Description

The invention relates to medicine, namely, orthopedic dentistry, and can be used in planning removable and non-removable orthopedic structures in the study and creation of functional occlusion and other types of treatment.

A device for determining the severity of sagittal transversal occlusal curves is known, including a facial bow, with a holder mounted on it with the ability to move its fixation by means of a clamping screw, rigidly connected at an angle of 90 ° to an adapter, in the hole of which is located with the possibility of axial movement, rotation and fixation by clamping screw is a vertical pin, while the protractor is fixed at the lower end of the pin with the possibility of axial rotation around the fastening screw, and the base of the protractor has an extension in the form of a bar provided at the end with a removable measuring pin. The entire surface of the graduated pin is marked with a scale of 1 mm.

(Patent RU 2218127, IPC А61С 19/04, 2002)

The disadvantage of the known device is that the face bow, with the holder with the clamping screw installed on it, is rigidly connected at an angle of 90 ° to the adapter of the vertical post of the protractor, with the applied markings with a division value of 1 mm does not provide the exact position and correction of the patient's occlusal plane symmetrically to the right and left sides.

The closest technical solution is a device for determining the prosthetic plane of the face, containing a U-shaped occlusal plate with a base, a handle and two lateral index plates, which are monolithically connected to each other and made in the same plane from the same material, with the same thickness. The lateral index plates are connected to the base of the occlusal plate at an angle of 90-170 °. The side indicator plates have tongues bent at 90 ° -170 ° at the ends, which are parallel to each other.

In the occlusal plate with rounded edges in the center along the axial line, a U-shaped cutout 2 mm wide, 32 mm long and twelve through holes with diameters of 3.5 mm each are made. Twelve through holes in the plate allow the positioning of the removable plastic oval plate with the midface indicator by means of positioning pins in three positions depending on the patient's face type and transfer to the articulator for the manufacture of dental restorations. The distance between six holes of 17 mm relative to the centerline of the plate and six other holes are located symmetrically to the left and right sides of the plate at a distance of 22 mm from the centerline for installing a removable plastic oval-shaped plate in one of three positions. At the base of the occlusal plate, two side holes and one central hole are made, in two side holes there are studs with washers connecting the side indicator plates with hinges and a wheel screw with an eyeliner to the Camper horizontal (nasal line from the middle of the ear tragus to the outer edge of the wing of the nose) and register the position of the upper jaw in the patient's skull for the subsequent manufacture of high-quality prostheses. In the central hole there is a bushing with a diameter of 8 mm and a removable indicator of the midline of the face, bent at an angle of 150 ° with plastic tips and face supports in the form of a round disc, fixed in a bushing, in which a hole with a diameter of 4 mm is made with an adjusting and fixing screw on the upper and the lower part allows you to fix the position of the upper jaw in the midline of the face to create aesthetic and functional occlusions.

On the occlusal plate, a removable oval-shaped plastic plate with a mid-face indicator is installed, on the inner surface, installed with four positioning pins, it allows you to fix the position of the upper jaw in the skull and transfer it to the articulator and make high-quality prostheses.
