Resumen

VILLANUEVA-BONILLA, Sebastián; SAAVEDRA-LAYERA, Loreto  y  VERGARA-NUNEZ, Cristian. Comparison of direct and 3D anthropometric measurements in young adults. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2018, vol.11, n.1, pp.16-19. ISSN 0719-0107.  http://dx.doi.org/10.4067/S0719-01072018000100016.

Objective:

The aim of this study was to determine if there is equivalence between facial measurements obtained through direct facial anthropometry and indirect facial anthropometry using a three-dimensional digital imaging system in young adults.

Materials and methods:

Descriptive cross-sectional study. The sample consisted of 81 volunteers (19-29 years). Each was measured with 6 facial distances with the direct anthropometric method and 5 facial distances with the 3D photogrammetric method. The programs Excel 2013 and Stata14® were used. The Shapiro-Wilk test was applied to establish the type of distribution of the data. For those with normal distribution, t-Test was applied; for those with non-normal distribution, a Mann-Whitney test was applied. The measurements obtained with both methods were compared.

Results:

We compared the 5 facial distances measured with the direct anthropometric method with the 5 recorded by 3D photogrammetry and it was determined that there is no statistically significant difference between the methods used. There was a measurement that could not be recorded with the 3D photogrammetric method.

Conclusion:

The indirect facial anthropometry measured in 3D images, provides measurements equivalent to direct facial anthropometry.
