Resin Cements (e.g. 3M™ RelyX ARC Adhesive Resin Cement)
Advantages
High mechanical strength
High fracture toughness
Low wear
Insoluble (will not erode) in the oral environment
Offers retention for difficult preparations (i.e. the prepared tooth is short or extremely tapered)
Esthetic shades are available for bonding all-ceramic restorations
Disadvantages
Requires placement of a dentin/enamel adhesive
Moisture control is critical to ensure high bond strengths
Removal of excess cement may be difficult with some brands
Removal of a crown bonded with resin cement is extremely difficult
Resin Modified Glass Ionomer Cement (e.g. 3M™ RelyX™ Luting Cement formerly known as Vitremer Luting Cement)
Advantages
Easy to use - Easy to clean-up
Initial high and sustained flouride release
Chemical adhesion to tooth
Not soluble in oral environment
Moderate mechanical strength
High fracture toughness
Very low levels of postoperative sensitivity when used according to manufacturer’s instructions.
Disadvantages
Desiccation of the prepared tooth prior to cementation may cause postoperative sensitivity.
Zinc Phosphate Cement (Fleck’s® Cement from Mizzy)
Advantages
History of success
Adjustable working time
High impact resistance
High rigidity
Inexpensive
Disadvantages
Post-op sensitivity
Long set time
Mixing is technique sensitive
Mixing is time consuming
Poor adhesion
High solubility
Low mechanical strength
Low fracture toughness
Polycarboxylate Cement (e.g. Durelon®, ESPE America)
Advantages
Lack of post-op sensitivity
Long history of success
Tolerant of mild contamination
Chemical adhesion to tooth
Appearance change at end of working time
Inexpensive
Disadvantages
Clean up timing is critical
High solubility
Low mechanical strength
Low fracture toughness
Conventional Setting Glass Ionomer Cements (e.g. Ketac-Cem®, ESPE, Fuji I®, GC America)
Advantages
Chemical adhesion to tooth
Fluoride release
Easy to mix
Moderate mechanical strength
Disadvantages
History of post-op sensitivity
Low fracture toughness
Moderate solubility in oral environment
Moisture sensitive during setting
