Fatigue behavior of the titanium bars is of utmost importance for the safe and reliable operation of dental implants and prosthetic constructions based on these implants. To date, however, only few data are available on the fatigue strength of dental prostheses made with electric resistance welding and laser welding techniques. This in-vitro study highlighted that although the joints made with the laser welding approach are credited of a superior tensile strength, joints made with electric resistance welding exhibited double the minimum fatigue strength with respect to the joints made with laser welding (120 vs 60 N).
钛棒的疲劳行为对于基于这些种植体的牙种植体和修复结构的安全可靠运行至关重要。然而，迄今为止，关于采用电阻焊和激光焊技术制作的牙修复体疲劳强度的数据很少。这项体外研究强调，尽管激光焊接方法制作的接头具有更高的拉伸强度，但电阻焊接制作的接头的最小疲劳强度是激光焊接制作接头的两倍（120对60 N）。
