title: Stress Distribution Study Using the Finite Element Method in Three Different Implant-Supported Fixed Complete-Arch Mandibular Prostheses.
abstract: OBJECTIVE
  The objective of this study was to assess the stress distribution generated by a simulated loading (100 N) in the area of the cantilever in three different five-implant mandibular protocol prosthesis models.
  
  
  METHODS
  The finite element analysis was carried out in three-dimensional models simulating: (1) a temporary all acrylic resin mandibular protocol prosthesis; (2) a metal-acrylic mandibular protocol prosthesis; and (3) a metal-ceramic mandibular protocol prosthesis.
  
  
  RESULTS
  The all acrylic model promoted the highest stress values on the implant closest to the cantilever loading point.
  
  
  CONCLUSIONS
  This study supports the need for a metallic bar reinforcement in the denture base.
