Study Comparing Bone Growth With and Without Sinus Floor Perforation During Sinus Floor Elevation for Dental Implants

What this Trial Is About

This research aims to compare new bone growth after sinus floor elevation surgery in patients needing dental implants. The study focuses on whether making multiple small holes perforations in the cortical bone layer of the sinus floor before placing augmenting material improves bone formation. The trial involves 12 patients who require sinus floor elevation on both sides of the mouth, allowing direct comparison within each patient. Participants will undergo a lateral window sinus floor elevation on both sides. One side will follow the standard procedure by filling the sinus with augmentation material without perforation. The other side will have several perforations made in the cortical bone layer before the augmentation material is inserted to enhance blood supply to the graft. Both sides will then heal for 4 to 6 months before dental implants are placed. During implant placement, a bone biopsy will be taken from the treated areas to assess new bone formation through histological analysis. The study includes randomized assignment of sides and double-blinding to ensure unbiased results. Participants will be monitored throughout the healing period, with the main outcome measured at 4 to 6 months after surgery to compare bone growth between the two procedures.
