Contraindications for surgery
- Blood clotting disorders. This condition increases the likelihood of bleeding and hematomas
- Progressive diseases. Patients with endocrine or cardiac disorders may face serious complications
- The presence of bad habits. Alcohol, smoking and drugs slow down tissue healing
- Recently undergone chemotherapy or radiation therapy. They weaken the body's ability to regenerate
- Chronic diseases of the nose and paranasal sinuses. Rhinitis, sinusitis, nasal polyps can cause complications during sinus lift
- Pregnancy and lactation. The operation carries risks for the health of mother and child
- Oncology. Any surgical intervention can aggravate the condition
Why do you need a sinus lift?
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.
Operation steps
Before proceeding with sinus lift surgery, the patient undergoes blood and urine tests, as well as testing for HIV and hepatitis. Doctors also prescribe x-rays or computed tomography of the upper jaw, and sometimes the chest. Depending on the state of health, the patient may require consultations with highly specialized specialists - a therapist, a cardiologist, an endocrinologist.
In the preparatory period before sinus lift, the doctor recommends following a number of rules:
- Avoid eating solid foods
- Take antibiotics to prevent infections and anti-inflammatory medications to reduce swelling and discomfort
- Get professional teeth cleaning
If surgery is scheduled for a cardiac patient, he must stop taking blood thinning medications a day before the intervention. The most commonly used are Aspirin, Asparkam, Valsartan.
Sinus lift consists of the following stages:
- Anesthesia. Local anesthesia is usually used. For those patients who have a strong fear of dental procedures, sedation is provided. The anesthesiologist monitors the patient's condition
- Creating access to the maxillary sinus. Depending on the technique, this may be a small hole for an open method or a tunnel for a closed one
- Elevation of the sinus mucosa. The process requires precision and accuracy and is performed using microtools
- Filling the resulting cavity with bone material. It promotes new bone growth and speeds up healing
- Complete operation. Depending on the method, an implant or a barrier membrane is installed. The operation ends with suturing and antiseptic treatment
After a closed sinus lift, bruising and swelling are less pronounced than after an open operation. The rehabilitation period is faster and easier.

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.
