  2. Gap • Surface roughness of implanted materials affect adhesion quality • Macro scale testing borrowed from other industries http://www.instron.us

  3. Objective • Design an apparatus to investigate the effects of various surface topographies on the adhesion of implants to bio-materials. • Simulate mode 1 fracture • Apply, measure and correlate force and displacement data • Scaleable IMMEDIATE OCCLUSAL LOADING™ (IOL™) OF DENTAL IMPLANTS: Predictable Results Through DIEM™ GuidelinesRichard J. Lazzara, DMD, MScD

  4. Objective • Force vs Roughness crack length • Force vs Linear crack length Images courtesy of Dr. Kohles
