Purpose: The aim of the study was to examine the connection between the zirconia substructure and the porcelain in the dental crowns subjected to simulated occlusal forces. Design/methodology/approach: All-ceramic dental crowns were subjected to Vickers hardness examination, testing of compressive strength and observations of breakthroughs on the SEM. Findings: Based on the research, it was found...
Purpose: The purpose of the work was to evaluate the compressive strength of metalceramic connections in the fixed dental restorations. Design/methodology/approach: Restorations were made on a model of the natural patient's dentition which was developed specifically for this study. The study included 10 metal - porcelain crowns, for each group of teeth. Their production used Remanium 2000+ alloy and...
Purpose: The aim of the work was to test hardness of composite dental materials with different resins in relation to different light-curing parameters. Design/methodology/approach: The following article provides and insight into factors influencing hardness of composite materials. Standardized samples made of Herculite XRV based on a methacrylate resin and Filtek Silorane based on silorane resin were...
