Gradual tooth wear is a natural process of aging, but pathological wear over physiologic ranges leads to functional and esthetic problems. The loss of posterior support may cause pathological wear of anterior teeth, which results in reduction of vertical dimension and disharmony of occlusal plane. To solve this problem, determination of proper vertical dimension considering centric relation is necessary. This case report presented 71-year-old male, who had the severe wear of lower anterior teeth due to loss of posterior support. By meticulous evaluation, a full mouth rehabilitation with elevation of vertical dimension was planned. After 8 months of follow-up, stable occlusal scheme is maintained and patient was satisfied with clinical outcome functionally and esthetically. [ABSTRACT FROM AUTHOR]
