Intended use: • Torque ratchet for the screwing in and loosening screws with a described torque characteristic in the dental field. In a blocked role it is feasible to switch major torques, which are wished e.g. to screw in implants or to loosen screwed joints. • The torque ratchet is to be used only with the aid of dentally trained ...
Firm and immediate fixation between pedicle screws and bone prevents aseptic loosening and implant failure. Coating with hydroxyapatite is a possible method to improve the fixation of metallic implants in bone. ...
Mixing techniques used to reduce porosity in bone cement demonstrate large improvements in fatigue behaviour in test specimens, but do not appear to reduce the rate of loosening of implants in vivo. We examined data showing the effect of notches on fatigue strength and found, surprisingly, that notches with low stress-concentration factors (Kt Keywords: mixing ...
