Reliable Reference Areas for Three-dimensional Smiling Facial Model Alignments: Posed Versus Natural Smile Expressions.
The International journal of prosthodontics(2023)
Abstract
The findings of this study suggested that the reference surface areas and smiling types have some impacts on the accuracy of 3D smiling facial image alignments. Large and evenly distributed matching surfaces are recommended for posed smiles; whereas caution should be taken when using the chin area as a reference surface for matching natural smile facial images.
