Ivoclar Vivadent announces that IPS Empress and IPS d.SIGN each received the highest clinical performance ratings possible from THE DENTAL ADVISOR. Based on an 8-year clinical performance evaluation of crowns, inlays/onlays and veneers, IPS Empress was rated an excellent 5 +. Similarly, IPS d.SIGN anterior and posterior crowns, as well as 3- and 4-unit bridges, also received an excellent 5 + rating following a 1-year clinical performance evaluation. Overall, the two esthetic indirect restorative systems received positive reviews for resistance to fracture/chipping; esthetics, shade matching, and vitality; wear resistance; and patient satisfaction.
“Everyone at Ivoclar Vivadent is dedicated to providing dentists and laboratory technicians with esthetic, functional and durable restorative products that meet their needs,” commented Ivoclar Vivadent president Robert A. Ganley. “That IPS Empress and IPS d.SIGN have received such ratings in the clinical arena reinforces our commitment to delivering excellent materials that continue to fuel the Esthetic Revolution.”
Consultants for THE DENTAL ADVISOR noted that during the evaluation period, 97% of IPS Empress restorations exhibited no fractures, a rate comparable to PFM crowns. IPS Empress also demonstrated very good-to-excellent esthetics, with evaluators commenting that no change from the initial shade was noted, and all restorations maintained their gloss. Additionally, very little marginal staining due to microleakage was found in the IPS Empress restorations observed, which may be attributed to successful bonding with Variolink dual-cured adhesive resin cement. There were no visual signs of wear on IPS Empress restorations, and patient satisfaction was very high “because of excellent esthetics, lack of sensitivity and long-term success of these restorations.”
Similarly, the glass ceramic of the IPS d.SIGN restorations was found to be highly esthetic, with 91% of the restorations rating excellent, and 9% rating very good. The IPS d.SIGN restorations also received high ratings for vitality, with evaluators noting that “the ceramic provided a life-like appearance and maintained surface luster.” At one year, 97% of the restorations maintained intact ceramic, and 100% were rated excellent for wear resistance of the ceramic, with no visual signs of wear to the opposing dentition. The high patient satisfaction ratings that were received may be attributable to the excellent results observed in the other categories evaluated.
