摘要: Abstract Aim To evaluate time, reliability and accuracy of craniofacial measurements with a 3D light scanner, considering prior demarcation surface points on the face. Materials methods Eleven facial 15 volunteers were obtained by scanner (Artec Eva TM) caliper directly face, or without reference points. Inter intra-method comparison examined intraclass correlation coefficient analysis random error Dahlberg formula. Agreement between was analyzed Bland-Altman. A Wilcoxon test used to compare time for each method, at p Results Marking face improved both methods. In inter-methods landmarks, showed excellent in all measures (ICC = 0.92–0.97, Conclusions Craniofacial accuracy, which qualifies this method clinical scientific use. Accuracy is when previously marked However, needed obtain greater than about 4 min direct method.
