The invention discloses a dental prosthesis stent made of metal additives and a method for manufacturing the dental prosthesis stent made of the metal additives. The method includes: acquiring data of a three-dimensional maxillary model of a patient, selecting a maxillofacial surface of the dental prosthesis stent on the model, reconstructing the maxillofacial surface, stretching the maxillofacial surface until formation of an initial stent model, and repairing the initial stent model to meet design requirements for forming a stent CAD (computer aided design) model available for printing and manufacturing; adopting a selective laser melting 3D (three-dimensional) printer for printing and manufacturing to obtain a stent model, and subjecting the stent model to thermal treatment and surface treatment. The dental prosthesis stent comprises a body made of a metal material, and the body comprises a nesting portion and a supporting portion with a mesh structure. The dental prosthesis stent made of the metal additives and the method for manufacturing the dental prosthesis stent made of the metal additives have the advantages that the structure meeting clinical requirements is made by means of 3D printing technology, high precision, high surface quality and short manufacturing period are realized, and the clinical requirements are met better.
