In the occlusal plane, if the mandibular incisors are located above the line, this indicates a:

The occlusal plane is an important reference in orthodontics and dentistry, as it helps to evaluate the relationship between the upper and lower teeth during occlusion. When mandibular incisors are located above the occlusal plane, it suggests that the vertical overlap of the incisors is greater than normal. This condition is described as a deep bite.

A deep bite occurs when the upper front teeth significantly overlap the lower front teeth when the jaws are closed. This excessive overlap might impair function and can lead to other dental issues over time. The position of the mandibular incisors above the occlusal plane indicates that the bite mechanics might not be balanced, leading to the deep bite phenomenon.

Other concepts like crossbite, open bite, and overjet refer to different malocclusions that do not specifically align with the description of mandibular incisors being above the occlusal plane. In a crossbite, the relationship is more about the positioning of the teeth mesiodistally. An open bite describes a lack of vertical overlap, while overjet pertains to the horizontal distance between the upper and lower incisors. Each of these conditions is distinct from a deep bite, which is clearly indicated by the position of the mandibular incisors relative to the
