Dental apparatus for treating malocclusion

Abstract

Device for activating mandibular growth, maxillary growth and mandibular advancement, said device comprising: a first rod (3) with a front end (9) and a rear end (10); a second rod (4) with a front end (11) and a rear end (12); said first (3) and second (4) rods being relatively rigid and having mutually different lengths; a first pivoting articulation (6) for connecting the front end (9) of the first rod (3) to a first dental arch of a person; a second pivoting articulation (8) for connecting the front end of the second rod (4) to the second dental arch of the person; a third pivoting articulation (7) interconnecting the rear ends (10, 12) of the rods (3, 4) and allowing the device to chnage from an open position to a closed position and thus follow the movement of opening and closing of the jaws, characterized in that said third pivoting articulation (7) is able to be connected to the dental arch carrying the shortest rod with the aid of elastic means (5) returning the device to the closed position, in such a way that said rods are able to induce a movement of the mandibular arch relative to the maxillary arch in the closed position of the jaws.

Description

technical field [0001] The present invention relates to the field of orthodontic devices for dental and maxillofacial misalignments, and more particularly to a device for use in orthodontic treatment for repositioning the maxillary arch relative to the mandibular arch, for correcting children and adolescents with class II and class III defects, thereby improving the occlusion of the teeth. The orthotic device according to the invention is intended to achieve correction of mandibular growth, correction of maxillary growth, and nocturnal mandibular advancement for the prevention of sleep apnea. Background technique [0002] Deformation of maxillofacial growth during childhood may result in protrusion or retraction of the upper or lower jaw. This deformation can be corrected by using a device or device called a growth brace, which applies controlled pressure to the mandible and is worn by the child during the maxillofacial growth phase At least for a while.

Problems solved by technology

While such an arrangement would certainly ensure better positioning of each rigid arm, and thus relative to the applied forces of the dental arch, this device still has the disadvantage of maintaining the mouth in an open position, which Uncomfortable and inefficient as known to achieve optimal efficacy with the mouth in the closed position
