FDA Product Code EMA: Cement, Dental

FDA product code EMA covers dental cements used for the luting of restorations and the cementation of crowns, bridges, and orthodontic appliances.

These materials form a stable bond between tooth structure and restorative materials, sealing the margin against bacterial ingress and providing mechanical retention. Available formulations include resin, glass ionomer, zinc phosphate, and resin-modified glass ionomer cements.

EMA devices are Class II medical devices, regulated under 21 CFR 872.3275 and reviewed by the FDA Dental panel.
