[Quantitative studies on the retention mechanism of complete dentures. I. Studies on a phantom model]

In four full maxillary dentures, the physical mechanisms of retention were examined and quantitatively determined by inductive pressure and motion recorders, in tests performed on a model and on the patients. In addition to capillary or viscous forces, the pressure difference existing in the space between denture and palate on the one hand and the oral environment on the other and resulting during pull-off, provides the greatest retaining effect.
