Strength Analysis of 6 Resorbable Implant Systems: Does Heating Affect the Stress-Strain Curve?

PurposeThe 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 MethodsRed 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.ResultsSeveral parameters were analyzed, and force versus displacement curves were plotted for each specimen.ConclusionsThere 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.
