What Is Sinus Lifting?
Also known as sinus augmentation, sinus lifting is a surgical procedure used to increase bone volume in the upper jaw, particularly when there is insufficient bone height for dental implants. It is most commonly applied when changes are needed in the posterior maxilla (upper back jaw), and the existing bone structure is not dense or voluminous enough to support implants.
This technique allows for the creation of adequate bone mass and density, increasing the success rate of implants in the upper jaw.
How Is Sinus Lifting Performed?
Sinus lifting can be performed using either an open or closed (internal) approach, depending on the patient’s existing bone height.
Procedure Steps:
-
The patient is given local anesthesia, though general anesthesia may be used upon request or necessity.
-
A small incision (~2 mm) is made in the upper jaw to access the maxillary sinus.
-
The sinus membrane is gently lifted to create space.
-
This space is filled with bone graft material (often synthetic or bovine bone powder).
-
The area is then sutured closed.
Over time, the grafted area becomes new bone, making it possible to place a stable dental implant.
When Is Sinus Lifting Not Recommended?
As with all surgical procedures, sinus lifting has certain contraindications:
General Contraindications:
-
Previous radiation therapy to the maxillary sinus region
-
Uncontrolled systemic diseases (e.g., uncontrolled diabetes)
-
Excessive alcohol or tobacco use
-
Severe psychiatric disorders affecting compliance
Local Contraindications:
-
Active maxillary sinus infection or pathology
-
Chronic sinusitis or recurrent respiratory allergies
-
Untreated dental infections in the proposed implant area
Your dental surgeon will determine whether you are a candidate based on detailed clinical and radiographic evaluations.
When Can Implants Be Placed After Sinus Lifting?
This depends on the quantity and quality of existing bone:
-
If sufficient bone is present to stabilize the implant, sinus lifting and implant placement can be done simultaneously.
-
If not, a healing period of 3–6 months is necessary before placing the implants, allowing the graft to integrate and mature.
Open vs. Closed Sinus Lifting
Open Sinus Lift:
-
Used when bone height is less than 5 mm
-
Accessed via a larger opening through the gum and bone
-
Bone graft material is packed into the sinus floor
-
Takes approximately 45 minutes
-
Implants can be placed during the same session if adequate primary stability is achieved
Closed (Internal) Sinus Lift:
-
Suitable when at least 5 mm of bone height is present
-
Uses a specialized tool called an osteotome to gently lift the sinus from within the implant site
-
Less invasive and generally faster
-
Often done in conjunction with implant placement
-
May shorten overall treatment time by up to 6 months
Post-Procedure Care After Sinus Lifting
As a delicate surgical procedure, post-operative care is essential:
-
Avoid smoking to prevent delayed healing
-
Avoid sneezing or coughing forcefully, and keep your mouth open when sneezing
-
Avoid activities that create pressure in the sinuses, such as diving or strenuous exercise
-
Refrain from forceful spitting or rinsing for the first 24 hours
-
Follow all prescribed medications, including antibiotics and pain relievers
-
Gentle brushing can resume after 24 hours
Healing Time and Prosthetic Treatment
Full bone integration usually occurs within 6 months. Depending on individual healing, prosthetic procedures (implant crowns or bridges) are scheduled accordingly.
If implants are placed during the sinus lift, a temporary prosthesis may be provided during the healing period. Once osseointegration is complete, the final prosthetic work is initiated.
Is Sinus Lifting a Risky Procedure?
Sinus lifting is generally safe and effective when performed by an experienced oral surgeon. However, like any surgery, it carries risks if not done properly—such as infection or sinus membrane perforation. That’s why choosing a qualified and experienced dental professional is crucial for successful outcomes.
How Much Does Sinus Lifting Cost?
There is no fixed price for this procedure. Cost depends on:
-
The extent of bone grafting required
-
Clinic location and reputation
-
Surgeon’s experience
-
Type and brand of materials used
An accurate estimate can only be provided after a clinical and radiological evaluation.
