General Remarks for Working with Dentapreg™ PFM

  • Dental stone model is a good training tool for trials of  DentapregTM PFM
  • Avoid sharp edges and undercuts on the model
  • Before forming Dentapreg™ PFM strip on a model, always apply separation liquid or wax
  • Always use the widest clinically acceptable Dentapreg™ PFM strip
  • During forming and adaptation of the Dentapreg™ PFM strip advance slowly from one end to the other to allow for a good adaptation of the fibrous reinforcement and small flow of the resin to avoid defects and shape memory effect
  • In order to minimize potential damage to the fibers, it is recommended to use plastic instruments for dental filling composites
  • When preparing the strip (measuring, trimming), keep the strip in its original transparent protection foil to avoid contamination
  • Avoid sharp edges and extremely small interproximal curvatures when forming Dentapreg™ PFM strips to prevent fiber breakage
  • Most commercially available light or dual curing dental adhesives can be used to bond Dentapreg™ PFM strips
  • Adhere according to the acid etching and adhesive  procedures recommended by the manufacturer of the etching agents and adhesive
  • Polishing or sand blasting of cured Dentapreg™PFM should be avoided, to enhance patient comfort and maintain good hygienic conditions, a layer of light curing hybrid composite can be applied on the Dentapreg™PFM surface and polished with standard procedures
