Findings on Bone Research Detailed by Researchers at Hokkaido University (Irradiation conditions for fiber laser bonding of HAp-glass ceramics with bovine cortical bone)

By a News Reporter-Staff News Editor at Biotech Week -- A new study on Bone Research is now available. According to news reporting out of Sapporo, Japan, by NewsRx editors, research stated, "Orthopedic implants are widely used to repair bones and to replace articulating joint surfaces. It is important to develop an instantaneous technique for the direct bonding of bone and implant materials."

Our news journalists obtained a quote from the research from Hokkaido University, "The aim of this study was to develop a technique for the laser bonding of bone with an implant material like ceramics. Ceramic specimens (10 mm diameter and 1 mm thickness) were sintered with hydroxyapatite and MgO-Al2O3-SiO2 glass powders mixed in 40:60 wt% proportions. A small hole was bored at the center of a ceramic specimen. The ceramic specimen was positioned onto a bovine bone specimen and a 5 mm diameter area of the ceramic specimen was irradiated using a fiber laser beam (1070-1080 nm wavelength). As a result, the bone and the ceramic specimens bonded strongly under the irradiation conditions of a 400 W laser power and a 1.0 s exposure time. The maximum shear strength was 5.3 2.3 N. A bonding substance that penetrated deeply into the bone specimen was generated around the hole in the ceramic specimen. On using the fiber laser, the ceramic specimen instantaneously bonded to the bone specimen."

According to the news editors, the research concluded: "Further, the irradiation conditions required for the bonding were investigated."
