Non-removable dentures

If there is one or more teeth missed it is necessary to replace them very soon. The reasons are not only aesthetical or for effective chewing but also due to the cause that teeth are not immobile, teeth around the defect can start to move or teeth from the opposite jaw can draw into free spaces. Such self-displacement can lead to the development of malocclusion.

For the replacement of missing teeth the most convenient for patients are non-removable dentures. It means that restoration after placement into mouth stays there, it is non-removable, and it is immobile. Patients feel psychological comfort and are safe that size of restoration is similar with their natural teeth. It is very important aspect as one of the main tasks for prosthetist is achievement of maximum similarity with natural situation, as anything excessive causes the feeling of discomfort.

There are several types of non-removable appliances:

  • A bridge is a denture which is used in the cases if only one or several nearly located teeth are missed. The bridge is a construction fixed on the patient`s healthy teeth and replacing patient`s missing teeth. In such situations the natural teeth are grinded and lab produces bridges for the fixation on them. Positive is that restoration is non-removable; negative – healthy teeth are grinded. Bridges alike the crowns can be made of plastic, or cast metal, metal composite, metal ceramic, and zirconium oxide.
  • Implant or so called artificial roots of the teeth. Implants are made of extra resistant materials such as casts of metal with titan or alike. Implants are screw-shaped. Under anaesthesia they are screwed into bone, then they osseointegrate (grow) into bone during 3-8 months depending on situation. After this period an implant can be used as a support for the following restoration. Most commonly crowns are made of metal ceramic and porcelain. Implant supported constructions are very optimal approach for restoration because no healthy teeth are involved (the system functions independently); implants often are only way to avoid removable dentures.
