[Comparison of location between nasion and orbital points on soft tissue and on bony structures, in articulatory technique].

A skin projection of the orbitale as palpated through soft tissues was designated on the left cheek of 22 subjects. The nasion, orbitale and cephalostat nasion direction medium were plotted on transparent paper after teleroentgenography. Mutually parallel lines were drawn through the points, the line obtained on the construction of the nasion direction medium used as a basic one. Distances between the lines were measured and results statistically processed. Transfer of the model into the articulatory region by means of the orbitale and buccal arch nasion direction appeared not to orientate reliably the model according to reference planes of the head. Our results are consistent with literature data available.
