Although physiologic abrasion in normal range need not to be corrected, when hard tissue of teeth are worn abnormally fast, it can cause severe damage and destroy esthetics and, functional structure of occlusion consequently. To establish a correct occlusal plane and space for the patient with worn dentition, it is necessary to increase vertical dimension. However, actual occlusal vertical dimension remains unhanged with compensation for the increase of alveolar bone height equivalent to the decrease of teeth length. A 74-year-old male presented with worn dentition and fractured tooth. Based on the assessment of OVD including clinical findings, full-mouth rehabilitation without increase of OVD was planned. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition without changing occlusal vertical dimension. (J Korean Acad Prosthodont 2016;54:160-6)
