b. Deep bite: Simply means that the upper front teeth close too far over the lower front teeth. More precisely a wide range of incisal overlap is seen with normal posterior occlusal relations. Depth of bite becomes a defined clinical problem when occlusal or temporomandibular function is, or may become, impaired and when facial aesthetics is harmed. The depth of bite must be related to the health of the soft and supporting structures, temporomandibular function, and the effects of future skeletal growth on these factors. Incisors may seem to have normal overbite, but their correction by simple tipping may produce a deeper bite. Therefore a deep bite as a clinical problem is not defined in terms of millimeters seen today but in the light of
