Best conditions for plating SnO2 on pure titanium of titanium-polymerization porcelain restoration by Sol-gel method
摘要
Abstract
Objective To explore the best conditions for plating SnO2 on pure titanium of titanium-polymerization porcelain restoration by Sol-gel method.Methods A total of 80 pieces of pure titanium specimen were selected.Of which 30 pieces were given sandblasting and divided into five groups, then they were respectively coated with 0.20, 0.30, 0.37, 0.50 and 0.60 mol/L tin-containing sol, followed by heating treatment under 300℃, 500℃and 700℃.In 0.20 mol/L sol plating surface, the metal film almost did not exist, in 0.6 mol/L sol plating surface, metal film crack was too large, and thin film almost fell off;in 0.30, 0.37 and 0.50 mol/L sol plating surface, metal film was in good condition, with mi-nor cracks and was uniform.The other 50 pieces of pure titanium specimen were divided into ten groups, with five pieces in each group.In addition to the control group (group A), the other pieces were divided into three large groups (15 pieces in each group), respectively, and then were coated with 0.30, 0.37 and 0.50 mol/L sol, followed by heating treatment un-der 300 ℃(group B1, B2, B3), 500 ℃ (group C1, C2 ,C3) and 700 ℃ (group D1, D2, D3) respectively.Then shear bond strength was measured by universal testing machine, titanium surface topography was observed under emission scanning electron microscopy ( SEM) , and X-ray diffraction analyzer was used to analyze interface components.Results In the group D1, the specimen surface was smooth, metal film was compact and uniform, only a trace of tiny crack.In oth-er groups, titanium surface was uneven, and with crack.The shear bond strength of group D1 was significantly higher than that of other groups (all P<0.05).A lot of SnTi3, SnO2 and TiO2 was found in metal film of group D1, and the content was higher than the other groups (all P<0.05).Conclusion 0.3 mol/L sol and 700℃heat treatment are the best con-ditions for plating SnO2 on pure titanium of titanium-polymerization porcelain restoration.关键词
