Method & Evidence

AimTo establish and evaluate a 3D virtual patient analysis workflow for dental esthetics, assessing its accuracy and reproducibility against 2D methods and direct measurements.

MethodExperimental study with a self-controlled experiment.

ProcedureA 3D esthetic analysis workflow was developed, involving key point detection, coordinate system redetermination, and esthetic parameter calculation. This workflow was then applied to 3D virtual patient models. The accuracy and reproducibility were assessed by comparing measurements from the 3D workflow, 2D analysis, and direct measurements, using paired t-tests to evaluate differences.
