Provided is a method of setting a scan region, the method including: placing a target object on an upper surface of a jig of a three-dimensional scanner in such a manner that at least one portion of a target object image representing a shape of the target object is plotted on an input region; determining, by a control unit, a predetermined upper portion of the input region, as a scan region, from a jig image representing the shape of the jig; and generating, by the control unit, a three-dimensional model of the target object on the basis of the target object image resulting from scanning the scan region.

The present disclosure relates to a method for self-investigating an optical element embedded in an intraoral scanner, and a system using the same. The reliability of an intraoral scanner may decrease due to foreign matter attached to an optical element. Accordingly, the present disclosure provides a prescribed method for investigating foreign matter attached to an optical element, and a system using the same, wherein an alarm providing notification of the need to inspect the optical element is generated when it is determined that foreign matter has stained the optical element. According to said investigation method and system, a user of an intraoral scanner can automatically determine the presence or absence of foreign matter when scanning an object (patient's affected area), and thus can service the optical element or replace a part in which the corresponding component is formed. Therefore, there is an advantage of improving the scanning efficiency and data reliability of the intraoral scanner.

The present disclosure relates to a method for processing scanned images from an intraoral scanner, an apparatus for performing the method, and a recording medium for recording instructions for performing the method. An image processing method according to some embodiments of the present disclosure, which is implemented by an electronic apparatus, may include: identifying a tooth region in a two-dimensional image of a target oral cavity; identifying, in the two-dimensional image, a first neighboring region located within a predetermined distance from a boundary of the tooth region; determining, based on a difference in depth between the tooth region and the first neighboring region, whether to include the first neighboring region in a region of interest; and generating a three-dimensional image of the target oral cavity from the two-dimensional image which includes the region of interest.

Provided are an intraoral image processing method and an intraoral image processing apparatus. The intraoral image processing method includes obtaining three-dimensional (3D) intraoral data of a scanned object; creating a 3D intraoral image including a scanned surface area and a rear surface area of the scanned surface area, based on the 3D intraoral data; and deleting at least a portion of the rear surface area.

An occlusion alignment method according to the present disclosure includes: extracting at least one tooth area data from upper jaw scan data and lower jaw scan data; and adjusting an occlusion position of the upper jaw scan data and the lower jaw scan data using the at least one tooth area data.

A three-dimensional modeling method according to the present invention includes: a scan step of scanning a subject to be filtered so as to obtain at least one set of image data; a step of determining a reference color or a reference color range from a color included in the image data obtained in the scan step and filtering the reference color or the reference color range; and a step of generating a three-dimensional surface model of a subject to be modeled by scanning the subject to be modeled, wherein the step of generating the three-dimensional surface model includes excluding the reference color or the reference color range to generate the three-dimensional surface model.

The present disclosure relates to a data processing method and a data processing device. The data processing method, according to the present disclosure, comprises: generating, based on tooth data, a first arch line which is a spline curve in contact with contours of a plurality of teeth constituting the tooth data; generating, from the first arch line, a second arch line that is different from the first arch line; and moving a target tooth, which is to be moved, among the tooth data toward the second arch line according to an input signal of a user.

An archline optimization method according to the present disclosure includes generating a Spee curve based on an arc of a circle having a predetermined radius of curvature, and changing a three-dimensional archline based on the Spee curve.

The present invention relates to a system for displaying orthodontic information of an oral cavity and, more specifically, to a system for displaying orthodontic information of an oral cavity, the system being capable of displaying changes in the positions of teeth to be corrected and also displaying a tooth extraction state, by using oral cavity scan data obtained by scanning the shape of a patient's oral cavity for orthodontic treatment. The system for displaying orthodontic information of an oral shape, according to the present invention, enables movements of teeth for the patient's orthodontic treatment to be easily displayed or enables teeth to be extracted to be easily displayed, and enables the shape of the oral cavity after orthodontic treatment and tooth extraction are finished, to be visually displayed in an easy and quick manner, thereby facilitating the establishment of a plan for orthodontic treatment.

The present disclosure relates to an apparatus, a method, and non-transitory computer-readable recording medium storing program for generating and aligning a three-dimensional image model of a three-dimensional scanner. The apparatus according to one embodiment of the present disclosure may: obtain first scan data values for a surface of an object by first scanning by the three-dimensional scanner, the first scan data values including three-dimensional coordinate values, generate a first three-dimensional image model based on the first scan data values, obtain second scan data values for the surface of the object by second scanning by the three-dimensional scanner performed after generation of the first three-dimensional image model, the second scan data values including three-dimensional coordinate values, and generate a second three-dimensional image model by automatically replacing at least a part of the first scan data values with the second scan data values or based on the second scan data values independently of the first three-dimensional image model.
