Influence of Insertion Torque on Clinical and Biological Outcomes before and after Loading of Mandibular Implant-Retained Overdentures in Atrophic Edentulous Mandibles

Figure 4

(a) Dispersion diagrams showing the correlations between the probing depth (PD) and time since edentulism and (b) between the PD and bone atrophy according to the anterior mandibular height. (c) Box-plot showing the PD according bone type, bone atrophy, and time since edentulism. Different letters indicate statistically significant differences; the estimates given are standardized coefficients with respective 95% confidence intervals.
