RESUMO
A phonetic and relaxation method combined with teleoradiography was used to measure the interocclusal interval in five subjects. The action potential of the left and right masseter muscles were derived while the subject was drinking liquid. After fitting each subject with a Shore bite path plate which reduced the interocclusal interval to 0 mm, the same experimental procedure was carried out. No significant differenced could be established using a unidirectional lead with pseudointegration. In spite of the extremely small sample, the results tend to indicate that resting suspension changes corresponding to the vertical dimension.

The individual calotte articulation recommended by C. U. Fehr in 1947 has been used at the Free University of W. Berlin for clinical teaching since this time. The following studies were described and/or recalled and contrasted with other methods for determining position: 1. Studies of Grabert mandibular posture compared with the Ivo-Tray model. 2. Stoebe's studies of calottes with various radii, 3. Eichner's and Schmitthelm's roentgencinematographic studies, 4. Reese's study of biting force, 5. Husemann's comparison of different relational determinations, 6. Sauer's study of the success of reocclusion. Based on the clinical results and also the results of difficult comparative studies. we see no reason to depart from functional determination of relation using calotte-shaped, curved wax walls. Clinical example of the grinding surface complex, which is part of the method, guarantees construction of the complete denture within the range of tissue adaptation. No elaborate apparatuses are required. Even complicated tracing methods do not eliminate the possibility of additional work (e.g., removal of pressure areas, reocclusion).
