“…These results show that the presence of amorphous Ta The adhesion strength and degradation behavior of coatings are important influencing parameters for performance analysis. Cao et al [94] compared the four coating groups including Polylactide-L-lactide-CO-ε-caprolactone (PLC) coatings, PLC coating with antibiotics, micro-arc oxidation (MAO)/PLC double coating, and MAO/PLC double coating with antibiotics on titanium surface. The result shows that the use of MAO coating is very effective to increase the adhesion strength and load to failure of coating at the interface.…”

Titanium, stainless steel, and CoCrMo alloys are the most widely used biomaterials for orthopedic applications. The most common causes of orthopedic implant failure after implantation are infections, inflammatory response, least corrosion resistance, mismatch in elastic modulus, stress shielding, and excessive wear. To address the problems associated with implant materials, different modifications related to design, materials, and surface have been developed. Among the different methods, coating is an effective method to improve the performance of implant materials. In this article, a comprehensive review of recent studies has been carried out to summarize the impact of coating materials on metallic implants. The antibacterial characteristics, biodegradability, biocompatibility, corrosion behavior, and mechanical properties for performance evaluation are briefly summarized. Different effective coating techniques, coating materials, and additives have been summarized. The results are useful to produce the coating with optimized properties.

“…The additive techniques use a flow of plasma to deposit on the implant surface different materials, such as titanium powder, hydroxyapatite powder, or titanium microspheres. The degree of bacterial proliferation on these surfaces is also influenced by the type of surface [44,45,46,47,48,49,50,51,52] (Figure 1, Figure 2 and Figure 3).…”

The field of dental implantology has made progress in recent years, allowing safer and predictable oral rehabilitations. Surely the rehabilitation times have also been reduced, thanks to the advent of the new implant surfaces, which favour the osseointegration phases and allow the clinician to rehabilitate their patients earlier. To carry out this study, a search was conducted in the Pubmed, Embase and Elsevier databases; the articles initially obtained according to the keywords used numbered 283, and then subsequently reduced to 10 once the inclusion and exclusion criteria were applied. The review that has been carried out on this type of surface allows us to fully understand the features and above all to evaluate all the advantages or not related. The study materials also are supported by a manufacturing company, which provided all the indications regarding surface treatment and confocal microscopy scans. In conclusion, we can say that, thanks to these new surfaces, it has been possible to shorten the time necessary to obtain osseointegration and, therefore, secondary stability on the part of implants. The surfaces, therefore, guarantee an improved cellular adhesion and thanks to the excellent wettability all the biological processes that derive from it, such as increases in the exposed implant surface, resulting in an increase in bone-implant contact (BIC).

“…The goal of the paper by Cao et al was the development of a polylactide-based, resorbable double coating on titanium implants, through micro-arc oxidation combined with dip coating [5]. The resorbable coatings, also with embedded antibiotics, showed adhesive properties on Ti-6Al-4V implants, being a promising substrate for bone reconstruction.…”
