Nanostructured titanium alloy surfaces for enhanced osteoblast response: A combination of morphology and chemistry

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Different real‐time degradation scenarios of functionalized poly(ε‐caprolactone) for biomedical applications

“…Similarly to previously studied G surfaces, 35 the results showed higher cell viability (more than 40%) on samples with pNaSS over NG equivalents. Besides, no statistical difference was verified between the viability of the cells cultivated on non‐degraded PCL and after 24 weeks of experiment regardless of the degradation medium, and in consequence, the degradation mode.…”

Multi-Scale Surface Treatments of Titanium Implants for Rapid Osseointegration: A Review

“…In order to overcome this limitation, surface treatment technologies can be used to attain bioactive surfaces on Ti substrates [ 40 , 41 , 42 , 43 ]. The macro-scale, micro-scale, and nano-scale morphology of the implant surfaces have a crucial influence on the early bone formation and fixation [ 16 , 44 , 45 ]. Most titanium implant surfaces with certain roughness characteristics were fabricated through mixed technologies (e.g., grit-blasting, acid-etching).…”

“…The nano-scaled topography condition is in the range of less than one micrometer. There are various surface morphologies made using different techniques and the related adjusting process parameters, for instance, nano pit, nanotubular, nanowire, nanorod, and nanopore [ 44 , 69 , 70 , 71 , 72 , 73 ]. Accordingly, the Three-Dimensional Printing (3DP) and Laser Surface Texturing (LST) procedures improve the surface morphology at the macro-scale, while the grit-blasting and acid-etching procedures can produce surface features and morphologies at the micro-scale [ 74 , 75 , 76 , 77 , 78 , 79 , 80 ].…”
