Let me teach you something~I want to have dental implants, why do I need to move my maxillary sinus?

A hot search a few days ago:

The CPPCC National Committee member #suggested that the national centralized procurement of dental implant consumables be launched as soon as possible, and that dental implants be included in medical insurance as soon as possible#

Gaining strong support from netizens

This has sparked a discussion among netizens about dental implants.

We know that dental implant is actually a surgical procedure.

Simply put, an implant of a certain shape is selected and implanted into the alveolar bone as an artificial tooth root, and then a crown is installed on the part exposed in the mouth to obtain a shape and function similar to a natural tooth.

Patient: I have missing teeth in the upper row. Can I get dental implants?

Doctor: It can be done, but your alveolar bone condition is not very good, so you need a maxillary sinus lift.

"What is the maxillary sinus?"

"Sinus lift? Is this surgery?"

“Why is dental implant still related to the maxillary sinus?”

......

Today we are going to talk about the maxillary sinus.

1. What is the maxillary sinus?

"Sinus" means cavity. From a professional perspective, the maxillary sinus is an air-filled cavity located in the maxillary bone, similar to a horizontal cone. The roots of the maxillary posterior teeth are located below the maxillary sinus floor and are relatively close to the maxillary sinus floor. In some areas, the root tips are only separated from the maxillary sinus by a thin bone plate. Therefore, implantation of missing teeth in the maxillary posterior area is often closely related to the maxillary sinus.

2. The maxillary sinus has two significant characteristics

① After the teeth in this area fall out, the bone volume decreases rapidly. The maxillary sinus has a "gasification effect", which will make the maxillary sinus larger. Especially for patients who have been missing teeth for a long time, the enlargement of the maxillary sinus will further reduce the amount of bone available for implant surgery.

②Since the maxillary posterior teeth are close to the maxillary sinus, odontogenic inflammation can easily spread to the maxillary sinus and cause maxillary sinusitis. On the one hand, maxillary sinusitis is difficult to cure, and on the other hand, maxillary sinusitis will affect the prognosis of implant surgery.

In summary, implantation in the maxillary sinus area is relatively difficult and risky, but the incidence of tooth loss in this area is higher than in other areas of the mouth.

3. Why do you need a maxillary sinus lift?

We know that an important factor in the success of dental implant surgery is the alveolar bone. Implants cannot be implanted into cavities. Their implantation requires alveolar bone of sufficient height and width.

However, for some patients with long-term tooth loss, the available bone height in the maxillary sinus is lower, and the maxillary sinus pneumatization will also cause bone loss in the maxillary posterior teeth area. Therefore, when choosing a conventional length implant, due to insufficient bone height, a maxillary sinus lift is required to elevate the sinus floor mucosa and implant a certain amount of bone powder material to increase the alveolar bone height. Only when the bone height is reached can the implant be placed. This is like building a building. If the foundation is not solid, the building above must be dangerous.

At present, the most commonly used dental implant surgery for insufficient bone mass in the maxillary sinus area is the maxillary sinus lift, which includes the internal maxillary sinus lift and the external maxillary sinus lift.

4. Is sinus lift safe?

Whether a maxillary sinus lift is needed is recommended to be determined by a professional dentist after CBCT and other examinations. Not all patients require this surgery.

In current oral implantology, maxillary sinus floor augmentation is the most common method to improve vertical bone deficiency.

Evidence-based medicine shows that the success rate of maxillary sinus lift is very high. It is a relatively mature operation with high safety. Based on the current level of technology, it will not cause serious problems. It is also an effective way to solve the problem of insufficient bone mass in the posterior part of the maxilla, providing a guarantee for the successful function of future implants.

Warm reminder of two issues:

① Surgery involving maxillary sinus lifting must be performed when the maxillary sinus is in a non-inflammation state;

② For cases with progressive inflammation of the maxillary sinus, maxillary sinus lift can only be performed under the conditions of eliminating inflammation and strictly controlling recurrence.
