Biomechanical Analysis of Grafted and Nongrafted Maxillary Sinus Augmentation in the Atrophic Posterior Maxilla with Three-Dimensional Finite Element Method

Figure 1

Simplified maxillary segment model. The buccolingual and mesiodistal distance was 10 mm; the overall height was 14 mm. The maxillary models were classified into 4 groups by RBH: 3 mm, 5 mm, 7 mm, and 10 mm.
