Novel laser textured surface designs for improved zirconia implants performance

Laser surface texturing of zirconia-based ceramics for dental applications: A review

“…The mechanical properties of materials are expected to be influenced more by FLB processing than DLIP. Several research works [61,149] reported a decrease in flexural strength for FLB laser textured samples, and there is a positive correlation between the reduction in flexural strength and the laser ablation depth (Fig. 9).…”

“…The topography and dimension of the textures produced by FLB is influenced by J o u r n a l P r e -p r o o f several parameters, including laser spot size, laser power, scan speed, and scan strategies [61]. The smallest feature size is limited by the laser spot size, which typically ranges from several micrometers to tens of micrometers.…”

“…First, there is no surface contamination onto the implant during surface processing because the laser treatment is a contact-free process. Second, laser processing can produce hierarchical surface structures with regular patterns and therefore control the wettability of the surface, which is believed to have a big influence on the cell adhesion behavior [59][60][61]. Third, laser processing, especially with ultrafast lasers, can be applied to any kind of material irrespective of its hardness and mechanical strength [62].…”

Influence of ns-Nd:YAG laser surface treatment on the tensile bond strength of zirconia to resin-matrix cements

“…The null hypothesis of this study was rejected, as the laser textured zirconia surfaces revealed significantly higher bond strength to resin cement than that recorded for conventionally alumina blasted ones (p<0.05). The laser conditions used in this work were selected based on previous experiments in a way that surfaces with different pattern arrangement could be produced in a controlled manner (Figure 2b-d) [25]. The surfaces produced consisted of equally spaced valleys and protrusions, being closer in the G8L samples and further apart in the G16L samples.…”

Bioactive Glass Coated Zirconia for Dental Implants: a review

“…Their biological inertness and electrical passivation have made ceramics a promising material in the medical equipment and medicine. In comparison with metallic implants, zirconia-based ceramics show minimum ion release and are biologically inert [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Modern Ti implant technologies are being introduced due to possible combination of immunologic and aesthetic aspects of Ti and Ti alloys.…”
