What is Effect of Abrasion vs. Etching on Lithium Disilicate Strength about?

This study investigates the effects of alumina particle abrasion and hydrofluoric acid etching on the flexural strength of lithium disilicate ceramics, specifically e.max CAD. Results indicate that alumina abrasion at pressures of 100 kPa and above significantly reduces flexural strength, while hydrofluoric acid etching does not adversely affect it. Clinicians are advised to use hydrofluoric acid etching for micromechanical retention instead of alumina abrasion.
