An alloy is bio-compatible when it is compatible with a living organism. To be "compatible" is to be capable of co-existing with another element. In medical terms, it means: which does not cause immunological rejection on behalf of the host.

    In dentistry, the alloys to be used intra-orally must be bio-compatible, in order to ensure that they will not provoke any rejection or tissue inflammation, and that the organism will not be affected by their presence.

    In order to prove scientifically the bio-compatibility of the alloys it manufactures, BEGO decided to have all of its alloys tested by private and independent research institutes. A protocol was therefore written and the research projects were entrusted to worldwide renowned firms.

    The German corporation Cytotest Research GmbH & Co was asked to test the cytotoxic potential of BEGO's alloys.  The Swiss company R.C.C. (Re- search & Consulting Company)  was asked to make certain that the alloys, after having successfully undergone the cytotoxicity tests, would not cause either coetaneous irritation nor allergic  sensitivity.

    Finally, on a given alloy, a total of two tests must be conducted by two different research institutes - independent from one to another and having no links with the alloy's manufacturer.




  We at Peters Dental Ceramic Studio take the issue of biocompatibility very seriously.  With wide media coverage, the patient is now a very wise consumer and is concerned about what is being placed in their mouth.

    While researching the different alloy companies available to us, we were looking for a  company that performed extensive research and testing on all their alloys. BEGO, a company with over 100 years in the dental alloy field is the only company that sends all their alloys for independent testing for biocompatibility and toxicity.

    With every case that is sent out from our laboratory, a certificate of biocompatibility is provided for the practitioner and the patient. This is one of our quality control measures to ensure that the patient is receiving a  safe restoration.

    We have also invested heavily in the purchase of  a  state of the art pressure induction casting machine which ensures the perfect melt of every alloy. This guarantees that the alloys will not be over heated and its properties altered, hence guaranteeing biocompatibility. Here again, a certificate is provided showing the results of the casting.

    A laser welder was also added to our laboratory to ensure that all welds are done with the same alloy rather than using solders which would alter the safety of the alloy.

    Safety for the patient as well as for our technicians handling the materials is of great concern to us, and we have done everything possible to ensure that the best quality product will leave our laboratory.

If you would like  more details on how these tests were carried out please contact us and we will send out the research protocol booklet.
