Abstract
Short‐term, experimental studies of partly laser‐modified implants with nano‐scale surface topographical features have recently shown a considerable increase in the biomechanical anchorage to bone. The aim of this study is to evaluate the biomechanical and bone‐bonding ability of partly laser‐modified implants compared with machined implants after a healing period of 6 months in a rabbit model. The results showed a 170% increase in removal torque. Histology and scanning electron microscopy demonstrated osseointegration for both implant types, but also revealed a different fracture pattern at the interface and in the bone. Transmission electron microscopy and chemical analysis showed coalescence between mineralized tissue and the nano‐structured surface of the laser modified implant. Taken together, the results indicate that nano‐structured surfaces promote in vivo long‐term bone bonding and interface strength. © 2011 Wiley Periodicals, Inc.
