固位种植固定义齿(FPD)的主要缺点是修复困难。因此，在这些病例中通常使用的临时粘固剂的固位强度是一个重要的考虑因素。本研究评估了4种临时粘固剂对2个种植体或4个种植体支持的FPD的粘接强度。在两种类型的FPD中，NOGEOL粘结剂的固位值最低。在所有测试的粘固剂中，改良剂被证明是最坚固的。TEMP Bond NE和Temp Bond对于2-种植体FPD显示显著不同的值(P<；0.05)，但对于4-种植体模型没有显著差异。根据研究结果，可以得出结论，当预期移除临时粘结的上部结构时，Ngenol似乎更适合于2-和4-种植体支持的FPD的粘结。
The major disadvantage of cement-retained implant-supported fixed partial dentures (FPDs) is difficulty in retrievability. The retentive strengths of the provisional luting agents usually employed in these cases are therefore an important consideration. This study evaluated the cement failure loads of 4 provisional luting agents used for the cementation of FPDs supported by 2 implants or 4 implants. Nogenol luting agent exhibited the lowest retentive values in both types of FPD. ImProv proved to be the most retentive cement of all tested. Temp Bond NE and Temp Bond presented significantly different values (P < .05) for the 2-implant FPD, but not for the 4-implant model. On the basis of the study results, it may be concluded that Nogenol appears to be more appropriate for cementation of both 2- and 4-implant-supported FPDs when removal of the provisionally cemented superstructure is anticipated.
