At a glance
- The maxillary sinuses are air-filled cavities located above the back teeth of the upper jaw.
- A lateral window sinus lift involves creating a small opening in the side wall of the sinus to place graft material directly, and is typically used when significant bone height is needed.
- After a sinus lift, mild swelling, nasal congestion, or minor bleeding from the nose can occur and typically resolves within a week to ten days.
- Sinus lift procedures have a long, well-documented track record and are considered a predictable, routine part of implant dentistry when performed by an experienced surgeon with appropriate imaging and planning beforehand.
Why the Sinus Matters for Upper Jaw Implants
The maxillary sinuses are air-filled cavities located above the back teeth of the upper jaw. When teeth are lost in this area, or when the sinus naturally expands with age, the amount of bone available below the sinus floor can become too thin to support a dental implant safely.
A sinus lift, also called sinus augmentation, gently raises the sinus membrane and places bone grafting material in the space created, effectively increasing the bone height available for implant placement in the upper back jaw.
Types of Sinus Lift Procedures
A lateral window sinus lift involves creating a small opening in the side wall of the sinus to place graft material directly, and is typically used when significant bone height is needed. This approach usually requires a healing period before implants can be placed.
A crestal or internal sinus lift is a less invasive technique performed through the same site where the implant will be placed, gently lifting the sinus floor from below. This is generally reserved for cases needing only a modest increase in bone height and can sometimes allow the implant to be placed in the same visit.
Safety and Success Rates
Sinus lift procedures have a long, well-documented track record and are considered a predictable, routine part of implant dentistry when performed by an experienced surgeon with appropriate imaging and planning beforehand.
As with any surgical procedure, there are some risks, including sinus membrane perforation, which is usually managed successfully during surgery without affecting the overall outcome. Choosing a surgeon experienced in this specific technique helps minimise complications.
What Happens During Recovery
After a sinus lift, mild swelling, nasal congestion, or minor bleeding from the nose can occur and typically resolves within a week to ten days. Patients are usually advised to avoid blowing their nose forcefully, flying, or strenuous exercise for a period to prevent pressure changes affecting the healing graft.
Healing time before implant placement depends on the amount of grafting performed, ranging from a few months for minor lifts combined with simultaneous implant placement, to six months or longer when a larger lateral window graft is required.
Questions patients ask us
- Will a sinus lift affect my breathing?
- No, a sinus lift does not affect normal breathing. Some patients experience temporary nasal congestion or mild discomfort near the sinus area during healing, but this settles within one to two weeks and does not cause any lasting respiratory issues.
- Can implants be placed at the same time as a sinus lift?
- In cases where there is still a reasonable amount of existing bone, implants can sometimes be placed at the same time as the sinus lift. Where bone height is very limited, the graft is usually allowed to heal first before implants are placed.
- Is a sinus lift always needed for upper back teeth implants?
- Not always. It depends entirely on the amount of natural bone height below your sinus, which is assessed accurately through a CBCT scan. Many patients have sufficient bone and do not require this additional procedure at all.
- How successful are implants placed after a sinus lift?
- Implants placed following a well-healed sinus lift have success rates comparable to implants placed in naturally sufficient bone, provided the patient follows post-operative care instructions and maintains good long-term oral hygiene.
