Kuretovy's clasp system for removable partial denture of single tooth

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to orthopaedic dentistry, and can be used for partial laminar and clasp prostheses. A clasp system for fixing a removable partial denture of a single tooth consists of a basis with artificial teeth and a denture clasp. One end of the clasp comprises a mechanical device consisting of an inner O-ring abutment and an outer matrix and configured as a pivot, while the other end comprises a clasp seat in a rigid socket on an artificial dental crown. The outer matrix is fixed in the prosthesis basis and detachable together with the prosthesis, while the inner O-ring abutment is ball-shaped and connected to a clasp arm. The seat of the clasp socket is mounted on the artificial dental crown vertically or horizontally either from the lingual, or palatal, or approximal surface.

EFFECT: invention enables providing a more stable fixation of the detachable clasp system, a masticatory effectiveness and an appearance, and also avoiding the negative effect on the parodontium.

The technical field to which the invention relates.

The invention relates to medicine, in particular to klammern systems for removable partial denture with single small tooth, and can be used in prosthetic dentistry for partial plate and clasp dentures.

The level of technology

A known method of manufacture of removable partial denture on the upper and lower jaw with a single standing tooth, which includes the manufacture of artificial crowns on the remaining tooth (sometimes without artificial crowns), the manufacture of removable partial denture with klammern fixation on the teeth, while partial dentures are made in compliance with all known clinical and laboratory stages (see C. N. Kopeikin, L. M. Demmer. Prosthodontic appliances. - M.: Medicine, 1985. - S. 206-231).

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

A known method of manufacture of removable partial denture with single small tooth, including the manufacture of an artificial crown on a tooth, removing the mold from the jaw, making basis with bite roller, determination of Central occlusion, manufacture of metal clasps for a tooth, the production of artificial teeth, the fit of the wax design is the work of the prosthesis in the oral cavity of the patient, replacement wax base plastic, and polishing the denture, overlay finish the denture to the jaw, while standing on a single tooth of the patient made an artificial crown with two patricai on her approximal surfaces, plastic base partial removable prosthesis welded individually fabricated metal frame consisting of metal wire mesh and metal element matrices to contain Patric artificial crown (see U.S. Pat. RU # 2352287, IPC A61C 13/00, publ. 20.04.2009,).

The disadvantage of this method is that klammern fixation does not always ensure a good fixation of the denture with single small tooth, often there is a breakdown of the basis in the field of single standing of the tooth, as this is the weakest point.

Closest to the technical essence and the achieved positive effect and adopted by the authors for the prototype is klammern system for partial plate and clasp prostheses containing a basis on which a set of artificial teeth, crowns Klammer, consisting of a seat for the prosthesis on the klamer, shoulder and seat of klamer into the slot (see E. I. Gavrilov, I. M. alshits. Prosthetic dentistry. Medicine, Moscow, 1979, S. 206).

The disadvantage of this klammern systems what is that clammer with the prosthesis is connected to the base of the prosthesis, and this compound in the region of the anterior teeth, especially the upper, unaesthetic, as seen on the teeth, as well as clammer has a negative effect on the periodontal tooth.

Disclosure of inventions

The task of the invention is to develop klammern system for removable partial denture with single small tooth with a stable fixation, increased chewing efficiency, aesthetics and with the exception of a negative effect on the periodontium of the tooth due to the soft load transfer at the tooth over his shoulder, made in the form of constantly springing device and the location of the clamp from the lingual or palatal, or approximal tooth surfaces with the possibility of release.

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

The technical result is achieved by using klammern system for fixation of removable partial denture with single small tooth, consisting of a base with artificial teeth and denture clasps, with one end of the clamp is a mechanical device, consisting of Patricia EXT is na and outer matrix, made in the form of a hinge, and the second end of the seat clamp in a stationary nest on artificial tooth crown, and the matrix of the outer fixed in the base of the prosthesis with the possibility of removal together with the prosthesis, and Patricia internal executed spherical shape and is connected to the shoulder-clasps, and the seat into the slot of the clamp is made on the artificial tooth crown vertically or horizontally from the lingual or palatal, or approximal surfaces.

The technical result is achieved by using klammern system for removable partial denture with single small tooth in which the system is installed on the plate prosthesis.

The technical result is achieved by using clamerey system for removable partial denture with single small tooth, in which the matrix of the outer fixed in the saddle-shaped part of a denture clasp.

Thus, the technical result is achieved by using klammern system for removable partial denture with single small tooth, in which seat in sockets clamp is made on the artificial tooth crown vertically or horizontally with the lingual or palatal or approximal surfaces. Thus, the technical result of stable fixation klammern system with the possibility of removal, increased chewing effectively the tee, aesthetics and eliminate the negative effects on periodontal tooth is due to the fact that clammer made with the possibility of removal, seat in the socket of the clamp is made on the artificial tooth from the lingual or palatal, or approximal surface, and the shoulder is made in the form of a spring device, with a seat for the prosthesis on clammer installed at one end of the spring device and consists of Patricia inner made of spherical shape, and the outer matrix, made in the form of hinge or locking device, and a seat in the socket of the clamp is made in the form of a hollow rectangle, and at the other end of the spring device is a seat in the socket of the clamp, while Klammer with seats mounted on the artificial tooth crown is stationary, and also due to the fact that the seat in the socket of the clamp is made on the artificial tooth crown vertically or horizontally from the lingual or palatal, or approximal surfaces.

SUBSTANCE: the present innovation deals with reconstructing a patient's anatomical dental shape in case of increased erosion of solid dental tissues. The method should be implemented due to molding a model, manufacturing a wax cap for the stump of the treated tooth, modeling anatomical shape of supporting crowns, modeling an intermediate part and transforming wax composition into metal due to molding according to certain models. At the stage of modeling of anatomical shape of supporting crowns one should fix retention pearls of different diameter to the surface of the wax cap being of 0.3 mm thickness: gradually from the least diameter of 0.1 mm in the region of cervical area to the greatest diameter being up to 2.0 mm in equator area and mastication surface; with the help of modeling wax it is necessary to fill in the spaces between the pearls to fulfill the modeling of dental anatomical shape by not being beyond the surfaces of pearls, moreover, one should obtain wax composition of the desired thickness. The innovation prolongs the expiry terms of the denture suggested.
