抄録

In this study, a new analyzing system was developed to evaluate the facial appearance of denture wearers affected by inadequate dentures and aging. In this system, the frontal and lateral digital facial images captured using a digital camera were displayed on a computer monitor and were analyzed according to the linear and angular measurements by image analysis software.<BR>This system required a short time to complete the analysis, and showed high reliability because the dimensional error on image distortion and difference of lens-subject distance was small. The facial images of 59 dentulous subjects (44 males and 15 females aged 23 to 29 years) were analyzed. Furthermore, this system and a polygon (a standard deviation diagram) from the data on the male dentulous subjects were applied to the analysis of the facial appearance of a denture wearer (78-year-old male).<BR>Dentures were useful to obtain lip support, but the effect of denture wearing was different for the analytical items. It was speculated that the differences in measurements between the edentulous subject with dentures and dentulous subjects were caused by aging and/or features of each edentulous subject.<BR>This system could be useful for routine clinical use in prosthetic dentistry.
