Strategies Using Maxillary Sinus Buccal Bony Window for Sinus Floor Elevation in Patients with Low Residual Bone Height

What this Trial Is About

The trial investigates different surgical methods for maxillary sinus floor elevation in participants who have varying residual bone heights of 0 to 5 millimeters. Researchers aim to identify the best operating technique by comparing approaches using the maxillary sinus buccal bony window. This research involves adults aged 18 to 80 years who need sinus floor augmentation and seeks to assist surgeons in selecting optimal procedures for patients with differing bone conditions. Participants are assigned randomly to one of six groups based on their residual bone height and the surgical method used. The methods include grinding the bone into pieces, replacing the bone, or turning the bone inward to support the membrane. These approaches are applied during lateral maxillary sinus floor elevation surgery. The study enrolls 60 participants divided by bone height categories 0 to 3 mm and 3 to 5 mm. Throughout the study, researchers collect participant information and analyze Cone Beam Computed Tomography CBCT data. They measure outcomes such as changes in alveolar bone height and the extent of new bone growth at multiple time points before surgery, and 6 months, 1, 2, 3, 5, and 10 years after surgery. The study also monitors residual bone height at baseline. This comprehensive follow-up evaluates which surgical strategy performs best over the long term.
