Vertical ridge augmentation combined with maxillary sinus floor elevation in the posterior maxilla: a case series

Abstract

This study aimed to evaluate the clinical and radiographic outcomes of a combined surgical approach involving vertical ridge augmentation (VRA) and lateral window maxillary sinus floor elevation (MSFE) for implant placement. Three patients were treated using different bone materials: one with an allograft, one with a xenograft, and one with a composite of both. The timing of implant placement was dependent on the required amount of vertical bone augmentation: when the implant was ≤3 mm, simultaneous placement was performed, and when the implant was >3 mm, a staged approach was employed. Bone augmentation and prosthetic rehabilitation were successful in all cases. Postoperative radiography revealed an increase in the alveolar ridge height following bone grafting. These findings indicate that the combination of VRA and MSFE yields predictable clinical outcomes and may be a reliable treatment option for patients with severe posterior maxillary atrophy, achieving high implant survival rates following sinus augmentation.
