Large tooth gaps can hardly be concealed, even in the posterior molar region. A dental prosthesis ensures that you will appear self-confident again in everyday life with a complete smile. Find out here which dentures there are, how the treatment proceeds and what costs you have to expect.
How is a dental prosthesis used?
A dental prosthesis is usually used when tooth gaps are so wide that they cannot be closed by one or even several bridges.
Bridges have a higher wearing comfort, a better hold and a longer durability. For this reason, a bridge over a denture is the preferred instrument for closing tooth gaps when sufficient anchorage options are available.
What species are there?
Depending on the size of the tooth gap or anchoring possibilities, different prostheses can be used for treatment:
- Model casting prosthesis
- telescope prosthesis
- Implant supported prosthesis
- total prosthesis
The costs vary accordingly.
Model casting prosthesis
A model cast denture is a partial denture that is attached to the remaining natural teeth with the help of cast metal clasps. This denture is made of a metal alloy, which ensures a firm hold on the clasps. The imitation gums and teeth made of plastic are attached to it. The model casting prosthesis, also called the staple prosthesis, is the simplest of the variants.
A telescopic prosthesis is also a partial prosthesis that can be used to close tooth gaps. In contrast to the model casting prosthesis, the telescopic prosthesis does not require anchoring with clasps. Double crowns are used to anchor the prosthesis, so-called telescopic crowns, which consist of two parts. The primary crown (inner telescope) is attached to the tooth stump and is made of metal. The secondary crown (outer telescope) is worked into the partial denture and can then be placed on the primary crown and removed for cleaning. The telescopic prosthesis can be used in the lower and upper jaw.
Implant supported prosthesis
Implant-supported dentures are used when you have few or no teeth left. The prosthesis can then be attached to one or more implants, i.e. artificially inserted tooth roots.
A full denture is used to replace all of the teeth. Thus the full denture includes all teeth of an upper or lower jaw. Removable dentures in the form of full dentures are usually made of pink plastic (PMMA). Teeth made of plastic are also placed on these. Since a full denture is not supported by an implant or a crown, other means must be used to guarantee an optimal hold. With this dental prosthesis, so-called functional or valve edges are attached, which create a negative pressure between the prosthesis and the jaw mucosa when the prosthesis is inserted. If you have sufficient saliva production, this negative pressure as well as additional natural forces between jaw and prosthesis (adhesive forces) ensure a stable and secure hold of the full prosthesis. An accurate bite registration and subsequent impression of the jaw are also essential for a good hold.
This is how the treatment of a dental prosthesis works
Dentures are particularly time-consuming to manufacture and fit and therefore always require several dentist sessions, in most cases at least four.
Depending on the type of prosthesis, the procedure and thus the course of treatment also differ.
Treatment procedure for model casting prostheses
Since model casting dentures are attached to the remaining teeth by clasps and are thus worn, this type of prosthesis can be used comparatively quickly.
It therefore usually requires fewer sessions. First, impressions are taken for the prosthesis and the clasps, which are to be attached to the remaining teeth, are prepared. Once the framework has been cast in denture resin, the clasps can be attached to the corresponding teeth and the denture can be inserted.
Treatment procedure for implant-supported prostheses
Treatment with an implant-supported denture takes significantly longer.
The reason for this is the insertion and healing of one or more implants, which precedes the actual insertion of a prosthesis. The healing phase of an implant usually lasts two to three months in the lower jaw and two to three months longer in the upper jaw. The actual treatment for the denture can therefore only begin after this time.
Treatment procedure for full dentures
The duration of treatment with a full prosthesis also lasts longer, as up to 7 sessions are usually scheduled.
Temporary prosthesis until the prosthesis is completed is useful if it gives you a better feeling for the time until the prosthesis is placed.
