dental compomers, also known as polyacid-modified resin composite,
dental compomers, also known as polyacid-modified resin composite, are used in dentistry as a filling material. they were introduced in the early 1990s as a hybrid of two other dental materials, dental composites and glass ionomer cement, in an effort to combine their desirable properties: aesthetics for dental composi...

the use of the luting version of compomer
the use of the luting version of compomer is not recommended for all-ceramic crowns, nor as a core or filling material. see 'water uptake' in properties section above for more details. compomer luting cement can however be used for cast alloy and ceramic-metal restorations.

it is important to note that compomers do not bond to tooth tissue like glass ionomer cements; this is the same issue with dental composites. it is therefore essential to use bonding agents to aid adhesion of the compomer to tooth.

handling and ease of use of composites is generally seen as good by dental professionals. compomers are available in both normal and flowable forms, with the manufacturers of the flowable compomers claiming that they have the ability to shape to the cavity without the need for hand instruments.
