News from Haikou on March 27 ' Reporter Chen Xin) "Put nickel chromium roast porcelain which not good influence will there behind the tooth? " "What differences does the roast porcelain tooth of stainless steel tooth and nickel chromium have? " Recently, " nickel chromium roast porcelain tooth " that this newspaper opens The hot line 66810862 prevails, a lot of consumers come to consult the security question of the nickel chromium roast porcelain tooth one after another.
The incoming telegram of Mr. Chen in Chengmai reflects, present gingivae red swelling behind installing the nickel chromium roast porcelain tooth oneself, irritated, can not eat the situation of going with rice etc., it is said the nickel chromium roast porcelain tooth suspects that will cause nephropathy, add for these days, his gingivae is still bleeding, so does not rest assured about the nickel chromium roast porcelain tooth very much. These days, his report in paying close attention to, hope the national related departments can have an authoritative statement to come out.
"It puts the intersection of nickel and the intersection of chromium and roast the intersection of porcelain and tooth to be kind and the intersection of doctor and technology have, concern certainly.

He introduces to the reporter, though it has potential harmfulness that the experiment shows nickel, but not presented and used the case report which cause nephropathy and tumour of roast porcelain tooth of nickel chromium on clinic, so the nichrome is still used on clinic extensively. For example, the nickel chromium roast porcelain alloy that this institute uses is Germany KeraN medical alloy, the outer surface that the nichrome precededs at bottom is the dense roast porcelain floor, have limited nickel element and buccal direct contact objectively. In addition, tooth of a specialized one body prepare and high-level the intersection of making and craft and tight edge close the result, the chance that heavy metal ion such as nickel, chromium release in a large amount is extremely low in the roast porcelain tooth.
But in the complicated oral cavity environment, because the temperature is changed, such factors as sour alkalinity change, saliva enzymolysis, electrolytic chemistry corrode, using in the course for a long time inevitably has nickel element to permeate and release out. But a small amount of nickel will have danger on human body, prerequisite that nickel is poison whether human body suck or take in high nickel of density.

Irritated phenomenon the intersection of whole body and complication of nichrome one of, show as some mucomembranous bleb, rotten and the intersection of skin and urticaria mainly. So propose the person of the irritated physique does the nickel chromium roast porcelain tooth prudently, but choose the precious metal or not include the metal the whole porcelain to repair.
