ABSTRACT: Purpose: The aim of this study was to clarify the effect of occlusal correction using an intraoral appliance on flight time during barani jumps in trampoline competitions. Method: Thirteen male trampoline gymnasts (17.5 ± 2.4 years) were selected as participants. Custom mouthguards were fabricated for each gymnast and were adjusted so that all teeth were in even contact with light clenching. The trial consisted of 10 consecutive barani jumps. Flight time was measured using an HDTS all-in-one measurement system. Measurements were performed at three time points: before the participant wore the mouthguard, immediately after wearing, and 2 months after wearing. Differences among measurement time points in the maximum flight time for one jump and the total flight time for 10 consecutive jumps were compared using one-way analysis of variance using repeated measurements. Results: Two months after participants started wearing the mouthguard, the maximum flight time for one jump was significantly longer than the before time point (P P P
