Emphysema after Sinus Grafting: Importance of Patient's Information, Early Diagnosis, and Management.

The sinus elevation procedure is a safe and predictable technique that allows the placement of implants in atrophic posterior maxillae. However, some recommendations have to be followed by the patient to ensure reliable healing. It is particularly important to avoid inducing trauma in the region concerned and through the sinuses.

Paradigm shift in the management of the atrophic posterior maxilla.

When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ≤4 mm.
