Strength analysis of 6 resorbable implant systems: does heating affect the stress-strain curve?

Purpose: The objective was to directly compare the strength of 6 different resorbable implant plating systems using an in vitro model before and after heating.

Materials And Methods: Red oak wood was cut and fixated using various resorbable plates and screws. Vertical load was applied and the specimens fractured, while a test machine gathered data. This was repeated after heating of the specimens.

Results: Several parameters were analyzed, and force versus displacement curves were plotted for each specimen.

Conclusions: There were no statistically significant differences for total maximum loads between heat-treated and non heat-treated specimens. There were differences in strengths amongst the various systems.
