ORTHODONTICS AND CRANIOFACIAL RESEARCH

  • The purpose of this study was to estimate a range of acceptable appearances for selected facial features and refine techniques for measurement. A psychophysical method was administered using photocopies of altered facial photographs to measure tolerances for deviations in eye position and mouth angulations and judges’ reaction time( 76 individuals). The results showed tolerance for deviation of facial appearance varies inversely with the magnitude of the physical deviations from normal. Tolerance varies directly as a function of assumed familiarity with deviation. Response and reaction time varied inversely with the tolerance for facial deviation.

  • A rat model of orthodontic tooth movement was used to support the premise that pdl cells experience plasma membrane disruption and resealing events upon application of mechanical stress.
  • These studies provided evidence of a novel cellular mechanism for uptake and release of molecules and suggest a potential role for plasma membrane disruption in the mechanotransduction of orthodontic tooth movement.
