crowns and bridges

crowns:

A dental crown is a tooth-shaped "cap" that is placed over a tooth to cover the tooth, restoring its shape, size, strength, function and aesthetics. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Why is a crown necessary?

  • Broken down or excessively worn down tooth with weakened tooth structure
  • To place a bridge for a missing tooth
  • To improve cosmetic appearance
  • To cover a dental implant


At Edgecliff Dental Care we endeavour to use:

  • Advanced dental care 
  • Cutting Edge dental care and
  • Today’s dental technology

 

To provide Precision dental fit, we mainly use  All ceramic or Zirconia crowns, constructed by a quality, Australian dental laboratory.

 

there are 4 types of dental crowns:

All Ceramic crowns are a porcelain-based filling material and recommended for restoring front teeth due to colour blending with the natural teeth.

Zirconia crowns are a popular type of all ceramic crown, which gives improved appearance of a tooth which has become stained or disfigured over the years. They are durable, and long lasting and are very compatible with the soft tissues. It is safe to use and preferred by many people to porcelain fused to metal crowns. 

Porcelain fused to metal is connected to the outside of a metal structure to provide strength to the teeth as well as provide a good seal to prevent leakage and decrease recurrent dental decay. When porcelain is fused to metal, it provides a stronger restoration than porcelain alone, it is very durable and strong but sometimes create an unnatural looking dark margin around the gum.

Gold alloys are comprised of gold, copper and other metals and provide a strong material to adhere to the tooth structure. Gold alloy is resistant to wear and fracture and does not wear away the teeth it comes in contact with. This material is highly biocompatible with the gum tissue. Usually used on back molars where forces exerted during chewing can be very high.

 

bridges

A dental bridge is an alternative to a dental implant or a denture to replace missing teeth.

It is important that missing teeth are replaced to prevent the remaining teeth from shifting over towards the gap or opposing teeth over erupting. These changes can lead to further problems such as food impaction, decay, gum disease, Jaw joint dysfunction and poor aesthetics.

There are two types of bridge to consider: the dental bridge which is worn for corrective purposes and cosmetic bridges which also do this but help to enhance the appearance of the teeth

what is a dental bridge?

It is a dental restoration, which consists of a false tooth - known as a pontic, which lies usually between two crowns. These crowns help to secure the pontic in place, effectively bridging the gap left by a missing tooth.

The pontic sits in the gap and the two crowns fit over natural teeth on each side of this gap. This helps to support these teeth and prevents them from leaning into the gap.

A bridge can be fabricated from a variety of materials including; gold, ceramic or alloys. The all ceramic bridge is often preferred to the metal ceramic bridge for aesthetic reasons.
