Journal ArticleDOI
Novel bioactive materials with different mechanical properties.
TL;DR: The biomimetic process has been used to deposit nano-sized bone- like apatite on fine polymer fibers, which were textured into a three-dimensional knit framework, which is expected to ultimately lead to bioactive composites that have a bone-like structure and, hence,Bone-like mechanical properties.
Journal ArticleDOI
Antibacterial silver-containing silica glass prepared by sol-gel method.
Masakazu Kawashita,S Tsuneyama,Fumiaki Miyaji,Tadashi Kokubo,Hiromitsu Kozuka,Kazumasa Yamamoto +5 more
TL;DR: The sol-gel derived silica glass powders containing silver with compositions Al/Ag > or = 1 are believed to be useful as an antibacterial material for medical applications such as filler of composite resin for dental restoration.
Journal ArticleDOI
Bioactive metals: preparation and properties.
TL;DR: Some ceramics, such as Bioglass®, sintered hydroxyapatite, and glass-ceramic A-W, spontaneously form a bone-like apatite layer on their surface in the living body, and bond to bone through the apatites, and are clinically important for use as bone-repairing materials.
Journal ArticleDOI
The mechanism of biomineralization of bone-like apatite on synthetic hydroxyapatite: an in vitro assessment
TL;DR: The mechanism of biomineralization of bone-like apatite on synthetic hydroxyapatite (HA) has been investigated in vitro, in which the HA surface was surveyed as a function of soaking time in simulated body fluid (SBF), and analysis indicated that, immediately after immersion in SBF, the HA revealed a highly negative surface potential.
Journal ArticleDOI
Preparation of bioactive titania films on titanium metal via anodic oxidation.
Xinyu Cui,Hyun Min Kim,Masakazu Kawashita,Longbao Wang,Tian Ying Xiong,Tadashi Kokubo,Takashi Nakamura +6 more
TL;DR: The resultant apatite layer formed on titanium metal in SBF could enhance the bonding strength between living tissue and the implant and be an effective method for preparing bioactive titanium metal as an artificial bone substitute even under load-bearing conditions.
