Product Details

PermaShade LC light cure veneer luting resin is used exclusively for cementing veneers. Its ergonomic contra-angle syringe makes luting more convenient than other delivery methods. With enduring color stability, and low shrinkage, PermaShade LC is ideal for creating a long-lasting, esthetic veneer smile.

  • Unsurpassed low shade shift1
  • Can be used for porcelain, zirconia, composite, and other indirect veneers
  • Available in four VITA®2 shade options: Translucent, Opaque White, A2, and B1
  • Ergonomic contra-angle delivery aids in precise placement to small, delicate veneers
  • Medium viscosity keeps veneer from drifting once seated
  • Upon curing, low shrinkage stress prevents strain on the veneer3

Indications for Use

PermaShade® LC

Technical Data

Enamelast Uptake Graph
*With Peak® Universal Bond.

​​​​​​

Low Shade Shift

​Independent university tests confirm PermaShade LC showed no perceptible shade shift after an accelerated age process.1 Light-cured resins tend to be more color stable due to the addition of non-aromatic aliphatic amines, which are resistant to oxidation. For PermaShade LC, ΔE shade shift is less than 3. (3 or higher is visible to the human eye.)

Contra-Angle Syringe

​Designed to give added precision and convenience, PermaShade LC's unique syringe gives both ergonomic comfort and is perfect for use with smaller veneers.

Low Shrinkage

​​​​
Enamelast Uptake Graph
Low shrinkage stress reduces strain on veneers at polymerization, minimizing the risk of post-cure breakage.3

Procedures

PermaShade LC Step by Step

– See Instructions for Use for complete instructions, warnings, and precautions.

  1. 1

    ​Clean preparation, rinse, and dry. (We recommend Consepsis® Scrub CHX antibacterial solution and STARbrush® intercoronal brush to clean, disinfect, and remove residual cement.) Verify prosthetic fit.

  2. 2

    ​Etch clean bonding surface of the veneer with Porcelain Etch for 90 seconds, rinse, and dry. Apply phosphoric acid (Ultra-Etch®) for five seconds to remove porcelain salts and debris formed by hydrofluoric acid etching. Rinse and air dry.

  3. 3

    ​Apply a puddle coat of Silane to inside surface of prosthesis for one minute, dry, and set prosthesis aside. Do not rinse.

  4. 4

    ​Apply Ultra-Etch etchant to enamel and/or dentin for 20 seconds. Rinse thoroughly for five seconds and leave damp.

  5. 5

    ​Apply a puddle coat of Peak® Universal Bond with the Inspiral® Brush tip. Gently agitate and coat surface for 10 seconds. Thin/dry for 10 seconds using full air pressure. Preparation should appear shiny.

  6. 6

    ​Light cure with VALO® LED curing light for 10 seconds.

  7. 7

    ​Express a thin layer of PermaShade LC onto the inside bonding surface of the veneer. Carefully position and seat the veneer using gentle pressure. Tack cure for two seconds to avoid shifting.

  8. 8

    Clean the excess cement from margins and light cure with VALO for 10 seconds.

Customer Reviews

FAQs

  • In what shades is PermaShade LC available?

    ​PermaShade LC is available in four VITA® shade options: Translucent, Opaque White, A2, and B1.

  • What is the viscosity of PermaShade LC?

    ​PermaShade LC has a medium viscosity.

  • How should PermaShade LC be stored?

    ​Refrigerate PermaShade LC when not in use. For optimal handling, bring PermaShade to room temperature at least 2 hours before cementation.

  • Can PermaShade LC be used to lute a crown?

    ​No. PermaShade LC is a light-cured material and a crown may be too opacious to allow for complete light curing through the prosthesis.

  • Approximately how many veneers can be cemented using one syringe of PermaShade LC?

    ​Depending on how liberal or sparing the clinician is, one syringe (.95g) can be used to lute between 17 to 21 veneers.
