Maxillary sinus floor augmentation is a surgical procedure which aims to increase the amount of bone in the posterior maxilla, in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane and placing a bone graft. When a tooth is lost the alveolar process begins to remodel.
When is the sinus lift needed?
After losing teeth in the upper jaw, sinus floor gradually become lower in posterior region (premolars and molars area). When this incident occurs, it is not possible to place implants to replace missing teeth in those areas. Sinus lift will be done to increase bone height by elevating sinus floor and bone grafting to fill in the space.
A sinus lift is done when there is not enough bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed. There are several reasons for this:
Many people who have lost teeth in their upper jaw — particularly the back teeth, or molars — do not have enough bone for implants to be placed. Because of the anatomy of the skull, the back of the upper jaw has less bone than the lower jaw.
Bone may have been lost because of periodontal (gum) disease.
Tooth loss may have led to a loss of bone as well. Once teeth are gone, bone begins to be resorbed (absorbed back into the body). If teeth have been missing for a long time, there often is not enough bone left to place implants.

The maxillary sinus may be too close to the upper jaw for implants to be placed. The shape and the size of this sinus varies from person to person. The sinus also can get larger as you age.
Sinus lifts have become common during the last 15 years as more people get dental implants to replace missing teeth.
Preparation
The bone used in a sinus lift may come from your own body (autogenous bone), from a cadaver (allogeneic bone) or from cow bone (xenograft).
Type of Maxillary sinus lift
Osteotome technique : This technique elevate sinus through crestal ridge. It can be done with implant surgery. It can only be done when there is a minimum of 5 millimeters bone from crestal ridge to sinus floor.
Lateral window technique: This technique elevate sinus floor from lateral bone. It is done when the bone from crestal bone to sinus floor is less than 5 millimeters. Implant can be placed 6-9 months after surgery.
Why would you need a sinus lift?
A sinus lift is a surgical procedure which is performed in order to increase the amount of bone in the upper jaw and may be required before getting dental implants on the upper jaw. … Placing an implant with little bone support increases the risk of implant failure, but can also cause a perforation of the sinus membrane
Can a sinus lift and implant be done at the same time?
A sinus lift is usually done by a specialist. This could be either an oral and maxillofacial surgeon or a periodontist. A sinus lift is done when there is not enough bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed.
When To Call a Professional
After a sinus lift, contact your surgeon if:
Any swelling or pain gets worse over time. (It should decrease after the first two days or so.)
The bleeding does not stop after one to two days.
Bleeding is bright red and continuous. (Normal bleeding after this procedure oozes slowly and is dark red with possible clots.)
You think the bony material may have been dislodged after sneezing or blowing your nose.
A:Although having a tooth pulled is usually very safe, the procedure can allow harmful bacteria into the bloodstream. Gum tissue is also at risk of infection. If you have a condition that puts you at high risk for developing a severe infection, you may need to take antibiotics before and after the extraction.
A:Rest and Recovery. Rest for at least two days after oral surgery. Physical activity is not recommended for 2 to 3 days after your surgery. Typically, you should be able to resume normal daily activities within 48 hours after surgery.
A:Elevate the head for three days. After a surgery to remove wisdom teeth, keep the head and upper body elevated at a 45-degree angle for three days. This way, the blood vessel tone and blood volume near the tooth extraction flows downward instead of pooling in the surgical area
A: Such like other dental surgery treatment. Doctor will premedication with pain-killer and antibiotics to reduce and also anesthesia. Patient might feel a bit uncomfortable after bone graft for 1-2 days
A:The bone graft dental procedure takes between 45-90 minutes and is performed in your dentist’s clinic. The initial recovery period lasts about two weeks. Following the bone graft procedure, the waiting time until a solid bone mass is received is between 3-6 months, in most clinical cases.
Patients who are well prepared for their surgery usually end up having a smoother recovery. We advise our patients to plan ahead and by some soft food items prior to surgery.
Soft foods may be recommended by your oral surgeon after these procedures : Dental Implants , Bone Grafting for Implants, Ridge Augmentation, Sinus Lift, Wisdom Teeth, Teeth-in-an-Hour, Impacted Canines, Orthognathic (Jaw) Surgery
The following are some examples of soft food items to be consumed following surgery such as Wisdom Teeth Removal or Dental Implant Placement, for example:
Hearty soups ( cream of asparagus, lentil, minestrone, split pea )
Juices ( cranberry, apple, grape ), avoid citrus juices for a few days
