The difference between open and closed sinus lift Sinus lift surgery involves going through the mouth and making an incision in the gum line to expose the jawbone. But the difference between open and closed sinus lift is the amount of incision and the technique used to increase the jawbone. Below we explain each of the techniques used separately so that you can learn more about the difference between an open and closed sinus lift: In open sinus lift surgery, an incision is made in the gum tissue to expose the side wall of the maxillary sinus. A small window is then created in the side bone so that the dentist can access the sinus cavity. In the open sinus lift technique, a special coarse diamond bur is used to thin the side wall of the sinus. The reciprocating movements of the bur reveal the sinus membrane. The sinus membrane (Schneider's membrane) is then gently lifted and bone graft material is placed underneath to increase the height of the bone. Finally, the incision is closed and the gum tissue is sutured. After a recovery period of 4 to 6 months, the dental implant is placed. > **English text:** > > "Open sinus lift: A technique for performing subantral augmentation where an opening (window) is created in the lateral wall of the maxillary sinus. Through this window, the mucous membrane of the maxillary sinus (Schneiderian membrane) is carefully elevated using specialized instruments, and the resulting space is filled with osteoplastic material." > > **Persian translation**: > > "Open sinus lift is a procedure to increase the bone volume under the maxillary sinus in which a small window is created in the side wall of the maxillary sinus. Through this window, the mucous membrane of the sinus (Schneider's membrane) is carefully raised using specialized tools, and the created space is filled with bone-forming material. > > Quoted from uniqa.dental website Compared to open sinus lift surgery, closed sinus lift is a minimally invasive procedure that is performed through the existing implant site. A small hole is created in the jawbone from where the implant will be placed. The sinus membrane is gently lifted using specialized instruments. The bone graft material is inserted through the same hole. Dental implants are placed immediately or after a short recovery period. Therefore, the difference between open and closed sinus lift is in the amount of incision made, the tools used and the time of the implant. In open sinus lift surgery, the implant is implanted after at least 6 months, but in closed sinus lift surgery, the base of the implant is placed in the jaw bone in the same session. Therefore, if the jaw bone loss is not severe, closed sinus lift surgery is suitable for people who need quick treatment. > If large and complex surgeries are a concern for you, a short base implant can be a minimally invasive solution that requires fewer incisions. To learn more about this method, we suggest reading this article. **Video of open sinus lift and three units of upper jaw implants and four units of lower jaw implants** Comparing the disadvantages of open and closed sinus lift In the following, we point out the disadvantages of each surgical method and examine the difference between open and closed sinus lift in terms of disadvantages: #### Disadvantages of open sinus lift include: - **More Damage**: May cause large bruising and swelling in areas of the face, such as under the eyes and neck. - **Chtear of the sinus membrane**: The possibility of perforation of the Schneiderian membrane has been reported as 19 to 25%. - **long recovery period**: requires more recovery time. - **More pain**: The pain and discomfort after the operation is more. - **Risk of bleeding**: The risk of bleeding is higher than a closed sinus lift. - **More infection**: The possibility of infection is more due to perforation of the membrane. - **Opening of wounds and stitches**: There is a possibility of opening of stitches and wounds. > Read about full open sinus lift surgery #### Disadvantages of closed sinus lift include: - **Limited vision**: The dentist has little vision of the surgical area, which makes it difficult to detect problems during the operation. - **Risk of displacement of graft and implant**: The possibility of displacement of graft and implant base is higher. - **requires high skill**: This surgery requires high skill and experience. - **Limitation in use**: This method can be used only in cases where the height of the bone is sufficient (at least 5 mm). Difference between open and closed sinus lift in benefits In the following, we point out the advantages of each surgical method and examine the difference between open and closed sinus lift in terms of advantages: #### Advantages of closed sinus lift: - **Less invasive**: It is a minimally invasive surgery that causes less swelling and pain. - **Shorter duration**: Less surgery time and less bleeding. - **Surgery combination**: both sinus lift and implant implantation are performed in one session. - **faster recovery time**: has a shorter recovery period. - **maintaining the integrity of the sinus**: less damage is done to the sinus membrane. - **Suitable for moderate bone loss**: It is suitable for people with moderate bone loss. > Read more: sinus lift cost, price list + table #### Advantages of open sinus lift: - **Significant increase in bone height**: It is possible to significantly increase the height of the jaw bone. - **Suitable for severe bone loss**: It is suitable for people who have severe bone loss or are toothless. - **preserving facial structure**: helps to maintain facial structure and prevent facial depression. - **Increasing implant stability**: due to the increased jaw bone, implant stability improves. - **better view of the surgeon**: the incision gives the surgeon a better view to place the graft material. > English text: > > "The undoubted plus of the closed sinus lifting is that if your initial bone volume was 3-4 mm, then the implant can be installed on the same day, immediately after the augmentation operation. In addition, in contrast to the open one, the closed sinus lifting practically does not leave behind bruises and swellings, and the recovery process is much easier and faster in general. > > Farsi translation: > "The undoubted advantage of the closed sinus lift method is that if your initial bone volume is about 3 to 4 mm, the implant can be placed the same day and immediately after the bone augmentation procedure. In addition, unlike the open method, in the closed method there is almost no bruising and swelling, and the healing process is generally much easier and faster." > > Quoted from smileoffice website Cost comparison Another difference between open and closed sinus lift is the cost of both methods. The cost of a sinus lift operation usually depends on the complexity, the surgeon's expertise and the location. A sinus lift is more invasive and complicated and usually requires a larger incision and more bone graft material. Open sinus lift surgery is usually more expensive due to longer surgery time, more materials, and longer post-operative care. The average price of open sinus lift surgery is between 10 and 15 million Tomans. A closed sinus lift is less invasive and is performed through the implant site with smaller incisions and less graft material. Therefore, it is natural that it costs less. > If the bone loss of the upper jaw is to the extent that the sinus lift is not enough, more advanced surgeries such as (complete upper jaw implant) will be required. If we want to examine the difference between open and closed sinus lift in terms of costs, we must mention that open sinus lift surgery requires more equipment, so it is performed in many well-equipped clinics that use advanced and modern equipment, which increases the cost of this procedure. **final word** In this article, we mentioned the most important difference between open and closed sinus lift. Both closed and open sinus lifts are effective techniques for increasing bone volume in the maxilla, but they meet different needs. Closed sinus lift surgery is a minimally invasive procedure and ideal for patients with moderate bone loss, it causes much less damage to the gum tissue. The dentist makes a hole to install the implant and through the same hole, with special surgical tools, bone material is inserted into the space. > For those who are looking for more specialized information on this matter and its processes, we suggest not to miss the article (sinus lift surgery) Sometimes, after closed sinus lift surgery, a dental implant base can be placed in the jawbone on the same day. While open sinus lift surgery is a more extensive procedure and more suitable for patients who have a lot of bone loss. Patients need a longer period of rest after open sinus lift surgery to fully recover. But the recovery period in closed sinus lift surgery is less. After both surgeries, it is necessary to follow care tips. Take antibiotics and painkillers prescribed by the dentist regularly to reduce the risk of complications. You should not eat anything for two hours after the operation. Consuming spicy, hard and hot foods and drinks is prohibited.
