A method for determining biting occlusion of a patient's teeth including generating a first 3D digital model of the patient's lower arch in non-occlusion. A second 3D digital model of the patient's upper arch in non-occlusion may be generated. A third 3D digital model of the patient's upper and lower arches in biting occlusion may be generated. The first and second 3D digital models May be aligned with corresponding teeth of the third 3D digital model to generate a fourth 3D model of the patient's teeth in biting occlusion.

A computer-implemented method of processing a digital dental impression includes determining one or more first digital surface regions visible from a first side of the digital dental impression along an occlusion axis and one or more second digital surface regions visible from a second side of the digital dental impression along the occlusion axis, segmenting the digital dental impression into one or more digital segments and determining the one or more digital segments as a first digital segment or a second digital segment based on the majority of digital surface regions in the one or more digital segments.

A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.
