Abstract: A data generation program is configured to cause a computing device to display, on a display, an oral cavity image three-dimensionally showing an oral cavity including a biological tissue, set, in the oral cavity image, a first spot indicating a top of a crown portion, a second spot indicating a top of an alveolar bone or a junction between a tooth and a gingiva, and a third spot indicating a root apex portion based on a user input or machine learning, and calculate a ratio between a first distance between the first spot and the second spot and a second distance between the second spot and the third spot.

Abstract: A jaw movement analysis system includes circuitry that is configured to acquire chewing information including time-series information that represents a jaw movement of a user chewing a bite of food, and to determine an attribute of the food having been chewed by the user based on the chewing information acquired and based on an analysis model. The analysis model is generated by machine learning based on training data including first information that includes time-series information indicating a past jaw movement during a chewing of a bite of food, and second information that indicates an attribute of the food chewed during the past jaw movement associated with the first information.

Abstract: A data processing apparatus includes: an input portion configured to receive IOS data and CT data as an input, the IOS data being obtained by performing scanning by an intra oral scanner and including coordinate data of a point group indicating a surface shape of a tooth row including an IOS crown and an IOS gingiva, the CT data being obtained by performing capturing by a CT imaging device and including volume data of a CT crown; and processing circuitry. The processing circuitry replaces, in the CT data, a crown part of a CT tooth included in the CT data with which a shape of the IOS crown matches, with the IOS crown included in the IOS data, and performs synthesis in such a way that the IOS gingiva is arranged near the IOS crown after replacement.

Abstract: A dental observation device by which, without displaying, in an overlapping manner, a visible light image of an image-capturing site in an oral cavity captured by a 3-D camera and 3-D image information on the image-capturing site in the oral cavity acquired in advance, an invisible portion in the visible light image is easily recognized.An observation system includes a visible light 3-D camera; a relative position calculator; a 3-D information storage storing 3-D image information acquired in advance; an image display displaying, side by side, a 2-D captured image captured by the visible light 3-D camera and 2-D converted image based on the 3-D image information corresponding to the surgical operation target site; and a display direction adjuster displaying, in the image display, the 2-D converted image in a predetermined direction on the basis of the image-capturing direction detected by the relative position calculator.
