Sinus lifting, also known as sinus augmentation or sinus elevation, is a surgical procedure that aims to increase the bone volume in the upper jaw's posterior region (molar area) to facilitate the placement of dental implants. This procedure involves elevating the sinus membrane and adding a bone graft to create sufficient bone height for implant placement.

Why is Sinus Lifting Performed?

• Insufficient Bone Volume: The bone volume in the upper jaw's posterior region is often thin, making it difficult to place dental implants.
• Expansion of Sinus Cavities: With age or after tooth loss, sinus cavities can expand, reducing the amount of available bone.
• Dental Implant Placement: Sinus lifting is performed to ensure sufficient bone volume for the successful placement of dental implants.

How is Sinus Lifting Performed?

1. Evaluation and Planning

• Radiographic Examination: The dentist uses panoramic X-rays or 3D cone beam computed tomography (CBCT) scans to evaluate the condition of the sinuses and bone structure.
• Examination and Medical History: Your overall health and suitability for sinus lifting are assessed.

2. Surgical Procedure

• Anesthesia: The procedure is typically done under local anesthesia, but sedation or general anesthesia may be used in some cases.
• Sinus Elevation: An incision is made in the gum to expose the bone surface. A small window is created in the bone, and the sinus membrane is carefully lifted.
• Bone Graft Placement: The bone graft is placed beneath the elevated sinus membrane. The graft can be synthetic materials, autograft (patient's own bone), or xenograft (animal-derived bone).
• Closure: The window is closed, and the gum is sutured.

3. Healing Process

• Osteointegration: The graft material integrates with the existing bone over a period of 4-9 months, increasing the bone volume and making it suitable for implant placement.
• Follow-Up: Regular check-ups are scheduled to monitor the healing process.

Post-Operative Care and Recovery

• Pain Management: Pain relievers and, if necessary, antibiotics are prescribed.
• Swelling and Bruising: Apply a cold compress for the first 24 hours.
• Diet: Consume soft and cold foods, avoiding hot and hard foods.
• Oral Hygiene: Do not rinse your mouth during the first 24 hours; thereafter, gently brush and rinse with saline solution.
• Rest and Activity: Limit physical activities and ensure adequate rest.
• Avoid Strain: Avoid activities that increase sinus pressure, such as blowing your nose, sneezing, and heavy lifting for the first few weeks.

Sinus lifting is an effective and safe procedure to provide adequate bone volume for dental implant placement. Successful outcomes depend on accurate diagnosis and careful execution of the procedure.
