Dental implants are a popular and effective restoration for lost teeth, if there’s enough bone present to support the implant. That might not be the case, however, because without the stimulation of the lost tooth, the bone may dissolve (resorb) over time. It’s possible, however, that you may need to re-grow bone in the back area of the upper jaw where your upper (maxillary) sinus is located.
Sinuses are air space cavities located throughout the skull. This feature allows your head to be light enough to be supported by your neck muscles. Inside each sinus is a membrane that lines your sinus cavities, nasal passages and other spaces. The maxillary sinus is located on each side of the face just below the eyes. Pyramidal in shape, the floor of the pyramid lies just above the upper back teeth.
A surgeon approaches the sinus through the mouth, with the objective of moving the sinus membrane up from the floor of the sinus. This is accomplished by placing bone-grafting material in the area. Over time the body uses the grafting material as a scaffold to produce new bone that then replaces the grafting material. The resulting new bone becomes the support for the implant.
If enough bone exists to stabilize an implant but not anchor it, then the surgeon can approach the sinus from the same opening that’s used for the intended implant site, insert the grafting material, and install the implant during the same procedure. If not, the surgeon creates a small “window” laterally over the teeth to access the sinus and insert the graft. The implant is installed a few months later after the new bone is created.
The procedure usually requires only a local anesthetic, although some patients may require additional sedation or anti-anxiety medication. After the surgery, you normally experience mild to moderate swelling and discomfort, about the same as having a tooth removed. All these symptoms can be managed with non-steroidal, anti-inflammatory pain medication and a decongestant for minor congestion in the sinus. We might also prescribe an antibiotic to help prevent infection.
Although this procedure adds another step and possibly more waiting time to implantation, it gives you an option you wouldn’t otherwise have — a life-like, effective replacement of your back teeth with dental implants.

They work hard, and put in lots of time on the field and at home. They learn the rules of the game — as well as the unwritten rules of sportsmanship and teamwork. They receive the proper training, and wear appropriate protective equipment. But sometimes, in spite of everything, kids who participate in sports can be subject to injury. Fortunately, in today's dentistry there are a variety of treatments, as well as preventive measures, which can help.
When faced with serious dental injury, time is of the essence in saving teeth. So, don't delay — come in to see us immediately! If treated promptly, it's possible for teeth which have been dislodged — or even knocked out of the mouth — to be put back in position and stabilized. Afterwards, follow-up treatment will ensure that the tooth has the best chance of recovery.
The treatment of kids' dental injuries is sometimes different than that of adults. For example, in adults, a root canal would generally be necessary, followed by a tooth restoration (crown). But some kids may not need this treatment, since their teeth are still developing. Also, replacing a missing primary (baby) tooth may not be recommended, since it may hinder development of the permanent teeth. Based on his or her individual circumstances, we can develop an appropriate treatment plan for your child.
Luckily, the most common dental injuries aren't nearly as serious — they typically involve chipped or cracked teeth. Most can be repaired by reattaching the broken piece, or using a tooth-colored restoration. If a large part of the structure of a permanent tooth is missing, a crown or “cap” may be placed on the visible part, above the gum line. Smaller chips, even in primary teeth, can be successfully repaired by cosmetic bonding with composite resin materials.
Finally, if your child is involved in athletic activities — or if you are — consider obtaining a custom-made mouthguard. Numerous studies have shown that this protective gear can help prevent many dental injuries. Unlike the off-the-shelf types found in some sporting-goods stores, the ones we provide are individually fabricated from an exact model of the teeth. They're strong, fit comfortably, and offer superior protection at a reasonable cost.
