Exclusion criteria

Exclusion criteria: The lower teeth are missing or the dental arch form is not suitable.

Design outcomes

Primary

MeasureTime frame
Investigations data are compared with a reference data set, which was previously generated by measurement of the transfer aid. The models of the subjects and the reference data are measured in the same way. The linear distances in between the centres of the spheres, the angles in between the normal vectors of two constructed planes and a superimposition with the reference spheres will be measured.

Secondary
