Two types are distinguished: the closed or open sinus lift. There is no reason to worry because the local anesthesia makes the intervention painless.
Closed sinus lift or crestal sinus lift
This type of sinus lift is recommended in case of less bone loss. Through the site of the planned implant, bone grafting material is inserted into the sinus cavity and its passages. The bone grafting material is incorporated into a bone-like hard material over time, and it is embedded into. So it can be safely implanted.
Opened sinus lift or lateral sinus lift
This procedure is performed in case of a larger amount of bone-missing. It is a bit more complicated than the closed sinus lift, as the bone grafting area is also bigger. Our dental surgeons open the sinus through the gums. Place the bone grafting material there until it reaches the desired height. It is covered with a special membrane, which also helps the healing.
