Sinus Lifting: Preparing the Upper Jaw for Implants

When planning dental implants in the upper jaw—particularly in the back molar and premolar regions—a common challenge is insufficient bone height due to the proximity of the maxillary sinus. In such cases, a sinus lift (also known as sinus augmentation) becomes essential. This surgical procedure increases the amount of bone available by gently lifting the sinus membrane and placing bone graft material in the space beneath it.

At LHC Clinic, we offer both open and closed sinus lifting techniques using high-quality bone graft materials to ensure optimal implant support and long-term success, especially for patients who have experienced bone loss in the upper jaw.

Why Is Sinus Lifting Necessary?

After tooth loss, the bone in the upper jaw tends to resorb over time, and the sinus cavity may expand downward into the area previously occupied by the roots of the teeth. This reduces the vertical bone height, making it difficult—or even impossible—to place implants without additional support.

• Rebuild lost bone for stable implant placement
• Avoid sinus perforation during surgery
• Ensure long-term implant success and function

Open vs. Closed Sinus Lifting: What's the Difference?

• Open Sinus Lift (Lateral Window Technique):
  • Used when bone height is severely reduced (less than 4–5 mm)
  • A small window is created on the lateral wall of the sinus
  • The sinus membrane is gently elevated, and bone graft material is inserted
  • Healing time: Typically, 6–9 months before implants can be placed
  • Ideal for: Patients with significant bone loss in the upper jaw who need major augmentation
• Closed Sinus Lift (Crestal Approach):
  • Minimally invasive techniques performed from the implant site
  • Used when moderate bone height remains (5–8 mm)
  • The sinus floor is gently pushed upward through the implant hole using special instruments
  • Bone graft is placed through the same channel
  • Ideal for: Patients with moderate bone loss, seeking quicker treatment with less surgical trauma

Bone Graft Materials Used at LHC Clinic

• Autogenous bone (from the patient)
• Allografts and xenografts (biocompatible donor or bovine materials)
• Synthetic bone substitutes when suitable

These materials stimulate new bone growth and integrate with the patient's own bone over time, creating a strong foundation for implants.

The Sinus Lift Procedure at LHC Clinic

• Comprehensive 3D Evaluation: Using CBCT (Cone Beam CT) scans to assess sinus anatomy, bone height, and choose the best approach.
• Tailored Treatment Planning: Deciding between open or closed technique based on the individual case.
• Comfort and Safety: Performed under local anesthesia (with sedation if needed) for a relaxed and pain-free experience.
• Careful Grafting: Our experienced surgeons ensure precise membrane elevation and safe bone placement without sinus damage.
• Follow-Up and Healing: Detailed post-operative care instructions and follow-up visits to ensure smooth healing before implant placement.

Benefits of Sinus Lifting at LHC Clinic

• Enables implant placement in previously impossible areas
• Minimally invasive techniques available
• High-quality, sterile graft materials
• Performed by skilled oral surgeons
• Long-term improvement in oral health and function

Frequently Asked Questions

• Is sinus lifting painful? The procedure is performed under anesthesia, and discomfort is minimal. Some swelling and tenderness are normal for a few days.
• How long do I need to wait after a sinus lift before getting implants? With open sinus lifts, usually 6–9 months. With closed lifts, implants are often placed immediately.
• What are the risks? When performed by experienced surgeons, risks are low. Potential issues like sinus membrane perforation or infection are rare and manageable.

Sinus lifting is a safe, predictable, and essential technique that allows patients with upper jawbone loss to benefit from the life-changing advantages of dental implants. At LHC Clinic, we use cutting-edge technology and expert care to perform both open and closed sinus lifts, tailored to each patient’s anatomical needs and treatment goals.

If you’ve been told you don’t have enough bone for implants in the upper jaw, a sinus lift at LHC Clinic could be the first step toward restoring your full, functional smile.
