General Information about sinus lifting
Called "sinus enhancement", it is recommended when the height of the jaw bone is not sufficient to be able to place implants. This is the elevation of the sinus floor and like any surgery it can be frightening but it is a relatively common procedure. During the consultation and following a panoramic radiography of the teeth, the dental surgeon studies the maxillary bone structure of the patient. A minimum height of 8 mm is required to be able to place an implant.
The maxillary sinus is an air-filled cavity in the maxilla where the roots of the upper premolars and molars are present. It is possible that after tooth extraction or loss, the bone naturally resorbs and eventually atrophies. In this case, the dentist will suggest raising the sinus floor and filling it with a bone graft in order to find the correct height of the bone to be able to place implants.
There are two types of sinus lift:
Internal Sinus Lift (open sinus filling)
If there is just the right space, the sinus membrane will be lifted with a suitable tool and with a slight sinus filling, the implant will be placed at the same sessions. For example, if we have a bone height of 6 to 7 mm, filling the sinus from 2 to 3 mm, we can place an implant. And in 3 months, we can move on to the prosthesis stage. It takes 5 days for metal-ceramic crowns and 6 days for zirconium crowns. However, the fitting of all on 4 prostheses can last from 7 to 12 days.
External Sinus Lift (closed sinus filling)
If you have a bone height of less than 5 mm, surgeon has to open a window on the sinus wall, with a suitable tool the sinus will be filled and the space gained will be filled by a bone graft. If your dentist thinks of ensuring stability, he can place the implant during the same session, otherwise he decides to wait for calcification.
After the operation, you have to wait for the soft tissue to heal. Mild disorders may appear such as edema of the cheek, slight bleeding from the mouth or nose and the appearance of a hematoma. It is important to follow the advice of your dentist, who can sometimes prescribe antibiotics and / or analgesics.
