Novel fabrication of porous titanium by a resin-impregnated titanium substitution technique for bone reconstruction

Abstract

The purpose of this study was to evaluate the characteristic structures and osteoconduction ability of porous titanium structures using a resin-impregnated titanium substitution fabrication technique.

The development of novel bioactive porous titanium as a bone reconstruction material

“…We speculated that similar bone formation in the marginal portion was due to osteoconduction from the surrounding bone tissues. 8,9 In 2 weeks, both groups indicated bone formation at the marginal portion. However, only ATPT enabled bone formation in the central portion.…”

“…Samples of porous titanium, with 85% interconnected porous structures, were fabricated using a resinimpregnated titanium substitution method, as described previously. 9 The surface treatment process was as per our previous study. 16,19 For non-treated porous titanium (control), samples were washed with an ultrasonic cleaner using acetone and distilled water for 1 h each and dried overnight in a 37 C oven (Fig.…”

“…We have previously reported a novel porous titanium fabrication method called the resin-impregnated titanium substitution technique; using this technique, we fabricated porous titanium with a similar structure to that of urethane form as base material. 9 We have successfully used this method to fabricate 65-85% porous titanium with good mechanical strength and osteoconductivity. Using this process, we can fabricate the same structure of titanium as that in a base urethane form.…”

Comparative Study of Surface Modification Treatment for Porous Titanium

“…Twenty-seven porous shaped pure titanium (porous titanium, purity 99.7%) disk types (diameter 13 mm × thickness 2 mm, 85% porosity) were used for surface modification (Figure 1). Porous titanium samples were fabricated using a resin-impregnated titanium substitution technique [17]; the base urethane foam was soaked into the slurry with pure titanium powders, and heat to eliminate urethane before be sintering. The surface treatment was performed as follows.…”

Biofunctionalization of Porous Ti Substrates Coated with Ag Nanoparticles for Potential Antibacterial Behavior

“…In this sense, the use of porous Ti has been widely investigated as a potential solution to reduce stress-shielding issues [10][11][12][13]. Different techniques to fabricate these types of porous materials have been reported in the literature, such as powder metallurgy, foaming technologies, and additive manufacturing methods [14][15][16][17][18][19][20][21][22]. In addition, the potential use of β-Ti alloys has been explored to minimize the stress-shielding issues [23].…”
