A sinus lift (a sinus augmentation) is surgery that adds bone to the upper jaw in the area of molars and premolars to make it taller. The bone is added between jaw and the maxillary sinuses, which are on either side of the nose. To make room for the bone, the sinus membrane has to be moved upward, or "lifted." A sinus lift usually is done by an oral and maxillofacial surgeon or a periodontist.
It can happen that there is no longer enough bone in the molar area of the maxilla in the direction of the floor of the sinus because of the bone atrophy after tooth loss. As bone augmentation in this region is possible only with difficulty, a method was developed in which the floor of the sinus is raised and bone is inserted into the cavity produced, without injuring the mucosa of the sinus, which leads to an effective increase in the bone in the molar maxillary region. This operation is called a sinus lift. This operation can be carried out under local anaesthesia and is done through the mouth so that there are no scars on the face. The sinus lift operation can often be done at the same time as the insertion of dental implants. The bone material which is inserted corresponds to that described already for bone augmentation. |
