摘要： The invention relates to a method for determining the cleaning performance of dental cleaning products. To do so a device for three-dimensional measurement of a dental model is provided. The device has two split-beam measuring devices for generating two measurement areas of the dental model, wherein the measuring areas are different from one another. Each split-beam measuring device comprises a first and a second camera system and a beam of light, wherein the optical axis of the lens of the first camera system is inclined by a first triangulation angle (O1) and the optical axis of the lens of the second camera system is inclined by a second triangulation angle (a2) with respect to the plane of the beam of light, where Ci1 is different from a2. The dental model and the split-beam measuring devices are arranged so they can be moved in relation to one another. Two dimensions of the three-dimensional model are recorded by means of a split beam, the third dimension being generated by the relative movement. The area and layer thickness of plaque substitute residues on the three-dimensional model are determined. The cleaning performance of different dental cleaning products can thus be effectively compared.
