Types of sinus lift
Open sinus lift
The method is indicated for significant reduction of bone tissue in the anterior dental apparatus (less than 5 mm), which makes it impossible to install dental implants. The procedure begins with creating access to the sinus through the side wall. Through a small incision, the surgeon lifts the sinus membrane. The raised bottom of the sinus is filled with bone material, after which the doctor sutures the incision. The price of an open sinus lift is higher than for a closed operation, which is due to the large number of manipulations.
In the postoperative period, the patient must follow the recommendations for dental care, including rinsing with antiseptic solutions and taking antibiotics. It is important to avoid physical activity and smoking for at least 2 weeks. Healing takes 4 to 6 months, during which the bone material integrates with the natural bone.
Closed sinus lift
The technique is used in cases of moderate bone loss (5-7 mm), when it is necessary to add 2-3 mm of bone to install a dental implant. This procedure is performed minimally invasively through the alveolar foramen, without creating a lateral window. The surgeon makes a small puncture in the gum and gently lifts the membrane, increasing the pressure, after which he introduces a small volume of bone material to support the dental implant.
The recovery period after this type of intervention takes less time. The patient is advised to avoid physical activity and smoking for 1-2 weeks, maintain oral hygiene, including regular rinsing with antiseptic solutions. Complete healing takes 3-4 months.
General information about the procedure
Pros and Cons of the Technology
The advantages of the procedure include:
- Bone augmentation. Bone augmentation surgery increases both the height and volume of the bone structure in the anterior jaw area, which is essential for the placement of dental implants.
- Increased stability. Increased bone volume allows for more secure placement of dental implants, reducing the likelihood of them shifting or falling out.
- Increased functionality and appearance. Bone augmentation helps restore full chewing function, while dental implants help maintain the natural contours of the face.
The dentist augments bone mass, ensuring long-term stability and durability of the installed dental implants. Sinus lifting reduces the need for additional surgical interventions and provides a higher probability of successful osseointegration.
Despite many advantages, the technology has a number of disadvantages. Among them:
- Possibility of damage to the dental apparatus
- Possibility of puncture of the maxillary sinus
- Postoperative negative consequences (inflammation, infection)
The disadvantages of the procedure also include the risk of bleeding and swelling in the area of the operation. Rehabilitation includes taking antibacterial drugs, limiting physical activity, avoiding hard foods and regularly rinsing the teeth with antiseptic solutions to prevent infection.
Contraindications to bone grafting
Doctors distinguish 2 groups of contraindications for sinus lifting: general and local. General ones include:
- Serious diseases of internal organs
- Immune disorders
- Diseases of the bone and endocrine systems
- Diseases of the nervous system
- Malignant tumors
- Blood diseases
- Active tuberculosis
- HIV
- Pregnancy
- Smoking
Local contraindications are divided into dental problems (cysts, tumors, periodontitis, bite problems, dental bruxism) and nasal pathologies (inflammation of the sinuses, cysts, obstruction of the nasal passages, benign and malignant tumors). Absolute contraindications include significant sinus deformities, chronic recurrent sinusitis with polyps.

What is sinus lift?
A missing tooth is the reason for insufficient load on the base of the jaw. As a result, bone tissue atrophies and decreases in size. Implantation is an advanced method for restoring missing teeth. For treatment, it is important that the artificial root is stably strengthened in the bone.
In the case of atrophy, the installation of dental implants is impossible, so scientists have developed a technique that helps increase bone tissue and restore its normal density. The principle of sinus lifting is based on the transplantation of osteomaterial into the problem area, resulting in the formation of one's own bone tissue.
