Prosthetic bridges belong to permanent prosthetic restorations, used to fill a gap or gaps in the dental arch left by missing teeth. A typical prosthetic bridge consists of prosthetic crowns placed on abutment teeth (or implants) connected with the pontic or pontics (artificial teeth), replacing the missing teeth.

Based on the type of material used, they are divided into:

  • ceramic bridges (made on a metal base –common steel or gold),
  • all-ceramic bridges,
  • composite or acrylic inlay bridges used as a temporary solution.

ADHESIVE BRIDGES

In case of single missing teeth, particularly those on the front,  in order to avoid the necessity of stripping often healthy dental tissues, we use a system of adhesive bridges known as Maryland. It provides excellent aesthetic results and patient comfort without the need for stripping adjacent teeth. The method itself consists in the reconstruction of the missing tooth with a new-generation composite material and fixing it to the lingual (internal) surfaces of the adjacent teeth by means of strong and extremely durable glass fibre.

CONVENTIONAL BRIDGES

This solution guarantees excellent aesthetic and functional results, as well as convenient use for the patient. The main inconvenience related to conventional bridges is the necessity of stripping at least two teeth adjacent to the gap. Depending on the patient’s preferences, the location of the missing tooth/teeth and the aesthetic requirements, all-ceramic or complex bridges are used. The former guarantee best cosmetic results, while the latter consist of a metal framework covered with aesthetic material (porcelain, composite) that imitates the shape and colour of the missing dentition. This type of restoration may be supported on both natural teeth and implants.

TYPES OF PROSTHETIC BRIDGES

Based on the type of material used, they are divided into:

  • ceramic bridges (made on a metal base – common steel or gold),
  • all-ceramic bridges,
  • composite or acrylic inlay bridges used as a temporary solution.

The procedure of fitting a prosthetic bridge is very similar to fitting a crown (see -> crowns).
