resinluting

Resinluting refers to the process of cementing indirect dental restorations to prepared teeth using resin-based luting cements. These cements are adhesive materials that form a bond to both tooth structure (enamel and dentin) and the restoration, enabling retention and marginal seal. Resin luting cements come in several formulations, including conventional resin cements that are light- or dual-curing in combination with bonding agents, and self-adhesive resin cements that require fewer bonding steps.

Indications for resinluting include the cementation of all-ceramic and composite restorations such as crowns, inlays, onlays, and veneers, as well as some implant-supported restorations where adhesive bonding is advantageous. The choice of cement depends on factors such as restoration material, operatory conditions, esthetic demands, and the need for retrieval.

The procedure typically involves meticulous tooth preparation and isolation to prevent moisture contamination, followed by surface treatment of the tooth (etching and priming or bonding) and preparation of the restoration. The resin cement is applied to the restoration or tooth, the restoration is seated, and excess cement is removed before curing. Cement curing may be light-activated, chemically activated, or dual-curing, depending on the product and clinical situation. Final finishing and polishing complete the process.

Advantages of resinluting include strong bond strength to both tooth structure and many restorative materials, excellent esthetics, low solubility, and reduced microleakage when properly executed. Limitations include technique sensitivity, sensitivity to moisture during bonding, and potential polymerization shrinkage. Proper case selection, isolation, and adherence to manufacturer instructions are essential for successful outcomes.
