Article Synopsis
- The paper presents a methodology for studying the anisotropic elastic constants of phenylene polysulfide thermoplastic (PPS) printed via fused deposition modeling (FDM), to help designers achieve desired mechanical properties.
- While PPS has superior mechanical and thermal resistance compared to other plastics, conventional property data from manufactured samples do not accurately reflect the characteristics of 3D-printed parts, which show anisotropic behavior (different properties in different directions).
- The study involved printing haltera-type samples in various orientations, measuring their elastic properties, analyzing fracture behavior with SEM microscopy, and validating the findings through flexural testing and finite element simulations.
Purpose: Misfit in the conical implant-abutment interface plays an important role on the mechanical behavior of the implant when masticatory forces are applied. The origin of the misfit adopted in this work is a conical angle difference between implant and abutment, which can be due to a combination of design decisions and manufacturing tolerances. The goal of this work was to investigate the effects of the implant-abutment conical angle difference in the following mechanical features: interfacial microgap, preload loss on the bolt, stress level in the bone, and abutment removal force and/or torque.
