[Determination and position of the masticatory surface complex and clinically necessary corrections (with special...

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).
