The influence of restorative material, bone height and implant system on the stress distribution of implant-supported posterior crowns
The evaluation of the biomechanical effect of different restorative material, bone height and prosthetic connection have not been evaluated yet in the implant-supported restoration. The finite elements analysis was applied for the numerical simulation of the generated stress and the microstrain in unitary implant-supported restoration. Two implant models (13 x 3.75 mm) containing external hexagon or Morse-taper connection were simulated. Both abutments received different screw-retained crowns (acrylic resin, cobalt-chrome, metal-ceramic or all-ceramic).
