摘要
目的:测试比较3种烤瓷合金(BioHeradorN贵金属烤瓷合金,TILITE含钛医学合金,HeraeniumS不含铍烤瓷合金)的金瓷结合强度,研究预氧化处理对烤瓷合金金瓷结合强度的影响。方法:制作蜡片30个,随机分为3组,每组10件。采用BellavesSH包埋料真空包埋、铸造,铸件最终尺寸为25mm×3mm×0.5mm金属片。上瓷前对铸件按实验要求进行处理,然后上瓷、烧烤。测试金瓷结合强度。结果:3种烤瓷合金金瓷结合强度由大到小依次为BioHeradorN合金,TILITE合金、HeraeniumS合金。预氧化处理可增加BioHeradorN合金、TILITE合金的金瓷结合强度,而对HeraeniumS合金的金瓷结合强度无重要影响。结论:贵金属烤瓷合金的金瓷结合强度大于非贵金属烤瓷合金的金瓷结合强度,BioHeradorN合金、TILITE合金上瓷前应作预氧化处理,以利于提高合金的金瓷结合强度。HeraeniumS合金上瓷前可不作预氧化处理。
PURPOSE: To compare the metal-ceramic bonding strength of different ceramic alloies. METHODS: 30 wax sheets were divided into 6 groups at random.Each group included 5 sheets.After being invested conventionally with Bellaves SH,the samples were casted and fused with porcelain.The metal-ceramic bonding strength was evaluated. RESULTS: The highest bonding strength was found in Bio Herador N alloy, and then in TILITE alloy and Heraenium S alloy respectively. Bio Herador N alloy and TILITE alloy all had significant differences of the bonding strength before and after treatment (P<0.05). There was no significant differences in the bonding strength of the Heraenium S alloy after treatment (P>0.05). CONCLUSION: The bonding strength of precious metal-ceramic was higher than that of non- precious metal-ceramic.Pre-oxygen treatment can improve the metal-ceramic bonding strength of Bio Herador N alloy and TILITE alloy,but it had no effect on the metal-ceramic bonding strength of the Heraenium S alloy.
