The effect of masticatory forces within and outside the stable stress-bearing areas of the complete upper denture on the pressure gradient and the flow of saliva into the space under the prosthesis were demonstrated with standardized tests. It was shown that masticatory stress within the stable area led to a continual increase in pressure in the space under the prosthesis. Masticatory force outside the stable area led to a decrease in pressure and an equalization of pressure in this space as well as dislocation and tilting of the complete denture. Due to masticatory force outside the stable area, the shape of the ridge influences the stability of the complete denture.
通过标准化测试，证实了全口上颌义齿稳定承力区域内外的咀嚼力对压力梯度以及唾液流入义齿下方空间的流量的影响。结果表明，稳定区域内的咀嚼应力会导致义齿下方空间的压力持续增加。稳定区域外的咀嚼力会导致该空间压力降低和压力均衡，以及全口义齿的移位和倾斜。由于稳定区域外的咀嚼力，牙槽嵴的形状会影响全口义齿的稳定性。
