use a gentle air blast to evaporate solvent and water. Solvent and water are evaporated proposly, if surface film stops moving during air blasting. If the whole cavity surface is not uniformly shiny after this step, apply additional coatsof Gluma Comfort Bond. Then continue as described above.

• Light cure Gluma Comfort Bond for 20 seconds with a standard lightcuring unit (e.g.Translux).

• Place restorative material in the cavity according to manufacturer’s instructions.
