An acoustically investigated case of phonetic change in higher vertical dimension.
This report presents the phonetic changes of a patient whose occlusal vertical dimension is extended. His chief complaint is esthetic restoration of his anterior teeth, but his occlusal vertical dimension is abnormally shortened by long-time attrition. Therefore we extended his occlusal vertical dimension, and reconstructed his occlusion, and carried out acoustic observations.
