Dept. of Orthodontics. 1970.The present investigation was undertaken to determine an extra-skeletal reference plane and its reliability. The results of this study revealed that it seems possible for an orthodontist to establish an extra-skeletal reference plane, if a specially designed analyzer is used. It has been shown that by using this devise in his determination of a base landmark, an orthodontist can have a high degree of reliability within himself. It also appears likely that the reference plane obtained in this manner by one orthodontist is reproducible, to a high degree of reliability by other orthodontists. A remarkably high reproducibility, as obtained if a group determination of a reference base was done. To the orthodontist, it means that there may be a way of accurately producing a reliable reference plane for static cephalocentric analysis. This could be used to standardize communication among orthodontists.[TRUNCATED]en-USThis work is being made available in OpenBU by permission of its author, and is available for research purposes only.
