Method for virtually modeling a dental arch

A method for virtually modeling a dental arch (10), wherein a plurality of overlapping images of the dental arch (10) and of a reference body (30) is captured from different angles of view and a virtual, three-dimensional dental arch model is computed from the captured images,

• wherein a partial impression (32) of the dental arch (10) on an impression plate (22) of known dimensions is used as the reference body (30), which impression plate (22) is provided with a pattern, and wherein the method further includes:
• computing a virtual, three-dimensional, preliminary dental arch model (100) from the images of the dental arch (10) captured intraorally,
• computing a virtual, three-dimensional reference model (300) from the images of the reference body (30) captured extraorally, and
• creating the dental arch model by correcting dimensions of the preliminary dental arch model (100) based on dimensions, realized in the reference model (300), of those structural features that are present both in the preliminary dental arch model (100) as well as in the reference model (300).
