However, respective clinical long\u2010term data are scarce.

In one hundred twenty\u2010seven sites, bone augmentation procedures were performed. Hereof, 96 sites were sinus augmentation procedures and 31 sites were alveolar ridge augmentations. For patients with sinus augmentation procedures, implant survival was 97.9% and for patients with alveolar ridge augmentations, implant survival was 93.5% after 5 years, indicating a higher implant survival for sinus augmentation, however not statistically different (<jats:italic>p<\/jats:italic>\u2009=\u2009.194).
