Angela Codruta Podariu, Atena Galuscan, Daniela Jumanca Influence of Polyethylene Plate Thickness upon the Attrition of Dental Occlusal Appliances


Abstract:
This workpaper presents the assessment of the interaction between the dimension of glycol-modified polyethylene terephthalate (PETG) and the attrition of occlusal appliances by determining the degree and area of attrition of dental mouth guards made of PETG plates of different sizes: 0.8mm, 1mm, 1.2mm, 1.5mm, 2mm, 2.2 mm thick. The samples were made by thermoformed using the Erkoform device and inserted into the oral cavity subjects. The evaluation was made 2 weeks, 4 weeks and 6 weeks later. For evaluation it was used coloured occlusal spray. The best results were obtained with the 2 mm thick, but in our study the occlusal appliances with 1,2 mm had good results too. Keywords: occlusal appliances, glycol-modified polyethylene terephthalate (PETG), thermoformed
