There are cases where dental implants can not be inserted until the sinus lift surgery is performed.
As it name indicates, the sinus lift surgery is an intervention that aims to raise the membrane of the maxillary sinus in order to add an amount of bone quantity, that is required for the implant insertion, because the implant is inserted into the bone .
The maxillary sinus is a cavity located in the upper jaw, is filled with air and communicates with the nasal cavity and the other sinuses.
The cause leading to sinus lift surgery is represented by dental extractions performed in the past, once a tooth being extracted, the bone holding it starts to be absorbed. Therefore, 3 years from the extraction, bone is reabsorbed in 60%, making impossible the implant insertion without the bone addition, or more precisely the sinus lift surgery.
