Investigation of Bacterial Adhesion and Bactericide Effect ex Vivo on Different Implant Restoration Materials

Eight platelets with different material composition and surface properties are fastened in a holder (carrier rondell) with 15 mm diameter and inserted into the braces. Braces are to be worn for 28 hours in the oral cavity except for meals and oral hygiene procedures. Platelets then are removed and analyzed. After a first course the braces are to be cleaned in chlorhexidine solution in an ultrasonic bath; followed by a second identical course (Braces to be worn for 28 hours in the oral cavity except for meals and oral hygiene procedures).
