FAQs About This New and Miraculous Procedure
How can sinus surgery contribute to the replacement of missing back teeth with dental implants?
Dental implants must be anchored the in bone to be successful. Maxillary sinus surgery can help regenerate bone that has been lost and is critically needed to anchor dental implants.
What are the maxillary air sinuses?
Inside the upper jaw, or “maxilla,” are structures known as the maxillary air sinuses, one on either side of the upper jaw. Each sinus is an air-filled space lined by a membrane. Upper back teeth are normally encased in the bone of the maxilla, below the sinuses.
Why is it important to replace missing back teeth?
Replacing back teeth restores the ability to eat, chew, and talk properly. The back teeth also provide facial and cheek support.
Why use dental implants?
Dental implants are the state-of-the-art method for replacing missing teeth.
Why does bone loss occur?
Unless special precautions are taken to prevent it, when teeth are lost, the bone supporting them is also lost.
If there is insufficient bone to anchor dental implants, what are the alternatives?
If all the back teeth are lost and dental implants cannot be placed, removable upper dentures may be the only alternative.
How do you determine whether a sinus surgical procedure is necessary?
The size, shape, and remaining bone of the maxillary sinuses influence whether you can have dental implants with or without a sinus surgical procedure.
How does surgery grow bone?
A small window is created in the sinus wall above where implants need to be placed. The sinus membrane is lifted and the space thus created filled with bone grafting and biologically active bone generating materials. The window is then closed and simply heals.
How is the surgery done?
The surgical procedures are performed from inside the mouth in the area just above the missing back teeth. They are generally carried out under local anesthesia (small shots, just like for a filling), sometimes with the addition of sedation or anti-anxiety medication.
How do bone grafts work?
Bone grafts act as scaffolds that the body replaces with its own bone. The most well researched bone substitute grafting material is currently bovine (cow) bone. All grafting materials are approved by the Food and Drug Administration. They are specially treated to render them completely sterile, non-contagious, and free of rejection factors.
What can I expect after surgery?
Moderate swelling and discomfort after surgery generally lasts for a few days to a week, about the same as having an upper impacted wisdom tooth removed. Supportive treatment usually includes a course of antibiotics to prevent infection and prescription strength medication of the aspirin or ibuprofen type. A decongestant may also be prescribed, if necessary. Healing is generally uneventful.
Who performs this surgery?
Maxillary sinus augmentations are usually carried out by oral surgeons, periodontists, or appropriately trained general dentists. Proper assessment of your situation and diagnosis are critical pre-requisites to the right procedure.

Dental implants traditionally have a high success rate with numerous studies showing long-term success rates of over 95%. This is just one of the reasons they have been widely accepted as the best method for permanently replacing missing teeth. In fact, over-dentures, which are full dentures supported and stabilized by at least two dental implants, are now considered the standard of care by the American Dental Association (ADA) for people who have lost all of their teeth in one or both jaws. And while they have a high success rate, there are some factors that can compromise the success rates of implants.
These factors are generally divided into three categories: general health concerns, local factors, and maintenance issues.
- General health concerns: Your general health, lifestyle, and habits can play a major role in the success of dental implants. For example, smoking, diabetes, osteoporosis (porous bone) or a compromised immune (resistance) system can all negatively impact implant healing and success. And if you have a history of radiation treatment to your jawbones, you are at a higher risk for complications.
- Local factors: Some examples of local factors that can affect implant success include bone quality and quantity — having sufficient bone in the right place to accurately secure and locate the implants.
- Maintenance issues: While implants are excellent high tech replacements for missing permanent teeth, they do require routine maintenance. This includes daily cleaning and continued professional care. Otherwise, implants are just like any other technically sophisticated devices — they may be susceptible to breakdown.
Dentists often recommend bone grafting to ensure the success of dental implants. And it is likewise common for people to squirm a bit at the thought. Bone graft? That sounds serious. And maybe a bit, well, unappealing. These feelings are completely understandable. After all, this may be something you've never had to consider before. But there's no reason to worry. HereÃ¢Â€Â™s why:
- Bone grafting is not new or experimental. It is actually a very routine part of the implant process, as well as other types of oral and periodontal surgery. And it is very successful when performed by an experienced doctor.
- Bone grafting materials are processed for safety. The grafts used — whether synthetic or from a natural source, such as cow or human bone — have been specially treated for medical use.
- Only a small amount of this bone-grafting material is needed. Once placed in the site of the missing tooth, it serves as a helpful scaffold your body uses to build more of its own bone in that spot.
- Your implant will be more ideally positioned and may work better. It needs a good, strong foundation with which to fuse. But when teeth are lost, this supporting bone is often lost, too. This loss is often unpredictable and bone grafting limits the change that occurs. In fact that's one of the main benefits of replacing missing teeth with implants: they help prevent bone loss just as a natural tooth does.
- Your implant will look so much better! Think about it: Your original tooth was supported to a certain height by the underlying bone. If that bone is now gone, the replacement tooth is going to be much longer because of the missing bone height. It may not look quite right without that additional support.
So if you want the best-looking and best-functioning implant possible, have no fear of bone grafting. And please contact us to discuss any of your concerns, or schedule an appointment for an implant consultation.

Your son just crashed his skateboard and cracked a tooth, or maybe your daughter fell off the monkey bars at school and now has a chipped front tooth. For children, and some adults, repairing chipped or damaged teeth with tooth-colored restorative materials directly bonded to the teeth may be the perfect solution to restore their smiles.
What is Involved: Composite bonding is a technique that has been developed to correct chipped teeth and other minor dental imperfections. It may also be used to correct mild crookedness or gaps between teeth. The procedure requires the application of a tooth-colored composite resin material to the surfaces of teeth, which is then sculpted to the desired shape. It can be performed in a single visit for one or multiple teeth. The procedure usually takes between one and two hours, and the end result is a beautiful, natural-looking smile.
Advantages for Kids and Adults: Composite resin bonding is a good choice for kids and teens since their jaws are still growing and developing, and they may still be engaged in high-risk activities. After your child's teeth and jaws are fully developed, we can discuss options for more permanent restorations such as porcelain veneers or crowns. These require removal of more tooth structure, which could compromise the long-term health of your child's teeth if done too soon. Composite resin restorations, which bond straight to the teeth and require little to no tooth preparation or drilling are therefore a good option for fixing chipped teeth, and they're less expensive than choosing veneers.
Disadvantages: The longevity of composite resin restorations is related to how well you maintain your teeth. Many people can go for ten or fifteen years before they need to have the bonded resins repaired or replaced. Others will tend to stain and wear after only one or two years and will need some touch-up work.
