Space analysis and Bolton's analysis are two important parts of the orthodontic diagnostic and treatment planning procedures for malocclusions. Measuring data from plaster models with boley gauge or vernier caliper is a traditional method. Due to recent technologic advance, the models are allowed to be digitized and measured with software tools. The purpose of this study was to compare the differences between measurements done by software tools on digital models and those done directly on plaster models.
