Figure illustrating the reference points of the CBCT measurements. A: most posterior point of the sinus wall; B: most anterior point of the sinus wall; C: mid-point between A and B; C1: measurement of mucosal thickening perpendicular to AB line at point C; D: mid-point between A and C; D1: measurement of mucosal thickening perpendicular to AB line at point D; E: mid-point between B and C; E1: measurement of mucosal thickening perpendicular to AB line at point E; F: highest extension of thickened sinus membrane; GH: height of residual alveolar bone (measured at the mid-point of the edentulous ridge/implant-planned site)
