Orthognathic surgery is needed when the top and bottom jaws don't meet correctly and/or teeth don't adequately fit within the jaw. Teeth are straightened with orthodontics, and corrective jaw surgery repositions a misaligned jaw. This not only improves facial appearance, but also ensures that teeth meet correctly and function properly. People who can benefit from orthognathic surgery include those with an improper bite, or jaws that are positioned incorrectly. Jaw growth is a gradual process and in some instances, the upper and lower jaws may grow at different rates.
Although most people develop and grow 32 permanent adult teeth, many times their jaws are too small to accommodate the four wisdom teeth. When inadequate space prevents the teeth from erupting they are called impacted wisdom teeth. This indicates their inability to erupt into the proper position for chewing and cleaning.
TMJ (temporomandibular joint) disorders are a family of problems related to your jaw joint. If you have had symptoms like pain or a "clicking" sound, you'll be glad to know that these problems are more easily diagnosed and treated than they were in the past. These symptoms occur when the joints of the jaw and the chewing muscles do not work together correctly.
A natural tooth consists of a root and a crown. If you compare natural teeth to implant-supported replacement teeth, you’ll see they have the same basic parts. Both have a crown (the visible part used to chew food). Both have a root that holds the tooth securely under the gum and is anchored into the jaw. The difference is that the implant is made of titanium – the same time-tested material used by surgeons for artificial joints. When you lose a tooth, you lose both the root and the crown.
