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 delta, of >= 25 DEG C and <= 60 DEGC, a modulus of elasticity, determined by means of dynamic-mechanical analysis as the storage modulus E' at a frequency of 1/s at 35 DEG C, of >= 500 MPa and <= 4000 MPa, and a loss factor tan delta, determined by means of dynamic-mechanical analysis at a frequency of 1/s at 35 DEG C, of >= 0.08. The invention further relates to a process for producing such splints. 本发明涉及一种由交联聚合物制成的颌正畸牙齿夹板，其中所述交联聚合物的玻璃化转变温度Tg≥25℃且≤60℃，借助于动态力学分析在1/s DMA的频率下作为峰tanδ测定，弹性模量≥500 Mpa且≤4000 MPa，借助于动态力学分析作为储能模量E'在1/s的频率下在35℃下测定，和损耗因子tanδ≥0.08，借助于动态力学分析在1/s的频率下在35℃下测定。此外，本发明涉及用于制造这种夹板的方法。
