Fig. 2From: Intermittent parathyroid hormone (PTH) promotes cementogenesis and alleviates the catabolic effects of mechanical strain in cementoblastsComponents and schematic diagram of the uniaxial four-point bending system. The uniaxial four-point bending system is made up of a a digital control unit, b bending boxes and c an actuator. d Schematic diagram illustrates how the four-point bending unit works. When the bending box is compressed by the actuator, the cell culture plate is bended by four points to generate tensile strainBack to article page
