Open and closed sinus lift

A sinus lift is a complex procedure, the purpose of which is to build up bone tissue in the upper jaw for the subsequent installation of implants. This technique appeared relatively recently, but has already demonstrated excellent results. With its help, dentists are able to restore bone volume in those areas where it is lacking. After complete healing, the artificial teeth are fixed. Doctors at the K+31 clinic use modern techniques and the latest materials in their work to restore your smile.

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:

  • Open sinus lift. They are used if the patient has virtually no bone tissue left (less than 6 mm) and there is no place to fix the implant. Recovery takes a long time due to significant surgery
  • Closed sinus lift or cross lift. It is considered less invasive and is used to minimally increase bone volume. Closed surgery avoids large incisions and reduces recovery time

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.

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.

General information about the procedure

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:

  1. Avoid eating solid foods
  2. Take antibiotics to prevent infections and anti-inflammatory medications to reduce swelling and discomfort
  3. 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:

  1. 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
  2. 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
  3. Elevation of the sinus mucosa. The process requires precision and accuracy and is performed using microtools
  4. Filling the resulting cavity with bone material. It promotes new bone growth and speeds up healing
  5. 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.

Postoperative period

In the first hours after implantation with sinus lift, the patient may experience slight fatigue, a feeling of heaviness when tilting the head, dry lips and tightness of the oral mucosa. Bleeding may occur, which can be reduced by applying cold to the cheek.

After 12 hours, when the anesthesia wears off, the patient feels pain. To relieve it, the doctor prescribes analgesics and anti-inflammatory drugs, such as Ketorol, Nise, Ketanov. They are taken one tablet per day; in case of severe pain, the dose can be increased.

On the third day, swelling appears, more often in women. Ice applied to the cheek several times a day helps reduce it.

An increase in temperature to 37.5 degrees in the first 3-5 days is a normal reaction of the body. In this case, the use of painkillers and anti-inflammatory drugs is recommended.

Important! If you experience prolonged or increasing pain, frequent bleeding, high fever for more than 3-5 days, or pain when swallowing, you should consult your doctor.

The healing period depends on the extent of the operation. After the open method, the acute phase of healing passes in 3 days, swelling decreases in 2 weeks, after which the gums heal completely.

Healing after closed surgery may take longer. The sutures are removed after 2 weeks, after which the gums are restored in 2-3 days. Bone tissue is formed within 3-6 months.

Physiotherapy after surgery

For a speedy recovery after sinus surgery, doctors prescribe physiotherapeutic procedures. Microcurrent therapy is considered the most effective. Its essence lies in the impact of weak electrical discharges in order to relieve pain, stimulate tissue renewal, reduce swelling and get rid of bruises.

Procedures such as bioreparation and plasma therapy have also proven themselves well. Bioreparation involves the introduction of special drugs that activate blood flow and lymphatic drainage. Doctors also use vitamins and minerals for faster recovery. Plasma therapy involves injections of the patient’s own enriched plasma, which promotes tissue healing and eliminates bruising and swelling.

In addition to these methods, it is recommended to limit physical activity, avoid hot and spicy foods, and solid foods. It is also necessary to avoid sudden breathing movements. Rinsing your mouth is allowed only 24-48 hours after surgery.

Risks and complications of sinus lift

The most common complications include:

  • Infections
  • Implant failure
  • Violation of the integrity of the sinus membrane
  • Prolonged healing
  • Intense bleeding

The likelihood of undesirable consequences is reduced by strictly following the surgeon's recommendations. In rare cases, patients experience sinusitis after surgery. This is due to damage to the Schneiderian membrane by an incompetent surgeon. Sinusitis requires immediate treatment with antibiotics. If it was identified before surgery, the operation is postponed until complete recovery.
