Effect of Er:YAG Laser Irradiation on the Flexural Fatigue Strength of a 4YSZ Ceramic

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT This study aimed to evaluate the effect of Er:YAG laser surface treatment on the flexural fatigue strength of 4YSZ ceramics, with or without resin cement application. Disk‐shaped zirconia ceramic specimens (Ø = 15 mm, thickness = 1.2 mm of IPS e.max ZirCAD MT BL) were prepared and randomly assigned to 10 groups based on two factors: “surface ...

ELECTRON MICROSCOPIC FRACTOGRAPHY

, 1962
Electron microscopic fractography comprises the examination of replicas of fracture surfaces under the electron microscope and is a valuable tool for studying the fracture micromechanism and for analyzing service failures. The techniques of fractography are described, and the direct carbon and plastic- carbon methods of replication are compared.
