When teeth are lost in the upper back jaw, the bone often shrinks over time, leaving too little height for dental implants. Just above this region lies the maxillary sinus, an air-filled cavity close to the roots of the upper molars and premolars. When bone is lost, this sinus can expand downward into the empty space, further reducing the bone needed to stabilize implants.
At Dr. Geoffrey Rubinshtein Periodontics & Implantology, we provide sinus lift procedures that carefully raise the sinus membrane and add bone graft material, creating the strong foundation required for successful dental implant placement.
A sinus lift, also known as sinus augmentation, is a form of bone grafting performed in the upper jaw. The procedure gently lifts the membrane of the maxillary sinus and places bone graft material into the space beneath it. Over several months, this graft integrates with your natural bone, increasing both the height and density of the jaw. Once healed, the area is strong enough to hold dental implants securely.
Sinus lifts are often recommended when patients do not have enough bone in the upper back jaw to support implants. This lack of bone may be caused by:
A sinus lift addresses these issues by restoring bone where it is most needed, making dental implants a predictable option for long-term stability.
At Dr. Geoffrey Rubinshtein Periodontics & Implantology, sinus lifts are performed with patient comfort and precision in mind. The procedure usually involves:
There are two primary techniques: the lateral window approach, which accesses the sinus from the side of the jaw, and the crestal approach, performed directly from the implant site. Your periodontist will determine the most appropriate method for your case.
Following the procedure, patients usually return to daily activities within a couple of days. Mild swelling, pressure, or sinus congestion may occur during the first week but generally subsides quickly.
Healing takes several months as the graft material integrates with your natural bone, often between four and nine months. During this period, you’ll attend follow-up appointments to track progress. Once sufficient bone has developed, dental implants can be placed securely.
To protect the graft, patients are advised to avoid nose blowing, heavy lifting, or strenuous activity for a short time after surgery. Detailed care instructions will be provided to support smooth healing.
Sinus lift surgery is considered safe and predictable. However, as with all surgical procedures, there are some risks, including:
If the sinus membrane is perforated, it is usually repaired immediately. In some cases, healing may be required before the graft can be attempted again. Careful planning with advanced imaging helps minimize risks and improve outcomes.
A: No. The procedure is performed under anesthesia. Most patients experience mild soreness afterward, which is typically managed with medication.
A: Initial healing usually takes one to two weeks. Full bone healing takes four to nine months before dental implants can be placed.
A: Dental implants are typically placed four to nine months after surgery, depending on healing and the amount of bone grafting required.
A: Sinus lift surgery has a high success rate, often over 90 percent, when performed by an experienced periodontist.
A: No. A sinus lift is a routine outpatient procedure commonly performed by periodontists and oral surgeons.
A: Bone grafts may come from your own bone, a donor source, an animal source, or synthetic material. Your periodontist will recommend the best option.
A: No. A sinus lift is only needed when there is insufficient bone height in the upper jaw to support implants safely.
A: Risks are uncommon but may include sinus membrane irritation, infection, or delayed healing. Proper planning and imaging help reduce these risks.
A: Most membrane tears can be repaired during the procedure. In some cases, healing time is needed before continuing treatment.
A: In certain cases, short or angled implants may be used. A clinical evaluation is required to determine the safest option.
A: Coverage varies by plan. Some dental or medical insurance policies may cover part of the procedure if it is medically necessary.
A: Costs vary based on complexity and grafting materials. A consultation and imaging are needed to provide an accurate estimate.
