DE102007011774A1 - Dental prosthesis parts attaching device, has place holder made of wax or suitable material, in its dimensions position of swing bolt blade, recess of holder to bolt axle and adjustment spring, and hollow space are recessed - Google Patents

Abstract

The device has a place holder made of wax or suitable material, where position of a swing bolt blade (3.0), a recess of the holder to a bolt axle and an adjustment spring (5.2) through two bores and a hollow space (1.5) required for pivoting the swing bolt blade are recessed at dental prostheses in a holder dimension. The holder fixes an engagement opening of the blade into a secondary part for insertion into a primary part e.g. rod (1.1). The holder is manufactured from ceramics, metal or silicone or other material for bringing into a mold.

Description

The The invention relates to a device for releasable connection of dental prostheses with the help of a pivoting bolt.

In Dental technology, such compounds are known and have become proven.

Simple shapes as under DE 8904863 are offered as a single bar leaf and integrated by the dental technician into a dental prosthesis construction to be manufactured. Here, the technician was forced to make the dentures around the prefabricated locking blade around. The possibility of major changes was not given. In order to obtain individual solutions, the experienced technician has made the self-locking blade according to the existing circumstances. The procedure is in the articles of the "Dental-Labor" Issue 11/1996 Page 1861f "An individual swing bar" , as in Issue 8/2000 Page 1209 f "Production of a Mono-Reductor with Swing Bar" set out in detail. A locking of the locking blade in the open or closed position was not described here and is only by a kind of clamping action (friction), or by the incorporation of an additional functional part (spring bolts, pins, screws or the like) possible and also very expensive. As alternatives are as under DE 3622689 . DE 3922976 . DE 4304868 and under EP 1611866 complete, mounted in housing latch elements offered, but which are very expensive. In addition, the pre-assembled parts with additional housing are often difficult to integrate into the dentures.

The aim of the invention is to offer a simply constructed pivot bolt, which is applicable without its own housing, a locking point in the open and closed position ( 3.1 ) and also easy and safe to process even for the inexperienced dental technician ( 1 ).

This is achieved by providing a placeholder ( 2 ), with the help of which the position of the metal sheet ( 3 ), and the bolt axis, the locking spring ( 4 ), and the space required for pivoting the latch leaf in the dentures ( 1.5 ) is omitted.

The actual functional part is the bolt blade ( 3 ), whose shape is determined by the rotational movement due to the axial position and the position of the spring and is replaced after completion against the placeholder.

Other components are axis ( 4.1 ) and locking spring ( 4.2 ), preferably in one piece ( 4 ). In order to ensure the spring travel of the locking spring, it is recommended to use the Patzhalter spring ( 5 ) in the production of the secondary part. Also, a reduced duplicate placeholder ( 2a ) for the production of a reduced secondary part in the model casting process.

The application of the locking points ( 3.1 ) and the sliding surface of the locking spring ( 3.2 ) on the outer edge of the locking blade ( 3 ) can also be placed closer to the bolt axis, into the interior of the bolt blade ( 6 ), whereby other bolt blade embodiments can be designed using this novel locking technique ( 7 . 8th and 9 ).

In the simplest embodiment, bolt leaf, axle and spring are poured into the plastic to be applied in one operation during the completion of the dental prosthesis ( 1 . 1.4 ). For this purpose, the combined placeholder spring with axis ( 5 ) in the holes provided in the placeholder, in this case made of wax ( 2.1 ) and in the opening of the previously with the reduced placeholder ( 2.3 ), reduced metal abutment ( 1.2 ). Bar axle and locking spring, as well as parts of the latch blade are hereby stored in the completion of the prosthesis in plastic ( 1 ). This allows a simple design of the plastic base when working out the plastic part ( 1.4 ). After completion of the design and polishing of the prosthesis base, the placeholders for spring and locking blade ( 5 ) and through the final parts ( 3 + 4 ) replaced. A stable locking of the dental prosthesis is achieved by reaching through the metal latch plate ( 3.0 ) through the reduced metal secondary part ( 1.2 ) in the primary part ( 1.1 ) guaranteed.

Using a wildcard ( 2 ) made of metal or other suitable for wrapping with wax and / or modeling plastic materials, can be carried out using the direct modeling technique, the storage of the pivot bolt blade, as well as all functional parts in metal.

With the new type of swing bar and the coordinated auxiliary and functional parts, the dental technician can essentially focus on the cosmetic design of the dentures. The function of the pivoting bolt is through the coordinated Parts are always guaranteed even for the inexperienced technician.
