Abstract:
A method for producing a dental product using titanium in powder form, where the product, in a first manufacturing stage, with the aid of a mould tool, is given a shape which is larger than a final shape of the product, and in further manufacturing stages is subjected to working and material shrinkage and sintering to obtain the final shape, comprising:applying titanium powder to the mould tool; placing the mould tool with the titanium powder in pressure-generating equipment; subjecting the titanium powder to compaction pressure and thereby compacting the titanium powder so that a compacted powder body having at least an 80 percent basic density is formed; machining the compacted powder body and subsequently removing the compacted powder body from the mould tool; and after removing the compacted powder body from the mould tool, shrinking and sintering the compacted powder body into the final shape to form the dental product, wherein material of the dental product has a porosity of at most about 6 percent by volume in said final shape.
