Abstract: An intraoral device (1) with a pair of dental aligners (10), each aligner having an outer shell (100) of rigid plastic in the shape of a rounded V defining branches joined at the front part (10a) of the outer shell. The front part has a truncated part in the form of an elongate notch (104), which confers flexibility on the outer shell in a plane orthogonal to the median sagittal plane of the aligners by bringing together or spacing apart the branches of the V. The outer shell includes an impression (106) formed in the front part on the outer face of the outer shell and extending on either side of the elongate notch. The notch cooperates with an attached wedge (50) which serves as a mechanical abutment for blocking flexion of the outer shell at a given curvature when the attached wedge (50) is fixed in the impression (106).

Abstract: A device for the relative positioning of the lower and upper jaws of a subject that includes splints intended to be disposed on the dental arches of the lower and upper jaws of the subject and linked by link members disposed in an occlusal position, between the splints, each link member includes posterior and anterior end parts made secure and articulated on a respective occlusal face of the upper and lower splints, so as to stress said lower splint in a forward direction. Each link member is composed of a rigid link rod of fixed length whose posterior end part is on the upper splint and in that the position of the posterior end part of each rigid link rod is longitudinally adjustable in the occlusal plane so as to adjust the position of the lower splint.

Abstract: Bite trays (10, 11) having lateral cylindrical pivots (30) articulating two connecting rods (20) in propulsion, the front fastening elements (30a) operate according to a transverse elastic click-lock system and the rear connecting-rod fastening elements (30b) operate according to an open-ring radial locking system, in order to increase the operating safety under all circumstances.
