Sinus Lift Surgery

Losing teeth in the upper back jaw can lead to gradual bone loss over time. As the jawbone shrinks, the maxillary sinus naturally expands downward, leaving insufficient bone height for secure dental implant placement.

Sinus lift surgery, also known as sinus augmentation, is a highly successful oral surgical procedure that increases bone volume in the upper jaw. By gently lifting the sinus membrane and placing bone graft material underneath, a stable foundation is created for long-lasting dental implants.

At Dentsmile Clinic in Üsküdar, Istanbul, we combine advanced digital imaging, modern surgical techniques, and personalized treatment planning to provide safe and predictable sinus lift procedures for patients who require additional bone support before implant treatment.

What Is a Sinus Lift?

A sinus lift is a surgical procedure performed to increase the amount of bone in the upper back jaw by elevating the floor of the maxillary sinus.

The space created beneath the sinus membrane is filled with bone graft material, allowing new bone to develop naturally over time.

Once healing is complete, the regenerated bone provides adequate support for the placement of one or more dental implants.

Today, sinus lift surgery is considered one of the most reliable procedures in implant dentistry for patients with insufficient upper jaw bone.

What Is the Maxillary Sinus?

The maxillary sinuses are air-filled cavities located on both sides of the nose above the upper molars and premolars.

Under normal conditions, these sinuses play an important role in the respiratory system and facial anatomy.

However, after the loss of upper posterior teeth, two natural changes often occur:

• The jawbone gradually resorbs.

• The maxillary sinus expands downward (sinus pneumatization).

As a result, the remaining bone may become too thin to safely support dental implants.

Why Is a Sinus Lift Performed?

The primary purpose of sinus lift surgery is to create sufficient bone height for successful implant placement.

The procedure is commonly recommended when:

• The upper jaw does not have enough bone for implants.

• Teeth have been missing for many years.

• Significant bone loss has occurred after tooth extraction.

• The maxillary sinus has expanded into the implant area.

• Multiple implants are planned in the upper posterior jaw.

• Long-term implant stability requires additional bone support.

By increasing bone volume, sinus augmentation significantly improves the success rate of implant treatment.

Who Is a Candidate for Sinus Lift Surgery?

Sinus lift surgery is generally recommended for patients who wish to receive dental implants in the upper back jaw but do not have sufficient bone height.

You may be a suitable candidate if you:

• Have missing upper molars or premolars.

• Have inadequate bone volume in the posterior maxilla.

• Are in good general health.

• Are planning dental implant treatment.

A comprehensive clinical examination and digital imaging are necessary to determine whether the procedure is appropriate.

Evaluation Before Sinus Lift Surgery

Every treatment begins with a detailed diagnostic assessment.

Digital panoramic X-rays and, when necessary, 3D Cone Beam Computed Tomography (CBCT) allow the dentist to evaluate:

• Existing bone height.

• Bone density.

• Sinus anatomy.

• Thickness and condition of the sinus membrane.

• Implant positions.

• Overall surgical planning.

These examinations ensure maximum safety and treatment predictability.

How Is a Sinus Lift Performed?

Sinus lift surgery is usually carried out under local anesthesia, ensuring that patients remain comfortable throughout the procedure.

The surgeon first creates a small surgical access in the area where the implant is planned.

The sinus membrane is then carefully elevated without damaging it.

Bone graft material is placed beneath the lifted membrane, creating the additional bone volume required for future implant placement.

Depending on the amount of existing bone, the dental implant may be placed during the same appointment or after the graft has fully healed.

The procedure generally takes 30 to 90 minutes, depending on the complexity of the case.

Types of Sinus Lift Procedures

The appropriate technique depends primarily on the amount of remaining bone.

Open Sinus Lift (Lateral Window Technique)

An open sinus lift is recommended when there is severe bone loss.

A small window is created on the side of the upper jaw, allowing the surgeon to gently elevate the sinus membrane and place a larger amount of bone graft material.

This technique provides excellent results in advanced cases.

Closed Sinus Lift (Crestal Approach)

A closed sinus lift is suitable when moderate bone height remains.

The sinus floor is gently elevated through the implant site using specialized surgical instruments, and a smaller amount of bone graft is placed.

This minimally invasive technique often allows simultaneous implant placement.

Is Sinus Lift Surgery Painful?

No.

The procedure is performed under local anesthesia, so patients typically do not experience pain during surgery.

After the procedure, mild symptoms such as:

• Slight discomfort,

• Swelling,

• Tenderness,

• Minor bruising,

may occur for a few days.

These symptoms are generally temporary and can be effectively managed with prescribed medications.

Most patients report that recovery is easier than they anticipated.

Recovery After Sinus Lift Surgery

Some swelling and mild discomfort during the first few days are completely normal.

Bone regeneration usually requires 4 to 9 months, allowing the graft to integrate fully with the natural jawbone before implants are permanently restored.

Healing time varies depending on:

• The amount of bone graft placed.

• The graft material used.

• The patient's overall health.

• Smoking habits.

• Oral hygiene.

• Individual healing capacity.

Regular follow-up appointments allow your dentist to monitor the healing process.

Postoperative Care After a Sinus Lift

Following your dentist's instructions is essential for successful healing.

Patients are generally advised to:

• Avoid forcefully blowing the nose.

• Sneeze with the mouth open whenever possible.

• Avoid heavy physical activity for several days.

• Take prescribed medications exactly as directed.

• Refrain from smoking and alcohol consumption during healing.

• Maintain excellent oral hygiene.

• Attend all scheduled follow-up appointments.

These precautions help protect the surgical area and promote optimal bone regeneration.

Can a Sinus Lift and Dental Implant Be Performed at the Same Time?

Yes, in many cases.

If there is enough existing bone to provide adequate primary implant stability, the implant can often be placed during the same surgical appointment.

However, when bone volume is extremely limited, the sinus lift is completed first. After several months of healing, the implant is placed during a second procedure.

The treatment approach is determined individually based on each patient's anatomy and bone quality.

Sinus Lift Cost

The cost of sinus lift surgery varies depending on the individual treatment plan.

Several factors influence pricing, including:

• Whether an open or closed sinus lift is required.

• The amount of bone deficiency.

• The type of bone graft material used.

• Whether implant placement is performed simultaneously.

• Surgical complexity.

• Additional procedures required.

A precise treatment estimate can only be provided after a clinical examination and digital radiographic evaluation.

Frequently Asked Questions

Is sinus lift surgery safe?

Yes. When performed by experienced implant surgeons using modern techniques and proper planning, sinus lift surgery is considered a highly safe and predictable procedure.

When can dental implants be placed after a sinus lift?

Depending on the available bone, implants may be placed during the same surgery or after approximately 4 to 9 months of healing.

When can I return to normal daily activities?

Most patients resume normal daily activities within 1 to 3 days, although strenuous physical exercise should be avoided for a short period.

Is sinus lift surgery necessary for every implant patient?

No. It is recommended only for patients with insufficient bone height in the upper posterior jaw where additional bone support is required.
