For each subject’s deal with was filed once having good step three-D cam (3dMDcranial Program, 3dMD, Atlanta, GA, USA) having a-1.5-ms take price and you will an excellent dimensional precision off 0.2 mm 21 .
For each three dimensional face image, scaled down so you can 75% of the real dimensions, was demonstrated to your a great 17-during the Lcd screen (1701FP, Dell, Inc., Round Rock, Tx, USA).

An earlier research 21 you to examined the fresh intra-observer accuracy confirmed an indicate absolute landmark improvement from 0.thirty two mm (variety, 0.07 so you can 0.52 mm) within frequent procedures (Second Text S2).
