Abstract: 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 from the anterior end. The sheets were placed in the forming machine with the sheet extrusion direction either vertica… Show more

“…The development of devices with various characteristics is progressing such as a semi‐automatic type and a device capable of indentations of the occlusal surface . Therefore, many researchers and clinicians use forming devices for mouthguard fabrication . However, thickness reduction of fabricated mouthguards can range from 35% to 60% .…”

“…Measurement points for the thickness of the incisal portion were defined at the left and right central incisor positions as follows: five equally spaced points from the proximal to the distal end of the incisal edge and 10 points on the labial surface (including five equally spaced points from the cervical to incisal edge along a line located one‐third of the distance from the proximal edge corresponding to the five points along a line located one‐third of the distance from the distal edge). Measurement points for the molar portion were defined at the left and right first molars as follows: There were 10 points on the buccal surface, including five equally spaced points from the cervical bulge to the tip of the cusp along a line located one‐third of the distance from the proximal end corresponding to the five points along a line located one‐third of the distance from the distal end (Figure ) . Measurements were performed once for each specimen.…”
