Abstract: The amount of anterior tooth display, which is one of the most important esthetic parameters in anterior zone, has become a significant reference for prosthodontic and orthodontic treatment. Clinical research shows that the maxillary incisor display at rest and during smile is about 2-4 mm and 8-10 mm respectively. With the increasing age, maxillary anterior tooth display gradually decreases while mandibular anterior tooth display increases. Also, the anterior tooth display is affected by sex and lip length. Meanwhile, there is no uniform standard for the preference of anterior tooth display. Hence, it is essential to take patients’ esthetic demands and their own oral conditions into full consideration when making treatment plans.
