“…In numbers, the results were very similar, demonstrating again that the variation in crown material does not have a significant impact on the risk of fracture of the structure, since, as in the works of Gungor & Ylmaz (2016), Kaleli (2017) and Arinc (2018 ), the values found did not exceed the flow limits of the materials. This suggests a long clinical shelf life under the observed conditions (27,28,29).…”

“…There are four main factors that can affect the results in predicting the biomechanical behavior of stresses, such as the geometric detail of the object to be modeled, number of nodes and elements, types and properties of selected elements and boundary conditions. To carry out the analyzes in this work, as used by Gil (2017) and Arinc (2018), all materials used in the research were also considered homogeneous and isotropic, that is, all mechanical properties were considered the same, in all directions at the same point of the structural element (30,29).…”

The aim of this work was to evaluate the stress generated on the prosthetic intermediary in prosthetic crowns made with different materials using finite element analysis. Three-dimensional models of a portion of the maxilla with an implant and abutment screwed onto it were created. Three crowns for the first molar were constructed, and load simulations were carried out with axial (100 Newtons) and oblique (50 Newtons) forces, as follows: Model 1: prosthetic crown with a cobalt chromium infrastructure, 0.3 mm thick, and feldspathic porcelain roof; Model 2: prosthetic crown with a zirconia infrastructure on the abutment, 0.5 mm thick, and covering feldspathic porcelain; Model 3: zirconia prosthetic crown on the abutment, 1.5 mm thick. The results obtained in the external and inner portions of the intermediary were as follows: in the axial load, model M1 presented peaks in megapascals of 153.5, M2 of 153.6, and M3 of 156.1. In the oblique load, the peaks were in model M1 220.6, M2 220.7, and M3 220.5. In the inner portion of the intermediary, the peaks in megapascals in the axial load were 482.4 in the M1 model, 482.3 in the M2, and 482.3 in the M3. In the oblique load, they presented peaks of 672.8 in M1, 672.9 in M2, and 682.7 in M3. Quantitatively and qualitatively, there were no significant variations between the stress peaks in the outer and inner portions of the abutment, both in axial and oblique loads. Considering the models and methodology used, it is concluded that the mechanical performance of the different treatments analyzed is similar.

“…Although low‐elasticity modulus materials had a shock absorption effect, 22 the PEEK and CFR‐PEEK frameworks were not as effective as pure titanium and zirconia in improving the stress distribution, especially implant stress, in this study. Several previous studies reported that the shock absorption effect of polymeric materials was low 16,22 and accompanied by a low stress value in the framework and a high stress value in bone 22,43 . This finding indicates that polymeric materials pose a significant risk of bone resorption.…”

Purpose The objective of this finite element study was to investigate the effect of different framework designs, framework materials, and bone densities on the stress distribution of fixed implant‐supported prostheses for edentulous mandibles. Materials and methods Under the condition of 2‐mm cortical bone, 16 models were created in the edentulous mandible to simulate different framework designs (1‐piece or 3‐piece frameworks) with different framework material (pure titanium, zirconia, polyetheretherketone, or carbon fiber‐reinforced polyetheretherketone) in‐high or low‐density trabecular bone. Then, vertical loading and oblique loading at 75° were applied to the anterior and posterior regions. The stress distribution and stress concentration region of implant and peri‐implant bone with different combinations were compared by finite element analysis. Results The use of the 1‐piece zirconia framework in high‐density trabecular bone improved stress distribution on implants and peri‐implant bone. The region of stress concentration is located in the buccal cervix of the distal implants and the distobuccal portion of the cortical bone in all models. To improve the stress distribution on fixed implant‐supported dentures for edentulous mandibles, the 1‐piece framework and zirconia represent the better combination. Conclusion Under the condition of 2‐mm cortical bone thickness, the full‐arch zirconia framework had minimum von Mises stress on implants and peri‐implant bone in all models, and high trabecular bone density greatly decreased the stress on cortical bone.

“…The contact between the different structures was considered "bonded", meaning without sliding. All FPD infrastructures were metal-free with a zirconia infrastructure (modulus of elasticity 269,000 MPa and Poisson's ratio 0.25 -reference by Arinc [16] and Gungor & Yilmaz [17]), with feldspathic ceramic coating (modulus of elasticity 80,000 MPa and Poisson's ratio 0.30 -reference by Arinc [16] and Erkmen et al [18]), and closure of the screw holes with composite resin. The bones were type I, considered to be of good quality.…”

Objective: The present study analyzed the biomechanical behavior of the generated stress on the external surface of the rehabilitation elements (implants, components and infrastructures) according to different occlusion patterns on a fixed partial denture on osseointegrated implants. Method: The experimental groups varied according to the location of the occlusal load applied to the Fixed partial denture, with a total occlusal load of 750N in all groups, opting for greater loads on the occlusal table of the molar in relation to the premolar. This evaluation was performed by the finite element method with simulations by the AnsysWorkbench 16.0 Software program. Results: The results analyzed for implants and their components showed that the more posterior the occlusal loading, the greater the stress developed (group 4), always in the connection area between the prosthetic component and the implant, as this location can induce greater screw loosening. The results analyzed for the infrastructures showed that the most distributed occlusal loading possible (group 1) is the best situation for generating less stress. However, even in group 3 which obtained the highest stresses in the critical area of the prosthetic connection, the zirconia flexural strength values generated were not worrisome. Conclusion: It can be concluded that the occlusal adjustment of Fixed partial dentures are preponderant and decisive factors for correct biomechanics and preservation of the system in the long term in order to avoid possible damage and/or failures, and exert significant and notorious differences in the behavior of all structures studied herein.
