The following is a summary of “Examination of facial measurement on the image using a noncontact three-dimensional measurement device,” published in the December 2022 issue of Primary care by Watarai, et al.
Improving the quality of life for older people who are edentulous requires making dentures. One of the crucial elements for a comfortable fit with dentures is the measurement of the occlusal vertical dimension while making dentures. For a study, researchers sought to evaluate the usefulness of determining the occlusal vertical dimension of a face measuring method applied to the scanned facial images using a noncontact three-dimensional measurement instrument.
In the study, the twenty-four dentulous subjects (mean age 26.6±2.4 years) were evaluated. While the face was held in hand and when it was fixed to the camera stand, non-contact three-dimensional measurement equipment was employed to scan the face. In the scanned face image, the distances between the subnasal and gnathion, the pupil and oral slit, the middle of the glabella and the subnasal, and the right and left corners of the mouth were measured and compared with the real values.
On the four measurement items, the considerable discrepancies between the distance between actual values and those produced from scanned data were not detected (fixing conditions). The distances between the subnasal and gnathion, the pupil, and the oral slit’s coefficients of variation on the scanned data (fixing condition) were substantially less than those under the real conditions (P< 0.05).
The investigation findings revealed that noncontact, three-dimensional measurement equipment may be used to successfully perform a reliable facial assessment. Results from the methodology were consistent with the real numbers.
