Sinus Lift Using Lateral Window Approach with Placement of 2 Implants

Sinus Lift Using Lateral Window Approach with Placement of 2 Implants


Sinus lift is a surgical procedure used to increase bone mass in the upper jaw to make it suitable for implant placement.

The Lateral Window Approach

The lateral window approach is a technique used in the sinus lift procedure. It involves creating a small window in the side of the upper jaw to access the sinus cavity.


The procedure begins with the administration of local anesthesia to ensure the patient’s comfort. An incision is made in the gum tissue to expose the underlying bone. Then, a small window is created in the lateral wall of the sinus using specialized surgical instruments.

The sinus membrane is carefully lifted, creating a space between the membrane and the bone. This space is then filled with bone graft material, which serves as a scaffold for new bone growth.

The bone graft material can be obtained from the patient’s own body (autogenous graft), from a donor (allograft), or from synthetic materials (alloplast). The choice of graft material depends on the patient’s individual needs and the surgeon’s preference.

After placing the bone graft material, the surgical site is closed with sutures, and the healing process begins. Over time, the bone graft integrates with the surrounding bone, creating a solid foundation for the placement of dental implants.

Placement of Two Implants

After the sinus lift procedure, two dental implants are placed in the jawbone to support dental restorations. Implants are titanium posts that are surgically inserted into the jawbone to act as artificial tooth roots.

The implants provide stability and support for various dental restorations, such as crowns, bridges, or dentures. They fuse with the surrounding bone through a process called osseointegration, ensuring a strong and long-lasting foundation for the prosthetic teeth.

Benefits of Two Implants

Placing two implants offers several advantages. First, it provides adequate support for the dental restorations, ensuring proper function and aesthetics.

Second, two implants distribute the biting forces more evenly, reducing the stress on individual implants and enhancing their longevity.

Lastly, two implants can help maintain the natural shape and contours of the jawbone, preventing bone loss and preserving the facial structure.


Sinus lift using the lateral window approach with placement of two implants is an effective surgical procedure for increasing bone mass in the upper jaw. It allows for the successful placement of dental restorations and improves the overall oral health and quality of life for individuals requiring dental implant treatment.

Frequently Asked Questions (FAQs)

1. How long does it take to recover from a sinus lift procedure?

The recovery time after a sinus lift procedure can vary from person to person. It generally takes several months for the bone graft to integrate with the natural bone. Your surgeon will provide specific post-operative instructions to ensure a smooth and successful recovery.

2. Are there any risks or complications associated with sinus lift surgery?

As with any surgical procedure, sinus lift surgery carries some risks and potential complications. These can include infection, bleeding, swelling, sinusitis, and damage to surrounding structures. However, with proper technique and post-operative care, the risk of complications can be minimized.

3. Can anyone undergo a sinus lift procedure?

Not everyone is a suitable candidate for a sinus lift procedure. A thorough examination and evaluation by a qualified oral and maxillofacial surgeon are necessary to determine if the individual has sufficient bone height and volume in the upper jaw to support dental implants.

4. Can the sinus lift procedure be performed simultaneously with dental implant placement?

In some cases, the sinus lift procedure and dental implant placement can be performed simultaneously, especially if there is adequate bone present to support immediate implant placement. However, each patient’s situation is unique, and your surgeon will determine the most appropriate treatment plan for you.

5. Does the sinus lift procedure cause any pain?

During the sinus lift procedure, local anesthesia is administered to ensure a pain-free experience. After the surgery, you may experience some discomfort, swelling, or mild pain, which can be managed with prescribed pain medications. Your surgeon will provide detailed post-operative instructions to help alleviate any discomfort.
