The Sinus lift may be necessary for patients who need dental implants and not enough bone material. This occurs when the upper jawbones are not thick enough or the sinuses are too close to accommodate dental implants.

This may be due to periodontal disease or lack of teeth. During a sinus lift, the surgeon lifts the maxillary sinus membrane and inserts a artificial bone or bio-bone to fill the space. If enough bone is present, a dental implant can be inserted immediately, otherwise it will be necessary to wait for the bone to heal before inserting the implant.
