Abstract: A physical model of a set of teeth, wherein the physical model includes a gingival part in which a cavity comprising a cavity wall is formed; and a removable component having a part shaped as a tooth, where the removable component is configured for fitting into the cavity with a gap at an interface between the removable component and the cavity wall. The removable component or the cavity wall includes one or more supporting elements extending across the gap to establish contact between the removable component and the cavity wall to support and position the removable component in the cavity, and where contact between the removable component and the cavity wall at the interface only is provided by the supporting elements.

Abstract: A system for measuring a depth of a periodontal pocket defined by a gap between a tooth and gingiva includes a frame, one camera, and a processor. The frame is configured to be worn by a user. The camera is configured to capture at least one 2D image of an intraoral target area. The at least one 2D image includes a representation of at least a part of the tooth, a gingiva margin defined by a section of the gingiva adjacent to the at least a part of the tooth, and a probe tip when the probe tip is inserted into the periodontal pocket. The processor is configured to receive the captured at least one 2D image and to determine an insertion length of the probe tip in the periodontal pocket. The determined insertion length represents the depth of the periodontal pocket.
