Jaw opening and closing relies both on mandibular and head movements. Jaw and neck muscles are jointly activated in jaw functions. Restricted head-neck mobility can impair jaw function. Recent studies show that head fixation due to neck injury leads to reduced manibular movement and shorter duration of jaw-opening/closing cycles. Considering this relationship it is important that during different cosmetic dental procedures the occlusion or bite be evaluated as well as the position of the neck. Venetian Veneer procedure is a porcelain veneering procedures developed at the International Institute of Cosmetic Dentistry to address the issue of occlusion.
