Oral appliance

摘要

An oral appliance particularly as a sports guard (1) for placing in a mouth of a user is disclosed. The guard (1) includes generally a base member (2) having a generally U-shaped form corresponding to the outline of a jaw of a user defining an upper channel (10) within which an upper row of teeth of a user can be received. The base member is made of polyethylene with less than 10 % by weight of a thermoplastics material having a greater flexibility than polyethylene and the base member is not user conformable or mouldable in boiling water. In addition, a teeth engaging element (3,4) is mounted over the base member (2) in each channel made of a thermoplastics material that is able to be user conformed or user moulded to suit the individual mouth of the user.
