Fixed Prothesis

The dental prosthesis is an artifact used to replace the original dentition lost or compromised for functional and / or aesthetic reasons. It also defines the denture part of dentistry that deals with the design and construction of prostheses, subject to the following requirements:

  1. functionality
  2. resistance
  3. harmlessness
  4. aesthetics

Fixed Prosthesis

The fixed prosthesis is fixed to the elements pillar with the cementation and can not be removed from the patient. Based on the features, there are three types of fixed prosthesis:

  1. fixed prosthetic reconstruction: has the task of rebuilding the anatomical parts of the removed tooth and then preserve it from complete destruction (eg. crowns, inlays, die pin);
  2. prosthesis replacement: it replaces with particular elements natural teeth lost (eg. intermediate elements of bridge prostheses);
  3. prosthesis fixation: has the ability to block and properly distribute chewing forces (eg. splints fixation).

These items if you anchor the tooth root or residue are defined crowns, if built on the adjacent teeth (properly filed) with the aim to restore missing teeth are called decks, and when applied on the bone implants are defined implant prosthetics.

Are defined prosthesis also fixing the veneers, which consist of ceramic shells to be applied on the front teeth for aesthetic or functional purposes.

In recent years great importance has taken the computer-assisted production of fixed restorations with CAD / CAM technology.

Crowns

The crowns are implants for single teeth of which at least the root is preserved. Are anchored or properly prepared tooth (stump) or via endodontic posts, the root (crown Richmond).

The crowns, as well as bridge elements, can be metal, ceramic metal, only ceramics. Currently they are presenting other materials useful for the fixed prosthesis.

Bridges

What bridges the extract dental element it is replaced by a prosthesis that also includes the adjacent dental elements which are for this reduced to stumps and prosthesized also.

The missing element together with the pillar elements (abutments on which leans) form the bridge. It can be total understanding that the whole arch (prostheses circular bridge) or part comprising two or more elements.

The pillar elements must have a number equal to or greater than the number of pillar roots of missing items, if it does not exist you run a mixed prostheses.

For girder it means the structure is allocated to support the item or items missing.

Porcelain Veneers

Porcelain veneers are thin ceramic plates which are cemented on the visible surface of the front teeth. The teeth that receive a veneer are slightly filed down to the ceramic spacer. However, their preparation is extremely conservative and should be maintained at the level of the surface portion of the tooth, the enamel. The enamel allows optimal bonding of the veneers to the tooth.
