All-On-4: Effect of Tilting Angles

How do different tilting angulations of implants effect stress values? A recent study 1, evaluated the effect of implant inclination and cantilever length on the stress distribution in mandibular cortical bone, implant, abutment, prosthetic framework, and prosthetic screw via three-dimensional (3D) finite element analysis (FEA). Four different finite element models were designed according to the tilting angle of the posterior implant and angle of multiunit abutments.
The conclusion:

Biomechanical comparison via 3D FEA revealed that decreasing the cantilever length by tilting the posterior implants resulted in a reduction in stress values in the peri-implant bone, abutment, prosthetic screw, and metal framework. The groups with 30- and 45-degree tilted posterior implants and shorter cantilever lengths showed better stress distributions in comparison to the straight and 17-degree tilted groups.1 Read More
