The Relation between Morphology of Maxillary Sinus after Augmentation in Three Classification Methods and Residual Bone Height: A Retrospective Study

Table 5

The RBH values were compared between different morphological classifications based on the biplanes.

Morphology	Mean RBH (mm)	SD (mm)	Max (mm)	Min (mm)	Median (mm)
1	6.47	0.92	8.00	4.50	6.50
2	6.25	1.25	8.00	4.50	6.00
3	5.93	0.68	7.00	5.00	5.75
4	6.50	1.58	9.00	5.00	6.00
5	4.75	0.35	5.00	4.50	4.75
