Abstract:
Objective To study the clinical feasibility of micrometer method and thin carbon paper method in the marginal fitness of crown.Methods 10 ex vivo teeth were selected to be restored by Nickel-Chromium alloy PFM crown.Selected 6 measurement sites on shoulder in each ex vivo teeth.Micrometer method,thin carben paper method and SEM method were used to measure.and the data were analyzed by SPSS 13.0.Results 5 data in micrometer method and 6 data in thin carbon paper method were different to SEM method.The disparity was not statistically significant(t=0.392 and t=0.543).Conclusion Micrometer method and thin carbon paper method were two facility quantization measurements to the marginal fitness of crown.They had satisfied to effect in clinic.
