[Testing the reliability of face bow registration]

The reliability of the Quick ear face-bow to transfer an arbitrary hinge axis to a Quick articulator was clinically compared with a Dentatus face-bow. 40 measurements were carried out on 8 patients with both instruments and were compared. The statistical analysis of the data indicated no difference between these facebow recordings. Furthermore both showed good reproducibility. This suggests that the same clinical results can be reached by these instruments.
