What is a Sinus Lift?
The maxillary sinuses are behind your cheeks and on top of the upper teeth. These sinuses are empty, air-filled spaces. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.
The key to a successful and long-lasting dental implant is the quality and quantity of jawbone to which the implant will be attached. If bone loss has occurred due to injury or periodontal disease, a sinus augmentation can raise the sinus floor and allow for new bone formation. A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw. The procedure seeks to grow bone in the floor of the maxillary sinus above the bony ridge of the gum line that anchors the teeth in the upper jaw. This enables dental implants to be placed and secured in the new bone growth.
How is the Procedure Accomplished?
Most commonly, a small incision is made on the premolar or molar region to expose the jawbone. A small opening is cut into the bone, and the membrane lining the sinus is pushed upward. The underlying space is filled with bone grafting material, either from your own body or from a other sources. Sometimes, synthetic materials that imitate bone formation are used. After the bone is implanted, the incision is sutured and the healing process begins. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in the newly formed sinus bone.
If enough bone between the upper jaw ridge and the bottom of the sinus is available to sufficiently stabilize the implant, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for up to several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
The sinus graft makes it possible for many patients to have dental implants that previously had no other option besides wearing loose dentures.
A sinus augmentation is generally performed at Dr. Skigen’s office, under local anesthesia. Some patients may request oral or intravenous sedative medication as well.
Am I a Candidate for a Sinus Lift Procedure?
A sinus lift may be necessary if you:
-
are missing more than one tooth in the back of your jaw
-
are missing a significant amount of bone in the back of your jaw
-
are missing teeth due to a birth defect or condition
-
are missing most of the maxillary teeth and require support for dental implants
-
How Many Implants Do I Need?Most frequently, one implant per missing tooth is placed. Because many of the larger teeth in the back of your jaws have two or three roots, the most common approach is to replace missing back teeth with larger implants.
-
What will I use for teeth while the Implants heal?Many options are available, and they are tailored to your specific requirements. If you need a replacement tooth while the implants are healing, temporary removable teeth or a temporary bridge can be made. If all of your teeth are missing, we can usually modify your present complete denture or make you a new temporary denture. If you would prefer non-removable teeth during the healing phase, temporary transitional implants usually can be placed along with the permanent implants, and temporary teeth may be made and inserted the same day. Depending on your particular situation, some implants can be placed and “loaded” immediately. This means a temporary or permanent replacement tooth can be placed on, or shortly after, the day the implant is placed.
-
What are the potential problems with Implants?Although it is natural to be concerned about the pain that may be caused by these procedures, most patients do not experience severe or significant post-operative pain. Pain medication and antibiotics will be prescribed for you to make your recovery as easy as possible. Occasionally, some people develop post-operative infections that require additional antibiotic treatment. Even though great care is taken to place the implant precisely, occasionally adjacent teeth are injured in the placement process. In addition, there is a chance that the nerve in the lower jaw, which provides sensation to your lower lip and chin, may be affected. If you are missing quite a lot of bone, it might be difficult to place an implant without infringing on the nerve space. Although we take great care to avoid this nerve, occasionally it is irritated during the procedure, resulting in tingling, numbness or a complete lack of sensation in your lip, chin or tongue. Usually these altered sensations will resolve within time, but they can be permanent and/or painful. If you notify us of post-operative numbness as soon as possible, it will allow us to manage your care in the most appropriate way.
-
How long will Implants last?Implants usually last a long time. When patients are missing all of their teeth, long-term studies (more than 30 years) show an 80 to 90 percent success rate. For patients missing one or several teeth, recent studies show a success rate of greater than 95 percent, which compares favorably with other areas in the body that receive implant replacement (such as hips or knees). However, if one of your dental implants either doesn’t heal properly or loosens after a period of time, you may need to have it removed. After the site heals (or on occasion at the time of removal), another implant usually can be placed.
-
When are the replacement teeth attached to the Implant?The replacement teeth are usually attached to the implant when adequate healing has occurred and your jawbone is firmly fused to the implant. Depending on a variety of factors, it may be possible to begin this phase of your treatment immediately or shortly after implant placement. We will review the most appropriate treatment sequence and timing for your particular situation. The dental work required to complete your treatment is complex. Most of the work involves actually making the new teeth before they are placed. Your appointments are considered more comfortable and more pleasant than previous methods of tooth replacement. Frequently, this process can be performed without local anesthesia. Your restorative treatment begins with specialized impressions that allow us to produce a replica of your mouth and implants. We will also make “bite” records so that we see the relationship of your upper and lower jaws. With this information, we will make the abutments (support posts) that attach your replacement teeth to your implants. Various types of abutments exist. Frequently, we can use “off the shelf” abutments. Other times, custom abutments must be made of gold or a tooth-colored ceramic material. As you can imagine, these custom made abutments add to the cost and treatment time involved. Which abutment to use is a decision that often cannot be made until after healing is complete and impressions have been made.
-
How do I clean my Implants?As with natural teeth, it is important that you clean implant-supported restorations regularly with toothbrushes, floss and any other recommended aids. You should also visit your dentist several times each year for hygiene and maintenance. As with regular dentures and other tooth replacements, your implants and their associated components are subject to wear and tear and eventually will need repair, including clip replacement, relines, screw tightening, and other adjustments.
-
Will one Doctor do the entire Implant procedure?Usually, a dental surgeon places the implant(s) and performs other necessary surgical procedures – your general dentist provides the temporary and permanent replacement teeth. Both doctors are involved in planning your dental treatment. Also, depending upon a variety of factors, different dental specialists may help with your dental care.
-
How much do Implants cost?Before treatment begins, every effort will be made to give you an accurate estimate of all the expenses involved in placing the implants and making your replacement teeth. In many cases, there is an initial charge for the diagnostic work-up, including study models, x-rays, and the fabrication of a surgical template to ensure the best possible result. In addition you will be charged for the abutment or support post(s), plus the crown, dentures, or anything else that will be placed over the implants, including temporary restorations. Periodic maintenance such as hygiene visits, tissue conditioners, denture relines and other repairs will also incur additional charges. When different doctors are involved in your treatment, you will be charged separately for their services. We will try to assist you in estimating what your actual payments will be after we evaluate your insurance coverage or other third party payments. Also, you should consider your personal financial investment in each treatment option as some insurance companies provide limited or no coverage. Each patient is unique, and it is not possible for us to discuss every option and every contingency for treatment outcome. This booklet is intended to help you understand the general treatment options available to you. If your specific treatment options are not clear, please contact us. We will be happy to answer any questions you have about your dental care.

Why select Dental Implants over more traditional types of restorations?There are several reasons: A dental bridge can sacrifice the structure of surrounding good teeth to bridge the space of the missing tooth/teeth. In addition, removing a denture or a “partial” at night may be inconvenient, not to mention dentures that slip can be uncomfortable and rather embarrassing.
