DENTAL CROWNS
Crowns, also known as caps, restore damaged teeth and mimics the shape, size and color of the surrounding teeth. Crowns are indicated for cracked teeth and teeth with deep cavities; to protect teeth that have been filled by root-canal treatment; to provide extra support for bridges; and to cover poorly shaped or discolored teeth. Crowns may be made of metal, porcelain, or newer restorative materials like metal free ceramics. They are custom-made and fitted for each patient in conformation with the size and length of the natural teeth.
The teeth to be crowned are prepared which involves reduction of the tooth size (usually under local anaesthesia) followed by an impression or mould of the prepared tooth. This trimming of the tooth is required to create space for the crown to be fitted. The mould taken is then sent to a laboratory where skilled technicians will fabricate the crown. In the meanwhile, a temporary crown is made and fitted onto the trimmed tooth.
DENTAL BRIDGES
Dental bridges can be used to replace a small number of missing teeth if the neighboring teeth are sufficiently strong. The number of missing teeth, condition of the neighboring teeth, condition of the supporting gums and bone are all important factors which need to be assessed prior to making a bridge.
They are permanent, fixed alternatives to tedious removable partial dentures. The missing teeth are replaced with an artificial tooth connected between two crowns (caps) that are permanently connected on the adjacent teeth. Dental bridges may be made of metal, porcelain, or newer restorative materials like metal free ceramics/zirconia
