Table 1 Parameters evaluated on the CBCTs at the various periods

From: Involvement of the maxillary sinus ostium (MSO) in the edematous processes after sinus floor augmentation: a cone-beam computed tomographic study

T0 - Coronal view Distance between the maxillary sinus ostium (MSO) to the X-axis.
Distance between MSO to the floor of the maxillary sinus.
The maxillary infundibulum length, included between the maxillary sinus ostium and the hiatus semilunaris.
The diameter and position of accessory maxillary ostia (ASO).
T0, T1w, T9m - Coronal view The diameter of the MSO.
Patency of the infundibulum evaluated as the number of obstructions.
Virtual mucosa thickness evaluated as the distance between bone/biomaterial and the outer contour of the sinus mucosa.
Virtual area of the sinus mucosa. The limits of the areas measured were defined by the extension of the edema in the 1-week CBCT. In the palatal aspect, the maximum limit of the measurements of the edema was placed at the base of the ostium. In the lateral aspect, this limit was defined by the field of view that cut the image in this region.
T1w, T9m - Coronal view Distance between the vertical extension of the edematous mucosa and the MSO.
T0, T1w, T9m - Lateral view Virtual area of the sinus mucosa. The limits of the areas measured were defined by the extension of the edema in the 1-week CBCT. The maximum limit of the measurements of the edema was the intersection of the superior wall with the mesial and distal sinus walls, respectively.
T1w, T9m - Lateral view The vertical extension of the edematous mucosa at the mesial and distal aspects in relation to Z-axis.
  1. T0 before surgery, T1w after 1 week, T9m after 9 months, MSO maxillary sinus ostium
