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

<div>Two types of maxillary sinus augmentation approaches. (a) Grafted sinus augmentation: the apical portion of the implant was totally embedded into the graft; (b) Nongrafted sinus augmentation.</div>
