How to cement PFM and full alloy crowns

After you’ve removed the temporary restoration. Remove any leftover temporary cement with a polishing brush and fluoride-free cleaning paste then dry the tooth surface with dry compressed air.

Next, you’ll want to try in your new restoration to confirm the shade, fit and occlusion.

When you’re done, thoroughly rinse the restoration with water and dry with compressed air. Next, using cheek retractors and a bite block to provide a clear working environment, clean the teeth with fluoride-free paste, rinse with water, and dry with compressed air. You’re going to want to avoid over-drying the teeth. Now apply SpeedCEM Plus with the applicator tip directly to the internal surface of the restoration. Now seat the restoration and hold it in place using a light, yet constant pressure. Light-cure excess material around the cement line for 1 second at a distance of 10 – 15 mm and remove the excess material with a scaler. Before the final curing, you’ll need to cover the restoration margins with Liquid Strip or glycerine immediately after excess removal to prevent oxygen inhibition. Light-cure the cement for at least 20 seconds per quarter tooth, the remainder of the cement will auto-cure. Rinse off the Liquid Strip or glycerine. Adjusting the proximal areas is easy using ContacEZ polishing strips, you can then polish the restoration margins and occlusion. Finally, apply a thin film of fluoride polish and dry with compressed air.
