The invention relates to a three-dimensional orthodontic retainer (2) and to a method for producing such a retainer (2) in which the three-dimensional orthodontic retainer (2) is matched to the exact shape of the adjacent teeth (3) and is produced from a blank (1) in such a manner that the physical properties of the material of the remaining part of the blank (1) are unchanged in the retainer (2). The method for producing the three-dimensional orthodontic retainer (2) comprises the following method steps: creating a three-dimensional model of the structure of the patient's teeth (3)； designing a customised, precisely fitting model of the retainer (2)； producing the retainer (2) on the basis of the designed 3D model by computer-controlled deposition or application of material.
