Abstract
Vertical dimension can be described best as the vertical height of the face. It is determined by muscular relationships, utilizing the physiologic rest position of the mandible as the guiding factor. Therefore, a practical knowledge of the physiologic rest position is essential in the determination of correct vertical dimension of occlusion.Vertical dimension of occlusion is not usually a major concern in routine fixed porosthodontic treatment. Patients with severe tooth wear, however, may require extensive restorative treatment to regain appropriate function, esthetics and comfort. Treatment of a reduced vertical dimension is not designed to increase the vertical dimension beyond normal, but is intended to restore the amount of vertical dimension that has been lost. In rehabilitative procedures, the masticatory organ must be reconstructed within the limits of the physiologic rest position with sufficient allowance for a functional interocclusal distance. Management of a case of severe tooth wear caused by loss of posterior tooth support is described.
