Dental Splints and Sport Performance: A Review of the Current Literature

Abstract

Background/Objectives: Lately, there has been a greater focus on the function of the dento-mandibular apparatus, specifically on the location of the jaw and occlusion. Given the new potential insights, the current study aimed to comprehensively analyze the published literature on the use of occlusal splints and their effects on exercise performance. Methods: A search was conducted on PubMed, Scopus, and Web of Science for papers published between 2014 and 2024. Starting from the 128 identified records, 28 were finally included for review. Results: The extensive literature review revealed significant diversity in the experimental conditions, suggesting that the occlusal splints may enhance exercise performance and support dental health. Conclusions: The present study highlights the growing interest in occlusal splints research and its impact on sport and exercise science. Mouthguards or occlusal splints should continue to be worn in sports with a considerable risk of orofacial injury. Regardless of how they affect performance, mouthguards or occlusal splints are crucial for athletes in many sports to prevent oral and dental injuries.
