Zusammenfassung:Provided are an oral scanning image processing method and apparatus. The method comprises: determining an alveolar process associated area on the basis of a sagittal projection image corresponding to an oral scanning image, wherein the alveolar process associated area comprises a mandibular alveolar process area and at least part of a mandibular ramus area; obtaining an axial projection image corresponding to the alveolar process associated area, which is in the oral scanning image; performing image segmentation on the axial projection image, so as to obtain a dental arch mask image; and obtaining a dental arch curve on the basis of the dental arch mask image. The alveolar process associated area is not affected by the state of a field of view and the condition of teeth in an oral cavity, such that the process of obtaining the dental arch curve is not constrained by the state of the field of view and the condition of the teeth in the oral cavity. In this way, a stable and accurate dental arch mask image can b
