DE2430667A1 - Dental prosthesis with magnetic jaw fixing arrangement - has inserted magnets and jaw bone to hold denture in place - Google Patents

Abstract

A dental prosthesis with a jaw affixing device is constructed such that the fixing device consists of inset permanent magnets (6) or permanent magnets in combination with soft iron pieces (5) which are inset into the jaws (1, 2) and the dental prosthesis (3). If two permanent magents (6) are used then they have opposite poles. Both magnet (6) and soft iron pieces (5) are given protective coatings such as plastics or metal alloys which are time compatible. The inset magnets (6) or iron pieces (5) are inset into the jaw bones (1, 2) and covered with skin flaps. Both magnets (6) and iron pieces (5) are three dimensional in form.

Description

Dental prosthesis The invention relates to a dental prosthesis with an adhesive device to attach to the jaw. Dental prostheses are nowadays usually made by braces, Suckers, adequate prosthesis adhesive bearings, implants or other means on the human Lower and upper jaw attached. Because the correct fit of the dentures is essential depends on a sufficient adhesive position in the upper and lower jaw inadequate detention camp for an insufficient prosthesis fit. Inadequate detention camps step e.g.

if the envelope is too low, creases in the cheeks and / or too high Floor of the mouth open. So far, either an operative one has been used to remedy these difficulties Changes to the folds and / or the floor of the mouth are necessary or implants are required necessary to stabilize the prosthesis.

However, this is at the risk of preprosthetic operations Type and disadvantages of implants referenced. In the case of implant prostheses, there is a continuous Communication between bones and oral cavity that promotes osteomyelitis (inflammation of the bone marrow).

The invention is therefore based on the object with simple means To create an adhesive device for dentures that are permanent in the lower and lower part Upper jaw can be provided and independent of an adhesive bed, implants and other fasteners in the size used today.

This object is achieved according to the invention in that the adhesive device by recessed in opposite positions in the jaw and in the prosthesis Permanent magnets or in combination with soft iron parts is formed.

To increase the adhesive forces, two permanent magnets are preferably used arranged opposite one another. The permanent magnets or soft iron parts are equipped with a Protective cover covered. A tissue-friendly plastic is preferably used as the coating or a metal alloy for use.

The permanent magnets or soft iron parts embedded or placed in the jaw are covered by a mucoperiosteal flap or a skin graft. The permanent magnets or soft iron parts can be designed in any three-dimensional shape.

The idea of the invention is based on the stalk in an imple mentation case attached drawing explained in more detail, which schematically a Shows cross-section through a human lower and upper jaw.

The magnets 6 are in the bones la and 2a of the upper and lower jaw 1 and 2 after folding down the mucous membrane and periosteum in the shape of a magnet 6 appropriately prepared bed embedded or placed on the jawbone. A fixation, if at all necessary, is done using suitable adhesives, springs, Screws or wires. After impacting, the periosteal flap of the mucous membrane is applied covers the implant.

In the prostheses 3 made of plastic are in the ridge resting on the alveolar ridge Part also one or more magnets 6 opposite those in the bone la or 2a anchored magnet 6 embedded. The magnets 6 are therefore in the prosthesis 5 on the one hand enclosed by the artificial tooth 4 and on the other hand by the denture resin.

Depending on the strength of the magnets 6, it is also possible to use the associated train opposite iron part as a soft iron core 5, as is the case with the lower jaw 2 is shown.

The magnets 6 or soft iron parts 5 can be in any three-dimensional Form and are made with a tissue-friendly plastic or metal alloy overdrawn.

This design has the advantage that in the upper jaw 1, lower jaw 2 and the corresponding prostheses or superimposed Magnets 6 or soft iron parts 5 guarantee a good fit of the prosthesis.

At the moment the usual camps, implants, clamps, suckers and others Holding and supporting elements are omitted in this holding device according to the invention.
