Dental treatments have experienced many changes in recent decades, and one of the new and widely used techniques in this field is sinus lift. This method is especially designed for patients who intend to implant dental implants in the upper jaw but are faced with a lack of bone. In this article, from the official website of **Dr. Najmeh Tadredarnjad** as an **Orthodontist in Mashhad**, we will fully examine what sinus lift is, when it is recommended, what its uses are, and how it is performed. **What is sinus lift?** A sinus lift is a dental surgery that is performed to increase the height of the bone in the back of the upper jaw. In this method, the surgeon raises the floor of the maxillary sinus and places bone powder or bone graft in the created space to provide a suitable platform for implant placement. **Why is it called a sinus lift?** Because in this method, the maxillary sinus, which is located near the upper molars, is physically "raised" to provide more space for bone grafting. This process helps to strengthen the jawbone so that the implant can be fixed in place. **Why is sinus lift performed?** One of the important prerequisites for implant placement is the presence of sufficient bone in the jaw. But in some cases, there is not enough bone for the following reasons: 1. **Long-term tooth loss:** After a tooth is extracted, the bone degenerates over time. 2. **Normal jaw bone structure:** Some people genetically have a narrow and small jaw. 3. **Proximity of the sinus to the upper jaw:** Sometimes the position of the sinus is such that there is not enough space for the implant. 4. Gum diseases: Chronic gum infections may cause bone loss. **Read more" The main causes of black children + treatment methods** In such a situation, sinus lift is suggested as an effective solution to increase bone volume. **Types of sinus lift methods** 1. ### **open sinus lift (traditional)** In this method, which is mostly used for severe bone deficiency, an incision is made on the gum, then a small window is opened in the upper jaw bone. The sinus membrane is gently lifted and the bone graft material is placed in the new space. This method requires more recovery time. 2. ### **Closed sinus lift (with balloon or osteotome technique)** This method is suitable for patients who have a milder bone deficiency. Through the placement of the implant, special tools are introduced to raise the sinus membrane. The advantage of this method is that in some cases, the implant can be installed at the same time. **Read more" Is it possible to do implant implantation with osteoporosis?** **Steps of sinus lift operation** 1. Consultation and review **radiology image (CBCT)**: First, the condition of the sinus and jaw bone is carefully checked. 2. Local anesthesia: Usually, the operation is performed under local anesthesia, but in certain cases, anesthesia may be needed. 3. Making an incision and raising the sinus membrane: the surgeon separates the sinus membrane from its floor and slowly raises it. 4. Addition of bone graft materials: These materials may be prepared from the patient's own bone, animal sources or synthetic. 5. Closing the surgical area and suturing 6. Recovery period: It usually takes a few months for the new bone to form and be ready for implantation. **Possible side effects of sinus lift** Sinus lift surgery is generally safe, but like any surgery, there may be complications, such as: - Swelling and bruising of the surgical area - Slight bleeding - Rupture or perforation of the sinus membrane (in rare cases) - Infection in the surgical area - Causing pressure or discomfort in the sinuses By carefully following the instructions after surgery and choosing a specialist dentist, the probability of these complications will be very low. #### Conclusion The sinus lift operation is an effective solution for those who intend to implant an implant in the upper jaw, but are unable to do so due to the reduction or insufficient bone volume. By elevating the sinus floor and adding bone graft material, suitable conditions for successful implant placement are provided. Although this operation is a surgical procedure, with proper care and selection of a specialist doctor, it can be associated with minimal complications and maximum success. ### **
