Abstract

Tactile and pain sensitivity of the oral mucosa has been the subject of study of a number of researchers. However, the numerical values of the thresholds of the excitation of the baro - and mechanoreceptors of the mucosa of the oral cavity not sufficiently detailed in the literature, experimental data is highly scattered, often presented without specifying the method of measurement or sections of the jaws, which were received. However, the authors note the unequal sensitivity of the mucous membrane in its different areas and its dependence on the presence or absence of a number of chronic diseases. Systematic study on the diagnosis of sensitivity associated with dental prostheses of the prosthetic bed tissues to pressure, virtually no. In this report the authors made some attempt to rectify this gap. It shows the numerical values of thresholds of pain sensitivity of the mucous membrane of the oral cavity of humans and animals by mechanical action on the basis of literary data and results of numerical analysis of the mathematical model “obturator maxillary prosthesis - mucosa the edges of the defect of the upper jaw”. The average value of the lower threshold of pain sensitivity was 20,72 g/m2 according to the data of different authors, and the upper limit was 63,82 g/m2.
