Sinus Lift Procedure (Sinus Elevation)
A sinus lift is a surgical procedure that elevates the sinus floor membrane and grafts bone material into the upper posterior jaw to create sufficient bone height for dental implants.
Key Advantages & Features
- Enables implant placement in deficient upper posterior jawbone
- Safe, delicate surgical procedure preserving sinus membrane integrity
- Provides primary stability for titanium dental implants
- Performed under painless local anesthesia or sedation
Clinical Indications
- Vertical bone height under 5-6 mm in the upper molar region
- Sinus pneumatization following long-term tooth loss
- Pre-implant bone augmentation requirements
Detailed Medical Overview
Following upper molar extractions, the bone in the back jaw naturally resorbs, and the maxillary sinus expands downward. This reduces available vertical bone height required for secure implant placement.
During a sinus lift, the oral surgeon gently elevates the Schneiderian sinus membrane and inserts biocompatible bone graft material into the created space.
Performed via Lateral Window or Internal Osteotome techniques depending on bone deficit, it enables successful long-term implant integration in otherwise challenging cases.
