    摘要： Systems, methods, and/or computer-readable media described herein provide technical solutions to the highly technical problems of machine generation of dental restorations. In particular, these systems, methods and/or computer readable media may provide technical solutions to aid in the creation of dental restorations that more closely resemble a natural tooth (including its internal optical structure). These systems, methods and/or computer readable media may help in virtually rendering a tooth, including its internal optical structure, and apply these renderings (e.g., digital models) to the fabrication of the dental restoration.

    摘要： A system includes an optical probe with a sensing face. The optical probe to emit optical signals and receive reflected optical signals. The system includes a computing device, coupled to the optical probe, to receive intraoral scan data of a tooth. The intraoral scan data includes first optical scan data and second optical scan data. The computing device to process the received intraoral scan data to adjust the first optical scan data associated with a sub-gingival surface of the tooth based on the second optical scan data associated with a material covering the sub-gingival surface of the tooth. The computing device to generate a three-dimensional model that includes the sub-gingival surface of the tooth using the adjusted first optical scan data that is associated with the sub-gingival surface of the tooth.

    摘要： Methods and systems are described that receive intraoral scan data in response to an optical scan of a surface of the tooth and a material disposed between the tooth and a gingiva surrounding the tooth, the material separating the surrounding gingiva from the tooth and covering a sub-gingival surface of the tooth. The received intraoral scan data is processed to differentiate the first optical scan data associated with the sub-gingival surface of the tooth and the second optical scan data associated with the material covering the sub-gingival surface of the tooth. The three-dimensional model of the tooth is generated based on the first optical scan data that is associated with the sub-gingival surface of the tooth and the third optical scan data associated with the tooth surface that is not covered by the material such that the three-dimensional model of the tooth includes the sub-gingival surface of the tooth.
