Biological Principles and Physiology of Bone Regeneration under the Schneiderian Membrane after Sinus Lift Surgery: A Radiological Study in 14 Patients Treated with the Transcrestal Hydrodynamic Ultrasonic Cavitational Sinus Lift (Intralift)
Introduction. Sinus lift procedures are a commonly accepted method of bone augmentation in the lateral
maxilla with clinically good results. Nevertheless the role of the Schneiderian membrane in
the bone-reformation process is discussed controversially. Aim of this study was to prove the
key role of the sinus membrane in bone reformation in vivo. Material and Methods. 14 patients were treated with the minimal invasive tHUCSL-Intralift, and 2âccm collagenous
sponges were inserted subantrally and the calcification process followed up with CBCT scans
4 and 7 months after surgery. Results. An even and circular centripetal calcification under the sinus membrane and the antral floor
was detected 4 months after surgery covering 30% of the entire augmentation
width/height/depth at each wall. The calcification process was completed in the entire
augmentation volume after 7 months. A loss of approximately 13% of absolute augmentation
height was detected between the 4th and 7th month. Discussion. The results of this paper prove the key role of the sinus membrane as the main carrier of
bone reformation after sinus lift procedures as multiple experimental studies suggested. Thus
the importance of minimal invasive and rupture free sinuslift procedures is underlined and
does not depend on the type of grafting material used
