One of the concerns of the dental surgeon in the realization of any operational act is the durability of this one. The mechanical resistance of the provisional prostheses contributes in a large part to the durability of those. The resins in general, have weak mechanical properties. The purpose of this study is to evaluate the resistance in inflection of temporary bridges reinforced with glass fibre. To remedy the weak mechanical properties of resins, we thought in this study, to reinforce them with glass fibres. For this purpose, we realized with two different resins, four groups of temporary bridges of 3 elements, including two groups reinforced fibreglass and the others not. Tests of inflection 3 points have been made on these bridges and resistance to fracture was analysed. The statistical tests showed a significant difference in four groups with better resistance for the reinforced bridges.
在实施任何手术操作时，牙科外科医生所关心的问题之一就是该操作的持久性。临时修复体的机械抗力在很大程度上决定了其持久性。一般来说，树脂的机械性能较弱。本研究的目的是评估用玻璃纤维增强的临时桥的抗弯曲性能。为了弥补树脂较弱的机械性能，我们在本研究中考虑用玻璃纤维对其进行增强。为此，我们用两种不同的树脂制作了四组由三个部件组成的临时桥，其中两组用玻璃纤维增强，另外两组未增强。对这些桥进行了三点弯曲测试，并分析了其抗断裂性能。统计测试表明，四组之间存在显著差异，增强后的桥具有更好的抗力。
