Description
Lankes and four co-authors ask whether sandblasting can replace acid for preparing dental ceramics, in this two thousand twenty-four study. Before a ceramic crown is glued in, its surface is usually etched with hydrofluoric acid, a hazardous step dentists would gladly avoid.
The team abraded feldspar, lithium silicate, and zirconia samples with alumina particles of two sizes at two pressures, and compared them with etched controls. They measured surface energy, roughness, and how strongly resin cement stuck, before and after heat aging. Abrasion at the higher pressure matched or beat etching for the silicate ceramics, and zirconia bonded strongest overall with coarser particles. The results support dropping the acid for these materials when the settings are right.
