Summary

The aim of this work is to determine the susceptibility of a polymer prosthetic material containing poly(methyl methacrylate), to solutions degrading. A measurable aim of this paper is to prove how important it is to exchange total restorations in the prosthetic treatment, due to the degradation of the material from which they are made. The scope of work includes examining the susceptibility of prosthetic material to liquid simulating the environment conditions in the human oral cavity. The hydrolysis, oxidation, artificial saliva and amylase solutions were used during the test. Susceptibility of the test material was checked by changing the weight and surface morphology of samples and changing their thermal properties.The results concluded that poly(methyl methacrylate) is susceptible to degradation in model body fluids.
