    Abstract:
    The strength of the teeth with subclinical fractures which are cured with miniature SMA staples is analysed and studied using bending theory, tensile theory and experimental method in material strength. It is included that the strength of teeth with subclinical fractures which are cured with miniature SMA staples is 2236 symbol 177 "Symbol" s 10.5眪 1654 N, the strength of teeth with subclinical fractures which are not cured with miniature SMA staples is 1348 symbol 177 "Symbol" s 10.5眪 947 N, and that the strength of teeth with subclinical fractures which are cured with miniature SMA staples is obviously greater than that of the teeth with subclinical fractures which are not cured with miniature SMA staples（P < 0.05）.
