E.T.C.™ Easy Temporary Cement

SKU: S255
  • Strong adhesion to temporary prostheses.
  • Low viscosity allows complete seating of temporaries.
  • Translucent shade blends well with crown and tooth margins.
  • Automix syringe and dual-cure capabilities reduce chairside time
  • Eugenol free.
  • (1) 5ml automix syringe
  • (10) mixing tips.
Resin-based dual-cure E.T.C. is reliably strong and incredibly simple. All you have to do is express E.T.C. from the automix syringe right into the crown and seat it. If you’re using Parkell’s Brush&Bond® to protect the prep from sensitivity and recurring caries, just apply a thin layer of lubricant (e.g., Vaseline® or K-Y® Jelly) to the majority of the coronal portion of your crown prep before you use E.T.C. cement. The lubricant will prevent the cement from permanently bonding to the Brush&Bond, but will also provide a retentive, leak-proof collar around the margins. Once the crown is seated, light-cure the marginal excess and begin your clean-up. E.T.C. is a snap to clean up around the temp.

  • Esthetics: When dealing with anterior teeth, appearance really does matter. E.T.C. blends in beautifully with nearly any tooth and crown shade.
  • Eugenol-free: E.T.C. is a non-eugenol resin cement, so it won’t compromise the integrity of a bisacryl or acrylic temp like ZOE-based cements can, nor will it inhibit the set of the bonding agent and cement when you are ready to seat the definitive prosthesis.
  • Saving steps & time: E.T.C. comes in a 5ml, hand-dispensed, automix syringe so you can avoid the hassle of cartridge guns and hand-mixing. Conveniently, it self-cures deep under the crown in about four minutes, or you can speed the process by light-curing the margins. Simply peel away the excess cement and your patient is on their way.
  • Low viscosity: E.T.C. flows beautifully, so it covers the intaglio of the temporary crown in a nice, thin layer.

Frequently Asked Questions About ETC (Easy Temporary Cement)

Q. What type of cement is ETC?

A. ETC is a temporary resin cement.

Q. What are the benefits of ETC when compared to other temporary cements?

A. ETC was specifically formulated to address the most common problems clinicians have with temporary cements, the inability to retain the restoration for the required time interval. In addition to its superior retentive ability, other benefits of ETC include:

  • The flexibility and security of dual cure setting
  • It has low viscosity which allows for complete seating of restorations
  • Its translucent shading blends seamlessly with the surrounding tooth and temporary
  • Easy cleanup
  • Automix syringe

Q. Can I use ETC on implants?

A. Because ETC is NOT radiopaque, and excess flash cannot be seen on a radiograph. Retrieve is a better alternative for longer-term cementation on implants.

Q. How do I know when I should lubricate a prep?

A. Generally, to allow for easier removal of the restoration without damage to the underlying abutment, you should always lubricate preps that have either of the following characteristics:

  • A composite core
  • A prep than has been sealed with a bonding agent

Q. When lubrication is necessary, how much should I apply?

A. In cases where prep lubrication is deemed necessary, lubricate both the resin and dentin at least 1-2 mm above the margin to preclude the temporary from locking onto the prep.

Q. Will I be able to remove a crown if I forget to lubricate the abutment first?

A. It depends. If the abutment has long parallel walls, a composite core, a bonded resin sealer coat, undercuts or surface concavities, a temporary crown cemented without prior prep lubrication may need to be cut off to prevent damage to the underlying abutment/core complex.

Q. What should I lubricate the prep with prior to cementation of a crown with ETC?

A. You may use water soluble lubricants such as glycerin or K-Y Jelly. They allow for easier cleanup when the restoration is removed.

Q. Is ETC a dual-cure cement?

A. Yes. ETC can be light cured or allowed to self-cure on its own.

Q. How is ETC dispensed?

A. ETC is dispensed from an automix, 5 ml dual-barrel syringe through single use, disposable mixing tips.

Q. Is it necessary to fill the entire crown with cement?

A. In most cases a bead around the marginal area of the preparation works best. It seals the margin with minimal interference when seating and does not create excessive retention.

Q. How long should I wait before I start removing flash cement from the margin?


  • Self cure: Depending on the patient’s oral temperature, ETC will reach its gel phase between 2:00-3:00 minutes. You can then safely remove the flash material.
  • Light cure: ETC will reach its gel phase within three to four seconds of exposure to your curing light. You can then safely remove the flash material.

Q. How long does it take ETC to set?


  • Self cure: ETC sets in approximately 4 ½ minutes when self-curing.
  • Light cure: Marginal flash will be fully set after about 10 seconds of curing light exposure.

The exposure time required for ETC to set under a ceramic restoration will be dependent on the thickness and translucency of the crown, as well as the intensity of your curing light. ETC cannot be light cured under metal restorations.

Q. My ETC is not setting in self-cure mode. What should I do?


  • Has the material expired? (Check the expiration date) If your syringe of ETC has passed its expiration date stop using it. It is time to purchase another syringe of ETC.
  • Did you properly double bleed the cartridge as per the instructions before placing ETC in the restoration? If you did not double bleed the syringe before placement of ETC into the crown you may not be getting the proper mix ratio of the two components. This can prevent the materials from setting. Information on double bleeding can be found in the instructions that came with the syringe of ETC and here where a copy of the instructions can be downloaded and printed.

If you do not believe the inability of the material to set stems from one of the two reasons mentioned above, please call Parkell for further troubleshooting.
