Primary Outcome Measures

Name	Time	Method
Accuracy measured by analyzing linear and angular deviations between each test scan and the reference scan using a dedicated measurement software (Hyper Cad S, Cam HyperMill, Open Mind Technologies, Milano, Italy)

Secondary Outcome Measures

Name	Time	Method
The effect of stereophotogrammetry versus IOS, adjusting for possible confounding factors, will be measured using the General Linear Model at multivariate analysis
