Abstract

According to the World Health Organization, the oro-dental health is an important pylon of the quality of life. In this context, the edentation (loss of tooth) represents the pathological state peak of the oral cavity with a negative impact on the physiology of the human body. This study proposes a comparative evaluation on the resistance to tension of two highly used dental materials used in dental prosthetics such as poly (methyl methacrylate) and composite resin. The obtained result highlights a greater resistance of poly (methyl methacrylate) than composite resins, also put forward that a high temperature realizes a complete polymerization of poly (methyl methacrylate), and consequently presents higher resistance. To characterize sample TEM (Transmission Electron Microscopy) techniques was used, included conventional images, selected area electron diffraction, and high-resolution images..
