Abstract: Provided are an intraoral image processing method and an intraoral image processing apparatus. The intraoral image processing method includes obtaining an intraoral image generated by scanning teeth, segmenting teeth of the intraoral image, generating a customized curve based on one or more teeth included in the intraoral image, and obtaining a final position of teeth by arranging teeth segmented from the intraoral image to be aligned with the customized curve.

Abstract: According to embodiments, a method and apparatus for processing a three-dimensional (3D) intraoral model are provided. The method of processing a 3D intraoral model may include obtaining a tooth model and a gingival model from the 3D intraoral model, deforming the gingival model by reflecting an amount of movement of gingiva according to a displacement indicating movement of one or more teeth included in the tooth model, obtaining a final gingival model by suppressing, using one or more control factors, at least a part of the displacement indicating movement of the teeth from being reflected in the amount of movement of the gingiva, and displaying, on a display, the obtained final gingival model and a final tooth model representing movement of the one or more teeth included in the tooth model.

Abstract: An intraoral image processing device and an intraoral image processing method are provided. The intraoral image processing method includes obtaining an intraoral image generated by scanning teeth, aligning a teeth model template including a plurality of template teeth to teeth in the intraoral image, obtaining a plurality of tooth pieces by separating the teeth of the intraoral image, and individualizing the teeth of the intraoral image by collecting one or more tooth pieces corresponding to each of the aligned template teeth.

Abstract: Provided is an area determination method for determining an area corresponding to an object from a three-dimensional model of an oral cavity. The area determination method includes: obtaining the three-dimensional model; determining a seed point on the three-dimensional model; based on the seed point, determining a reference point on the three-dimensional model; determining an area corresponding to an object, by gradually expanding a selection area based on the reference point; and displaying the determined area on the three-dimensional model.
