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

Table 5

Effect of severity of crowding on the dental measurements in the three dental models.

Measurement	Maxilla ( value)	Mandible ( value)
Mesiodistal width of central incisor	0.49	0.51
Mesiodistal width of lateral incisor	0.27	0.85
Mesiodistal width of canine	0.66	0.85
Mesiodistal width of first premolar	0.64	0.59
Mesiodistal width of second premolar	0.70	0.27
Mesiodistal width of first molar	0.96	0.62
Posterior sectional arch length	0.66	0.59
Anterior sectional arch length	0.80	0.82
Crowding	0.67	0.75

Mesiodistal width of teeth, = 40; posterior sectional arch length, anterior sectional arch length, and crowding, = 20; values were calculated by RM-ANOVA with Greenhouse-Geisser correction.
