Beskrivning

Steady & long-lasting – perfect!

Long-term temporaries with up to 3 years of wear!
Perfect color match to the pritidenta shades and the VITA classical shades*
Excellent processing during milling and polishing
Bending strength: > 96 MPa
Biocompatible: high degree of polymerization due to patented, industrial process

Indications:

Long-term temporary crown and bridge restorations (up to 3 years) in the
anterior and posterior region with up to 2 pontics
Splints for therapeutic restorations for temporomandibular joint problems
and functional diagnostics
Temporary anterior veneers for esthetic shape corrections

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 can be built-up with conventional veneering materials. Materials based on MMA are preferred.
  • When veneering with composites, please follow the respective manufacturer’s instructions.

Restoration:

Restorations made from CORiTEC temp PMMA disc can be restored and enhanced at any time with all standard MMA-based cold-curing polymers. The surface must first be conditioned, preferably with an acrylate-based bonding agent.

General remarks:

  • Minimum wall thickness after polishing: 1 mm
