[Thickness of mouthguard sheet material after vacuum forming process depending on the thickness of mouthguard sheet].
PURPOSE Mouthguards are available to provide protection from stomatognathic injury during sports. The aim of this study was to examine the thickness of each part of mouthguard sheet depending on the thickness of mouthguard sheet material. METHODS Cross stripes (10 x 10 mm) were printed in mouthguard sheets. We measured the thickness of each cross stripe area using a measuring-device (R). Two ...
متن کاملThickness of mouthguard sheets after vacuum-pressure formation: influence of mouthguard sheet material.
The aim of this study was to investigate the thickness of mouthguard sheet after vacuum-pressure formation based on the mouthguard sheet material. Three mouthguard sheet materials (4.0 mm thick) were compared: ethylene-vinyl acetate co-polymer (EVA), olefin co-polymer (OL), and polyolefin-polystyrene co-polymer (OS). The working model was made by hard gypsum that was trimmed to the height of 20...
متن کاملInvestigation of vacuum forming techniques for reduction of loss in mouthguard thickness: part 2—effects of sheet grooving and thermal shrinkage.
The aim of this study was to investigate vacuum forming techniques for reduction of loss in mouthguard thickness effects of sheet grooving and thermal shrinkage of extruded sheets on molded mouthguard thickness. Mouthguards were fabricated with ethylene vinyl acetate (EVA) sheets (4.0 mm thick) using a vacuum forming machine. Sheet form was a convexing v-shaped groove toward the back, 10-40 mm ...
متن کاملCharacterization of Microstructure and Bending Response of Sheet Material: Influence of Thickness
Bending process is one of the most significant fields of application of sheet metal die. In bending process, it is quite vital that the product should have the desired angle. Furthermore, in order to obtain the desired angle in the bent parts, spring-go and spring-back amounts must be known. In this study, 30o, 60o and 90o bending processes were applied to S235JR (1.0038) sheet metal having 3, ...
متن کاملDifference in pressure-formed mouthguard thickness according to heating condition.
PURPOSE The purpose of this study was to investigate the differences of pressure-formed mouthguard thickness by varying the heating conditions within the proper heating temperature. MATERIALS AND METHODS The material used in this study was a mouthguard sheet of 3.8-mm ethylene vinyl acetate. The sheets were formed by pressure forming using a vacuum-pressure former. Three heating conditions we...
