The aim of this study is to investigate bacterial attachment and bactericidal effects of different materials used for the transmucosal part of implants. Using a brace, the intraoral biofilm formation in healthy subjects will be measured after 28 hours (24 hours intraorally, 4 hours rest). For this purpose 2 sterile platelets of each of the 8 differently processed materials (16 platelets in total) are inserted into the braces.~The main target parameter is the quantification of the biofilm by crystal violet staining. For this purpose the samples are analyzed by spectrophotometry at a wavelength of 595 nm (OD595).~As secondary target parameter possible bactericidal effects of the materials, which are analyzed by Colony forming units (CFU) determination, are used.
