This study is aimed at the improvement of the biomaterials used in the field of entirely removable prosthesis quality. One important aspect taken into consideration is the adhering of the Candida albicans fibres, a bacterium frequently met at the oral cavity level of old patients, to different variations of acrylate, in search of ways of counter-attacking this tendency of a very resistant microbian structure.A number of 19 test-tubes were made under the shape of thin, rectangular plates, 40 mm long and 20 mm wide and a depth varying from 1.8 to 2.5.After analysing the test-tubes for traction forces, was observed: The beraking of the base material was followed by the taking over of the force by the metallic net: the small (elastic) distortions of the acrylate were not simultaneous with the distortions of the reinforcement materials. Polyethylene fibres are made by twisted threads and it presents a lower elasticity module compared tot hat of the acrylic resin, especially duet o the ondulation of the fibres.Among the advantages of the use acrylic bases renforcement with polyetilene fibres we notice its lower interface effect in comparison with the net acrylical reinforcement. |
