“…Nonetheless, one must consider that the used structures, such as the maxilla with dental wax and metal teeth, do not show the behaviour of dental structures and the complex nature of the PDL. According to Yoshida et al [15] and Aschero et al [16], it is not possible to reproduce the physiological response of the PDL at the moment of the application of the force in artificial systems. This study simply provides a technique for the acquisition of force values similar to those forces dissipated during the appliance activation, in a way that it be used in the future in orthodontic treatments.…”

HiBi FBG are used to demonstrate a technique to evaluate orthodontic forces. The experiments are performed in an artificial maxilla supporting dental wax and metal teeth. The teeth are instrumented using an orthodontic technique and loads are applied representing auxiliary appliance. The values of the loads (extra-oral) are based on clinical applications. It is demonstrated that the tooth vestibular surface is subject to a force of 0.13 N. The size and sensitivity of the FBG allow for the determination of forces applied orthogonally to the surface of the teeth.

“…In addition to the normal physiological variability among animals and species, variance might arise from unreported experimental errors, from the different techniques for preparing the samples, or from repeated measurements on the same sample. Indeed, bone sample physical properties may alter irreversibly due to changes in temperature, moisture content, or to drying and re-wetting (Reinish and Nowick 1975;Bur 1976;Aschero et al 1999). Roughly summarizing, the piezoelectricity in bone decreases as the water content increases.…”

This paper presents a theoretical investigation of the multiphysical phenomena that govern cortical bone behaviour. Taking into account the piezoelectricity of the collagen-apatite matrix and the electrokinetics governing the interstitial fluid movement, we adopt a multiscale approach to derive a coupled poroelastic model of cortical tissue. Following how the phenomena propagate from the microscale to the tissue scale, we are able to determine the nature of macroscopically observed electric phenomena in bone.

“…Based on the concept of converse piezoelectric effect (Qin, 2001), the piezoelectric coefficient d 23 was determined using a sensitive dilatometer (Aschero et al, 1999). Piezoelectric force microscope and atomic force microscope were also employed to measure piezoelectric properties of bone (Kalinin et al, 2005;Minary-Jolandan and Yu, 2009).…”

a b s t r a c tAn exponential law is presented for modeling piezoelectric behavior of bone tissues. The law is established based on experimental observation and existing empirical decay function. The model is then used to investigate the relaxation behavior of pizeovoltages induced by external load. Piezovoltages between the two opposing surfaces of bovine tibia bone samples under three point bending deformation are measured using an ultra high input impedance bioamplifier. The experimental results indicate that the pizeovoltages of bone show different relaxation behaviors during loading and unloading process. It is found that the piezovoltage decay follows a stretched exponential law when the load increases from zero to its maximum value, while it follows a typical relaxation exponential law when the load is kept its maximum value. The stretching-exponential behavior is independent of loading amplitude and rate. One possible reason for causing the stretched exponential behavior may be due to the triple helices structure of collagen fibrils distributed randomly in bone, which can experience relatively large deformation under external loads. The deformation process may include self-deformation and relative slipping between the molecule chains. The relative slipping movements may change the dielectric constants and resistances of bone, which can lead to multiple relaxation time behaviors during the deformation process of bone.
