Oral Session: Scientific Groups - 75. Implantology II: no. 559OBJECTIVES: To study the contact electrification phenomena between grits and CP2 Ti during sandblasting which is a novel finding in surface modification of Ti dental implant. METHODS: Our experiment investigates the possibility of applying contact electrification in modifying the surface charge of titanium dental implants. through sandblasting, which involves contacts and charge exchanges between the grits, the implant and air. Although sandblasting is commonly used for roughening the titanium surface, previous research has totally neglected its electrical effects. Al2O3 grits with average ...postprin
