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.

The stop may include removable stops where the sleeve is movable along the archwire between the stops. The removable stops may be movable along the archwire with the application of a sufficient force. The stop may also include a friction-creating substance applied to either the sleeve or the archwire such that it takes a sufficient force to move the sleeve along the archwire. The stop may also include a partially crimped sleeve applied to the archwire such that it takes a sufficient force to move the sleeve along the archwire.

A method of oral treatment comprises passing a flow of a gas mixture from a pressure vessel containing the gas mixture through a generator of non-thermal plasma; applying a partially ionising electrical potential to the flow of the gas mixture in the plasma generator, and thereby forming a non-thermal gaseous plasma in the gas mixture, and causing the flow of the gas mixture downstream of the plasma generator to perform the oral treatment. The gas mixture comprises (a) a noble gas selected from helium and argon and mixtures thereof, and (b) an additive gas selected from water vapour, air, oxygen, nitrogen, hydrogen, carbon monoxide, carbon dioxide, nitrous oxide and nitric oxide and mixtures of any two or more thereof. The additive gas forms up to 1% by volume of the gas mixture. The oral treatment may be the cosmetic whitening of teeth, the non-clinical cleaning of teeth or the in situ cleaning of orthodontic braces, amongst others.
