Estimation and Comparison of the Thickness of the Maxillary Antral Floor in Sagittal and Coronal Sections Using CBCT Images - A Retrospective Study

Aim: To estimate and compare the thickness of the maxillary antral floor in sagittal and coronal sections using CBCT images Methodology: The study included 100 retrieved CBCT scans which were analyzed retrospectively using CARESTREAM CBCT software with 50 mm diameter and 37 mm height scan volume. The thickness of the floor of maxillary sinus in the sagittal and coronal sections were analyzed and compared and the scans were analyzed by a single observer. Statistical analysis : ANNOVA and SPSS version 15.0 were applied. Results: There was a positive correlation observed between coronal and sagittal values when the correlation was assessed by using Karl Pearson’s Correlation Coefficient. Conclusion: The significant difference between the thickness of the schneiderian membrane when measured in coronal and sagittal section reflects the need for taking into consideration the measurements of both the sections and obtaining an average of them when placing an implant in the maxillary posterior region to avoid perforation of the sinus membrane.
