There are many possibilities for the use of three-dimensional (3D) scanners in maxillofacial surgery. This study aimed to investigate whether the bundling and syncing of two 3D scanners has advantages over single-scanner acquisition in terms of scan quality and the time required to scan an object.Therefore, the speed and precision of 3D data acquisition with one scanner versus two synced scanners was measured in 30 subjects. This was done by analyzing the results obtained by scanning test objects attached to the forehead and cheeks of the subjects. Statistical methods included the Student t test for paired samples.Single-scanner recording resulted in significantly lower mean error of measurement than synced recording with two scanners for length (P &lt; 0.001), all frontal/lateral plane angles (P = 0.034, P &lt; 0.001, P = 0.002, P = 0.003), and side/side plane angles (P = 0.014, P &lt; 0.001, P = 0.015, P = 0.011) of the test object on the cheek. Likewise, the single-scanner method resulted in a significantly lower mean error of measurement than the two-scanner method for frontal/lower plane angles (P &lt; 0.001), right/lower plane angles (P &lt; 0.001), and left/lower plane angles (P = 0.002). Conversely, synced recording of data with two scanners resulted in a significant reduction of scanning time (P &lt; 0.001).Compared to data acquisition with a single 3D scanner, the bundling of two 3D scanners resulted in faster scanning times but lower scan quality
