| the authors confirm the hypothesis that all the NHP registration methods evaluated in this study do not present statistically significant differences (P>0.05) and consider that all head orientation technique can be helpful, accurate, and valid for the desired result for patients without significant symmetrical deviations. Therefore, it is needed to perform more studies with large asymmetrical patients, to confirm or not if any NHP registration method can always be used, without loss of precision for the virtual surgical planning. | — |
