The treatment is carried out using modern equipment and advanced materials, ensuring high precision, minimal risk, and excellent aesthetic outcomes.

What is a sinus lift?

A sinus lift is a surgical procedure used to augment bone tissue in the upper jaw, most often in the region of the molars and premolars. It prepares the jaw for implant placement when the existing bone volume or height is insufficient to ensure stable fixation. The procedure involves the use of grafting material that stimulates the growth of new bone.

Causes of bone tissue atrophy

A sinus lift is indicated in cases of advanced bone loss in the maxilla when implantation is required in areas with reduced bone thickness. In such conditions, it is impossible to place a stable implant without first rebuilding the sinus bone.

Normally, the thickness of the upper jaw bone for implant installation should be at least 10 mm. A height below 7 mm is considered insufficient, and a sinus lift is recommended to increase it. If the bone height is less than 4 mm, osteoplasty becomes essential for successful implantation.

Bone atrophy may develop due to:

• Long-term absence of teeth in the upper jaw without prosthetic replacement;
• Age-related changes;
• Periodontal inflammatory diseases;
• Jaw trauma;
• Individual anatomical features;
• Previous surgeries or failed dental procedures.

Atrophy occurs due to the lack of chewing load in areas of missing teeth. Without pressure, the bone tissue gradually resorbs, decreasing in volume. A common result is the descent of the sinus floor, reducing bone height in the alveolar ridge. Additionally, changes in the mucous membrane of the maxillary sinus can further complicate implant placement.

Contraindications to Sinus-Lift Surgery

There are both absolute and temporary contraindications, in which case the procedure is postponed or avoided. The primary goal is to ensure patient safety and a predictable outcome of treatment.

Situations in which the sinus-lift procedure should be postponed:

• Acute inflammatory processes in the oral cavity;
• Chronic sinusitis or other diseases of the maxillary sinuses;
• Advanced osteoporosis;
• Uncontrolled diabetes;
• Active phase of oncological diseases;
• Blood disorders affecting clotting;
• Pregnancy;
• Severe immune deficiency;
• Psychoneurological conditions that interfere with surgical treatment.

If contraindications are present, the dental clinic specialist will prescribe alternative methods to restore lost bone or make an appointment for the procedure after the patient’s condition has stabilized.

Types of Sinus Lift

A sinus lift is a surgical procedure performed to increase bone volume in the upper jaw, specifically in the area of the sinus cavity, when there is not enough bone height to install an implant. Depending on the patient’s anatomy and the level of bone loss, the dentist or surgeon will choose between two main techniques.

Open Sinus Lift

This technique is used when there is a significant lack of bone — usually less than 4-5 mm of sufficient bone. Key features:

1. During an open sinus lift, the sinus cavity is accessed through a lateral incision in the jawbone, creating a small window.
2. The sinus membrane is carefully “lifted”, and the resulting space is filled with bone material — often synthetic or donor bone.
3. This method is ideal for substantial bone grafting prior to implant placement.
4. Implantation may be done as a separate procedure or simultaneously, depending on the case.
5. The procedure is performed under local anesthesia, though sedation may be used for comfort.

Closed Sinus Lift

Used when the bone height is 6 mm or more, this is a minimally invasive method. Characteristics include:

1. A less traumatic technique, as the access point is created directly through the implant site.
2. The sinus membrane is “lifted” using specialized tools through a small tunnel.
3. Typically combined with immediate implant placement in the same session.
4. Reduced discomfort and swelling, and a shorter healing process.

Both sinus lift methods are considered safe and effective. The final choice depends on individual anatomy, existing sufficient bone volume, and the professional assessment by qualified dentists.

Preparing for a Sinus Lift

Proper preparation is crucial for a successful outcome. Here’s what to expect:

1. Evaluation of the oral cavity. Any gum disease, cavities, or inflammation must be treated before the procedure.
2. Discussion of the procedure. Patients are informed about what to expect, from the incision to the healing process, including advice on avoiding sneeze pressure and other post-op care.

With the guidance of qualified dentists, a sinus lift in the clinic can provide the sufficient amount of bone needed for successful implantation, even in challenging anatomical conditions.

How Is the Procedure Performed?

The sinus lift in the clinic begins with preparing the patient:

1. Local anesthesia is typically used, but in some cases, general anesthesia or sedation may be applied;
2. The oral cavity is treated with antiseptics to ensure sterile conditions.

After preparation, the dentist proceeds based on the selected type of sinus floor elevation.

Stages of a Closed Sinus Lift

With the closed sinus lift, access is achieved through the gum, and a small incision is made directly above the area of the back teeth that requires restoration. The sinus membrane is gently lifted using special instruments, and the resulting space is filled with bone material. This method is minimally invasive and ideal when only minor increase bone volume is needed.

Stages of an Open Sinus Lift

For the open sinus lift, the surgeon creates a larger access window or several incisions to reach the floor of the sinus cavity. This technique is chosen when a significant increase bone volume is necessary due to severe atrophy. After reaching the sinus membrane, it is carefully lifted, and the space is filled with either synthetic, donor, or patient-derived bone material.

After the procedure:

• The bone material is placed;
• A membrane may be added if needed;
• The gum is sutured;
• Post-operative care instructions are provided to ensure proper healing.

Recovery Period

After a sinus lift in the clinic, following your dentist’s recommendations is crucial. The healing process can take several weeks or even several months, depending on the complexity and individual factors.

Key stages:

1. Early Recovery (first 3-7 days): Rest, avoid heavy activity, maintain oral hygiene.
2. Suture Removal: Usually done within 7-14 days, depending on healing.
3. Regular Visits: Important to monitor progress and address any concerns early.
4. Restrictions: Avoid hard foods, hot/cold drinks, and pressure on the operated area.

After several months, when a sufficient amount of bone has formed, the patient is ready to install an implant or undergo other dental treatments.

Possible Complications

While the sinus lift procedure is generally safe, potential risks include:

• Discomfort and swelling;
• Bleeding;
• Inflammation;
• Delayed healing;
• Displacement or rejection of the bone material;
• Damage to the sinus membrane.

These risks can be minimized by following your treatment plan and choosing a qualified dentist or surgeon experienced in sinus floor elevation.

Cost of Sinus Lift

The cost depends on the technique (open sinus lift or closed sinus lift), the amount of bone material, and the clinical situation. A precise quote is given after diagnostics and consultation.
