Unconventional milling of zirconia-based bioceramic material with nanosecond pulsed laser

Fabrication of dental restorations made zirconia-based biomaterials with enhanced mechanical and tribological properties together customized surface topography microstructure for promoting enamel adhesion cell proliferation while hindering bacterial spreading is a very challenging task to accomplish through conventional machining operations. In fact, traditional milling processes sintered ceramics are typically labor-intensive, therefore expensive time-consuming, these aspects can be further exasperated when microsized features required. On the other hand, unconventional techniques such as laser represent suitable solution produce miniaturized individualized structures on advanced since it non-contact thermal process that ensures elimination cutting forces allows hard brittle materials machined without need special equipment which requires high investments long processing times. this context, study aims investigate capability nanosecond pulsed fiber machine samples yttria-stabilized zirconia systematic experimental approach in order identify most operational parameters combinations ensure obtainment specific topographies minimizing time. The carried out by using 30 W Q-switched Yb:YAG controlling beam scan speed, strategy hatch distance following multi-level factorial design-based experimentation. adoption technology results high-repeatable, accurate time-saving allowing easy control outcomes.
