APPLICATION

Design Information:

  • In the construction of bridges with one pontic, the connection cross-section between the crown and the ponitc must not be less than 9 mm2.
  • In the construction of bridges with two pontics, the connection cross-section between the crowns and the ponitcs must not be less than 12 mm2.
  • By selecting the respective fixation system according to the indication, the user has to decide case-by-case whether the PMMA material ensures sufficient chewing stability for the restoration.

Trimming:

  • Cross-cut carbide burs suitable for resin or suitable cutting discs should be used to rework and separate frameworks, crowns, bridges, denture bases (CORiTEC gum PMMA disc only) and bite splints form the blank.
  • Avoid excessive heat development during trimming and polishing. This prevents inaccurate fitting.

Veneering of PMMA frameworks, crowns & bridges:

  • Milled PMMA frameworks, crowns and bridges may be coated with conventional veneering materials. Materials based on MMA are preferred.
  • When veneering with composites the connection with the PMMA must always be made according to the respective manufacturer's specifications.

Restoration:

Constructions made from CORiTEC temp PMMA disc can be restored and supplemented at any time with all standard MMA-based cold-curing polymers. Prior conditioning curing of the surface is necessary, preferably with acrylate-based bonding agent.

General remarks:

  • Minimum wall thickness after polishing: 1 mm
  • Processing PMMA frameworks may generate dust which can lead to irritation of the eyes and airways. Therefore, always ensure that the extraction system on your milling machine and at the workplace is working properly and that you are using personal protective equipment.
  • Please also note the instructions for use.
