ABSTRACT
Objective:
To demonstrate a colorimetric photoelastic analysis of tension distribution around dental implants under axial loads. Material andmethods:
Eight different designs of implant from two manufacturers were connected to their abutments, placed into epoxy resin blocks and observed under a polariscope coupled to a universal testing machine while subjected to axial loads of 5 N. The obtained images were quantitatively analyzed by image analysis software.Results:
A strong correlation was found between the surface area and the implant fringe transition area (magenta color) of most samples (r = 0.908), and a moderate correlation was found between the fringe transition area and the mean thread height of the implants (r = 0.706, or r = 0.768 using a quadratic function).Conclusion:
By this biomechanical study, it was possible to demonstrate a correlation of some implant characteristics to the colored fringe areas of tension distribution, a colorimetric method that can be used in comparative studies of photoelastic analysis. Clinicalsignificance:
An accurate planning and knowledge of oral implant biomechanics is important so that a safe and long-lasting treatment can be achieved. This biomechanical study presented some correlations of the implant features and its photoelastic behavior, information that could be used by the practitioner while choosing the implant design for each clinical situation.
