"Bitejumpers", also known as "Forsus Springs", are a type of class II bite corrector. A class II bite is commonly known as an "overbite", or "overjet", and describes a bite where the upper teeth are positioned too far forward compared to the lower teeth. In many cases this makes a "bucked tooth" look, where the upper front teeth stick out. Bitejumpers are used to correct this type of bite.
Bitejumpers are springs that connect to the braces from the upper back teeth to the lower front teeth. Since they are connected to the braces they do not need to be removed or replaced by the patient, and instead remain in place until they are removed by us. They are designed to move freely, allowing the patient to talk and chew normally, and are almost completely hidden from view. This is a huge improvement from the traditional headgear, which is unsightly and requires the patient to put it on and take it off themselves.
The typical treatment with Bitejumpers starts with the placement of a full set of braces, including bands on the molars. Bitejumpers are usually placed after six to nine months and take about six to nine months to complete their portion of the bite correction. Because we always expect a small amount of relapse after removing the Bitejumpers, we typically overcorrect the overbite before removing them. This means that a patient may develop an underbite (where the lower teeth stick out further than the upper teeth) just before the Bitejumpers are removed. This underbite is not permanent and is completely normal for patients in Bitejumpers. After the Bitejumpers are removed it is not uncommon to then go through a period of elastic wear, where patients are asked to wear rubber bands between the upper and lower braces.
Because the Bitejumpers are mobile and adjustable, they may come apart when a patient opens their mouth wide, as when yawning. There are two major parts of the Bitejumpers, the spring (attached to the upper molars) and the arm (attached to the lower wire). When opening the mouth really wide the arm may come out of the spring. The arm can be replaced by openening wide, compressing the spring and fitting the arm back into the spring. If you have a Bitejumper that has come apart and are having trouble getting it back together please call our office for assistance.
