Simultaneous, radiation-free registration of the dentoalveolar position and the face by combining 3D photography with a portable scanner and impression-taking

Abstract: ObjectivesSimultaneous, radiation-free registration of the teeth and the upper and lower jaw positions in relation to the extraoral soft tissue could improve treatment planning and documentation. The purpose of this study is to describe a workflow to solve this form of registration and surface acquisition with a mobile device.MethodsFacial scans of ten healthy participants were taken using a blue-light LED 3D scanner (Artec® Space Spider; Artec® Group; Luxembourg). An impression of the maxillary dentoalveolar … Show more

“…Therefore, the first null hypothesis, namely that the use of extraoral markers would not affect the accuracy of 3D dentofacial integration, was rejected. The results corresponded well with those of a previous study [ 32 ], in which the use of extraoral markers was an effective and accurate method for dentofacial model registration. Due to the limitations in obtaining a 3D facial model with the clear appearance of dentition, the use of extraoral markers has been suggested to enhance the accuracy of integration between facial models and digital dental models [ 20 , 25 , 26 ].…”

“…The use of 3D scanning has recently been investigated regarding its usefulness for the documentation of body shape in bariatric surgery [1]. It is also being used for ever more complex tasks in maxillofacial surgery [2] and is finding application for augmented reality and virtual reality [3]. Clinicians of a growing number of medical disciplines effectively apply this radiation-free and cost-efficient technology to monitor specific anatomical regions, such as the breast [4,5], face [6,7], or leg [7,8].…”

“…The root mean square error quantifies the deviation (ie, the absolute difference) between two 3D models. 1,2 The root mean square error was calculated with respect to the best rated 3D model. To demonstrate the transfer into practice, the proposed methodology was used to monitor a radial digital-nerve lesion of a right thumb with subsequent nerve coaptation in a single patient over a follow-up interval of 6 months.…”
