| 摘 要： | 目的探讨合适的渗透陶瓷表面处理方式。方法以不同的表面处理为影响因素,将陶瓷片分为4组,采用水平推式剪切强度试验法,所得试验数据经统计学分析,考察不同表面处理方式与常规Bis-GMA类树脂粘接剂间的结合强度。结果HF加硅烷、喷砂加硅烷组粘接抗剪强度24h略增加,但差别无统计学意义,在模拟口腔环境下30d后,抗剪强度下降十分明显,而热学硅涂层加硅烷组24h后增加明显,与其它组对照差别有统计学意义(P<0.05),30d后抗剪强度略有下降。结论热学硅涂层加硅烷是渗透陶瓷粘接面的较好的处理方法。

| Abstract: | OBJECTIVE: The adequate surface conditioning method for GI-II glass infiltrated alumia ceramic was investigated. METHODS: The test specimens were divided into 3 groups (A. HF + silicon, B. sandblasting + silicone and C. thermal silicoating + silicone). Shear bonding strengths of porcelain bonded to dentin were tested. RESULTS: The bond strength of group A and B slightly increased after one day but decreased sharply after 30 days. However, no statistical significance was observed. The group C showed a pronounced enlargement of bond strength after one day and had a durable bond after 30 days' thermal cycling. It is statistically significant when group C was compared with group A and B. CONCLUSION: It can be inferred that silicoating method be a better way for glass infiltrated alumia ceramic bonding. |
