What Is Maxillary Sinus Lift Surgery in Implant Treatment at a Daechi-dong Dental Clinic?

Implant Maxillary Sinus Lift, Yonsei Jeongwon Dental Clinic

Hello, this is Yonsei Jeongwon Dental Clinic in Daechi-dong.

Generally, implant treatment is considered when a permanent tooth has been lost, or when a tooth has been severely damaged by cavities, gum disease, or other conditions to the point that restorative treatment is no longer possible. An implant is a treatment method that restores function and esthetics similar to natural teeth by directly placing an artificial root into the jawbone to replace the missing tooth and then connecting an artificial tooth, such as a crown, on top of it.

When patients visit us for an implant consultation after losing an upper molar, we often explain that another procedure may need to be performed at the same time as the implant surgery. One of the terms we explain at this time is the "maxillary sinus." The maxillary sinus is a pyramid-shaped empty space inside the upper jawbone, and it is easy to understand if you think of it as an air-filled pouch. Some people mistakenly think that because implant prices have come down a lot compared with the past, the clinic is intentionally recommending additional procedures. So in this post, we would like to explain what the maxillary sinus is and in what cases the procedure is truly necessary.

What Is the Maxillary Sinus?

It is an air pouch located near the nose and cheek area of the face, and it is one of the paranasal sinuses in our body. This space is directly connected to the nose and serves several functions, such as helping airflow during breathing and regulating resonance in the voice. In addition, the inner wall of the maxillary sinus is covered with a mucous membrane, which also helps filter external substances such as bacteria. The size and shape of the maxillary sinus vary from person to person.

The Positional Relationship Between the Maxillary Sinus and the Roots of the Upper Molars

Because the maxillary sinus is an important part of our body, we must be as careful as possible not to damage the air pouch when placing implants in the upper molar area. Therefore, if there is insufficient upper jawbone and the distance to the maxillary sinus is close, implant placement can be considered a very difficult procedure.

Then what should be done if a tooth has been lost and the jawbone has resorbed, leaving insufficient bone for implant placement? In such cases, a "maxillary sinus lift" is performed to secure enough bone between the maxillary sinus and the implant site for stable implant placement.

What Is a Maxillary Sinus Lift?

When an implant is planned for the upper jaw where the maxillary sinus is located and there is insufficient bone in that area, this procedure is performed to secure more bony space between the maxillary sinus and the implant site.

If you look at the illustration above, the yellow area is the bone-filled space, and the empty space above is the area called the maxillary sinus. As you can see in the image, there is not enough bony space for an implant to be placed.

�

If implant surgery is performed forcefully in such a case, the maxillary sinus may be perforated, causing a feeling of air passing between the nose and mouth, persistent nosebleeds, or symptoms such as water passing from the mouth into the nose. Because of these possible side effects, a "maxillary sinus lift" is needed to elevate the lowered maxillary sinus space upward.

How Is a Maxillary Sinus Lift Performed?

�

The thin membrane covering the maxillary sinus is lifted upward, the space is filled with artificial bone to secure bone for implant placement, and then the implant is placed. In this way, a maxillary sinus lift is performed together with implant surgery in the upper molar area. This procedure can be described as a surgery performed to strengthen the connection between the implant and the jawbone and extend the life of the implant.

�

Because a maxillary sinus lift is a technically demanding procedure, the medical staff at Yonsei Jeongwon Dental Clinic actively strives to perform implant treatment with minimal side effects through sufficient preoperative record review (preoperative CT & postoperative CT) and radiographs (PA) taken during surgery. Please feel free to visit the clinic and receive a consultation!

At Yonsei Jeongwon Dental Clinic, we do not recommend a maxillary sinus lift if it is not necessary after a precise CT analysis.
