Fixed Prosthodontic And Veneers
A fixed prosthesis is defined as a restoration or replacement which can not be removed from the oral cavity. They can be “crowns” or “bridges” supported by natural teeth or implants and their aesthetic and comfort are similar to natural teeth.
Thanks to the great development of new materials (prosthesis without metal core and ceramic materials) and biomedical technology (computer technology CAD/CAM), today restorations have a tooth-like appearance, making them difficult to distinguish from natural teeth (eg . the light core of these crowns doesn’t make show the black shadow of the metal border from the gum) .
Nowadays, thanks to minimally invasive procedures, such as veneers, it is possible to reshape entire smiles, reducing dental preparations and ensuring structural integrity and longevity of restorations.
Full ceramic crowns & bridges
When teeth are more severely decayed due to existing restorations, carious diseases or wear and erosion, fracture or old canal treatments, a full tooth coverage might be necessary.
If one or more teeth is missing, the prosthesis is called “bridge”: the teeth that support the bridge are called pillars or abutments, while intermediate elements are called pontic.
Why is it important to restore a missing tooth ?
Porcelain veneers are thin restorations which replace enamel on the buccal surface of anterior teeth, the visible one in contact with lips.
They allow major tooth color and shape corrections to be performed with minimal tissue sacrifice or risk for the vitality of the tooth. Sometimes they are only addictive, that means no drill.
Another advantage of porcelain veneers is the absence of framework, which allows for optimal light transmission and therefore superb aesthetic results.
The main indications are:
Contraindications are few, such as presence of bad habits (bruxism), a head to head bite (upper and lower jaws aligned if look from the side), lack of enamel on the tooth surface or excessive discoloration of the tooth.
