3D - Sense reliability and reproducibility. Accuracy evaluation of extraoral 3D facial scanning

Abstract: Aim: The aim of this study was to validate the 3D Sense scanner to evaluate its accuracy and eventual use in odontology. Method: In this study, a model of a head was created with anthropometric landmarks. The 3D Sense scanner was used for examinations of distances and angle accuracy. The results of the 3D Sense scan were then compared to a reference master model to get the standard deviation and reliability of the 3D Sense scanner. Results: The 3D Sense scanner showed a varying accuracy depending on the positioning and distance between the measuring points on the model. The best perception of the 3D Sense proved to be when the scanner was held still in a static position. The more movement of the scanner, the less accurate result. Conclusion: The present 3D scan analysis of 3D Sense proved overall a good reliability and reproducibility. To implement the 3D Sense scanner in odontological treatment, further studies are needed with refined technique in order to get all of the measurement accurate.
