Dental reconstruction

Definition

After a tooth has been extracted or had a root canal, it is necessary to replace or strenghten it. Actually, a too weak tooth could break in a short or a medium term, and therefore could be extracted.
A dental crown is a fixed prosthesis made of ceramic the same colour as your other teeth. Crowns enable very damaged or fractured teeth, teeth that have had endodontic treatment or major defective fillings to be repaired in an aesthetically pleasing and solid manner and can also be fitted onto an implant.

Furthermore, the extraction of a tooth causes an imbalance of all the occlusion:

– The neighboring teeth falls over: the opposing teeth migrates in the space created by the extraction, what provokes an interference in the movements of chewing and will engender in the long term a deterioration of the joint of the jaw.

– The chewing will be much less effective of the side where is missing a tooth so that the chewing will become unilateral with consequences at the level of the articulation.

– If several posterior teeth are extracted, the chewing will be made with the front teeth of the mouth: the incisors which are not resistant to the strengths of the chewing, will fall over gradually, entailing an overhang of the chin and a decrease of the vertical dimension of occlusion which will age the face.

– It also causes the movement of teeth surrounding the site of extraction, what will predispose to bruxism (abnormal strengths on teeth).

– The misalignment of teeth will favor the development of a periodontal disease (disease which destroys support tissues of teeth)

– Finally, aesthetically, the absence of a tooth or several teeth is a sign of ageing.

If adjacent teeth are damaged, the dentists of the Lancy Dental Center  can make a bridge to replace it. Bridges are permanently fixed to neighbouring teeth and replace one or two missing teeth. They are used when the adjacent teeth and gums are in good condition, otherwise a dental implant is fitted.

 

Two kinds of dental bridges and crowns are currently available:

  1. Metal ceramic: a gold frame (metal section) base and the cosmetic section on top made of ceramic (tooth-coloured)
  2. All-ceramic: the whole crown or bridge is made of ceramic (no metal, cosmetic)

As an alternative to a fixed prosthesis, your dentist could also fit a partial or complete removable prosthesis. There are two types of removable prosthesis:

  1. A partial removable prosthesis, attached using hooks that are affixed to the neighbouring teeth. This solution can replace several missing teeth.
  2. A complete prosthesis, also called dentures, which replaces all the teeth.

If removable prosthesis have for advantage their cost, they have many inconveniences  : they are mobile, voluminous, and patients have often difficulties in accepting them. They also can cause wounds of gums because of the regular micro-fictions ( ulcers ).

Finally, when a tooth is broken or poses a cosmetic issue (this could be in relation to colour, form, position,…), the Lancy Dental Centre dentists can carry out cosmetic procedures like fitting veneers and teeth whitening.
