 note = {application/pdf, It is very important to resolve the imbalance between tooth size and alveolar bone length, that is the dental arch length discrepancy, when we make a treatment plan for an orthodontic patient. This imbalance needs the same amount of space on the dental arch to resolve the arch length discrepancy. Orthodontists usually apply four premolar extraction, dental arch expansion and molar distalization to resolve this problem. As another orthodontic method tooth width reduction to resolve the discrepancy has been developed by Jack Sheridan since 1985. In his report, this method reduced the percentage of the extraction case. The purpose of this study was to present an orthodontic case treated with this method, to introduce how to calculate the width of dental enamel using dental X ray film and how to reduce the enamel, and finally to clarify the importance of clinical usage of this method. As the result, it was possible to calculate correctly the enamel width using dental X ray film and personal computer digital processing methods, and to apply the width for enamel reduction clinically. This enamel reduction method was understood to be an available method for resolving the moderate imbalance of tooth size discrepancy easily and quickly, as well as comparing expansion of dental arch or distalization of molars.},
