Natural Looking Esthetics

Provides a tooth-colored restoration.

With its tooth-colored shade and preformed anatomical shape, Protemp™ Crown Temporization Material provides a temporary restoration with natural-looking esthetics. The crowns can be customized and/or repaired using a conventional flowable such as Filtek™ Supreme Plus Flowable Restorative, or composite materials, and can be polished to a shiny tooth-like appearance.

Custom Fit

Protemp™ Crown provides a custom fit for your adult patients.  Protemp™ Crown temporization material can be trimmed, adapted and re-shaped chair-side using common dental instruments. The end result produces a good marginal, interproximal and occlusal fit which promotes gingival health and maintains temporary space while maintaining good provisional strength.

Very low Oxygen Inhibited Layer

Protemp™ Crown has very low oxygen inhibited layer and other physical characteristics such as no odor and low exothermic temperatures.  Because Protemp™ Crown is not a liquid powder mix, there is no unpleasant smell when working with the product.  And because it is light cured on demand there are low exothermic temperatures during the fitting process.

Initial comparison

"Making temporaries is now very convenient with no preliminary impression. This revolutionary new process is simple, quick and easy producing a temporary that fits well, is kind to the tissue, does not come off and keeps the occlusion in place. A definite winner for 3M ESPE!" -- Joseph A. Blaes, DDS

"This is a paradigm shift in temporization. Adjectives alone cannot convey the practical application of a product like this. It’s a total success for high-quality temporary restorations. When you get it in your hands, you will be amazed." -- Robert G. Ritter, DMD

"This is the greatest invention in temporization in decades. I haven’t seen anything this revolutionary since the ion polycarbonate crown." -- John Sorensen, DMD

"It comes in handy using it in places where I’d be stuck before. There are certain cases where I just know I wouldn’t truly be happy with the results using current products, but now I can take those cases and be extremely happy with the results because of this product innovation." -- Jeffrey B. Dalin, DDS

"I love the predictability of this product. I can see the margins inside the temporary, just like reading the impression. Then I just trim and polish to the margin for an exquisite provisional. It’s a fast process and the simplicity really helps save a lot of time." -- Don M. Erickson, DDS

"Other crowns would often break or fall off, but that doesn’t happen with this product. We no longer have patients coming back to the office because they are in pain or the crown cracked in half or got lost. It’s really a no-brainer." -- Julie George, RDA

What is Protemp Crown?

Protemp Crown is a light-cured methacrylate composite crown that is designed for temporary restoration of teeth prepared for full crowns. Initially, Protemp Crown’s self-supporting, malleable consistency makes it easy and fast to place, trim, fit, and customize.

The light-curable resin of Protemp Crown is composed of bisGMA, dimethacrylate polymer, and rheology modifiers. Silanated zirconia-silica and fumed silica fillers are used to impart physical strength, radiopacity, and wear resistance. The silanated inorganic filler loading is approximately 78% by weight; the average particle size of the filler is approximately 0.6 micrometers. Protemp Crown also contains pigments and a photoinitiator system.

What sizes and shapes will be available for Protemp Crown?

There are (9) Protemp Crown sizes: Molar, Bicuspid(Premolar), Cuspid(Canine)

  • Upper Small Molar
  • Upper Large Molar
  • Lower Small Molar
  • Lower Large Molar
  • Upper Small Bicuspid (Premolar)
  • Upper Large Bicuspid (Premolar)
  • Lower Bicuspid (Premolar)
  • Universal Small Cuspid (Canine)
  • Universal Large Cuspid (Canine)

Why are there only 9 sizes?

The anatomy of Protemp Crown is symmetric to allow for use in either right or left dentition. In addition, the crowns are malleable allowing for individual customizing and shaping. Subsequently, this reduces the number of crown shapes and sizes stocked in the dental office.

Is Protemp Crown be available for anterior dentition?

Protemp Crown for anterior teeth would complement the product line and will be considered at a later date. Use Protemp™ 3 Garant™ Temporization Material for your temporary anterior restorations.

What shade is Protemp Crown?

Protemp Crown is offered in one universal shade.

What is the reason for the clear film on the crown?

The film protects the crown during the manufacturing process and should be removed prior to placement.
