A computing device implemented method of virtual cephalometric imaging, comprising: creating a first 3D virtual model and a second 3D virtual model of a patient's dentition, wherein the first 3D virtual model is based on a first impression taken of the patient's dentition at a first time and the second 3D virtual model is based on a second impression taken of the patient's dentition at a second time; correlating the first and the second 3D virtual models; generating a 2D image including a first outline representing a position of at least one tooth of the patient's dentition according to the first 3D virtual model and a second outline representing a position of the at least one tooth according to the second 3D virtual model; wherein generating the 2D image includes positioning the first outline relative to the second outline according to the correlation of the first and the second 3D virtual models, wherein correlating includes applying at least one geometric transformation to the first 3D virtual model to superimpose the one or more 3D virtual soft tissue portions of the first 3D virtual model with the one or more 3D virtual soft tissue portions of the second 3D virtual model, and wherein respective virtual models include respective points (322A, 322B) and said superimposition incudes establishing a relative position where a greatest percentage of a first number of points relative to said first 3D virtual model spatially matches corresponding points of said second 3D virtual model, and wherein correlating further includes: assigning a lower weight superimposition metric to a first 3D virtual soft tissue portion that is proximal to at least one of the one or more individual 3D virtual teeth; assigning a higher weight superimposition metric to a second 3D virtual soft tissue portion that is distal to the at least one of the one or more individual 3D virtual teeth; resolving a divergent superimposition result of the at least one geometric transformation between the first and the second 3D virtual soft tissue portions in favor of the second 3D virtual soft tissue portion having the higher weight superimposition metric assigned thereto. creating a first 3D virtual model and a second 3D virtual model of a patient's dentition, wherein the first 3D virtual model is based on a first impression taken of the patient's dentition at a first time and the second 3D virtual model is based on a second impression taken of the patient's dentition at a second time; correlating the first and the second 3D virtual models; generating a 2D image including a first outline representing a position of at least one tooth of the patient's dentition according to the first 3D virtual model and a second outline representing a position of the at least one tooth according to the second 3D virtual model; wherein generating the 2D image includes positioning the first outline relative to the second outline according to the correlation of the first and the second 3D virtual models, wherein correlating includes applying at least one geometric transformation to the first 3D virtual model to superimpose the one or more 3D virtual soft tissue portions of the first 3D virtual model with the one or more 3D virtual soft tissue portions of the second 3D virtual model, and wherein respective virtual models include respective points (322A, 322B) and said superimposition incudes establishing a relative position where a greatest percentage of a first number of points relative to said first 3D virtual model spatially matches corresponding points of said second 3D virtual model, and wherein correlating further includes: assigning a lower weight superimposition metric to a first 3D virtual soft tissue portion that is proximal to at least one of the one or more individual 3D virtual teeth; assigning a higher weight superimposition metric to a second 3D virtual soft tissue portion that is distal to the at least one of the one or more individual 3D virtual teeth; resolving a divergent superimposition result of the at least one geometric transformation between the first and the second 3D virtual soft tissue portions in favor of the second 3D virtual soft tissue portion having the higher weight superimposition metric assigned thereto. assigning a lower weight superimposition metric to a first 3D virtual soft tissue portion that is proximal to at least one of the one or more individual 3D virtual teeth; assigning a higher weight superimposition metric to a second 3D virtual soft tissue portion that is distal to the at least one of the one or more individual 3D virtual teeth; resolving a divergent superimposition result of the at least one geometric transformation between the first and the second 3D virtual soft tissue portions in favor of the second 3D virtual soft tissue portion having the higher weight superimposition metric assigned thereto.
