摘要
目的:观察喷砂、酸蚀及硅烷偶联剂等表面处理方法对热压铸陶瓷,玻璃渗透陶瓷和氧化锆陶瓷与不同种粘结剂的粘结强度的影响。方法:样本分为热压铸陶瓷组,渗透陶瓷组和氧化锆陶瓷组。分别应用不同表面处理方法和粘结剂,测其剪切强度。结果:方差分析表明,热压铸陶瓷组中酸蚀涂硅烷树脂粘结组粘结强度最高,渗透陶瓷组中喷砂玻璃离子粘结组粘结强度最高,氧化锆陶瓷组中喷砂玻璃离子粘结组粘结强度最高。结论:应用常规树脂粘结剂粘固热压铸陶瓷修复体取得较好的粘固效果,采用酸蚀和硅烷偶联剂的表面处理,可取得最大粘结强度。
Objective： To compare shear bond strength of different luting cements to several porcelain after different porcelain surface treatments. Methods： Three kinds of ceramic specimens （Empress Ⅱ, GI-Ⅱ and Cercon） were investigated and each kind of specimen was divided into four groups respectively. The four groups were treated with sand-blasting plus silanation, etching plus silanation, respectively. Then two kinds of luting cements were used to bond the ceramic pieces and the shear bond strengths were measured. Results： The results showed that in Empress group the shear bond strength of specimen treated with etching＋silanized and Vita bonding was higher than other specimens and in GI-Ⅱ and zircon group the shear bond strength of specimen treated with sand-blasting and cement was higher than other specimens. Conclusions： It is suggested that surface conditioning using etching plus silanation and Vita bonding can remarkably improve the shear bond strength of Empress Ⅱ ceramic.
