Maxillary sinus lift (augmentation) with long implants vs Short implants (5 to 8.5 mm) without sinus augmentation

Complications (at treated sites) · Patients with missing teeth and an atrophic posterior maxilla, with residual bone height between 4 and 9 mm below the maxillary sinus

Maxillary sinus lift (augmentation) with long implants may leads to higher complications (at treated sites) compared with short implants (5 to 8.5 mm) without sinus augmentation (low certainty).

Maxillary sinus lift (augmentation) with long implants vs Short implants (5 to 8.5 mm) without sinus augmentation

Implant failure · Patients with missing teeth and an atrophic posterior maxilla, with residual bone height between 4 and 9 mm below the maxillary sinus

Maxillary sinus lift (augmentation) with long implants showed no clear difference in implant failure compared with short implants (5 to 8.5 mm) without sinus augmentation (moderate certainty).
