About resin cements
Resin cements are the most recent luting material developed for dentistry, and they can form a chemical bond with dentine and enamel. They divide into adhesive cements, used after the tooth is etched with phosphoric acid and an adhesive is applied, and self-adhesive cements, which call for neither step except on enamel. A self-adhesive cement carries components such as MDP that bond to the tooth and to the restoration at the same time, and a review notes that glass ceramics still need the etching and silane layer. They are also grouped as chemical-cure, light-cure or dual-cure, and a dual-cure cement holds both chemical and light initiators, so its catalyst finishes hardening the cement where light cannot reach.
A luting agent is any material used to attach or cement indirect restorations to prepared teeth. A review lists the long-term cements as zinc phosphate, zinc polycarboxylate, glass ionomer, resin-modified glass ionomer and resin cement. They fall into two families by composition, water-based and resin-based.
How the types of permanent cement differ
- Glass Ionomer & RMGI Cements — Water-based, and it releases fluoride. The resin-modified kind sets by an acid-base reaction and by polymerisation together, and ISO 9917-2 is the standard for those.
- Resin Cements — Resin-based rather than water-based, and chemically similar to composite filling material. A restoration cemented adhesively has to be sectioned to come off.
- Dental Cements — A water-based cement of this kind sets by an acidic reaction and holds the restoration without bonding to it. A crown cemented with zinc phosphate or polycarboxylate can be removed with care instead of being sectioned.
What to look at when choosing a permanent cement
Film thickness: the ADA standard for dental cements sets a maximum of 25 microns for a luting cement.
How it is supplied: these cements come hand-mixed or encapsulated for mechanical mixing. A review notes that modifying the powder-to-liquid ratio can increase the solubility of a luting agent threefold, and calls that a frequent cause of clinical failures.
Age and track record: zinc phosphate has been in use since 1878 and has high compressive strength and a reasonable working time, with high solubility in oral fluid, low tensile strength and the potential for hypersensitivity from its initially low pH among its drawbacks.
Light reaching the cement: a review reports light-cured cements being used for restorations under 1.5 mm thick that let enough light through, and the chemical cure of a dual-cure cement being what sets it under zirconia and thick ceramic. Excess cement: a review notes that removing resin cement completely from margins that are hard to reach is a problem for restorations with margins below the gum line.
Standard: ISO 4049 covers polymer-based luting materials for cementing inlays, onlays, veneers, crowns and bridges, but not those with an adhesive component inside the material. FDA class: zinc oxide-eugenol is a Class I device and dental cement other than zinc oxide-eugenol is Class II (21 CFR 872.3275).
