Abstract

Purpose: To evaluate the effect of universal adhesives on the long-term bond strength to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP).

Materials and methods: Polyethylene tubes filled with composite cement containing 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) were adhesively luted to 60 fully sintered Y-TZP slabs (7 x 7 x 2 mm) with or without (control) previous application of a 10-MDP-based adhesive (All Bond Universal, Bisco) - ABU; Clearfil Universal Bond Quick, Kuraray Noritake - CUB; Scotchbond Universal Adhesive, 3M Oral Care - SUA) on the zirconia surface. The bonded specimens were stored in water for 24 h, 6 months, or 1 year and subjected to microshear bond strength testing. The data were analyzed by one-way ANOVA and Tukey's test (p < 0.05). The contact angle was measured after adhesive application to evaluate surface wettability. The adhesive-treated specimens were analyzed with x-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) for chemical characterization.

Results: The application of a 10-MDP-based adhesive significantly improved bond strength of composite cement to zirconia when compared to the control group (no adhesive application) (p < 0.05). One-year water storage significantly decreased bond strength for ABU- and CUB-bonded specimens, but not for SUA-bonded specimens. The analysis by XPS and ToF-SIMS showed peaks of carbon, phosphorus, and silicon in all adhesive-treated specimens.

Conclusions: One-year water storage affected the bond strength of composite cement to zirconia when All Bond Universal or Clearfil Universal Bond Quick were used.

通用粘合剂对氧化锆长期粘接强度的影响

目的：评估通用粘合剂对钇稳定四方氧化锆多晶体（Y-TZP）长期粘合强度的影响：将装有含 10-甲基丙烯酰氧癸基磷酸二氢酯（10-MDP）的复合粘合剂的聚乙烯管与 60 块完全烧结的 Y-TZP 板（7 x 7 x 2 毫米）粘接在一起，并在氧化锆表面涂抹或不涂抹（对照组）以 10-MDP 为基础的粘合剂（All Bond Universal，Bisco）- ABU；Clearfil Universal Bond Quick，Kuraray Noritake - CUB；Scotchbond Universal Adhesive，3M Oral Care - SUA）。粘结后的试样在水中分别存放 24 小时、6 个月或 1 年，然后进行微剪切粘结强度测试。数据分析采用单因素方差分析和 Tukey 检验（P < 0.05）。使用粘合剂后测量接触角以评估表面润湿性。用 X 射线光电子能谱（XPS）和飞行时间二次离子质谱（ToF-SIMS）分析粘合剂处理过的试样的化学特性：与对照组（未使用粘合剂）相比，使用基于 10-MDP 的粘合剂可显著提高复合水泥与氧化锆的粘结强度（p < 0.05）。ABU和CUB粘结试样一年的水贮存会明显降低粘结强度，而SUA粘结试样则不会。XPS 和 ToF-SIMS 分析显示，在所有粘合剂处理过的试样中都出现了碳、磷和硅的峰值：结论：使用 All Bond Universal 或 Clearfil Universal Bond Quick 时，一年的储水会影响复合水泥与氧化锆的粘接强度。
