Regarding displacement under loading, a one-way analysis of variance (ANOVA) was used to investigate statistically significant differences between the loading sites. A three-way ANOVA was used to investigate statistically significant differences in three-dimensional implant displacements under loading conditions. The assessment site, dental formula, and loading point were used as intra-subject parameters.

Additionally, a three-way ANOVA was used to investigate statistically significant differences in equivalent stress values. The boundary conditions, dental formula, and loading point were used as intra-subject parameters.

To assess the reproducibility of each of the models, the coefficient of variation (CV) was calculated for implant displacement under loading conditions and the equivalent stress values from each of the three experimental and FEA models. To assess the validity of the FEA models, Pearson’s correlation coefficient was calculated for implant displacement under loading conditions in the experimental model and the contact model. Statistical processing was performed using PASW Statistics 18 (SPSS, Tokyo, Japan).
