Excellent rating for Multilink Automix
Schaan, Liechtenstein – 5 December 2013
The independent US test institute The Dental Advisor tested Multilink Automix, the universal self-curing luting composite with light-curing option from Ivoclar Vivadent, over a period of three years and has now awarded the product the highest possible rating of Five Plus.
In this study, 356 all-ceramic restorations, cemented with Multilink Automix, were evaluated. A total of 275 restorations were placed on molars and 81 restorations on pre-molars. Fifty per cent of the restorations were fabricated from leucite-reinforced glass-ceramic, 44 per cent from lithium disilicate glass-ceramic and 6 per cent from zirconium oxide. At the three-year recall, all the restorations were rated on a scale from one to five. All the restorations received excellent results in the areas of esthetics, resistance to marginal discolouration, freedom from sensitivity and retention. Multilink Automix received a 97 per cent overall rating.
Multilink Automix maintained excellent colour stability in 100 per cent of the restorations, ensuring optimal esthetics. Furthermore, Multilink Automix showed a very low tendency towards marginal discolouration. Ninety-nine per cent of the restorations demonstrated no marginal discolouration at the recall. Only three restorations (<1 per cent) had to be replaced as a result of discolouration.
The majority of patients reported no postoperative sensitivities. Three patients stated that there was some initial mild sensitivity that resolved in a short time. The final subject of investigation was the retention force: Multilink Automix was used for the cementation of inlays, onlays and crowns made of zirconium, lithium disilicate and leucite-reinforced ceramic in the posterior region. Debonding occurred only in 2 per cent of the restorations.
