A clinically focused discussion of luting materials

摘要: A luting agent’s primary function is to fill the minute void between an indirect restoration (definitive or provisional) and tooth (or implant abutment) mechanically lock in place prevent dislodgement during function. The purpose of this paper provide a clinically focused discussion on broad spectrum materials currently available help general practitioner make appropriate choices. Resins are typically formulated for specific offer strength, aesthetics, flexible working times, very low solubility yet technique sensitive, expensive often hard clean-up. Glass-ionomers good strength optical properties plus potential fluoride release/recharge but may have short sensitive moisture dehydration early on, take time fully set. Resin-modified glass-ionomers hybrid, dual-phase which manipulated like glass-ionomer set quicker stronger. Zinc phosphate cement, used successfully over century lute well-fitting metal metal-ceramic definitive restorations, inexpensive, rigid material displays high compressive acidity can be problems. Polycarboxylate cement (a hybrid zinc phosphate) has lower tensile less injurious pulp. oxide eugenol non-eugenol cements sealing abilities their relatively strengths, inherent brittleness, limit usage provisional restorations supported crowns. Claims multi-purpose universal use by manufacturers somewhat confusing overwhelming. Even so, busy must sufficient knowledge choose agent each unique clinical situation.
