What is the ideal overbite for Class I Division I occlusion?

In Class I Division I occlusion, the ideal overbite is indeed around 50%. This represents the vertical overlap of the upper incisors over the lower incisors, which is considered optimal for functional and aesthetic purposes. A 50% overbite usually allows for proper alignment of the teeth, effective occlusal function, and a harmonious appearance of the smile. It provides sufficient coverage to protect the anterior teeth while facilitating proper bite and jaw function.

This ideal also takes into account the relationship between the upper and lower arches and their alignment, which is essential for effective chewing and minimizing wear on the teeth. While individual variations can occur, maintaining an overbite around this percentage helps in achieving overall dental health and stability in occlusion for individuals with Class I Division I characteristics.
