Why use it?
One of the most common concerns orthodontists treat is the discrepancy that occurs when the upper teeth protrude beyond the lower. Ordinarily when we see a patient with the upper teeth protruding, we tend to think that the upper jaw and teeth are too far forward: but more often than not, this condition is due to a small lower jaw that is further back than it should be. With these patients, we would like to encourage the lower jaw to catch up in growth, and braces with the AdvaSync appliance help this happen.
What is it?
The AdvanSync (Made by Ormco) appliance is a non-removable appliance that is used in adolescents that have a small or posteriorly positioned lower jaw. The appliance is used to encourage the lower jaw to come forward during the adolescent growth spurt as well as providing dental changes to move the lower teeth forward. It is cemented to the upper and lower molars, connecting the jaws together in a way that keeps the lower jaw in a more forward position. The AdvanSync needs to be in place for 6-9 months if skeletal jaw changes are desired. In all cases, braces are placed on the teeth at the same time as the AdvanSync, allowing us to treat patients more efficiently and thus limiting the total treatment time in braces

Unlike headgear the AdvanSync is hidden inside the back of the mouth and is virtually unnoticeable. Unlike similar appliances (such as the Herbst appliance and Forsus appliance), the AdvanSync is half the size of theses for maximum patient comfort and range of motion. It can be seen when a patient opens their mouth wide, but it does not come out of the mouth. In many patients, the AdvanSync immediately improves their appearance from a profile (side) view, in that it moves the lower jaw (and therefore the chin) forward.
Will it be uncomfortable?
The first two weeks with AdvancSync in place is challenging for the patient. It is something that takes time getting used to. Patients will not feel discomfort, but rather have to adjust to the appliance and the new position of their jaws. The feeling is similar to what is felt when one moves their lower jaw forward so that the edges of the bottom front teeth hit the edges of the top
front teeth. Patients can eat normally with the AdvancSync in place.
