Frequently Asked Questions About Sinus Lifts

Why do I need a sinus lift before getting a dental implant?

When upper back teeth are missing for an extended period, the sinus cavity can expand downward, leaving insufficient bone height to support a dental implant. A sinus lift adds bone to the area, creating the foundation needed for a stable, long-lasting implant. Without adequate bone volume, an implant would lack the support required to function properly over time.

How long does a sinus lift procedure take?

Most sinus lift procedures take between one and two hours, depending on whether one or both sides are being treated and whether the implant is placed during the same visit. Your periodontist will review your specific treatment plan in advance so you know exactly what to expect on procedure day.

Is a sinus lift painful?

The procedure is performed under local anesthesia, so you should not feel pain during surgery. You may sense pressure or movement, which is normal. After the procedure, most patients experience mild to moderate discomfort similar to a sinus headache, which is typically managed with prescribed or over-the-counter pain relievers.

How long is recovery after a sinus lift?

Gum tissue generally heals within approximately two weeks, while the underlying bone graft requires several months to fully integrate before an implant can be placed. During recovery, patients are advised to avoid blowing their nose, strenuous activity, and pressure on the surgical site to protect the graft material.

Does insurance cover sinus lift surgery?

Coverage varies depending on your dental insurance plan. Some plans cover sinus lifts when deemed medically necessary for implant placement, while others may not. Our team offers complimentary insurance verifications and can help you understand your benefits and explore payment plan options before moving forward.

Can a sinus lift and implant be placed at the same time?

In some cases, yes. If sufficient existing bone is present to provide initial implant stability, both procedures can be performed in a single visit. When bone loss is more significant, a staged approach allows the graft to fully mature before implant surgery. Your periodontist will determine the right approach based on your 3D imaging results.

What is a Sinus Lift?

What is a Sinus Lift?

A sinus lift is a surgical procedure that lifts the floor of the maxillary sinus cavity in order to make room for a dental implant. Sinus lift procedures take place in the upper jaw, in the region of molars or premolars. The maxillary sinus cavity is an air space above the upper back teeth and behind the cheekbones. It serves to lighten the skull and humidify and filter the air we breathe.

When the upper back teeth, which sit below the sinus cavity, are missing, the sinus often enlarges (called pneumatization) and shortens the amount of bone available in the upper jaw. Sometimes this can happen while the teeth are in the roots. Molars have 3 roots, and sometimes the sinus grows downward between the roots. This loss of bone affects the surgeon’s ability to replace the missing tooth with a dental implant. 

The inside of the sinus cavity is lined with a thin membrane, which can be lifted in order to accommodate a bone graft that provides enough height and width of bone to support a dental implant. Your surgeon can manipulate this membrane through a small “window” on the cheek side of the upper jaw (called a lateral window) or through the surgical opening for the dental implant (sometimes referred to as a “bump”).

Reasons for Needing Sinus Lift Surgery

Several reasons may lead to the need for a sinus lift before undergoing dental implant surgery. Inadequate bone height in the upper jaw, often due to bone loss from periodontal disease, tooth loss, or anatomical issues, is one of the most common reasons. If your jawbone lacks enough bone to support a dental implant, a sinus lift may be necessary to ensure successful implant placement. Also, if the maxillary sinus is too close to the jawbone, this could further complicate the implant procedure.

You may also need a sinus lift if trauma or previous dental work compromised the bone structure. In such cases, your oral surgeon will assess the available bone and determine whether a sinus lift is a viable option for you.

 

Postoperative Care for Sinus Lifts

After undergoing a sinus lift, patients will need to follow specific postoperative care instructions to ensure optimal healing. This includes avoiding strenuous activities, refraining from blowing the nose, and taking prescribed medications as directed. Keeping the surgical site clean and managing discomfort through recommended pain relief strategies are also essential.

 

The Importance of Follow-Up Visits with Your Dentist

Follow-up visits with the dentist are important after a sinus lift procedure. These appointments allow the dental specialist to assess the healing of the bone graft and the condition of the sinus membrane. Based on the progress observed during these visits, the dentist will determine the appropriate timeline for proceeding with dental implant surgery, if needed.

What does the Sinus have to do with Dental Implants?

When we replace missing teeth with dental implants, the long-term stability directly correlates to the size of the dental implants. Logically, you would never want to place a large molar-sized crown on top of a short, narrow implant. The goal of dental implants is to replace the tooth’s root and support normal chewing forces. We achieve more stability with a long, large-diameter implant, but this is possible only when enough jawbone is present. By lifting the floor of the sinus cavity, we are capable of increasing the height of bone and placing a longer, more stable dental implant.

Why do Some Implants Require a Sinus Lift?

In general, the longer an upper back tooth is missing, the greater chance there is for enlargement of the sinus cavity. Many people wait longer than the recommended time frame after a tooth extraction to proceed with the dental implant, which decreases the available bone height. Certain anatomical variations also predispose some people to lower sinus floors than others. 

When planning the replacement of a missing tooth with a dental implant, we place a high priority on pre-operative planning. Our planning includes, when indicated, a three-dimensional image, which allows us to take precise measurements of the bone in the site of the proposed implant and foresee the need for a sinus lift procedure. We base the decision on the current height of bone available as compared to the most favorable size of the dental implant, which is necessary to bear that tooth’s chewing force.

What Can I Expect from a Sinus Lift Procedure?

During the sinus lift procedure, you should not feel any pain. Local anesthetic provides numbness to the site of surgery. It’s important to note that local anesthetic does not remove the sensation of pressure, so you may feel tapping or pushing behind your cheekbone. 

Some sinus lift surgeries will require stitches, and others do not. If the sinus lift procedure takes place in conjunction with the placement of the dental implant, you probably will not need any stitches. If your jaw requires a lateral “window” sinus lift, the surgeon will use stitches to close the surgical site.

After the procedure, you may have post-operative discomfort and pressure-type pain, like a sinus headache. A dull throbbing or ache is normal, and your surgeon will help you manage any pain with medication.

How Long is the Recovery from a Sinus Lift?

The healing of the gum tissues takes about two weeks in healthy adults. Gums close and return to normal much more quickly than the underlying bone. After this initial healing phase, you can return to normal eating, drinking, brushing and flossing.

The underlying bone requires a longer healing period. It takes several months for your natural bone to grow into the grafted bone material. Your surgeon will monitor this closely with dental x-rays. This healing time can take three to six months. This is the same length of time required for the bone to firmly attach to the dental implant. 

Only after your surgeon confirms the stability of the dental implant can you proceed with building the crown atop the implant and resuming normal chewing in this area.
