    Objectives The development of 3D photography systems allows surgeons a radiation-free registration of the face. Those 3DScans can improve the planning and documentation of Facial plastic surgery. The question of whether the accuracy and precision of the different 3D image acquisition systems differ from one another is of high importance. Inexpensive devices such as the smartphone can be useful if they are sufficiently accurate.

    Material and methods To determine the accuracy and precision of the various 3D photography systems, we created 3D scans of 20 healthy volunteers using (a) Artec​ Space Spider (b) Densply Sirona Planmeca and (c) iPhoneXR using Bellus 3D​ application. As reference, we digitalized a plaster model of the nose .All resulting standard tesselation language (.stl) files of the noses were compared to the original, virtual .stl files of the digitalized plaster model. The root mean square error (RMSE) was calculated for each surface (Artec Studio 13 Professional × 64; Artec​ Group; Luxembourg) to determine which 3D scan shows the highest accuracy.

    Results The Wilcoxon signed-rank test was used. The Artec Space Spider scans significantly showed the best RSME analysis, better than the Densply Sirona Planmeca and the Bellus 3D application (p = 0,018). There is no significant difference between the Densply Sirona Planmeca and the Bellus 3D​ application (p= 0,176).

    Conclusion The study provides a comparison of the accuarcy of three different 3D photography systems. Nose scans using Artec​ Space Spider showed the highest precision and accuracy. However it is foreseeable that compact, handheld mobile device solutions are promising alternatives .Therefore an appropriate balance between the clinical needs and the technical opportunities must be found.
