The Prosthesis Lining For A Better Denture Content

The Prosthesis Lining For A Better Denture Content

Due to the so-called prosthesis lining, the hold, the seat and thus also the function of an existing or older denture can be optimized. Suitable for relining are the total denture or full denture, partial dentures and combined dentures such as a telescopic denture. The part of a classic staple prosthesis worn by the mucous membrane (gum or alveolar crest) can also be relined.

In a prosthetic relining, either a hard or soft relining material is applied to the underside of the denture base. To do this, the dentist must map the current conditions in the mouth or jaw – through a denture impression. The dental prosthesis with the impression is then sent to the laboratory, where the dental technician makes the appropriate relining.

 

Hard Or Soft Relining

Hard Or Soft Relining

If the prosthesis is adjusted by means of relining to the changed conditions in the mouth, this only affects the base of the prosthesis and not the artificial rows of teeth. The relining material can be either soft or hard.

Relining directly in the dental office is also referred to as a chairside relining. It is, of course, important that the relining material hardens quickly and neither develops an unpleasant odor during processing nor requires high temperatures. Direct relines score with little time for the patient as well as comfortable results and are usually used for partial dentures. Biocompatible silicones or soft acrylates are used.

With a hard relining the same plastic is used from which the prosthesis was made.

 

When Is A Relining Necessary?

A full or partial denture must sit evenly on the alveolar ridge and gum in order to fully fulfill its function. However, even small changes in the jaw can cause the prosthesis stop is no longer optimal, the prosthesis then shakes when talking or chewing. Also, no longer properly fitting removable dentures, in the long run, can lead to problems such as inflammation or painful swelling in the oral cavity.

Since the bone substance in the jaw changes even with an optimally fitted prosthesis and gradually degrades over time, the prosthesis content can gradually deteriorate. In older people, this bone reduction is also accelerated, therefore, the correct fit of a prosthesis should be checked regularly by the dentist.

Even with small changes, a relining makes sense and should be made promptly by the dentist or in the dental laboratory. This helps to avoid heavier problems and restore comfort when wearing the prosthesis.

 

How Does The Treatment Work And How Long Does It Take?

The patient must bring some patience to be able to relinquish a full denture that is no longer optimally seated. Because this does not happen in the dental office but in the dental laboratory. The dentist first takes an impression of the jaw, whereby the prosthesis is used as an individual impression tray. This results in an exact image of the edentulous jaw and its surface structure, which is then sent by the dentist to the laboratory. There, the full denture is refined to ensure that the edge of the prosthesis again has optimal contact with the gums everywhere and sits stable after insertion.

 

What Speaks For A Prosthesis Lining

Full dentures in the edentulous jaw, but also partial dentures u. Ä. must rest perfectly on the gums, oral mucosa or the palate. The full denture gets its entire prosthesis content from the suction or negative pressure, which is optimal only with a perfect fit. If cavities remain or air can penetrate between the skin and the prosthesis, the denture relaxes.

The need to reline a prosthesis is usually due to changes in the oral cavity or on the jawbone. Thus, the gums or the jawbone may regress or deform over time, which may degrade the prosthesis contents or result in overloading of the abutment teeth. Thus, free endoprostheses, which are held by the own teeth, sink too far by a bone loss at the rear end, which leads in the long run that the chewing forces are diverted and the supporting teeth thereby become crooked or unstable.

The relining material is not a repair material to mend damaged or broken prostheses. Even an older denture must still be fundamentally intact and functional so that the relining worthwhile. Depending on the age of the denture, current findings and dental advice, it may be better to have a new prosthesis made, which sits better and firmer right from the start and may even look better.

 

How Much Is A Prosthesis Lining?

The cost of soft or hard relining a partial or full denture is between 100 and 300 euros, depending on the individual case. The statutory health insurance funds provide a subsidy for the treatment so that the own contribution for the patient is reduced. Anyone who has only a small pension in old age is also possibly considered a financial hardship case and receives the double fixed subsidy of the health insurance, whereby the own share for the prosthesis lining is again significantly reduced.
