METHOD AND DEVICE FOR THREE-DIMENSIONAL MEASUREMENT OF A DENTAL MODEL |
| 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 (10, 10') for generating two measurement areas of the dental model. Each split-beam measuring device comprises a first (20, 20') and a second (21, 21') camera system and a beam of light (30, 30'), wherein the optical axis (25) of the lens of the first camera system is inclined by a first triangulation angle (<xi) and the optical axis (26) 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 Ot1 is different from a2. Two dimensions of the three-dimensional model are recorded by means of a split beam, the third dimension being generated by a relative movement. The area and layer thickness of plaque substitute residues on the three-dimensional model are determined. |
