Sinus Lift
When you’re considering dental implants in the upper back jaw but have been told there’s insufficient bone to anchor them, a surgical procedure known as a sinus lift, also called sinus augmentation, may be the critical step you need. This forms part of comprehensive implant planning, restoring jawbone structure and enabling long-term implant success.
What is a Sinus Lift?
A sinus lift involves carefully raising the floor of the sinus cavity in the upper jaw, in the region of the molar and premolar teeth, and placing bone graft material beneath the sinus membrane to create a more substantial and stable foundation for dental implants.
Over time, the graft material integrates with your natural bone, allowing safe placement of implants. Without this augmentation, the thin or diminished bone in this area often cannot reliably support the forces of chewing or the long-term survival of the implant.
Why You Might Need a Sinus Lift
​In many cases, when back teeth in the upper jaw have been missing for some time, the underlying bone has resorbed, and the sinus cavity may have expanded downward, leaving inadequate bone height for implant placement. Other causes include advanced gum (periodontal) disease, trauma, or an anatomical variation placing the sinus too close to the jaw. The result is a situation where simply placing an implant would be risky or unstable. The sinus lift restores the bone volume so implants can then be placed safely and securely.
Our Approach at The Dental Suite
At The Dental Suite, we begin all sinus lift treatments with a detailed assessment, including high-resolution imaging (CBCT Scan if needed) and a review of your dental and medical history, to determine if a sinus lift is the right option for you. If we find that bone volume is insufficient for an implant in the upper back region, we will design a tailored treatment plan. This will include the exact type of sinus lift required (for example, a lateral window or internal (osteotome) approach), the graft material best suited for your case, and a timeline for healing and implant placement.
​
During the procedure, performed under local anaesthetic (with IV sedation available if required), our skilled oral surgeons create access to the sinus area, lift the sinus membrane safely, and place the bone graft material. We then monitor your healing over the next few months to ensure the graft integrates fully and that the bone is stable for the dental implant placement.
What to Expect During the Sinus Lift Procedure
When you attend for your consultation, our team will review your scans and explain whether a sinus lift is necessary and how it fits into your wider implant treatment. On the day of surgery, the area will be numbed; the gum flap will be raised, and access to the sinus created. The sinus membrane is gently lifted, and bone grafting material is placed beneath.
Once closed, you’ll be given aftercare instructions and scheduled for follow-ups to assess healing. Healing times vary according to the extent of the graft: modest lifts may allow implant placement soon afterwards, whereas more extensive grafts may require a 4–9 month healing period before implants are fitted.
Benefits of Sinus Lift Surgery
By restoring bone volume in the upper back jaw, a sinus lift opens up the possibility of implant treatment where previously there was insufficient bone. It improves implant stability and longevity, supports better chewing function, and helps maintain the shape of your facial structure by preventing further bone loss. This leads to a restored smile, improved confidence, and a reliable foundation for future dental work.
Suitability & Considerations
Most healthy adults who require dental implants in the upper molar or premolar area will be candidates for a sinus lift, provided they have no medical issues (which we will review at your initial consultation). Non-smokers and those who maintain good oral hygiene generally enjoy the best outcomes. During your planning, we’ll guide you through any risk factors, such as smoking or chronic sinus conditions, to ensure the best possible result.​
Aftercare & Recovery
After the procedure, you can expect some swelling or bruising around the cheek for a few days and possibly a sense of sinus blockage. It’s important to avoid nose-blowing, heavy sneezing or vigorous activities for a while, as these can disrupt the graft and healing process. Pain relief and antibiotics will be prescribed, and follow-up visits will track your progress. With good care, most patients return to normal function within a week or two.​
