Brief Summary

This study evaluates whether a 3D-printed extraoral camera assembly can improve the reproducibility and dimensional consistency of dental photographs compared with conventional DSLR methods. By standardizing camera position, distance, and angle, the assembly provides a non-contact, operator-independent approach to ensure consistent image geometry, supporting more accurate clinical records, esthetic documentation, and digital analyses.
