CARRERO TORO, Wilmer A et al. Design and manufacturing of a load-cell for physiological measuring in alveolar distraction. Acta odontol. venez [online]. 2009, vol.47, n.4, pp.56-68. ISSN 0001-6365.

A key aspect involved in the mechanical design of alveolar distractor is the accurate evaluation of physiological loading for computer simulation. Very few information and previous work are available about this subject. A stainless steel load cell having strain gauges has been developed and manufactured. This cell was attached to a splint, like those used in orthodontia. The load cell was calibrated and then an “in vivo” test was carried out on a partially-edentulous patient. Digital registers of load were obtained for three cases: tongue protrusion, lower lips retraction and a combination of both
