[The intraoral bacterial colonization of temporary denture plastics]

Plastic materials used for temporary crowns and bridges in prosthetic dentistry are investigated with regard to the possibility of their microbial colonization. For this purpose four different kinds of materials, i.e. Resincap, Trim, Snap (Polyalcylmethacrylate) and Protemp (Bisphenol-A-Glycidyl-Methacrylate) were chose. With the help of 10 test persons in vivo experiments were carried out. After a period of two weeks it could be verified, that the bacteria have a stronger affinity to Protemp than to Polyalcylmethacrylate. The hypothesis, that the different intensity of colonization is due to the roughness of certain surfaces could be confirmed by additional experiments.
