An orthodontic assembly articulation device for causing a mandible to move relative to a maxilla includes a lower splint fitted with a lower reinforcement and an upper splint fitted with an upper reinforcement. The reinforcements are connected by a system of rods mounted with sliding capability. A ball joint couples each system of rods with a part of the reinforcements. The ball joint is interdependent with an extension oriented perpendicularly and screwed into a support element interdependent with a corresponding part of the reinforcements. The ball joint engages with the hemispherical cage of an end piece secured to each system of rods. The cage is in communication with an opening of the end piece to allow articulation of the system of rods of about 90° in a vertical plane and about 360° in a horizontal plane, while preventing any swinging of the end piece. |
