    The present study evaluated the reproducibility of the upper central incisor (ICS) position, with and without the head's frontal plane indicator device, by orthodontists using the 6 elements of Andrews in 2016. The type and level of the research was prospective, longitudinal, and descriptive observational. The sample consisted of 29 orthodontists trained in the 6 elements philosophy, who took measurements at two times, with a 3-month interval between T1 and T2, with and without the frontal plane indicator device. At T1, using the device, a mean of -0.05mm (SD 2.69) was obtained, with statistically significant differences (p=0.04); and without the device, a mean of 2.62mm (SD 1.41) was found, with statistically significant differences (p=0.00). At T2, using the device, a mean of -1.55mm (SD 2.85) was obtained, with statistically significant differences (p=0.00); and without the device, a mean of 1.07mm (SD 1.65) was found, with no statistically significant differences (p=0.82). Both evaluated with a Gold Standard with a mean of 1mm (SD 1). The average over time with the device at T1 was statistically equal to the average at T2 (p=0.048). The study concluded that the greatest reproducibility is achieved using the Head's Frontal Plane Indicator Device.
