Abstract

Mechanical interlocking concept is a crucial criteria for osseointegration which is based on micro-porous surface structures. Several surface treatment methods have been used to modify the surface morphology of titanium implants in order to increase the effective interfacial area. The aim of the present preliminary study is two folds: to develop 3D finite element models for micro-pits on implant surfaces as bone stabilizers in order to evaluate the mechanical response of interfacial area and compare the estimated interfacial shear strength and the maximum effective shear strain with other biomechanical theories. Second is to produce novel regular micro-pit patterns using a 20 Watt ytterbium fiber laser and characterize these novel micro-stabilizers.
