Fixed dental prostheses

Fixed dental prostheses

The crown – as its name indicates – restores the external surface of the tooth and so it restores its chewing ability and aesthetic appearance. These are most often used in cases when after eliminating the damaged dental structure the healthy structure is not enough, so a durable support for the tooth filling is not possible. In this case the best and most secure solution is to complete the remaining structure and then to unite the healthy and the restored structures using a crown.

If there is an edentulous area between the teeth, the crown is not enough for its restoration. In this case – depending on the quantity and position of the remaining teeth – there is need for a fixed prosthesis. This consists of crown parts fixed on the teeth surrounding the edentulous area and the gap between these is filled with one or more restored teeth supported by these parts. This is called fixed partial denture or FPD.

Cases in which one could need a crown or FPD:

  • In the case of restoration of a totally damaged crown part when the respective tooth cannot be restored by using a (new) filling.
  • A crown is recommended also in the case of a tooth with root canal therapy. It is beneficial both functionally and aesthetically, especially if we have to realize a pin abutment, because practically only root has remained from the tooth. The method is the same in the case of implants.
  • In the case of worn or broken teeth or in the case of teeth being in wrong position.
  • It can support a partial denture or can bridge over an edentulous area.

The process of making a dental crown (after consultation and elaboration of the therapeutical plan):

  • Preparation of the respective tooth (teeth)
  • Impressing
  • We put a temporary crown/FPD on the prepared tooth (teeth)
  • Making the crown in a laboratory
  • Eventual tests (test for the frame, test before dental curing light)
  • Crown cementation
