The Relationship between Maxillary Sinus Lateral Wall Thickness, Alveolar Bone Loss, and Demographic Variables: A Cross-Sectional Cone-Beam Computerized Tomography Study

Abstract

Objectives: Sinus floor elevation and augmentation surgery is widely used as a reliable procedure to increase insufficient bone height in the posterior maxillary area. The purpose of the present clinical study was to determine the associations between periodontal bone loss (PBL), maxillary sinus lateral bone wall thickness, age, and gender using cone-beam computerized tomography (CBCT). Materials and Methods: The current retrospective study consists of 716 maxillary sinus CBCT images of 358 patients. The CBCT scans were assessed to detect the relationship between lateral wall thickness and PBL. ANOVA and Student t test analysis were used to determine the influence of PBL on sinus lateral wall thickness. Results: Sinus lateral wall thickness was significantly associated with PBL (p < 0.05) at 3, 13, and 15 mm height. There was no significant association between lateral wall thickness and gender (p > 0.05). However, there was a significant association between lateral wall thickness at 3 and 13 mm and age (p < 0.05). There were significant associations between PBL and age (p < 0.001), and PBL and gender (p < 0.05). Conclusions: PBL might have an association with maxillary sinus lateral bone wall thickness. Further studies are needed to confirm this possible relationship.

Risk factors for sinus membrane perforation during lateral window maxillary sinus floor elevation surgery: A retrospective study

“…The lateral wall of maxillary sinus is the area for bone window preparation, and its thickness varies greatly. The normal range is 0.5–2.5 mm 43 . In this study, the average LWT was 1.46 mm.…”

“…The normal range is 0.5-2.5 mm. 43 In this study, the average LWT was 1.46 mm. Researchers hold different opinions over the correlation between the LWT and SMP.…”

Radiographic assessment of maxillary sinus lateral wall and anatomy of posterior superior alveolar artery: A Cone-Beam Computed Tomographic

“…Dental implants are frequently used to reconstruct edentulous areas of the posterior maxilla. Restoring of the posterior edentulous maxilla with dental implants is challenging due to insufficient height and width of the alveolar bone ridge (Talo Yildirim et al, 2019). To overcome these difficulties, two surgical methods utilised for maxillary sinus augmentation are the lateral window approach and the crestal method (Kiakojori et al, 2017).…”

“…During intervention, it is necessary to predict probability of sinus membrane perforations; the thickness of the lateral sinus wall must be assessed. It is also critical to evaluate the anatomy of the maxillary sinus in order to avoid complications, since PSAA is closely related to the anatomy of the MS (Talo Yildirim et al, 2019;Van Cauwenberge et al, 2004). After the emergence of three-dimensional imaging mode, CBCT is deemed as the gold standard to evaluate the MS lateral wall thickness and its vascular anatomy owing to its accuracy, high resolution, and better tissue contrast by eliminating the overlap of surrounding structures (Van Cauwenberge et al, 2004).…”

Comparison of CGRP distributions in the maxillary sinus and trigeminal ganglion between elderly dentulous and edentulous humans

“…8 9 Age, but not sex, is also an important factor that influences sinus membrane thicknesses measured using CBCT analysis, 10 and periodontal bone loss may be related to MS lateral bone wall thickness. 11 Therefore, we investigated in detail the relationship between CBCT analyses and histochemical observations of SM in the human maxilla. Calcitonin gene-related peptide (CGRP) is involved in vasodilation and interacts with the sympathetic nervous system in the periphery.…”
