Abstract: An intraoral scanning system for scanning an intraoral dental structure of a patient in a dental procedure may include an intraoral scanner and one or more processors coupled to the intraoral scanner and programmed with instructions that when executed by the one or more processors cause the intraoral scanning system to build a 3D model of the intraoral dental structure of the patient based on scan data acquired via the intraoral scanner and output feedback on a display. The feedback may include highlighting a portion of the 3D model that includes scan data that includes a finish line of the intraoral dental structure, wherein the scan indicates that the finish line is not suitable for receiving a prosthetic.

Abstract: A processor receives first intraoral scan data comprising a first depiction of a dental site; generates a virtual three-dimensional (3D) model of the dental site using the first intraoral scan data; and processes at least one of the first intraoral scan data or data from the virtual 3D model to identify an unclear feature. The processor outputs instructions to generate second intraoral scan data of the dental site depicting the portion of the dental site that is unclear; receives the second intraoral scan data; and updates the virtual 3D model of the dental site using the second intraoral scan data, wherein the portion of the dental site that was unclear in the virtual 3D model is replaced with information from the second intraoral scan data.

Abstract: A method of fabricating a dental appliance includes receiving a digital three-dimensional model of a mold for a dental arch of a patient, the digital three-dimensional model of the mold comprising one or more features associated with a cut line. The method further includes fabricating the mold by a rapid prototyping machine using the digital three-dimensional model, the mold having the one or more features. The method further includes thermoforming the dental appliance over the mold, wherein the one or more features cause the dental appliance to have one or more markings or elements for the cut line. The method further includes removing the dental appliance from the mold, and trimming the dental appliance along the cut line using the one or more markings or elements.
