Sinus lifts make dental implants in the upper jaw possible when there is not enough bone.
For a dental implant to succeed there needs to be enough bone to support the implant. In the upper jaw, just above the back teeth, there is an air space called the maxillary sinus. When the upper molars are lost, the bone that was supporting the teeth can shrink, so there is only a thin portion of bone protecting the sinus. If an implant is placed and it perforates the sinus, this can lead to sinus infections.
Luckily we can increase the thickness of the bone protecting the sinus by carrying out a procedure called a sinus lift. This involves making a small hole into the sinus, then “lifting” the lining of the sinus out of the way and adding a bone graft. This allows adequate bone to firmly secure the implant in place without perforating the sinus and risking infections.
BONE GRAFT OPTIONS
There are many different options when it comes to where you can get the bone graft from:
- Autogenous – obtained from your own body
- Allogenic – obtained from a human donor
- Xenogenic – obtained from an animal of a different species (e.g. a cow or pig)
- Alloplastic – synthetic bone graft made in the lab
All of the options are safe and provide good results. The sinus has very good healing potential when it come to bone grafts, so the results are predictable.
The healing time of a sinus lift varies. The gums where the small hole was made into the sinus will heal rapidly (in 2-3 weeks); however, the bone takes longer to heal. Small bone grafts can heal in as little as 3 months where large bone grafts can take as long as 9 months to completely heal.
