Does the prosthesis weight matter? 3D finite element analysis of a fixed implant-supported prosthesis at different weights and implant numbers

“…44 Moreover, there are studies which define that a zirconia infrastructure presents a similar biomechanical response to a titanium infrastructure, 34 while other reports define that more rigid materials are less damaging to the bone tissue. 45 These studies which compare implant infrastructures generally use the mechanical properties of the elastic modulus and the Poisson's coefficient of the simulated materials. 34,45 The elastic modulus and the Poisson's coefficient are properties related to the elasticity and plasticity of each material, allowing more or less displacement depending on the applied force.…”

Influence of novel implant selective laser melting framework design on mechanical durability of acrylic veneer

“…9 Likewise, the implant prosthesis metal framework is thought to play a significant role on the durability of the prosthesis and the veneering material. 13 Specifically, it is needed for acrylic reinforcement, reduce the bulk of framework and allow for cleansability of the prostheses. 3,4,13 This is more important in high stress regions such as cantilevers where the acrylic veneer will be subjected to heavy tensile stresses.…”

Carbon fibre versus metal framework in full‐arch immediate loading rehabilitations of the maxilla – a cohort clinical study

“…In implant prosthodontics, frameworks are used to improve the prosthesis rigidity and stiffness, reducing possible complications such as prosthesis fractures while rigidly splinting the implants together . Moreover, thanks to a rigid framework a more aesthetic prosthesis can be realised, especially when the prosthodontic space is limited.…”

“…Carbon fibre frameworks may be considered as a viable alternative to the metal ones and showed less marginal bone loss around implants and a greater implant survival rate during the observation period. KEYWORDS: dental implants, carbon fibre-reinforced composite, prosthodontics framework, immediate loading, dental prosthesis, cohort study Accepted for publication 9 February 2017 Background In implant prosthodontics, frameworks are used to improve the prosthesis rigidity and stiffness, reducing possible complications such as prosthesis fractures while rigidly splinting the implants together (1). Moreover, thanks to a rigid framework a more aesthetic prosthesis can be realised, especially when the prosthodontic space is limited.…”
