[An abnormal course of the Th1-root of the brachial plexus in connection with a variety of the anterior scalenus muscle].

A scalenus anterior muscle with 2 insertions was found - one insertion at the Tuberculum m. scaleni anterioris, the other at the osteo-cartilaginous border of the 1st rib. In the thus formed opening, limited by the 2 insertions and the 1st rib, the Th1-root of the brachial plexus emerged. Its other roots passed between the scalenus anterior and medius muscles as usual. An aponeurotic membrane, attached to the inner margin of the 1st rib and narrowing the upper thoracic aperture prevented the Th1-root from crossing over the 1st rib behind the Tuberculum m. scaleni anterioris as it normally does.

[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.

[Function-analysical studies of class II abnormalities. A contribution to the study of the articular reaction in activator treatments].

In patients treated with an activator the individual axial hinge points lie on the average 4.5 mm more ventral than in untreated patients. In those treated, the analytically calculated gliding movement of the condyles from the posterior position of contact to habitual intercuspidation on the average was 0.88 mm compared to 0.36 mm in the untreated. Movement of the teeth amounted to 1.18 mm in group 1, and 0.46 in group 11.
