Conditions
Summary
Type III (custom-made) intra-oral protection (IOP) models represent 13% of IOP worn by amateur rugby club players in France. However, this model is recognized as the most effective when made in accordance with essential health and safety requirements. This observation is at the origin of a new approach that the investigators are proposing with the objective of removing the barriers to access to custom-made IOP. This research is based on the combination of new digital technologies, scanning and 3D printing, to develop a new generation of IOP. This project aims to show the interest of this new generation of "modified unimaxillary" IOP on the ventilation of the athletes and his/her comfort when he/she evolves with his IOP in place

Interventions
Manufacture of custom-made "unimaxillary" and "modified unimaxillary" intra-oral protection (IOP) with vertical dimensions of 4 mm and 6 mm. 3D modeling of a IOP based on: * digital recording of the maxillary and mandibular dental arches * mandibular wedging performed with an inter-arch piece * digital recording of the inter-arch position
Realization of a ventilation test (VO2max) to determine the Maximum Aerobic Speed (MAS). Measurement of ventilatory parameters without IOP and with each IOP : * At rest, standing still. * During a 4 minute run on a treadmill at 50% of MAS. * During a 4-minute run on a treadmill, at a speed corresponding to 70% of MAS
