Let me introduce you to SpeedCem Plus from Ivoclar Vivadent. Available in three shades, it is a self-adhesive, self-curing resin cement with a light-curing option that can be used for a variety of clinical applications:

• Metal (PFM, gold, nonprecious metal) inlays, onlays, crowns, and endodontic posts
• Lithium disilicate (e.g., e.max) inlays, onlays, and crowns
• Zirconium oxide restorations
• Cement-retained implant restorations
• Fiber-reinforced composites (endodontic posts)

Features of the cement

You can imagine that a gold crown or some zirconia crowns may not allow a curing light to adequately cure a cement, right?! This is why a self-curing cement is important for these clinical scenarios. Cements with self-curing properties add an extra measure of safety when cementing restorations that are opaque or block out light. SpeedCem Plus forms a strong, reliable chemical bond to dentin, enamel, and a wide variety of dental materials.

It's also user-friendly. SpeedCemPlus provides the clinician with simple protocols and easy and fast cleanup. It is a true self-adhesive; SpeedCem Plus does not require the application of etch and/or bonding agents to the tooth prior to cementation. Additionally, no silanating agent or zirconia primer needs to be applied to the surface of a zirconia restoration prior to cementation with SpeedCem Plus. A study by Ghuman and Donovanfound that SpeedCem Plus achieved consistent bond strength values even without the application of a primer. (1) Keep in mind, it is necessary to apply a primer or silanating agent to all-ceramic restorations. (2) SpeedCem Plus was also tested for strength when crowns were cemented to dentin that had been blotted dry, with five seconds of drying and ten seconds of drying. (3) SpeedCem Plus had significantly greater shear bond strength when compared to other self-adhesive resin cements. (3) This is a beneficial feature because we can depend on a strong bond when cementing crowns to dentin that is moist, partially dry, or very dry.

Removal of excess cement is easy. After the restoration is fully seated, cure each quarter surface for one second. SpeedCem Plus will set to a rubbery consistency that is easy to remove with an explorer. Any fully set material can be removed with a scaler. SpeedCem Plus is also radiopaque (figure 1), so residual cement can be visualized on a radiograph and removed.

Figure 1: SpeedCem Plus is radiopaque. It has a similar radiopacity to Multilink Automix.

Protocol for cementation

Cementation of zirconium oxide crowns and bridges can be accomplished in a few easy steps:

1. Try in the crown and ensure fit. After the try-in, clean the restoration with Ivoclean.

2. Dispense SpeedCem Plus into the crown.

3. Light cure each quarter surface for one second. The excess cement will have a gel-like consistency that can be removed for easy cleanup. Apply Liquid Strip around the margins to prevent an oxygen-inhibition layer.

4. Allow the cement to self cure. The total working and setting time of the cement in self-cure mode is approximately three minutes.

If you are looking for a cement that is efficient and dependable in variety of clinical situations, SpeedCem Plus may be the cement that you are looking for. If you are attending the American Dental Association meeting this year, visit Ivoclar Vivadent’s booth and look for SpeedCem Plus.
