Overjet vs. Overbite
Before identifying the treatments for these two conditions, it’s worth noting their differences. According to the University of Michigan Health Library, overjet teeth happen when the upper front teeth push outward. This condition is also known as “buck teeth.” To get even more specific, the New South Wales Government defines overjet as a horizontal misalignment between the upper and lower front teeth. When the alignment between these teeth is normal, the upper front teeth sit roughly 2 millimeters in front of the lower teeth. Overjet describes a condition where the horizontal separation is greater than 2 millimeters. This image, courtesy of MedlinePlus, provides an example of what overjet looks like.
Overbite, on the other hand, refers to a vertical misalignment between the upper and lower front teeth. To put in other terms, an overbite, according to the American Association of Orthodontists,is a condition in which the upper front teeth excessively overlap the bottom front teeth when back teeth are closed. It’s also called a “deep bite” or a “closed bite.” Overbites are a reasonably common condition. A review of studies in the Dental Press Journal of Orthodontics revealed the prevalence of overjet and overbite in the global population. Approximately 20 percent of individuals studied, including children and adults in the U.S., the U.K., India, China, and several countries in Africa and Europe, exhibited an overjet. Approximately 22 percent had an overbite.
