Application filed September a, 1920. serial-no. mates.
Essen, Germany, has invented certain new 5 and useful Improvements in Material for Artificial Internal Memb'ers'of the Human Body, of Whichthe following is a specification.
The invention refers to artificial members organisms, in particular to supports for teeth and means for. fastening the teeth to said supports and consists inemploying for the manufacture of said artificial members a chromium-nickel-steel alloy containing about 18 to 23 per cent chromium, 5 to 10 per cent nickel and 0.1 to 0.4 per cent carbon. These alloys which reslst oxidizing and deteriorating influences of the; organism practically to the same degree as precious metals such as platinum, gold and silver, .but which are considerably cheaper than the latter, are capable not only to form substitutes of these precious metals, but they surpass them in many respects.
The tensile strength and hardness of chromium-nickel-steel, both of V which are throughout greater than those of precious metals, render itpossible to'construct artificial bone portions, mouth plates and other elements of artificial sets of teeth as well as orthodontic apparatus for internal adaption very light without impailing their strength and durability. This is a considerable advantage over precious metals whose scarcity and high price has in many instances caused too light a construction 01" the artificial BIGIIIbQIS. to render them durable. Moreover the use of chromium-nickelthe further-"advantage that owing to their comparatively small value, no regard need be taken of the waste which occurs during manufacturing so that the manufacturing methods may be materially simplified. It is also important that chromiumnickel-steel alloys of this character when used in artificial sets of teeth have no taste and further that their ex ansion coeficient liind of porcelain to be used internally for] human or animal steel alloys of the characterdescribed has Specification of Iietters Patent. Patenfi gdl July 4 1922 7 which is used for artificial teeth. Thus for I instance, when chromium-nickel-steel pins are burned into the porcelain crowns of teeth, the latter are not. cracked and split by undue expansion of the ins. v
Furthermore, chromium-nlckel-steel alloys when attached to artificial teeth by burning processes or the like, will not discolor the porcelain which is otherwise the case with every metal except latinum.
-The annexed drawlng shows for illus'tration, an upper plate in section, the palate .part a of which together with the hook b is made of the alloy of the specified character. The fastening pins 0 connecting the porcelain front a? of the teeth with the palate part a; are-also made of thisalloy.
Claims.
1. As a new article of manufacture a porcelain tooth element, a supporting structure for said element and a connecting chromium-nickel-steel pin for attaching said porcelain element to said structure, said pin havlng the composition chromium -18 to 23 per cent, nickel 5 {to 10 per cent, carbon .1 to .4 percent.
2. A new article of manufacture comprising a porcelain tooth element having a burnt-in chromium-nickel-steel pin of the composition chromium 18 to 23 per cent, nickel 5 to 10 per cent, carbon .1 to .4 per cent.
3. In. combination with a tooth, a dental support for said tooth, said support made up of the physio-logically inert chromium nickel-steel alloy, having the composition chromium 18 to 23 per cent, nickel 5 to 10 per cent, carbon .1 to .4'per cent.
4:. As a new article of manufacture a porcelain crown element having a burnt-in chromium-nickeLsteel pin of the composition' chromium 18 to 23 per cent, nickel 5 to 10 per cent, carbon .1 to .4 per cent.
- 5. As a new article of manufacture, an artificial member to be used internally for living organisms made up of a chromiumnickel-steelalloy having the composition chromium 18 to 23 per cent, nickel 5 to 10 per cent, carbon .1 to .4' er cent. FRIEDRICH HA PTME.
