reactive resin groups to bond to the cement and therefore the strength of bond will be less. preparation of inlays are with close to parallel walls and a key on the occlusal surface- this is sometimes sufficient for retention purposes so adhesive resin luting cements may not be needed. ceramic inlays can also be cured with chemically cured resin composite or dual cured resin composite. according to a 10-year evaluation of ceramic inlays cemented with both chemically cured resin composite and dual cured resin composite; the inlays cemented with chemically cured survived longer after cementation. after 10 years the survival of the chemically cured inlays were 100% and of the dual cured were 77%. bonding agents can be applied to dentine before cementation of inlays and onlays. this is something that is very useful as dentine contains a lot of mineral, which makes binding more problematic. a bonding agent that is applied straight after the preparation has been finished will give rise to greater dentine bond strengths. if the bonding agent is applied just before cementing the inlay/onlay or if no bonding agents are applied; the dentine bond strengths will be noticeably lower. in conclusion; the type of luting agent and properties have an impact on how long ceramic/inlays will stay cemented in the mouth.
