Crown and Bridge Restorations

Tooth Crowns

A cosmetic dental tooth crown is a laboratory-constructed restoration which covers all or part of a broken or damaged tooth in order to improve strength, appearance and function. Today, tooth crowns are typically made from porcelain fused to gold alloys or ceramic, which is stronger than the traditional porcelain. These cosmetically superior materials, together with advances in dental equipment and technology, makes a crown on a tooth virtually undistinguishable from its neighbours.

Tooth crowns can be used to restore badly broken down teeth; to alter the shape, size or inclination of teeth for improved function and/or aesthetics; to rebuild a mouth with excessive tooth wear; to provide support for dental bridges and dentures; to protect root treated teeth or to cover severely stained or discoloured teeth.

All prosthodontic work is designed to be as aesthetically pleasing as possible. It is essential that patients play an active part in their treatment and to convey their exact desires and expectations. A crown for a tooth is prepared in conjunction with our laboratory technicians to analyse the shade, shape and size to meet our patients’ individual requirements.

In conjunction with other cosmetic dental techniques, tooth crowns can be utilised as part of a full mouth reconstruction.

Dental Bridges

A cosmetic dental bridge is a laboratory-constructed permanent replacement for one or more missing teeth, fixed by attachment to the adjacent standing teeth. A dental bridge is essentially used to ‘bridge the gap’ between the remaining adjacent teeth restoring aesthetics, function and bite. It usually occupies no more space than the original dentition.

Dental bridges are used to improve appearance, function and masticatory efficiency; to prevent adjacent teeth from drifting and tilting and the opposing tooth from overerupting; to prevent food impaction which can result in gum disease and future tooth loss; and to improve speech.

There are several types of dental bridges:

  • » Conventional Bridges can be constructed from metal or porcelain, or a combination of the two. These dental bridges involve removing tooth tissue, or a previous restoration and replacing it with a tooth crown or inlay. This means conventional bridges may be destructive to tooth tissue and can be time consuming.
  • » Minimal Preparation Bridges involve attaching the artificial tooth or teeth via a metal plate to the minimally prepared inner surface of adjacent teeth. These dental bridges can only be used when the adjacent teeth have sufficient intact enamel, and when the occlusion, or bite, is favourable. Minimal preparation bridges also have a slightly increased tendency of de-cementing.
  • » Implant Supported Bridges are screwed to the implants below. In many situations, a dental implant can support more than one tooth unit, however, the number of implants needed to support the dental bridge varies according to the individual patient’s circumstance. There are always many alternatives to restore a missing tooth or teeth. The advantages and disadvantages of the varying options are explained to our patients who are always an essential part of the treatment planning process.
