MMA-free plastic for the fabrication of functional occlusal splints with thermoplastic memory effect. The material is flexible at body temperature, thus leading to increased wearing comfort. At the same time, the material features a high restoring torque at room temperature, high tensile strength, durability and permanent transparency. The unique manufacturing process ensures that the finished splints remain flavourless over time. Available as a milling blank in thicknesses of 16 and 20 mm and as self-curing resin for use in the casting and moulding techniques.
