Comparing two techniques for lifting the maxillary sinus floor during dental implant placement
Official title: Osseodensification Versus Osteotome Internal Sinus Lifting in Delayed Implant Placement (A Randomized Controlled Clinical Trial)
Run by Ain Shams University · NCT05495490 · Data updated 2026-11-12
This study is testing two different methods for lifting the maxillary sinus during dental implant surgery to see which one works better for patients with missing teeth in the upper jaw.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 40 with a partially edentulous maxillary posterior ridge and a residual alveolar ridge height of 4 to 6 mm.
✕Probably not a fit
Patients with smoking habits, uncontrolled systemic diseases, or those with acute or chronic sinus issues may not benefit from this study.

What this trial studies
This clinical trial aims to compare the efficacy of two techniques for maxillary sinus floor augmentation: Osseodensification and Osteotome internal sinus lifting. Twenty patients with a maxillary posterior edentulous ridge will be randomly assigned to either technique, utilizing sticky bone as graft material. Pre-surgical evaluations will include Cone Beam Computed Tomography (CBCT) to assess sinus anatomy and residual ridge dimensions. Post-surgery, the study will evaluate bone gain, bone density, and implant stability, alongside patient-reported outcomes regarding pain and recovery.
Why it matters
Potential benefit: If successful, this study could improve dental implant outcomes and patient comfort during sinus lift procedures.
How similar studies have gone: While similar techniques have been explored, this specific comparison of Osseodensification and Osteotome internal sinus lifting is relatively novel.
