[Effect of gilding technique on the element release of beryllium ion from Vera Bond titanium alloy].

ABSTRACT

OBJECTIVE: To research the effect of gilding technique on the element release from Vera Bond Ti alloy exposed to artificial saliva. METHODS: To divided experimental group into 4 groups common used Ti porcelain crown (controlling group, A1), polished Ti porcelain crown (polished group, A2), gilded Ti porcelain crown (gold-plating group, A3), gilded Ti porcelain crown prolonged 50% (gold-plating prolonged 50% group, A4). T measure the quantity of beryllium ion in artificial saliva after 1 month, 3 months and 6 months by means of ICP-AES. So the efect of released beryllium ion with different treatments and the role of different times with the same treatment were compared. RESULTS: The quantity of released beryllium ion was statistic significant among different treatments. The quantity of released beryllium ion was gradually increased with the same treatment. The speed of released beryllium ion was gradually decreased with the same treatment. CONCLUSION: The gilding treatment can decrease the quantity of beryllium ion which released from Ti porcelain crown,and improve the biocompatibility.
