Mechanical Stress Analysis of Different Configurations of the All-on-4 Concept in Atrophic Mandible: A 3D Finite Element Study.

CONCLUSION: The higher odds of technical failures (screw fracture/loosening) may be expected when the All-on-4 configuration is performed with tilted standard posterior implants. Also, peri-implant bone overload may occur when the All-on-4 design is performed with straight short or straight standard posterior implants in atrophic mandibles.
