Introduction: The purpose of this study was to evaluate the agreement between the predicted and the achieved tooth position planned
by an orthodontic digital system. Methods: Digital models of the setup (Predicted) and the treated (Treated) groups of 23 subjects with
Class I malocclusion were obtained. Digital models (Predicted and
Treated) of each patient were superimposed, and referential geometric
planes were constructed for linear and angular measurements: arch
perimeter, arch depth, intercanine and intermolar widths, mesiodistal crown angulation, and buccolingual crown inclination. Bland-Altman analysis was performed to establish the agreement between the
measurements. Spearman’s correlation coefficient was used to evaluate the correlation between groups. Results: Compared to Predicted group, the Treated group presented larger linear measurements
for all measurements: 1) arch perimeter: 1.77±2.10 mm (maxilla) and
1.78±1.74 mm (mandible); 2) arch depth: 0.50±0.69 mm (maxilla) and
0.38±0.81 mm (mandible); 3) intercanine width: 0.30±0.98 mm (maxilla)
and 0.49±0.64 mm (mandible), and; 4) intermolar width: 0.70±1.63 mm
(maxilla) and 1.13±1.62 mm (mandible). Seven out of 14 angular measurements showed statistical differences between Predicted and Treated
groups in the maxilla, while six out of 14 angular measurements were
statistically significant between the two groups; the differences ranging from -8.91º to 1.91º and from -3.53° to 9.59° in the maxilla and mandible, respectively. Conclusions: The agreement between the Predicted and Treated groups was majority within the limits. The predictions
of the digital system were not accurate in some parameters; however,
most of the differences were within clinical acceptable range. Although
there are some inaccuracies, the limitations do not seem to interfere
with clinical outcomes and the quality of the treatment.
