Artificial Teeth and Its Resistance to Wear : Resistance of acrylic teeth

Denture teeth are made of either Acrylic Resin or porcelain. It has been observed that, in the oral cavity posterior denture teeth wear faster than the anterior teeth, causing occlusal prematurities and loss of vertical dimension of occlusion. The loss of vertical dimension of occlusion lays more stress on the anterior alveolar ridge, which in turn increases the rate of residual ridge resorption and causes loss of alveolar ridge height in the anterior segment and compromises esthetics. Hence it is important for the clinician to choose acrylic resin teeth which demonstrate optimum physical and mechanical properties to withstand rigorous demands of masticatory functions.
