ZERO-POINT CONTROLLER Russian patent published in 2019 - IPC A61C11/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to dentistry, and is intended for use in dental treatment in case of abnormal bite, edentulous jaw, oligodontium. Zero torque controller comprises a bearing frame, a transverse frame, a face arc, mounting elements for the face arc, a mouthpiece, a fixing part for fastening the face arc on the mounting elements for the face arc at a given installation angle, headphones fixed on adjusting elements for headphones, control point indicator for indication of bite occlusion concentration segment. Supporting frame with left and right side frames is configured to be placed on both sides of patient's head. Crosswise frame interconnects left and right side frames. Mounting elements for face arc are fixed to side frames. Face arc is made with possibility of installation on mounting elements for front arc with possibility of disconnection. Mouthpiece is configured to be fixed on the face arc and is intended for insertion into the oral cavity of the patient. Fixing part for fastening of face arc on mounting elements for face arc at specified angle of installation is made with possibility of connection to mounting element for front arc with possibility of disconnection. Headphone setting elements are installed on side frames. Headphones are fixed on adjusting elements for earphones. Covering element for support of bearing frame is arranged in area between eyebrows of patient and is located in central part of crosswise frame. Reference point for indicating an occlusal force concentration segment is set in the region of the patient's nasal area and is located in the central part of the transverse frame. Mouthpiece is made in the form of a curvilinear surface located along a spherical occlusal surface, the center of which is a point on an occlusion line passing through a segment of concentration of occlusion force and parallel to side frames, and a preset angle of installation is selected so that the mouthpiece is positioned on a curvilinear occlusal surface inside the oral cavity.

EFFECT: invention enables quantitative reconstruction of the ideal occlusion inherent in each patient.
