Model Analysis of Digital Models in Moderate to Severe Crowding: In Vivo Validation and Clinical Application

Figure 2

Comparison of intraoral scan model and real dentition. (a) Intraoral-scan model and intraoral photo of mild crowding. (b) Intraoral-scan model and intraoral photo of severe crowding. The proximal surface of the tooth is reproduced with acceptable quality in both mild and severe crowding; in some cases, it was easier to measure the mesiodistal width of posterior tooth in the severe crowding model than in the mild crowding model because of exposure of measuring points from posterior crowding.
