摘要: The purpose of this study was to evaluate the fracture resistance Nd:YAG laser-welded cast titanium (Ti) joints with various clinical thicknesses and welding pulse energies. A four-point bending test used assess effects specimen (1-3 mm) energies (11-24 J) on Ti dental joints. Fracture evaluated in terms ratio number fractured specimens tested specimens. As for frequencies, they were compared using Cochran-Mantel-Haenszel test. Morphology observed a scanning electron microscope. Results showed that decreasing thickness and/or increasing energy, i.e., welded area percentage, resulted an increase joint. Where occurred, site would be at center weld metal.
