The research aims to investigate how storage time after surface treatment affects the surface free energy and bond strength of composite cement on zirconia.
Measured surface free energy (SFE) after different storage times
Assessed bond strength of composite cement to zirconia
Conducted adhesive failure analysis over time
Significant decrease in surface free energy with increased storage time
Increased adhesive failures noted with longer storage periods
Shorter storage intervals recommended to enhance bonding effectiveness
Abstract
Given the significant decrease in SFE with prolonged storage and adhesive failures to zirconia tended to increase over time, minimizing the interval between surface treatment and cementation is recommended.
