A sinus lift is performed to reduce the height (usually by 6-8 mm) of the alveolar process of the upper jaw. In addition, the procedure is prescribed for bone loss after tooth extraction or failure of previous implants. Surgery is relevant for insufficient bone density, as well as for patients with a narrow or atypical shape of the maxillary sinuses.

Open and closed sinus lift
To increase the bone mass of the upper jaw, two main sinus lift methods are used: open and closed. The choice of method depends on how much bone tissue the patient has left, as well as the presence of concomitant dental diseases.
What is the difference between open and closed sinus lifting? Let's take a closer look:
The technique of open and closed sinus lifting is significantly different. In the first case, the doctor makes an incision in the gum and a hole in the side wall of the maxillary sinus, then introduces a large amount of osteoplastic material. The closed method involves the introduction of osteoplastic material directly into the sinus through a small hole, after which the implant can be installed.
