Neue CAD/CAM-Werkstoffe und ihre Befestigung: Plug-and-Play?

Zusammenfassung

Das Ziel der vorliegenden Studie war es, die Befestigung von Seitenzahnkronen aus CAD/CAM-Komposit, Hybrid- und Lithiumdisilikatkeramik in 2 Aushärtungsmodi (Licht- und Dunkelhärtung) zu untersuchen. Hierfür wurde die Randdichtigkeit nach künstlicher Alterung im Kausimulator überprüft. Die Ergebnisse zeigten, dass für die Befestigung von CAD/CAM-Kompositen eine signifikant höhere Randdichtigkeit bei separater Lichthärtung des Adhäsivs und des Befestigungskomposits erzielt werden konnte.

Abstract

The aim of the present study was to investigate bonding of posterior full crowns made of CAD/CAM composites, hybrid ceramics and lithium disilicate ceramics for two curing modes (light and chemical curing). After artificial aging in a mouth-motion simulator, the marginal sealing was investigated. It could be shown that a separate light curing of the adhesive and luting cement causes a significantly higher marginal sealing for CAD/CAM composites.
