Abstract: Objective: Our aim was to evaluate the biocompability of porcelain compounded with nanostructured material. Methods：The proliferation of the NIH3T3 cells were investigated using a tetrazolium-based colorimetric assay(MTT assay).Maceration extract of four tested materials were added into culture plate .The samples were tested with ultraviolet spectrophotometer in 490 wavelength at 1，3，5，7 days after the addition of extract. Morphology of these cells was also observed with phase-contrast microscope. Results： There was no obvious difference among three kinds of prosthetic materials in the optical absorbance and the cells growing in the extract showed normal morphology. Conclusion: The toxicity graduation of the porcelain compounded with nanostructured material is 0. This material has a good biocompability and can be used clinically.
