[The reproducibility of occlusal contacts in the Dentatus and Stuart articulators]

The reproducibility of occlusal contacts of 30 subjects was tested in the Dentatus and Stuart articulators. Primary contacts in the terminal hinge axis position were reliably reproducible in both articulators. Contacts in habitual intercuspidation were reproduced only approximately by both devices. Contacts in eccentric occlusion were satisfactorily reproduced in the Stuart articulator only. The findings show that doubts are indicated about the simulating capacity of semi-adjustable articulators which is frequently rated too high.
