Abstract

Micromovement is a key factor to the success of osseointegration of dental implants. It has been suggested that micromovements of 150 micron can be supported by peri-implant bone tissue without the formation of fibrous tissue at the bone/implant interface. This study aims to evaluate the stress and strains on the peri-implant bone tissue when micromovements occurs in conical and cylindrical implants through finite element analysis. Geometric models will be made using a 3-D modeling software (SolidWorks 2010, USA) which will be exported to an specific software for the finite element analysis (ANSYS Workbench 12, USA). Micromovements (50, 150, e 250 ¼m) will be simulated in clockwise and counterclockwise directions. All the analyses will evaluate the von Mises, Maximum Principal Stress and microstrain on the peri-implant bone tissue. Results will be presented in a qualitative way through figures with the stress distribution in different color gradients, and quantitatively by reading the stress in certain regions of the models.
