Background/Aim Polyolefin sheets are fabricated in the same manner as ethylene vinyl acetate sheets. The aim of this study was to examine the difference of vacuum‐formed mouthguard thickness according to each heating condition using ethylene vinyl acetate and polyolefin sheets. Materials and Methods Mouthguard sheets of 3.0 mm ethylene vinyl acetate and polyolefin were vacuum‐formed on working models at three heating temperatures: 85, 95, and 105°C. The thickness of the mouthguard was measured at the labial surface of the central incisor, the buccal surface of the first molar, and occlusal surface of the first molar. Differences in the thickness of the mouthguards according to the sheet materials and the heating conditions were analyzed by two‐way analysis of variance. Results Mouthguard thickness varied between the ethylene vinyl acetate and the polyolefin sheets (p < .01), and the thickness of the ethylene vinyl acetate sheet was greater than that of the polyolefin sheet at all heating conditions. The thicknesses of mouthguards fabricated using the ethylene vinyl acetate and the polyolefin sheets were not different for the three heating conditions in this study. Conclusions The thickness was greater for mouthguards fabricated using ethylene vinyl acetate sheet than when polyolefin sheet was used. The thickness of the mouthguards was not different for the three heating temperatures for both the ethylene vinyl acetate and the polyolefin sheets.

Mouthguards have been used for the protection of the mouth from trauma during sports. [1][2][3] Mouthguard thickness influences its shock absorption ability and its protection ability. [4][5][6] Therefore, it is important to maintain a uniform mouthguard thickness.

A bstract Aim To evaluate the stress distribution of calculated standardized force on maxillary and mandibular jaw bones with proclined maxillary anterior teeth with and without the use of a mouthguard. Materials and methods It's a finite element analysis (FEA) study. Maxillary and mandibular jaw models with and without mouthguard (4 mm) were created using a cone-beam computed tomography (CBCT) scan of a 13-year-old male patient with proclined maxillary anterior teeth. Calculated standardized forces were applied on the maxillary central incisors in the horizontal direction of the created model. The von Mises stresses (MPa) were analyzed on the maxillary and mandibular jaw. Results Higher von Mises stresses were analyzed in the maxillary and mandibular jaw model without a mouthguard compared to the model with a mouthguard. Forces were more evenly distributed in the maxillary and mandibular jaw models with a mouthguard. Conclusion A mouthguard can be used to reduce and evenly distribute the stress on the maxillary and mandibular jaw with proclined maxillary anterior teeth when exposed to real-life situation forces. Clinical significance The force of injury is influenced by the size of the object or the velocity at which the athlete hits the object/individual. There is a need to evaluate the force at which the individual athlete hits the object/surface based on average height, weight, and velocity/performance at that particular age. As the age of the athlete's advances, there is a change in the height, weight as well as performance. This factor will influence the impact and severity of the trauma caused during sports activities. So, these parameters should be considered while designing the mouthguard for its better effectiveness. How to cite this article Doiphode AR, Kalaskar R.
