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

Table 1

Mean overjet and overbite of cast model and 2 digital models (mm).

Measurement	Cast (C)	Cast scan (CS)	Intraoral scan (IS)	Mean deviation/
	(mean ± SD)	(mean ± SD)	(mean ± SD)	standard error ( value)
Overbite	0.73 ± 2.11	0.74 ± 2.01	0.77 ± 2.06	C-CS	−.01/.33 (1.00)
				C-IS	−.04/.09 (1.00)
				CS-IS	−.04/.33 (1.00)
Overjet	2.69 ± 2.87	2.59 ± 2.75	2.62 ± 2.79	C-CS	.11/.38 (1.00)
				C-IS	.07/.08 (1.00)
				CS-IS	−.04/.36 (1.00)

values were calculated by RM-ANOVA.
