Patent ID: 7771196

Claim:
An orthodontic appliance for distalizing opposed molars of an upper jaw of a patient, comprising: a) a bracing plate, which in its intended use, rests on a palate of the patient, and which can be secured, via wire elements disposed on the bracing plate, to opposed teeth that are located anteriorly of molars to be distalized; b) two force modules on a posterior end of the bracing plate, spaced laterally apart from one another and adjustable independently of one another, connected to the bracing plate, each force module being connectable via a respective elastic spring arm to one of the two molars to be distalized; c) each of the respective force modules including a threaded rod that can be screwed into and unscrewed from the bracing plate and also including a connecting part, which is axially displaceable with the threaded rod but secured from rotation and which extends perpendicular to a longitudinal axis of the threaded rod, and d) a rodlike guide element extending parallel to the threaded rod secured to the connecting part and on one end displaceably engaging a guide recess in the bracing plate and on another end is connected to an end region of the elastic spring arm associated with the respective force module; wherein the rodlike guide element is a tube; and the end region of the elastic spring arm protrudes into a tubular interior of the rodlike guide element and is constructed and arranged to move with the rodlike guide element.
