摘要

目的:研究不同粘结剂和釉料用量对单片氧化锆(MZ)与间接复合材料(IC)剪切粘结强度(SBS)的影响。材料和方法:五种不同的粘结剂(G-Premio Bond [GP];Tokuyama Universal Bond [TU];铈锆键;Clearfil Ceramic Primer Plus [CCP];Z-Prime Plus [ZP])应用于共200个MZ盘形试样(n = 100个釉面和100个非釉面)。然后，一半标本进行热循环，另一半不进行热循环(每亚组n = 10个标本)。实验装置按ISO TR 11405标准分为两部分制备。将包埋在丙烯酸树脂中的试样以0.5 mm/min的十字速度分别放入实验装置和万能试验机中。采用Mann-Whitney U检验和Kruskal-Wallis检验进行统计分析。然后进行Bonferroni校正，以P < 0.05的检验结果为有统计学意义。结果:ZP或CCP均能显著提高SBS;而GP、TU、SZ组均无显著影响。除釉面GP外，各粘结剂组SBS均显著降低(P = 0.16)。在所有条件下，使用GP和TU时SBS最高。结论:这些研究结果表明，可以推荐GP和TU作为MZ和IC之间更好的粘合剂。

Effects of Different Bonding Agents on the Shear Bond Strength Between Monolithic Zirconia and Indirect Composite.

Purpose: To investigate the effects of different bonding agents and application of glaze on the shear bond strength (SBS) between monolithic zirconia (MZ) and indirect composite (IC).

Materials and methods: Five different bonding agents (G-Premio Bond [GP]; Tokuyama Universal Bond [TU]; Signum Zirconia bond [SZ]; Clearfil Ceramic Primer Plus [CCP]; Z-Prime Plus [ZP]) were applied to a total of 200 MZ disk-shaped specimens (n = 100 glazed and 100 nonglazed). Half of the specimens then underwent thermocycling and the other half no thermocycling (n = 10 specimens each subgroup). The experimental setup was prepared as two pieces according to the ISO TR 11405 standards. Specimens embedded in acrylic resin were placed into the experimental setup and a universal testing machine at a crosshead speed of 0.5 mm/minute. Mann-Whitney U test and Kruskal-Wallis test were used for statistical analyses. Bonferroni correction was then performed, and test results with P < .05 were accepted as statistically significant.

Results: The application of glaze significantly enhanced SBS when ZP or CCP was used; however, it did not have any significant effect when GP, TU, or SZ were used. Thermocycling significantly decreased the SBS in all bonding agent groups except GP specimens with glaze (P = .16). The highest SBS in all conditions was noted when GP and TU were used.

Conclusions: These findings suggest that the bonding agents GP and TU may be recommended for better bonding between MZ and IC.

期刊介绍： Official Journal of the European Association for Osseointegration (EAO), the International College of Prosthodontists (ICP), the German Society of Prosthodontics and Dental Materials Science (DGPro), and the Italian Academy of Prosthetic Dentistry (AIOP) Prosthodontics demands a clinical research emphasis on patient- and dentist-mediated concerns in the management of oral rehabilitation needs. It is about making and implementing the best clinical decisions to enhance patients'' quality of life via applied biologic architecture - a role that far exceeds that of traditional prosthetic dentistry, with its emphasis on materials and techniques. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today''s prosthodontist, clinician, and educator alike. The editorial board is composed of a distinguished team of leading international scholars.
