Influence of Ceramic Materials on Biomechanical Behavior of Implant Supported Fixed Prosthesis with Hybrid Abutment

Purpose: This study evaluated the stress distribution in different cement-retained
implant-supported prostheses with a hybrid abutment. Materials and Methods: Two
factors were evaluated: restorative material for the crown and hybrid abutment - zirconia, lithium disilicate and hybrid ceramic, yielding 9 combinations. For finite element analysis, a monolithic crown cemented on a hybrid abutment was modeled and
cemented on a titanium base (Ti base). An oblique load (45°, 300 N) was applied to the
fossa bottom and system fixation occurred on the bone’s base. Results: Each structure was evaluated separately to find the possible weaknesses in geometry and failure criteria. In this context, results demonstrated a significant decrease of maximum
principal and von-Mises stresses concentration when crowns with high elastic modulus are cemented onto a hybrid abutment with lower elastic modulus. Conclusions:
Considering this theoretical study for a Morse taper implant, the association of a rigid
crown with a more resilient hybrid abutment reduces the tensile stress concentration
in the restoration cervical region.
