Abstract: The present invention relates to an orthodontic splint made of a crosslinked polymer, wherein the crosslinked polymer has a glass transition temperature Tg, determined by means of dynamic-mechanical analysis at a frequency of 1/s DMA as peak tan δ, of ≥25° C. and ≤60° C., a modulus of elasticity, determined by means of dynamic-mechanical analysis as the storage modulus E′ at a frequency of 1/s at 35° C., of ≥500 MPa and ≤4000 MPa, and a loss factor tan δ, determined by means of dynamic-mechanical analysis at a frequency of 1/s at 35° C., of ≥0.08. The invention further relates to a process for producing such splints.
