How to reline the denture?

If the fit of a denture is no longer 100% guaranteed, the dentist recommends relining it. There are two methods of relining. In the first one, an impression is taken with the denture, which shows the areas of the jaw ridge and palate where material is missing.

At these places the denture lies hollow and wobbles. The technician fills up the areas where material is missing and the jaw has receded with acrylic. This described procedure is the indirect relining. In the other procedure, direct relining, the liquid acrylic is applied directly to the denture base and placed in the mouth until it hardens. Afterwards, the new margins are finished by the technician.

How to glue a dental prosthesis?

If a denture is broken, it must be repaired. It does not work to treat it with an adhesive, because in many cases the fragments cannot be put together without a gap and the prosthesis therefore no longer fits. Often the dentist has to take an over impression of the fragments in the mouth to determine the correct position of the prosthesis.

The dental technician, knows from the impression exactly how the prosthesis has to be assembled. A plaster model is made in the laboratory to fix the fragments in the correct position, the fragments are roughened at the fracture site and the technician adds new plastic material to the fracture gap. After hardening, the gap is finished, smoothed and polished.

This is the only way to restore the stability of the denture. Glue cannot fill the fracture gap in a stable and correct position. It is also toxic, harmful to the oral cavity and must not be swallowed. Therefore, it is generally not recommended to try to repair the prosthesis yourself.

What adhesives are available?

Adhesives are aids for prosthesis wearers, without which many users would have virtually no prosthesis support. This is particularly true for users who have little or no salivary flow, which is crucial for the suction effect of the prosthesis. The most popular adhesive is the classic adhesive cream, which is characterized by a rather viscous, almost mushy consistency.

This adhesive cream is distributed in approximately hazelnut-sized portions on the denture base and increases the viscosity and hold of the denture. If teeth or implants are still present, the adhesive cream should only be applied to surfaces where no retaining elements are present. Furthermore, there are powdered adhesive agents available which are simply spread in a thin layer on the denture base and provide optimal hold for hours when inserting the denture.

The powder consists of sodium alginate and is particularly suitable as a bonding agent. For particularly sensitive mucous membranes, which tend to form pressure points, there are adhesive pads which are cut to size and moistened for the prosthesis.The adhesive pads provide optimal hold and cushion the prosthesis at the same time. This protects the mucous membrane from inflammation and pressure points and fills hollow areas like a relining material. In general, a prosthesis should not require adhesive material for optimum hold.
