“…It can be seen that surface roughness increases when the pitch decreases for the grid pattern, there is a positive correlation between the processing rate and surface roughness, that is, the surface roughness increases with the pitch increasing, which is consistent with previous investigations described in Ref. 2. However, except for samples with a pitch of 90 μm, the Ra for the channel pattern increases as the processing pitch decreases, and when the pitch decreases to 70 μm, the surface roughness decreases.…”

This paper presents the modification of wettability by nanosecond laser surface textured followed by silanization to fabricate the superhydrophobic zirconia surface. Surface modification by varying the pitch between channels leads to micro‐channel and micro‐grid pattern with different surface roughness. The generated morphological and metallurgical modifications of the surface are measured by scanning electron microscopy (SEM) and X‐ray photoelectron spectroscopy (XPS). Numerous micro‐pits and cracks in the laser‐treated areas can be observed from SEM, which indicates crack propagation dominating the process of laser ablation of zirconia. The surface is superhydrophilic with laser‐texturing instantly, whose wettability is modified over time. By analyzing the XPS, carbon content, especially C‐C (H) groups, is important for the time‐dependent wettability. The hydrophobicity of all laser‐textured surfaces is improved after silanization. Laser texturing with smaller pitch (50 μm and 70 μm) leads to superhydrophobic surfaces after silanization, which may be due to the modification of physicochemical properties of substrate by very rapid local heating and cooling on the thick surface layer. Overall, the investigations indicate that wettability modifications can be attributed to the surface's microstructure, which depend on laser processing parameters, and chemical composition, especially in terms of −CF3, −CF2, and C‐C (H).

“…Several studies have shown that laser-textured surface can promote cell adhesion, proliferation, and spreading on various biocompatible metal alloys [190][191][192]. The effects of surface texture on the tribological behavior of orthopedic implants have been investigated, and the main benefits include improved wettability, friction, and wear performance when compared to smooth surfaces [193][194][195].…”

Recent years have witnessed a rapid growth of the laser market. Figure 1 shows the recent revenues of laser sales with about 50% increase in revenue over recent four years , which far exceeds the growth of other industrial sectors. More than one third of this revenue belongs to the category of laser materials processing arena. Undoubtedly, lasers have been playing increasingly important roles in various industrial manufacturing sectors. This article is to capture some of important developments in the rapidly growing areas of laser-based manufacturing and materials processing and also describe important technological issues pertaining to various laser-based manufacturing processes. The topics to be covered in this paper include more popularly used processes in industry such as laser additive manufacturing, laser-assisted machining, laser micromachining, laser forming, laser surface texturing, laser welding, and laser shock peening, although there are several additional areas of laser applications. In each section, a brief overview of the process is provided, followed by critical issues in implementing the process, such as properties, predictive modeling, and process monitoring, and finally some remarks on future issues that can guide researchers and practitioners.

“…Nevertheless, implant technology has devoted significant efforts to modify zirconia regarding morphological and bioactive aspects that is desirable for an appropriate cell attachment, proliferation, and differentiation during the surrounding bone healing [3,26]. On improving zirconia surfaces, several physicochemical methods have been used such as: grit blasting [27], laser treatment [28], micro-machining, CVD, and PVD. The development of coatings composed of silica, magnesium, graphene, dopamine, and bioactive molecules has been assessed although the development of a functionally graded material for implants has shown an enhancement in mechanical behavior and biological response face [28].…”

Background: Zirconia has emerged as a versatile dental material due to its excellent aesthetic outcomes such as color and opacity, unique mechanical properties that can mimic the appearance of natural teeth and decrease peri-implant inflammatory reactions. Objective: The aim of this review was to critically explore the state of art of zirconia surface treatment to enhance its biological and osseointegration behavior in implant dentistry. Materials and Methods: An electronic search in PubMed database was carried out until May 2018 using the following combination of key words and MeSH terms without time periods: "zirconia surface treatment" or "zirconia surface modification" or "zirconia coating" and "osseointegration" or "biological properties" or "bioactivity" or "functionally graded properties". Results: Previous studies have reported the influence of zirconia-based implant surface on the adhesion, proliferation, and differentiation of osteoblast and fibroblasts at the implant to bone interface during the osseointegration process. A large number of physicochemical methods have been used to change the implant surfaces to improve the early and late bone-to-implant integration, namely: acid etching, gritblasting, laser treatment, UV light, CVD, and PVD. The development of coatings composed of silica, magnesium, graphene, dopamine, and bioactive molecules has been assessed although the development of a functionally graded material for implants has shown encouraging mechanical and biological behavior.
