Interactive, computer based orthodontist treatment planning, appliance design and appliance manufacturing is described. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. The data from the several frames are registered to each other to provide a complete three-dimensional virtual model of the dentition. Individual tooth objects are obtained from the virtual model. A computer-interactive software program provides for treatment planning, diagnosis and appliance from the virtual tooth models. A desired occlusion for the patient is obtained from the treatment planning software. The virtual model of the desired occlusion and the virtual model of the original dentition provide a base of information for custom manufacture of an orthodontic appliance. A variety of possible appliance and appliance manufacturing systems are contemplated, including customized archwires and customized devices for placement of off-the shelf brackets on the archwires, and removable orthodontic appliances.

An intra-oral camera for producing an axially aligned picture of an intra-oral item of interest permits a rapid taking of pictures, whereby burdensome usage requirements are avoided without, however, suffering any diminishment in the quality of the picture that is taken. A computer-controlled picture taking positioning of the intra-oral camera properly positions the camera for taking pictures of objects of interest. The proper picture taking position of the camera ensures that the picture of an intra-oral object or an area of interest such as, for example, a tooth of a patient, is taken in the desired size, at the desired angle, and at the desired location.

An intra-oral apparatus includes a bracket having a base to secure the bracket to a tooth, the bracket having an appliance attachment, and an electronic module having an attachment point to releasably secure the electronic module to the appliance attachment.
