A prescription for an orthodontic brace is selected by providing data representing a number of teeth of the dental arch and by displaying images of the teeth in two or more different positions. Images of at least one tooth when in the first position and when in the second position are simultaneously displayed in superimposed fashion, and any difference in orientations of the displayed tooth images between the first position and the second position appears in contrast. As a consequence, the relative difference in positions can be readily observed. The invention is particularly useful for selecting a prescription of a brace from two or more prescriptions, and is also useful for observing the relative effect of a single prescription when used on certain teeth in comparison to the position of the same teeth during an earlier stage of treatment.

An orthodontic brace includes a set of appliances that are connected to respective teeth of the patient. At least some of the appliances include a latch that is operable to release an archwire from the appliance whenever the force exerted by the archwire exceeds a certain value. This value is higher for appliances connected to certain teeth than the value associated with appliances connected to other teeth, in accordance with the particular malocclusion encountered. The brace is constructed to ensure that the goals of the treatment program are carried out in an efficient manner while reducing the likelihood of inadvertent release of the archwire during the course of treatment.

An archwire assembly comprises an archwire with a crimpable sleeve adapted to slidably move along the archwire so as to be positioned between two adjacent brackets of orthodontic braces.
