Sinus Lift for Dental Implants in Forest Hills, Queens

Article written: November 2, 2026

Dental implants offer a long-term way to replace missing teeth, but successful implant placement depends on having enough healthy jawbone to support them. For patients who have lost upper back teeth, insufficient bone beneath the sinus cavity can sometimes make implant placement more complicated.

Fortunately, a periodontal procedure called a sinus lift, also known as sinus augmentation, may help create the bone needed for dental implants.

At Your Gum Specialist in Forest Hills, Queens, Dr. Prabha Krishnan provides advanced periodontal and implant-related care, including sinus augmentation and bone grafting.

If you have been told that you do not have enough bone for an upper dental implant, understanding how sinus lift surgery works can help you make an informed decision about your treatment options.

Key Takeaways: Sinus Lift Surgery

• A sinus lift increases available bone height in the upper back jaw, usually in preparation for dental implants.
• The procedure gently elevates the sinus membrane and places bone graft material beneath it.
• Sinus augmentation may be recommended after tooth loss, periodontal bone loss, or changes in sinus anatomy.
• Dental implants may sometimes be placed during the same procedure, but other patients require a separate healing period.
• Healing and bone development take several months, depending on the individual case.
• A periodontal examination and appropriate imaging determine whether a sinus lift is necessary.

What Is a Sinus Lift?

A sinus lift is a surgical bone augmentation procedure that increases the amount of bone available in the upper jaw near the premolars and molars.

The maxillary sinuses are air-filled spaces located above the upper back teeth. A thin membrane lines the inside of each sinus. When there is insufficient bone between the mouth and sinus cavity, a periodontist may gently elevate this membrane and place bone graft material beneath it.

Over time, the grafted area supports new bone formation, potentially creating a stronger foundation for future dental implant placement.

According to the American Academy of Periodontology, sinus augmentation is designed to address insufficient bone in the upper back jaw and improve the available foundation for dental implants.

Why Would Someone Need a Sinus Lift Before Dental Implants?

The upper back jaw presents unique challenges for implant treatment. The bone in this area may be relatively thin, and the sinus cavity sits directly above the roots of the upper premolars and molars.

After teeth are lost, the supporting jawbone can gradually shrink. At the same time, the sinus cavity may expand into the space previously occupied by bone, a process known as sinus pneumatization.

As a result, there may not be enough vertical bone height to accommodate a dental implant safely and securely.

Common reasons for insufficient bone include:

• Long-term tooth loss: The jawbone may gradually resorb after an upper molar or premolar is lost.
• Periodontal disease: Advanced gum disease can damage the bone supporting natural teeth.
• Sinus anatomy: Some patients naturally have a larger sinus cavity or less bone beneath it.
• Previous dental infection: Infection around an upper tooth may contribute to localized bone destruction.
• Trauma or difficult extractions: Injury or tooth removal may leave an area with inadequate bone volume.

Patients with a history of periodontal disease may require additional treatment to control infection before implant-related bone reconstruction begins.

How Is a Sinus Lift Performed?

Sinus lift surgery is tailored to the patient’s anatomy and the amount of bone needed. Although techniques vary, the general process involves creating space beneath the sinus membrane and placing bone graft material to support new bone formation.

1. Examination and treatment planning

The periodontist evaluates the teeth, gums, available bone, and sinus anatomy. Dental imaging helps determine how much bone is present and whether a sinus lift is necessary.

Three-dimensional imaging, such as a cone-beam CT scan (CBCT), may be used when clinically appropriate to assess bone height, sinus anatomy, and the proposed implant position.

2. Local anesthesia

The surgical area is numbed to help keep the patient comfortable. Additional anesthesia or sedation options may be discussed when appropriate.

3. Access to the sinus floor

Depending on the selected technique, the periodontist creates access to the sinus floor through the jawbone or through the planned implant site.

4. Elevation of the sinus membrane

The membrane lining the sinus is carefully lifted to create additional space between the sinus cavity and the existing jawbone.

5. Placement of bone graft material

Bone graft material is placed into the newly created space. This material acts as a scaffold that supports the development of new bone during healing.

6. Closure and healing

The surgical site is closed as appropriate, and the grafted area is allowed to heal. In some cases, the dental implant can be placed during the same appointment. In others, implant placement occurs after sufficient bone has developed.

The American Association of Oral and Maxillofacial Surgeons provides additional patient information about sinus augmentation and its role in dental implant preparation.

Different Types of Sinus Lift Procedures

Two common approaches are used for sinus augmentation. The appropriate technique depends on the amount of existing bone, the desired increase in bone height, and the planned implant position.

Lateral window sinus lift

A lateral window approach creates a small opening in the side of the upper jawbone to access and elevate the sinus membrane. This technique may be recommended when a greater increase in bone height is needed or when the anatomy requires more direct access.

Transcrestal or internal sinus lift

An internal sinus lift approaches the sinus floor through the ridge where the dental implant will be placed. It may be suitable when a smaller amount of additional bone height is needed and sufficient existing bone is available.

Neither approach is universally better. The periodontist selects the technique based on clinical findings and the treatment goals.

What Type of Bone Graft Is Used During a Sinus Lift?

Different grafting materials can be used during sinus augmentation. The appropriate choice depends on the size of the defect, the surgical technique, patient-specific factors, and the clinician’s treatment plan.

• Autograft: Bone obtained from the patient’s own body.
• Allograft: Processed human donor bone obtained through a tissue bank.
• Xenograft: Processed graft material derived from another species, commonly bovine sources.
• Synthetic graft: Biocompatible materials designed to support bone regeneration.

Your Gum Specialist offers bone grafting services for several periodontal and dental implant applications. A sinus lift is one specific type of bone augmentation procedure.

Sinus Lift vs. Ridge Augmentation: What Is the Difference?

Both procedures increase available bone for dental implant treatment, but they address different anatomical problems.

For example, a patient who has lost an upper molar may need a sinus lift because the remaining bone beneath the sinus is too short. Another patient may need ridge modification because the jawbone is too narrow to accommodate an implant.

Some patients may require both procedures, while others may not need bone grafting at all.

How Long Does It Take to Heal After a Sinus Lift?

Healing after sinus lift surgery occurs in stages. Initial soft-tissue healing generally takes considerably less time than the development and maturation of new bone.

The American Academy of Periodontology notes that grafted bone may be allowed to develop for approximately four to twelve months before dental implants are placed in some cases. Other patients may be able to receive implants at the same time as the sinus lift.

The timeline depends on:

• The amount of bone needed
• The surgical technique
• The type and volume of graft material
• The amount of existing bone
• Individual healing response
• Smoking or nicotine use
• Medical conditions that may affect healing
• Whether the implant is placed during the same procedure

Patients should understand that the gum tissue may appear healed before the underlying graft has fully matured. Follow-up appointments and imaging help determine when the next stage of treatment can begin.

What Is Recovery Like After Sinus Lift Surgery?

Some swelling, tenderness, bruising, nasal congestion, or minor bleeding may occur after sinus augmentation. These symptoms typically improve as healing progresses, although recovery varies from patient to patient.

Protecting the sinus membrane and graft during early healing is particularly important because pressure changes in the nose and sinus cavity can disturb the surgical site.

Patients may be instructed to:

• Avoid blowing the nose for the period specified by the periodontist
• Sneeze with the mouth open rather than suppressing a sneeze
• Avoid smoking, vaping, and nicotine products
• Avoid drinking through a straw when instructed
• Eat soft foods and avoid chewing directly over the surgical area
• Take prescribed medications exactly as directed
• Avoid activities that place excessive pressure on the surgical site
• Attend all scheduled follow-up appointments

Your Gum Specialist provides detailed sinus lift post-procedure instructions for patients undergoing treatment.

Cambridge University Hospitals also provides a useful patient guide to sinus lift procedures, including information about recovery, possible complications, and precautions during healing.

Are There Risks Associated With Sinus Lift Surgery?

Like any surgical procedure, sinus augmentation carries potential risks. Although many patients heal without significant complications, it is important to understand what may occur.

Possible complications include:

• Sinus membrane perforation or tearing
• Infection
• Excessive bleeding or swelling
• Persistent sinus discomfort or congestion
• Displacement or loss of graft material
• Insufficient bone formation
• Delayed healing or the need for additional treatment

Patients should promptly contact their treating clinician if they develop fever, worsening swelling, severe or increasing pain, unusual drainage, persistent bleeding, or other concerning symptoms after surgery.

A thorough evaluation, appropriate surgical planning, and careful adherence to post-operative instructions help reduce avoidable complications, but no surgical result can be guaranteed.

Can Dental Implants Be Placed Without a Sinus Lift?

Yes. Not every patient with missing upper back teeth needs sinus augmentation.

If sufficient bone is available, an implant may be placed without additional grafting. In certain situations, the periodontist may also consider alternative implant dimensions, positioning, or restorative options.

The most appropriate treatment depends on the available bone, sinus anatomy, number of missing teeth, bite, and final restorative plan.

Rather than assuming a sinus lift is necessary, the first step is a comprehensive examination and appropriate imaging to determine whether additional bone is actually required.

Why See a Periodontist for Sinus Augmentation?

Periodontists receive advanced training in the gums, jawbone, regenerative procedures, and dental implant treatment. Sinus augmentation requires careful evaluation of the upper jaw, the available bone, the sinus membrane, and the planned implant position.

Frequently Asked Questions About Sinus Lift Surgery

What is a sinus lift in dentistry?

A sinus lift is a bone grafting procedure that increases bone height in the upper back jaw by gently elevating the sinus membrane and placing graft material beneath it, usually to prepare for dental implants.

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

You may need a sinus lift if there is not enough bone between the upper jaw and sinus cavity to support a dental implant. This can happen after tooth loss, periodontal disease, or natural changes in sinus anatomy.

Is a sinus lift painful?

Sinus lift surgery is generally performed with local anesthesia. Some soreness, swelling, or pressure may occur afterward, but discomfort varies with the surgical technique and individual healing response.

How long after a sinus lift can I get dental implants?

Some patients can receive implants during the same procedure. Others may need several months of bone healing before implant placement. The timeline depends on the available bone, grafting technique, and healing progress.

What is the difference between a sinus lift and a bone graft?

A sinus lift is a specific type of bone grafting procedure performed in the upper back jaw beneath the maxillary sinus. Other dental bone grafts may rebuild bone width, height, or contour in different areas of the jaws.

Can a sinus lift fail?

Yes. Possible complications include infection, membrane perforation, graft problems, or inadequate new bone formation. Careful planning and post-operative care help reduce risks, but additional treatment may sometimes be necessary.

How do I know if I need a sinus lift?

A periodontist can determine whether sinus augmentation is necessary through a clinical examination and appropriate imaging. The evaluation measures available bone height and assesses the relationship between the proposed implant and sinus cavity.
