摘要：
A virtual model of a dental patient's dentition is provided by obtaining a digital data file of the patient's teeth and orthodontic appliances connected to the teeth, and then combining data from the data file with other data that represents surfaces of the teeth underlying the appliances. The virtual model is useful in preparing a physical model of the patient's current dentition that can be used, for example, to make a dental retainer. Advantageously, the retainer can be fabricated before the orthodontic appliances are disconnected from the patient's teeth and ready for use as soon as the patient's teeth have reached their desired positions in the oral cavity.
