title: [Modelization of bone graft reconstruction for posterior mandibular segment using the Simplant® software].
abstract: BACKGROUND
  Pre-implant reconstruction techniques of edentulous molar mandibular ridges take into account the height and the width of the initial ridge, but not the initial geometry. The Simplant(®) software allows modeling these techniques by taking into account this geometry.
  
  
  METHODS
  Four surgical techniques for crestal volume reconstruction (apposition, interposition, distraction, formwork) were used on seven hemi-mandibles and modeled with the Simplant(®) software. This reconstructed volume was visualized according to the initial crestal geometry. The average gain in height was 4.1mm for the onlay graft, 2.3mm for the interposition graft, 4mm for distraction, 5.1mm for the boxing. The average gain of crestal width was -0.3mm for the onlay graft, 1mm for the interposition, -0.5mm for the distraction, and 1.3mm for the boxing.
  
  
  CONCLUSIONS
  Modeling with the Simplant(®) software shows that boxing technique gives the closest bone reconstruction to the ideal crestal geometry, whatever the initial crestal geometry.
