Brief summary
The primary aim of the current study was to estimate the validity, reliability, and repeatability of LII measurements
Detailed description
the primary aim of the current study was to estimate the validity, reliability, and repeatability of LII measurements made directly on digital models compared to those made on traditional plaster models. As a secondary aim, the same comparisons will also performed between digital photographs of study models and their corresponding plaster models.
