- Primary Outcome Measures
Name Time Method Scanning sequences can affect palatal trueness of intraoral digital models. By a modified regional model superimposition, the 3D measurements of palatal trueness in Intraoral scanning Groups, in which intraoral scanning sequences over palatal region were different, were slightly statistically significant.
- Secondary Outcome Measures
