Schneiderian Membrane Thickness and Clinical Implications for Sinus Augmentation: A Systematic Review and Meta‐Regression Analyses

“…Finally, 38 studies were eventually excluded for not meeting the strict inclusion criteria, and 31 studies that reported SMT were considered for qualitative analysis (Table 1). 12,13,15‐18,23‐47 Those studies reporting range or unclear data were excluded for the quantitative analysis (Fig. 1).…”

“…Overall, 19 studies 13,15,17,18,23‐37 fulfilled the inclusion criteria for quantitative assessment. Mean ± SE SMT was 1.17 ± 0.1 mm (95% confidence interval [CI] = 0.89 to 1.44).…”

“…Other extracted parameters did not show consistency to be analyzed quantitatively. Ten studies 13,15,18,23‐25,32,35‐37 reported age as a covariate for SMT. High heterogeneity was found among studies (weighted SSQ for error = 218.71; df = 8; P <0.001).…”

“…Studies reporting smoking (n = 8 to be meta‐analyzed) 13,18,23,25,30,35‐37 showed high heterogeneity (weighted SSQ for error = 37.48; df = 6; P <0.001). As such, the regression analysis from the random‐effects model demonstrated that, even in the lack of statistical significance, there is a near‐trend significance ( P = 0.11).…”

“…Six studies reported the influence of SMT on membrane perforation/tearing and could therefore be meta‐analyzed 13,23,29,30,35,36 . Mean membrane perforation was 14.94%.…”
