Gap • Surface roughness of implanted materials affect adhesion quality • Macro scale testing borrowed from other industries http://www.instron.us
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
Objective • Force vs Roughness crack length • Force vs Linear crack length Images courtesy of Dr. Kohles
Frame 6061 Al Pyramid design - strength, visual access Secure specimen jig Houses motor and laser Electric Motor 3V 1300 to 1 Gear reduction Design Components
Design Components • Specimen Jig • 6061 Al • Simulate mode 1 fracture • House test specimens • Houses other components • Sensor Array • Input light and voltage, output resistance • Scaleable
Design Components • Laser • Powerful and concentrated light • Fanned horizontally • Drastic contrast to ambient light • Force Sensor • Compression sensor adapted • Input voltage and force, output resistance
Design Components • Test Specimens • Machined plastic bars • Simulated bio materials • Varying mechanical properties
Conclusion • All design components are scaleable • Proof of concept achieved
