“…By designing regularly patterned surfaces, directional cell alignment, migration, and proliferation can be achieved [186,189]. Cell responses to laser textured zirconia-based ceramics with different patterns, such as grooves [60,190,191], pits [139], and grids [60,192,193], have been reported. Fig.…”

“…Several authors have also examined the cell adhesion of zirconia ceramics for dental implant applications by using surface topographies fabricated with femtosecond lasers. A nanosecond pulsed fiber laser was successfully used by Goyos-Ball et al [70] to produce square grid geometric structures with groove depths (1, 1, 5 and 3 mm) and groove spacing (10 and 30 mm) on the surface of 10CeTZPAl2O3. It was found that a groove depth of 1.5 mm and a groove spacing of 10 mm provided the most effective results for osteogenic differentiation.…”

The continuous need for high-performance implants that provide significant biological properties has led to extensive research into the topographic patterns of bioceramics in recent years. Their excellent aesthetics, biocompatibility, low plaque affinity, and ability to reproduce a natural-looking appearance have contributed to their success in dentistry. 3 mol% Yttria-stabilized zirconia (3YSZ) is gaining popularity as a material for dental implants due to its excellent mechanical properties and minimal degradation when exposed to body temperature. However, such materials show limited biological and antibacterial performance for dental applications. The purpose of this work was to develop microtopographies on the surface of 3YSZ ceramic by laser ablation technique, in order to improve its biological response and antibacterial behaviors. Two types of microtextures, including micro-grooves and micro-channels geometries were fabricated onto the zirconia ceramics using the laser ablation technique. The effects of different microtextures on the wettability, biological and antibacterial behaviors of 3YSZ ceramics were studied. The results indicate that all of the microstructure patterns are capable of improving the performance of 3YSZ. Wettability is a decisive factor that determines the antibacterial performance of textured zirconia ceramics. The microtextured surfaces all display hydrophobic behavior, thus yielding an effective improvement of antibacterial performance for 3YSZ ceramics. Cell-surface interactions were assessed for 7 days on both zirconia textured surfaces and a nontextured control with pre-osteoblast MC3T3-E1 cells. The obtained results showed the positive influence of textured zirconia surfaces on cell biological response.

“…Femtosecond laser was used to machine dental ceramic implants made of zirconia-toughened alumina (ZTA) [18], or to induce regular patterns on an alumina-toughened zirconia (ATZ) surface [19]. And similarly to what was attempted in monolithic zirconia, laser-modifications of alumina-zirconia composites were used to induce osteogenic differentiation of human mesenchymal stem cells [20] and favour viability of osteoblast-like cells [21], or to help osseointegration of endosseous dental implants [22]. In addition to the microstructural changes induced in zirconia by the melting/ablation/quenching sequence, alumina-zirconia composites show also chemical changes, as reported by Ackerl et al [18] who reported that "Alumina […] seemed to dissolve approaching the surface".…”

Laser engraving is more and more commonly used to write permanent identity features on medical devices. In particular, it is performed on ceramic heads for hip prostheses. Since these components are submitted to high mechanical loading during long periods of time (several years), it is critical to assess the influence of laser engraving on their durability. In the present article, laser marking of zirconia-toughened alumina and alumina-toughened zirconia resulted in an important colour change. It did not affect notably the resistance to hydrothermal ageing, despite important microstructural changes (in particular formation of a zirconia-alumina solid solution layer some tenths of micrometres thick). The formation of this original microstructure was explained by the fast cooling rate after lasing.
