Metal free restorations

The modern dentistry try after to use dental material in the mouth that are tissue-friendly, bio-compatible and do not harmful of the human organism. The human body will not recognize them as strange substances; thereupon it will not refuse. These materials are not supposed to pile up in different parts of the body nor to cause diseases. Maybe you have already heard different opinions connection with amalgam that has averred to be the most stable substance so far, but it advances also the question whether quicksilver as a heavy metal can cause destructive reactions in the human body when it breaks down from a filling.

It is a fact that furthermore amalgam (which is an alloy and contain quicksilver and several other metals) also other metals used in dentistry have confirmed to cause allergy and other disease. A perfect and known example for this is nickel. It is generally that the new custom is dentist try to obviated use of these harmful metals, which is not accurately simple as it is extraordinarily difficult to find practicable materials with as prosperous characteristics (for example flexibility strength) that are alike to those of metals and that are requisite in the case of certain reparations (fixed partial denture, when missing tooth or teeth have to be supplicated). Such a substance is plastic attached with glass strings (Belle Glass that has very alike characteristics to tooth tissue.)

Another good example the long-used porcelain that can be worked out in several different methods and with different technologies thus is opportune for several kinds of reparations. Neither of them is, nevertheless, appropriate for filling bigger spaces. Circonium dioxide is the revolutionary and the best convenient at present therefore the best substance to use for building longer fixed partial dentures. Its hardness and somatic characteristics top those of metals. Moreover the used technology to fit for these reperations will specifically be a leading method in the 21st century.
