This analysis compared the precementation quality of metal ceramic restorations made from different alternative alloys after they had been returned from the central dental research laboratory. Ticon, Micro-Bond N/P2, Ceramalloy II, and W-1 materials were evaluated by use of 11 well-defined criteria and for overall performance. The evaluations were compared with those of Olympia, a gold-containing alloy, which served as the control. The results showed statistically significant differences between Olympia alloy and some of the alternative alloys for six of the 11 criteria. These differences, however, were not sufficient to be considered clinically significant (clinically detectable). In the comparison of their overall performances no statistically significant differences were found.
该分析比较了从中央牙科研究实验室返回后，由不同替代合金制成的金属陶瓷修复体的粘固前质量。使用11项明确的标准对Ticon、Micro-Bond N/P2、Ceramalloy II和W-1材料进行了评估，并评估了其整体性能。将这些评估结果与用作对照的含金黄合金Olympia的评估结果进行了比较。结果显示，在11项标准中的6项上，Olympia合金与一些替代合金之间存在统计学上的显著差异。然而，这些差异不足以被认为具有临床意义（临床上可检测到）。在比较它们的整体性能时，未发现统计学上的显著差异。
