All reviewed studies confirmed feasibility of integrating intraoral scans with 3D facial images. The QUADAS-2 assessment revealed a high risk of bias for all included studies. Certainty of evidence concerning the accuracy was very low (GRADE). Due to heterogeneity concerning registration procedures and anatomical landmarks between the included studies, a qualitative description analysis of the results was made.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The accuracy of the registration of a digital dental cast or intraoral scan into a facial scan is clinically acceptable. Most, but not all outcomes met the 2\u2005mm or 2 degree threshold, depending on anatomical region, image acquisition, and measurement method. A 3D image of the face with an integrated digital dental cast or intraoral scan may be a promising radiation-free method for orthodontic diagnostics and treatment planning. However, due to the inconsistency in different registration methods and small sample sizes, the accuracy is yet to be further investigated.<\/jats:p>\n                  <\/jats:sec>\n
