Can a cotton roll make sinus lifts safer?
NCT ID NCT07794293
First seen Aug 31, 2026 · Last updated Sep 09, 2026 · Updated 3 times
Summary
This trial compares three surgical methods for lifting the sinus floor to make room for dental implants in people with upper jaw bone loss. Researchers will measure bleeding, visibility, simplicity, operation time, and the risk of tearing the sinus membrane. They will also look at how factors like smoking, bone height, and sinus anatomy affect the risk of membrane perforation. The goal is to find which approach offers the best conditions and lowest complication risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Three surgical techniques for lateral sinus floor elevation: standard rotary, epinephrine-soaked cotton roll-assisted, and piezoelectric.
- What this could lead to
- If it works, this could identify the safest and most efficient sinus lift technique, reducing complications and improving outcomes for people needing dental implants.
- What could go wrong
- This is a comparative study, not a test of a new drug, so it may not change practice if results are inconclusive. Surgical risks like membrane perforation and bleeding still apply.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Must be older than 18 years * Clinical diagnosis of absence of one or more maxillary posterior molars with a healing period of at least 6 months after extraction * Clinical indication for Lateral Sinus Floor Elevation with either simultaneous or delayed implant placement; residual bone height ≤5 mm at the planned implant site * Must be confirmed by cone-beam computed tomography (CBCT) * Must have an availability of complete medical, clinical, and radiographic records. Exclusion Criteria: * Pathological sinus mucosal thickening or other radiographic or clinical evidence of sinus disease * Untreated periapical or periodontal infection adjacent to the maxillary sinus * Current or previous exposure to antiresorptive agents (e.g., bisphosphonates or denosumab) or antiangiogenic medication * History of head and neck radiotherapy * Requirement for additional vertical or horizontal bone augmentation procedures other than LSFE * Previous LSFE involving the same maxillary sinus.
