Abstract :Abstract
For the therapy of parodontitis degradable poly(L-lactide) (PLLA) based threads are envisioned, which can be functionalized by relevant antibiotics. In this context first results on the release of tetracycline (TCL) out of PLLA specimens modified by casting and drying adhesive TCL loaded polyelectrolyte complex (PEC) particles are presented. A significant delay of the TCL release was found for the modification based on PEC/TCL in comparison to that based on pure TCL.
