Relationship among Schneiderian Membrane, Underwood's Septa, and the Maxillary Sinus Inferior Border

Abstract

It is suggested that Underwood's septa may be the reason for the thinness of the Schneiderian membrane. However, future studies among larger groups are necessary for confirming the finding by using well-designed clinical studies.

Accuracy of Schneiderian membrane thickness: a cone‐beam computed tomography analysis with histological validation

“…It has also been demonstrated that males had thicker membrane thickness (0.74 mm) when compared to females (0.34 mm) (Cakur et al. ). Additionally, Shanbhag et al.…”

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).…”

Primary implant stability in a bone model simulating clinical situations for the posterior maxilla: an in vitro study

“…The density of the block simulating maxillary cancellous bone was determined to be 0.32 g/cm 3 with reference to previous studies [1516]. For the cortical layer of the maxilla, epoxy sheets (Sawbones; Pacific Research Laboratories Inc., Vashon, WA, USA) filled with short fibers were constructed to a thickness of 1 mm, considering previous studies that showed cortical bone thickness (1.49±0.34 mm) and the inferior border thickness of the maxillary sinus (0.86±0.21 mm) [1718]. The dimensions of each block were 3 cm×3 cm×the designated height.…”
