Upper lip elevation in autonomous maximal smile: A three-dimensional facial imaging study
Key Points
This research aims to measure upper lip elevation during maximal smiles across different sex and age groups.
Used three-dimensional imaging to capture upper lip metrics.
Measured ULL, ULL@AMS, and ULE during maximal smile.
Analyzed data across different sex and age demographics.
Established preliminary normative values for upper lip elevation metrics.
Found variations in measurements based on sex and age.
Provided insights that can guide orthodontic treatment and aesthetic procedures.
Abstract
ULL, ULL@AMS and ULE in AMS were precisely measured using 3D imaging across different sex and age groups, offering preliminary normative references for related orthodontic treatment and esthetic procedures.
