Description

The technical field to which the invention relates.

The invention relates to medicine, in particular to klammerny systems, for partial dentures with a single tooth and can be used in prosthetic dentistry for partial lamellar and byugelny prostheses.

The level of technology

Known klammernaya system for partial plate and clasp dentures, containing, the basis on which the artificial crown of the teeth, the clasp, consisting of a seat for the prosthesis on the clamer, shoulder and seat of the clamer in the socket (see EI Gavrilov, I. M. Alshits "Orthopedic Dentistry", Medicine, Moscow, 1979, p. 206).

The disadvantage of this klammernoy system is that the clasp with the prosthesis is connected to the basis of the prosthesis, and this connection in the area of the front teeth, especially the upper ones, is not aesthetically pleasing, as can be seen on the teeth.

A known method of manufacturing a partial denture on the upper and lower jaws with a single tooth, which includes the manufacture of an artificial crown on the remaining tooth (sometimes without an artificial crown), the manufacture of a partial denture with clamer fixation on the tooth, while a partial denture is made in compliance with all known clinical and laboratory stages (see VN Kopeikin, LM Demner, "Dental Technique". - M., Medicine, 1985. - S. 206-231).

The disadvantage of this method is that the clamer fixation does not always ensure a good fixation of the removable denture with a single tooth.

A known method of manufacturing a partial denture with a single tooth, including the manufacture of an artificial crown on a tooth, taking an impression from the jaw, making a base with a biting roller, determining the central occlusion, making a metal clasp for the tooth, setting artificial teeth, fitting the wax design of the prosthesis in the mouth. patient, replacing the wax base with plastic, grinding and polishing a removable denture, imposing a finished denture on the jaw, while standing alone b a patient is made an artificial crown with two patrits on its approximate surfaces, an individually manufactured metal frame consisting of a metal reinforcing mesh and a metal element with matrices for accommodating patrons of an artificial crown is welded into the plastic base of the partial denture (see pat. RU No. 2352287 , IPC А61С 13/00, published on April 20, 2009).

The disadvantage of this method is that the clamp fixation does not always ensure good fixation of the removable denture with a single tooth, the base often breaks in the single tooth, as this is the weakest point.

The closest to the technical essence and the achieved positive effect and adopted by the authors for the prototype is a clamping system for fixing a partial denture with a single tooth, consisting of a base with artificial teeth and a clasp, while at one end of the clasper there is a mechanical device consisting of an internal and the outer matrix, made in the form of a hinge, and at the second end - the seat of the klammer in a fixed nest on the artificial crown of the tooth, with the outer closure matrix captivity in the basis of the prosthesis removably together with a prosthesis, and an inner patrix made spherical and is connected to the shoulder clasp, the clasp seat in sockets formed on the artificial tooth crown vertically or horizontally from the lingual or palatal or approximal surface.

In the clamp system, the system is mounted on a plate prosthesis.

In the klammernoy system, the outer matrix is fixed in the saddle-shaped part of the clasp prosthesis (see US Pat. RU No. 2538641, IPC A61C 13/00, A61C 13/265, A61C 13/267, publ. 10.01.2015).

The disadvantage of this klammernoy system is that the clasp with the prosthesis is connected to the basis of the prosthesis, and this connection in the area of the anterior teeth, especially the upper ones, is not aesthetically pleasing, as seen on the teeth, and the clasp has a negative effect on the periodontal tooth.

DISCLOSURE OF THE INVENTION The object of the present invention is to develop a klammernoy system for a partial denture with a single tooth that has a stable fixation, increased chewing efficiency, aesthetics and the elimination of the negative effect on the periodontal tooth, due to the soft transfer of the load on the tooth through the shoulder, made in the form of constantly springing the device and the location of the klammer on the lingual, or palatine, tooth surface, with the possibility of removal.

The technical result, which can be obtained using the present invention, is reduced to a stable fixation of the clamping system, with the possibility of removal, increased chewing efficiency, aesthetics and the elimination of negative action on the periodontal tooth.

The technical result is achieved with the help of a klammer system for a partial denture with a single tooth consisting of a base and artificial teeth, a klammer, while at one end of the clasp there is a mechanical device consisting of an internal internal matrix and an external matrix, made in the form of a hinge, and the second end is the klammer seat in the fixed nest on the artificial tooth crown, while the second end of the clasp is made with a bend for the seat, and the seat for the clasp is EHO tide with the guide, and the matrix of the hinge device is secured in the base of the prosthesis removably together with the base, and configured patrix inner spherical shoulder clasp and is connected with a seat.

Thus, the technical result of stable fixation of the klammer system, with the possibility of removal, increased chewing efficiency, aesthetics and elimination of the negative effect on the periodontal tooth is due to the fact that the clamp is made with the possibility of removal, the seat of the clasper in the socket is made on an artificial support crown of the tooth with lingual or palatal surface, and the shoulder is made in the form of a springing device, while the seat for the prosthesis on the clasp is installed at one end of the springing device a and consists of an internal patrica, made in the form of a ball and an external matrix, made in the form of a hinge device, the clasp seat in the socket is made in the form of a hollow square, and at the other end of the spring device the clasp seat is in the socket, the second end of the clasp is made with a bend for the seat, and the seat for the clasp is made with a guiding tide, while the hinge matrix is fixed in the basis of the prosthesis with the possibility of removal along with the base, and the inner part I have a spherical shape and are connected with a shoulder of a klamer, with a seat, that is, in the proposed clamping system, the clamp is fixed rigidly to the support crown, and the hinge part of the prosthesis is connected to the basis of the prosthesis.
