Denture-fixing attachment having freely adjustable angle and position

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly, to orthopaedic dentistry, and is intended for dental prosthesis fixing on fixture. Denture-fixing attachment freely adjustable in angle and position comprises a rotation guide member, cover for ball joint angle and ball joint restriction. Rotation guide member is installed at the center of the denture-fixing attachment and has a lower portion, to be inserted into a fixture groove of a fixture, so that the rotation guide member may be coupled with the fixture having the fixture groove. Ball joint angle restriction cover positioned on the rotation guide member and has a through hole vertically formed through an inner part of the ball joint angle restriction cover. Ball joint has a ball joint lower portion is connected to the upper portion of an rotation guide member so that it can be rotated for the direction of rotation, recessed in a shape of a half-moon and placed in the ball joint angle restriction cover.

EFFECT: invention enables making the simple denture-fixing attachment with minimum number of sequentially connected members, providing the possibility of fixing of several fixtures, arranged in parallel to each other.

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.

SUBSTANCE: invention relates to field of medicine, namely to orthopedic dentistry and can be used in manufacturing of clasp telescopic prostheses with additional lock fastening. Method of manufacturing of additional lock fastening for clasp telescopic prosthesis includes several stages. At the stage of modelling wax reproduction of internal telescopic crowns on their distal surfaces performed is installation of additional lock fastenings in form of industrial workpieces of attachment with preservation of diametrical location of support teeth. Casting from metal of internal telescopic crowns with spherical projections is carried out. Fixation of medium rigidity matrices is performed on spherical projection of internal telescopic crown, model is prepared for process of duplication with isolation of clearance between lower matrix surface and mucosa of prosthesis bed. Wax modelling of framework of clasp telescopic prosthesis with external telescopic crowns on fireproof model is carried out. After casting framework of clasp prosthesis by traditional method, inside framework of detachable part of clasp prosthesis socket for installation of matrices under spherical projection is formed. After casting framework of clasp prosthesis by traditional method, fitting of metal construction without matrices is performed.

EFFECT: increased quality of prosthetics due to application of additional lock fastening, with possibility of its re-activation and ensuring prolongation of prosthesis service terms, without essential change of traditional process of manufacturing of telescopic clasp prostheses.

SUBSTANCE: device has base manufactured from dental superelastic casting titanium nickelide having denture clasp on bearing teeth and saddle-shaped segments in failing teeth zones produced as plates. The artificial denture is attached to the plates with flexible polymer ligaments. The saddle-shaped segments are manufactured as meander row attached to base body via middle portions of end plates in the row. Polymer ligament flexibility is higher than meander row plate waves flexibility.

EFFECT: reduced risk of abnormal underlying tissue changes.

SUBSTANCE: device has base bearing artificial teeth, clasp and cramp iron members joined to bases provided with flexible envelope. The flexible envelope, rotatable when taking off or setting prosthesis, is fastened to cramp iron member and fixed in longitudinal direction by means of thickenings on cramp iron hook tips which sizes are not greater than external diameters of flexible envelope or internal flexible envelope surface prominence and counterpart grooves on the cramp iron members.

EFFECT: excluded anchorage teeth loosening.
