摘要：
A dental product is produced from material in powder form. In a first manufacturing stage, the product is given a shape which is larger than its final shape, and in further manufacturing stages the product is subjected to material shrinkage, sintering and working in order to obtain its final shape. Metal powder is applied to the mold tool, and the mold tool with the applied metal powder is placed in pressure-generating equipment where the powder applied to the mold tool is subjected to compaction pressure which compacts the powder so that at least 80% basic density is obtained in the material. The compacted material is then machined. After machining, the compacted material is removed from the mold tool. The sintering stage is then carried out so that the final shape is obtained.
