Comparative Study on Biomechanical Behaviour of Non-Metallic Biomaterials used in Removable Protheses

The study aims to analyze the biomechanical behavior of flexible acrylates compared to conventional acrylates, acrylates reinforced with polyethylene fibers, polyamide structures, which are subject to tensile forces, respectively rupture, while the stresses induced in the structure of biomaterials. A number of 6 specimens were made, in the form of thin rectangular plates with a longitudinal dimension of 40 mm, the width of about 20 mm, having a thickness ranging from 1.8 to 2.5. From these traction specimens were made having the ends armed with aluminum plates glued with adhesive (cyanoacrylate). The tests were performed on a HEKERT 50 machine (on the 10 kN scale) and on a Textenser test machine (with a maximum force of 500 N) The specimen of the flexible acrylate has the highest resistance to force breaking. The specimens made of classical acrylate have fractured with the displacement of the fragments.
