Abstract		Background: Many orthodontic abnormalities appear as morphological abnormalities of the face, and the most disturbing to the observer is the asymmetry of the face. The diagnostics of facial abnormalities rely on the analysis of standardised photographs. Analysis of facial photographs is an important diagnostic tool, but unfortunately it shows a three-dimensional object in two dimensions. Subjects and methods: A total of 80 adults, 40 females (= 22.9 years, SD±1.4 years) and 40 males (= 23.1 years, SD±1.6 years), were selected for the study. The laser-scanned system that we used was composed of two Minolta Vivid VI900 optical laser-scanning devices assembled as a stereo pair connected to a 2GHz Pentium 4 processor. Results: The average Slovenian male and female face at the mean age of 22 years was constructed. The mean difference between the male and female facial templates was 0.98 ` 0.60 mm. The areas of the greatest deviation were the zygomatic area, the lower jaw line and the eyebrow area. Differences between the groups were analysed using the Student's t test and p values < 0.05 were considered significant. Conclusions: Our hypothesis was confirmed by the construction of the average face. The evolution of the laser-scanned system has brought a new, more objective approach to the diagnosis of facial asymmetry, which is a useful method for the comparison of craniofacial anomalies. It is a precious tool that allows following facial changes due to growth and treatment methods.
