The facebow is a device used to mount the maxillary cast accurately on the articulator,
usually relying on arbitrary located anterior and posterior reference points. Mounting the cast
on the articulator in the appropriate position is an operator sensitive procedure, able to reduce
the chairside and laboratory time involved. There is little evidence available on the accuracy,
validity and reproducibility of articulator mounting of models (Tamaki et al, 1997; Celar et
al, 1999). The aim of our study was to assess the reproducibility of the face bow registrations
using two different arbitrary facebows.
