A 44-year-old female presented for full mouth rehabilitation. Because a natural-looking, esthetic outcome was as important to the patient, allceramic restorations fabricated from a lithium disilicate material (IPS e.max Press, Ivoclar Vivadent) were selected.

To complete the preparations, the patient was anesthetized (Ultracain D-S forte, Sanofi Aventis). Proper reduction was accomplished using the appropriate burs in an electric handpiece (EXPERTmatic LUX E25L, KaVo). For this case, the preparation design enabled the use of an adhesive cementation technique. To ensure the accuracy of the margin details during impression-taking, retraction cord was placed (ROEKO Stay-put, COLTENE).

When the definitive restorations were ready to be seated, the bonding surfaces of the dentition and the restorations were properly conditioned. This helped to establish a strong and durable bond between the tooth structure and restorative material that ultimately ensured the longevity of the restorations.

The tooth structure was conditioned using a self-etch adhesive system (Multilink Automix Primer A/B, Ivoclar Vivadent). The internal aspects of the restoration, which were pretreated with HF acide in the dental laboratory, were cleaned using a product that enhances bonding between restorative primers and treated surfaces (Ivoclean, Ivoclar Vivadent). A universal restorative primer (Monobond Plus, Ivoclar Vivadent) was then applied to the internal aspects of the restorations.

A self-curing luting cement with light cure option (Multilink Automix Next Generation, Ivoclar Vivadent) was applied to the restoration for definitive placement. This process allowed for controlled curing of the luting material, as well as easy cleanup and removal of excess material.

All-ceramic restorations seated with an adhesive luting composite can provide a reliable treatment option for achieving highly esthetic dental reconstructions in modern dentistry. Hard-tissue defects can now be restored more conservatively than when conventional cements are used, as demonstrated in this case.
