LONG-TERM EFFECT OF SURFACE ROUGHNESS AND PATIENTS' FACTORS ON CRESTAL BONE LOSS AT DENTAL IMPLANTS. A SYSTEMATIC REVIEW AND META-ANALYSIS
higher mean bone loss in patient groups with a periodontal history compared to periodontally healthy patients (z = 3.1822, p = .0015) (Figures 5 and 6).
Figure 5: Forest plot for additional bone loss (expressed as positive value in mm) between patient groups with a periodontal history (experimental group) and without a periodontal history (control group) including one study using implants with a minimally rough surface and two studies using a rough surface
Figure 6: Forest plot for additional bone loss (expressed as positive value in mm) between patient groups with a periodontal history (experimental group) and without a periodontal history (control group) reduced to the two studies using implants with a rough surface
Heterogeneity I2 = 90.8 of the studies comparing smoking and non-smoking with respect to bone loss was significant (Q = 32.55, df = 3, p < .0001) and t2 high (70.4%). The random effects model showed a significant difference in mean bone loss between smokers and non-smokers (z = 2.3008, p = .0214) (Figure 7).
