[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 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...
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 کاملFarrington, T and Coward, T and Onambele-Pearson, G and Taylor, RL and Earl, P and Winwood, K (2015)The effect of model inclination during fabri- cation on mouthguard calliper-measured and CT scan-assessed thickness
Aim: Excessive material thinning has been observed in the production of custom-made mouthguards in a number of studies, due to production anomalies that may lead to such thinning. This study investigated the effect of thinning material patterns of custom made mouthguards when the anterior angulation of dental model was increased during the thermoforming process. Materials & Methods: A total of ...
متن کاملNumerical Simulation of Thermoforming
Numerical simulations of the large constrained deformation of polymeric structures frequently involves, at some stage, geometrical situations which are diicult to model. These are in addition to any diiculties encountered in the description and in the implementation of complicated con-stitutive relations. In the case of thermoforming the dii-cult geometrical situations occur as thin polymeric s...
