It is a common situation, when studying the medical data of the patient, our specialists make the following conclusion: maxillary sinus floor augmentation (sinus lifting) must be performed before implantation. Such a conclusion is stipulated by a very small bone — 4 mm or less. One should not place implants on such a bone, since there is a big risk of the dental implant failure.
There are no such technologies in the today’s world that would allow implants to be placed on an extremely small bones. That is why, sinus lifting should be considered as the only opportunity not to risk their health. If a dentist takes a risk and does not build up, this can lead to aggravation effects within 3-9 months already: failure of implants to the maxillary sinus with its subsequent inflammation, the development of purulent processes; complete implant failure. In the most severe cases, the maxillofacial surgeons will have to come to the aid.
The maxillary sinus floor augmentation can also be assigned to patients with porous structure of the maxillary bone in order to strengthen it.
How is the sinus lifting performed?
Unfortunately, many patients have poor understanding of sinus lifting and paint the operation in black colours. In fact, the augmentation does not differ from any other dental surgery significantly.
The upper jaw in the area of the maxillary sinuses is subjected to interference, since the structure of bone tissue in this part is most prone to atrophy. Bone atrophy develops in case of constant lack of the necessary occlusal loading, for example, after tooth extraction.
It is important to know that a thin bone is not the result of a long-term adentia, but it can also develop three months after the tooth loss. Atrophy can also be associated with the individual features of the structure of the patient’s jaw.
The surgery is performed under local anesthesia, so the patient does not feel any pain. The surgery itself and the postoperative period last without difficulties and great discomfort.
The sinus lifting is a one-day surgery. The duration of the procedure, depending on the specific case, is from one to three hours. Patients from other towns may stay in Minsk for no more than two days (one staying overnight) and have their stitches taken out 7-10 days after the operation at their place of residence.
In our clinic, bone augmentation is performed in two ways: by “open” and “closed” (with simultaneous implant placement) methods using certified materials.
A surgery with an open sinus-lifting is depicted in the diagram below:

Preparation for surgery
Before the maxillary sinus floor augmentation, a patient needs to undergo a medical examination similar to that required for the dental implantation. It is necessary to exclude diseases where this procedure can be contraindicated: slow blood clotting, immune system and cardiovascular disease, maxillary sinus infection, oncology.
The series of tests includes:
- Complete blood count (hematology panel with differential blood count);
- Blood glucose test and coagulation analysis;
- Hepatitis B and C blood tests;
- Local anesthetic (ultracaine, ubestesin, scandonest) and metal (titanium, cobalt, chromium, nickel) allergy testing — only if you have had allergic reactions in the past;
- Serological screening tests for HIV/AIDS and syphilis;
- Blood chemistry – AST, ALT, urea, creatinine, bilirubin, calcium, sodium, phosphorus;
- Thyroid ultrasound of the gland (in case of thyroid dysfunction, the endocrinologist’s conclusion must be submitted);
- The family doctor’s conclusion on the absence of contraindications to implantation.
Recovery period after the sinus lifting procedure
After the sinus lifting it will take a patient a month to recover. During this period, the patient must take the medications prescribed by the surgeon, and practice proper oral hygiene. You should also keep a diet, eating no hard, cold and hot food.
In addition, it is recommended to perform no heavy physical work; play no sports; lift no weights; not to travel by air frequently. It is absolutely forbidden to drink alcohol.
Patients should keep in mind that a strong cough and sneezing during the recovery period can lead to a significant displacement of bone tissue, so they should exercise caution.
If patients carefully follow these simple rules, the probability of postoperative complications is minimized. Three months after the operation, a comparison X-ray should be made. If the filled bone material has taken well and become part of the bone tissue, you are ready for implantation.

An example of the sinus lifting performed in Dentistry
A patient came to our clinic with the following problem: there is adentia with bone atrophy in the right upper jaw, a tooth is missing in the left part. In addition, there is a large cyst in the left part of the jaw (it is highlighted in red).
Since 2002, there are porcelain-fused-to-metal dental bridges in the lateral parts of the lower jaw. At the time of the patient’s treatment, bridges were unstable, there are lodged food and debris.
A cyst was removed, its former location was filled with artificial bone material; sinus lifting was performed in the left part of the maxilla.
Four months later, classic ROOTT implants placed into the maxillary sinus floor augmentation side (including, side of the former cyst).
Implants on the lower jaw were also placed at this stage. A prosthetic appliance by temporary structures for the implants was made in order to achieve rapid bone integration.
Six months after the implantation, the patient underwent a final stage of treatment – prosthetics with porcelain-fused-to-metal dental crowns on implants. A part of the patient’s natural teeth was also restored using porcelain-fused-to-metal dental crowns.
During the whole treatment period, the patient followed the doctors’ recommendations and had comparison X-ray in time. As a result, the bone material and implants had a reliably integration at the augmentation side. The construction take came up to 100%.
