Rapid Fabrication of Functional Mouthguard Using Rapid Tooling Approach
This paper presents the fabrication process of custom-made mouthguard with added features of air flow channel by using rapid tooling approach. Impression process was conducted in order to produce dental stone that will be used in thermoforming process to fabricate the custom-made mouthguard. Computer-aided design (CAD) were utilized to prepare the air flow channel’s design before attaching it a...
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 کاملEffect of ethylene vinyl acetate (EVA) closed cell foam on transmitted forces in mouthguard material.
OBJECTIVES To compare transmitted forces through ethylene vinyl acetate (EVA) mouthguard material and the same EVA material with gas inclusions in the form of a closed cell foam. METHOD EVA mouthguard materials with and without foam gas inclusions and 4 mm thick were impacted with a constant force from an impact pendulum. Various porosity levels in the foam materials were produced by 1%, 5%, ...
متن کاملBeneficial effects of air inclusions on the performance of ethylene vinyl acetate (EVA) mouthguard material.
OBJECTIVE To investigate the impact characteristics of an ethylene vinyl acetate (EVA) mouthguard material with regulated air inclusions, which included various air cell volumes and wall thickness between air cells. In particular, the aim was to identify the magnitude and direction of forces within the impacts. METHOD EVA mouthguard material, 4 mm thick and with and without air inclusions, wa...
متن کاملCombined analysis of shock absorption capability and force dispersion effect of mouthguard materials with different impact objects.
The aims of the present study were to investigate the shock absorption capability and force dispersion effect of mouthguard (MG) materials using load cell and film sensors. Two kinds of MG materials, ethylene vinyl acetate and polyolefin, were chosen for this study. When impact forces of approximately 5,000 N were applied on the MG materials using a round flat-nosed rod and a bluntly pointed ro...
