Portions of your sinuses lie behind your cheeks and above your upper teeth. Often your sinus membrane may need to be lifted to make room for a dental implant in that area.
Before the advancement of sinus augmentation, dental implants in sinus affected areas were not possible, leaving patients with dentures as their only option. With modern techniques the membrane can be lifted through a small opening cut into the jawbone. If sufficient bone exists to support the implant, the sinus augmentation can simply be done at the time the implant is installed.
When there’s not enough bone to accommodate an implant, the sinus lift will be performed first, along with a bone grafting to build-up your foundation. Having enough bone architecture is crucial to your implant’s success. With a bone graft, you will need several months to heal before the implant can be added.
