Sinus Lift before placing the Dental Implant attention to many points before it is done so as not to cause danger. Sinus Lift is indicated for cases where customers want to have Dental Implant but have limited jawbone, insufficient jawbone density, thin jaw waves…
What is the Sinus Lift method?
Sinus Lift is a surgical method aimed at increasing bone size, making the jawbone eligible for implant placement.
On both the right and left sides of the maxillary bone, there will be an internal maxillary sinus. People who have lost teeth for a long time will gradually lose jawbone and alveolar bone.
Bone loss causes the maxillary sinuses to become lower than normal, making it difficult to place the implant into the jawbone.
People with bone loss need a sinus lift before the Dental Implant process to increase bone volume, helping the jawbone to be qualified in terms of height, bone density, and bone volume.
Then, the installation of the Dental Implant into the jawbone is more convenient, the Implant post integrates the jawbone better, and is supported more firmly.
Some common objects that are prescribed by doctors to lift sinuses are:
- The patient has jawbone loss, and at the same time
- Patients who have lost their teeth for a long time, the density of the jawbone is thin, the sinus bone is completely backward
- Patients who have lost their teeth for a long time, causing the jawbone to expand, are not eligible for implant placement.
Sinus Lift methods
The two most common methods of Sinus Lift that are trusted by doctors are Open Sinus Lift and Closed Sinus Lift:
Open Sinus Lift
Open Sinus Lift is also known as Lateral Window Sinus Lift. In this technique, the doctor will make an incision in the gum next to the missing tooth, then add more jawbone through the incision site.
Open Sinus Lift is often applied to patients who have lost teeth for a long time, causing severe jawbone loss, jawbone degeneration. The most obvious manifestation is that the jawbone is deeply lowered, expanding in volume.
Before conducting an Open Sinus Lift, the doctor needs to clean and disinfect the oral cavity, then make an incision in the lining of the periosteum, the position along the ridge of the jaw in the area of the missing teeth.
At that time, the bone surface to be implanted will be partially exposed, the doctor only needs to make a slight impact, lift the periosteum and artificially graft bone until there is enough bone volume needed.
When the jaw bone has enough bone mass, the patient just needs to wait for the wound to recover to be able to proceed with the Implant.
Closed Sinus Lift
Closed Sinus Lift is a method of raising the sinuses from the inside, through an Implant hole and does not require too much surgery like Open Sinus Lift.
The Closed Sinus Lift technique requires an incision from the gums to the maxillary sinus area to be lifted, then make a small hole to gradually raise the sinus. The implanted jaw bone will be filled in through the space between the raised sinus membrane and the old jaw bone.
Closed Sinus Lift is performed for those who have long-term bone loss, the jawbone disappears, the jaw sinus has no bone to support.
When to perform Sinus Lift?
For normal cases where the jawbone density is guaranteed, the doctor will appoint the Implant surgery to be performed without the need for Sinus Lift surgery. Sinus Lift surgery is only performed when encountering cases such as:
- The patient has lost teeth for a long time, the jawbone has gradually disappeared
- The jawbone may not have disappeared, but the bone mass is lacking
- Patients who have lost their teeth for a long time, causing the maxillary sinuses to put pressure on the upper jawbone. At this time, the upper jaw bone is gradually dissipated, enlarged, not eligible for Dental Implant technique.
- The patient has not had jawbone resorption, but the original jawbone structure does not have enough bone density, and the jawbone volume is small.
Some cases are contraindicated with bone grafting sinus lift technique such as:
- Patients suffering from sinusitis or other sinus diseases
- Patients with diseases related to hemophilia
- Patients with underlying diseases of heart disease, diabetes, blood pressure
- Patients who smoke, use stimulants before surgery
Sinus Lift is an effective method to help the Dental implant procedure take place more smoothly, bringing higher dental restoration results. The process of Sinus Lift needs to be performed at facilities that ensure a high level of equipment and professional qualifications. Customers should pay attention to choose the right dental address.
