This study highlights the importance of standardizing the thermoforming process, as this has a significant effect on the quality and material distribution of the resultant product. In particular, greater model inclination is advised as this optimizes the thickness of the anterior sulcus of the mouthguard which may be more prominently at risk from sport-related impact.
This study highlights variability in the finished thickness of the mouthguards especially in the anterior sulcus region measurement point, both within and between individuals. At the anterior region measurement point of the mouthguard, the mean thickness was 1.62 mm, equating to an overall material thinning of 59.5% when using a single 4-mm EVA blank. This degree of thinning is comparative to previous single operator research studies.
Despite bone healing and the management options of facial fractures being reported at length, there is a lack of evidence-based return-to-play criteria for sportspeople who have sustained these fractures. This shortage of evidence has resulted in a lack of consensus among health professionals. A prospective study of 20 cases of sportsmen who have returned to competitive play 3 weeks after injury or treatment for facial fractures is reported. The risks and benefits of early return-to-play are discussed and return-to-play guidelines for these patients are proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
