Precision in Facial Measurements: Comparative Analysis Between a Digital 3D Scanner and an Analog Instrument.

ABSTRACT: Background: Accurate facial proportion analysis is essential for therapeutic planning in dentistry. This study aimed to evaluate the Planmeca ProFace 3D scanner's accuracy by comparing its digital measurements to analog caliper measurements. Methods: A comparative cross-sectional study included seven patients. Fourteen standardized facial landmarks were measured digitally and with an analog caliper. Distances were grouped as small (≤6.5 cm, Group A) or large (>6.5 cm, Group B). Paired t-tests, Cronbach's Alpha, and Bland-Altman analysis assessed differences, reliability, and agreement. Results: The results showed a statistically significant difference between the two methods of measurements in group A (p = 0.016) and high statistical significance was obta
