title: Strength analysis of 6 resorbable implant systems: does heating affect the stress-strain curve?
abstract: OBJECTIVE
  The objective was to directly compare the strength of 6 different resorbable implant plating systems using an in vitro model before and after heating.
  
  
  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.
