Why a Sinus Lift May Be Needed
In the back of the upper jaw, the maxillary sinus can sit close to where implant roots would need to go, and the amount of bone in this area often reduces further once a tooth has been missing for some time. A sinus lift addresses this specific anatomical situation by creating more room for an implant to be placed securely.
What a Sinus Lift Generally Involves
The lining of the sinus is carefully lifted, and grafting material is placed in the space created beneath it to increase the available bone. Depending on the case, an implant may be placed at the same time as the sinus lift, or at a later stage once the graft has had time to integrate — this is a planning decision made after assessment.
Sinus Lift Compared with General Bone Grafting
A sinus lift is specific to the back of the upper jaw, addressing the particular anatomical relationship with the sinus. Bone grafting more generally can apply at other sites in the jaw, for different reasons. See Bone Grafting for that broader procedure.
Where a Sinus Lift May Be Relevant
A sinus lift is relevant only to implants being placed in the upper back jaw, which can come up in the context of a single tooth implant, multiple implants, or full-arch approaches such as All-on-4 or All-on-6, depending on which teeth are involved. Whichever treatment you're considering, your own assessment and imaging would establish whether a sinus lift applies.
Assessment Considerations
Imaging is used to assess the position of the sinus and the amount of bone beneath it at the relevant site, which determines whether a sinus lift is relevant and how it would be planned alongside any implant placement.
What to Expect in General Terms
As with bone grafting generally, a sinus lift needs a period of healing and integration before it can reliably support an implant. Exact timing depends on the individual case and isn't stated in general terms here.
Considerations and Limitations
A sinus lift involves working close to the sinus, and general considerations specific to this area would be discussed with you individually as part of assessment. Outcomes and healing vary between individuals.
Aftercare
General aftercare for a sinus lift typically involves guidance specific to the upper jaw and sinus area, alongside standard advice on keeping the area clean while it heals. Your dental team would talk you through what to expect for your own case before you leave.
