ABSTRACT
Background:
Producing dentures for edentulous patients is important to improve quality of life of elderly. The determination of the occlusal vertical dimension on producing dentures is one of the key factors for using the dentures comfortably. The purpose of this study is to consider the usefulness of the determination of the occlusal vertical dimension of a facial measurement method applied on scanned facial image using a noncontact three-dimensional measurement device. Materials andMethods:
Twenty-four dentulous individuals (mean age 26.6 ± 2.4 years old) were examined in this study. A noncontact three-dimensional measurement device was used for the scanning of the face both in the holding by hand and the fixing to the camera stands situations. The distances between subnasal and gnathion, pupil and oral slit, middle of glabella and subnasal, and right and left corners of the mouth were measured on the scanned face image and compared with the actual values.Results:
The significant differences were not recognized on the four measurement items between the distance of actual values and obtained on scanned data (fixing conditions). The coefficients of variation of the distances between subnasal and gnathion, and pupil and oral slit on scanned data (fixing condition) were significantly lower than those at actual conditions (P < 0.05).Conclusion:
The results of this study suggested that a stable facial measurement can be successfully implemented by using a noncontact three-dimensional measurement device. This method yields outcomes which match the actual values.
