| Abstract: | Objective To discuss the rationality of design of hinge extracoronal attachment. Methods In this experiment, the stress distribution of the L-shape sphere attachment was analyzed by EF, and its strength was also tested. Results Through FEA, the highest value of stress is 321.8MPa, which is found at the angle of the L-shape sphere at- tachment. Conclusions The strength of the hinge attachment can meet the clinical demand. |
