“…This constitutes an interesting result given the high sensitivity of osteoblasts to roughness at different scales [7,9,[38][39][40][41] and the strong influence of fractal dimension on osteoblastic adhesion and differentiation [10]. Regarding the roughness parameters, although the lack of standardization in the measurements makes comparison difficult with other studies, the values of S a , S dr , S ds and S ci which were obtained here fall within the range of the reported values for commercial dental implants with proved high success rate [8,[42][43][44].…”

Rough surfaces have been shown to promote osseointegration, which is one of the keys for a successful dental implantation. Among the diverse treatments proposed to roughen zirconia, hydrofluoric acid (HF) etching appears to be a good candidate, however little is known about this process. In this work, the effect of HF concentration and etching time on the surface topography and chemistry of yttria-stabilized zirconia was assessed.Besides, to understand the etching mechanism, the reaction products present in solution and on the surface were characterized. The results indicate suitable parameters for a fast and uniform roughening of zirconia. The formation of adhered fluoride precipitates on the surface is reported for the first time and highlights the importance of cleaning after etching. Finally, it is shown that monitoring the time allows controlling the surface roughness, smooth-rough transition and fractal dimension, which should make possible the fabrication of implants with an optimal topography.

“…In this regard, the traditional surface treatment methods such as grinding, grit blasting, ion implantation, thermal spraying, etc. cannot be employed because they do not help in obtaining a homogeneous surface modification throughout the entire structure [86][87][88][89][90]. Hence, the recent focus was on chemical and/or electrochemical methods because acid-based solution can penetrate through the porous structures through the interconnected pores, producing a homogeneous surface throughout the entire structure [86,[91][92][93].…”

We elucidate here the process-structure-property relationships in three-dimensional (3D) implantable titanium alloy biomaterials processed by electron beam melting (EBM) that is based on the principle of additive manufacturing. The conventional methods for processing of biomedical devices including freeze casting and sintering are limited because of the difficulties in adaptation at the host site and difference in the micro/macrostructure, mechanical, and physical properties with the host tissue. In this regard, EBM has a unique advantage of processing patient-specific complex designs, which can be either obtained from the computed tomography (CT) scan of the defect site or through a computeraided design (CAD) program. This review introduces and summarizes the evolution and underlying reasons that have motivated 3D printing of scaffolds for tissue regeneration. The overview comprises of two parts for obtaining ultimate functionalities. The first part focuses on obtaining the ultimate functionalities in terms of mechanical properties of 3D titanium alloy scaffolds fabricated by EBM with different characteristics based on design, unit cell, processing parameters, scan speed, porosity, and heat treatment. The second part focuses on the advancement of enhancing biological responses of these 3D scaffolds and the influence of surface modification on cell-material interactions. The overview concludes with a discussion on the clinical trials of these 3D porous scaffolds illustrating their potential in meeting the current needs of the biomedical industry.

“…As it is known that titanium dental implant surface is a multidimensional, and can be grouped according to their surface geometrical characteristics in macro, micro, nanometer scales. For long term osseointegration submicron surface properties were assumed to be the most effective parameter [11].…”

Abstract. Foreign substances and organic tissue interaction placed into the jaw in order to eliminate tooth loss involves a highly complex process. Many biological reactions take place as well as the biomechanical forces that influence this formation. Osseointegration denotes to the direct structural and functional association between the living bone and the load-bearing artificial implant's surface. Taking into consideration of the requirements in the manufacturing processes of the implants, surface characterizations with high precise measurement techniques are investigated and thus long-term success of dental implant is emphasized on the importance of these processes in this study. In this research, the detailed surface characterization was performed to identify the dependence of the manufacturing techniques on the surface properties by using the image processing methods and using the scanning electron microscope (SEM) for morphological properties in 3D and Taylor Hobson stylus profilometer for roughness properties in 2D. Three implant surfaces fabricated by different manufacturing techniques were inspected, and a machined surface was included into the study as a reference specimen. The results indicated that different surface treatments were strongly influenced surface morphology. Thus 2D and 3D precise inspection techniques were highlighted on the importance for surface characterization. Different image analyses techniques such as Dark-light technique were used to verify the surface measurement results. The computational phase was performed using image processing toolbox in Matlab with precise evaluation of the roughness for the implant surfaces. The relationship between the number of black and white pixels and surface roughness is presented. FFT image processing and analyses results explicitly imply that the technique is useful in the determination of surface roughness. The results showed that the number of black pixels in the image increases with increase in surface roughness.
