Accuracy of tooth movements

Movement	Mean accuracy (%)	Highest accuracy (%)	Lowest accuracy (%)	Standard deviation	p-value
Premolar Derotation w Att	37.5	80.6	- 2.9	0.3	0.00
Premolar Derotation w/o Att	42.4	79.8	23.6	0.3	0.02
Distalization w Att	88.4	108.7	56.4	0.2	0.38
Distalization w/o Att	86.9	104.2	61.0	0.2	0.46
Incisor Torque w Att	49.1	71.6	29.9	0.2	0.00
Incisor Torque w PR	51.5	75.1	27.4	0.2	0.00

w Att. = with Attachment; w/o Att. = without Attachment; w PR = with Power Ridge.

p-value = clinically achieved tooth movement (T2) – tooth movement predicted by ClinCheck (Clin T2), p < 0.05.
