Biocompatibility1. Introduction

Bloomzir is a yttrium-stabilized zirconium oxide (Y-TZP). Y-TZP is considered to be a highly compatible material, which has already been used in medical applications such as artificial hip joints and dental implant abutment.
The biocompatibility results recorded for Y-TZP also apply to Bloomzir blocks.


2 .Chemical durability

Dental materials are exposed to a large variety of pH values and temperatures in the oral cavity. Chemical durability is therefore a highly important prerequisite for all dental materials. According to Anusavice1, ceramics are among the most durable dental materials.

Chemical durability according to ISO 6872:

  Chem. Solubility
[?g/cm2]		 Limit value according to
standard [?g/cm2]
Bloomzir 2.5 < 100

The chemical solubility of Bloomzir block is far below the limit value according to the relevant standard.
3.Biocompatibility of yttrium-stabilized zirconium oxide2
The following tests were conducted on Bloomzir block
Tests into vitro: Cytotoxicity (cell cultures)
Chromosome damage (mutagenicity test, Ames test)
Haemolysis
Test into vivo: (with rabbits, mice, guinea pigs, and sheep)
Haemolysis
Acute toxicity (systemic)
Irritation (intracutaneous)
Sensitization
Pyrogenicity test

Test report:
(This report is supplied by National Food& Drug Administration Medical Devices Quality supervision and testing centre of Peking University)

Test item Test criteria Test result Test compliance
Bending strength ?900Mpa 1230 Complied
Chemical solubility ?100ug/cm-2 2.5ug/cm-2 Complied
Radioactivity ?0.2Bq/g 0.015 Bq/g Complied







Biocompatibility		 Cytotoxicity test Cytotoxicity should be grade 0. Cytotoxicity is 0; there is no Cytotoxicity on specimen. Complied
Short-term systemic toxicity test This material shall be no toxicity. During the test, no obvious differences were found between the test sample and the control group. It shows the test sample has no systemic toxicity. Complied
Sensitization test (Delayed-type hypersensitivity test ) The test sample should be no sensitization. The reaction grade of 10 animals? skin scored 0, less than 1. This indicates the test sample has no sensitization. Complied
intracutaneous irritation test No irritation Irritation index: less than 1; the test sample has no intracutaneous irritation. Complied

None of these tests showed a potential of Bloomzir Block to cause adverse health effects.

4.In vitro toxicity /in vitro genotoxity

Josset et al3 investigated the biocompatibility of two implant materials ? zirconium oxide and aluminum oxide in osteoblast cell cultures. Both materials were reported to have neither a toxic nor a genotoxic

5.Radioactivity

The radioactivity of Bloomzir block was measured at the research center in China. The measured value of 0.015 Bq/g is much lower than the maximum value of 0.2 Bq/g permitted by ISO 6872.

6.Conclusion

In the view of the present data and today?s level of knowledge, it can be stated that Bloomzir block does not feature a toxic potential. If the material is used according to the Instructions for Use, it does not pose any risk to the health of patients, dental technicians, and dentists.
