Proven effective - “Best Bonding Performance”

cmf is a trend-setting biocompatible adhesive system without TEGDMA, HEMA or other comonomers of low molecular weight. The system consists of cmf etch, cmf prime and cmf bond. It is a universal bonding system designed for direct application with any brand of composite.


In a recent study restorations completed in non-carious cervical lesions with cmf bond and els composite showed a 92% success rate after 5 years, and outperformed a traditional HEMA containing 2-step etch and rinse system. (1)

Characteristics

  • Light-curing enamel and dentin bonding agent
  • Prevention of postoperative sensitivity
  • Total-etch technique
  • Etches quickly, thoroughly and gently
  • No evaporation during its shelf-life



Advantages

  • 100% marginal integrity to enamel and dentin, even after thermocycling
  • High bond strength to enamel and dentin
  • Prevention of allergic reaction to HEMA and TEGDMA
  • Reliable sealing due to excellent wetting and penetration properties
  • Simultaneous enamel and dentin etching
  • Gentle on dentin and enamel due to its mild pH value
  • Risks of over drying and collapsing of the collagen fibres are reduced
