Abstract: The invention relates to a dental prosthesis part production method, wherein: a dental prosthesis part model is generated taking into account a dental model; a load analysis of the dental prosthesis part model is carried out; a first reinforcing structure model having a first shape and position is arranged inside the dental prosthesis part model and the dental prosthesis part model is reduced by a volume corresponding to the arranged first reinforcing structure model; the reduced dental prosthesis part model is divided into a lower partial volume and an upper partial volume; a lower part of the dental prosthesis part is produced from a first composite material according to the lower partial volume by means of the 3D printer; a first reinforcing structure corresponding to the first reinforcing structure model is arranged on the first part of the dental prosthesis part; and, by means of the 3D printer using the first composite material, an upper part of the dental prosthesis part according to the upper partial volume is placed onto the lower part of the dental prosthesis part comprising the arranged first reinforcing structure.
