The Sinus Lift, also called sinus augmentation surgery, involves inserting bone of animal origin (completely bio-compatible 100%) inside the sinus, in order to insert implants in the areas of the upper molars and premolars, in the absence of natural bone.
WHEN IS IT NECESSARY TO UNDERGO SINUS LIFT SURGERY
In most cases, the bone in the posterior zones of the upper arch is insufficient to insert implants, due to the presence of a cavity called the “maxillary sinus”.
When the bone thickness is less than 5 / 6mm, it is necessary to proceed with the Sinus Lift surgery to allow for the insertion of implants with a minimum length of 10/11 mm.
The dentist proceeds with an incision of the mucosa, then the tissue is detached, a trap door is created in the maxillary sinus and the membrane of the maxillary sinus is detached. The space created is filled with biocompatible bone.
At this point, on the bone that needs to regenerate, our dentists place the biocompatible membrane that acts as a protective barrier and prevents the rapidly growing soft tissue from invading the site, which instead will be gradually occupied by the gradually growing bone
After that, sutures will be applied which will be removed after just 15 days. After about 6 months the implants can be inserted. In some cases the implants can be inserted at the same time as the operation, but it depends on the residual amount of bone: if it is greater than 3-4mm, the implants can be inserted immediately, otherwise they will be inserted later.
In case you need to extract compromised teeth in the sites where Sinus Lift surgery is required, it will be mandatory to wait for the complete healing of the extraction site which takes place in about 3 months.
In cases where sinus membrane perforation occurs during displacement during a Sinus Lift operation, it may be necessary to postpone the operation for another 3 months.
Perforation could occur if the sinus membrane is too thin or if it has undergone inflammatory processes.
HEMATOMA : swelling of the face on the surgery side is almost always present with the formation of a hematoma under the eye
PAIN : it can be present, but if the protocol given to the patient is strictly followed, it can be controlled with normal painkillers.
BLEEDING FROM THE NOSE : in some cases, on the same day of surgery or in the following days, there may be nasal bleeding.
In these cases we recommend that you contact the clinic to make this known.
WHAT TO DO BEFORE SURGERY
It is necessary to take the antibiotic and strictly follow the protocol given to the patient. Our medical staff in this regard will provide all the information. It is necessary to have fasted for at least 4 hours before the surgery and to be accompanied.
