An orthodontic retainer system including retainer modules that are applied to adjacent teeth in a patients mouth, and a method and apparatus for delivering the system. The retainer modules (114) may be provided in the form of mutually attracted members, such as magnets, that are temporary coupled on opposites sides of a delivery member (112) for positioning and bonding to an adjacent pair of teeth. In one exemplary embodiment, the retainer modules have rounded and/or chamfered edges and sloped and curved lingual surfaces, and may include a magnet that is received and sealed within an enclosure or cover that has the same shape or profile as the magnet and is made of a wear-resistant biocompatible material. In one exemplary embodiment, the delivery member (112) is substantially L-shaped, which advantageously allows an orthodontist to enter only a small portion of the patients oral cavity to position the retainer modules on a patients teeth, and eases the orthodontists delivery of the retainer modules by substantially eliminating the need for the orthodontist to manipulate or otherwise move the patients lips, tongue, and/or cheeks. The delivery member may also include pusher elements that contact the retainer modules for exerting a force against the modules to press same firmly against the teeth in order to enhance bonding between the modules and the teeth.
