Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
CBCTs will be taken for all patients before surgery (T0), after 1 week from sinus floor augmentation (T1) and after 9 months of healing (T2) and evaluation of dimensional variations over time of soft and hard tissues will be performed.

test site
The space obtained underneath the sinus mucosa will be filled with the xenograft without protecting the antrostomy with a collagen membrane in the test sites. Bone to implant contact was measured at the turned and machined surface.
Maxillary sinus augmentation
Surgical technique for increasing the vertical bone height of the posterior maxilla an antrostomy of about 5 mm in height and 10 mm long will be prepared using a diamond insert mounted on a sonic-air surgical instrument. The Schneiderian membrane will be elevated and clinical measurements will be performed using an UNC 15 probe. The space obtained underneath the sinus mucosa will be filled with the xenograft and a resorbable collagen membrane will be placed to cover the antrostomy only at the randomly selected control sites.
control site
