Restoration with Crowns and Bridges

Bridges and crowns are fixed prosthetic devices that are cemented onto existing teeth or implants by a dentist or prosthodontist.

 

 

 

 

1.ALL CERAMIC (PORCELAIN BASED)

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

Advantages:

  • Superior Aesthetics,Natural Appearance

The lustrous (shiny, glossy, luminous, sparkling, glistening) look of a natural tooth is generated by the way light penetrates into its enamel layer and then is reflected back out. The goal of porcelain crown construction is to mimic this effect.

  • Biocompatibility

The types of ceramics used to make them are typically no more abrasive than dental enamel itself (gold crowns have this advantage too).

2.PORCELAIN FUSED TO METAL (PFM)

A hybrid construction between all-metal and all-ceramic dental crowns type where a porcelain covering encases a metal substructure. These crowns can provide both good aesthetics and strength.

CERAMIC 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. The dentist or prosthodontist will remove a moderate amount of tooth structure, but it is very durable and strong.PFM's offer a long, tested track record.

Advantages:

  • They are strong

  • They are natural looking

Disadvantages:

  • The "dark line" phenomenon.
  • The metal that lies underneath the crown's porcelain surface can sometimes be seen as a dark line right at the crown's edge.

  • Achieving superior aesthetics can be a challenge.
  • While the appearance of a PFM crown can be excellent, it's often difficult to create one that's as natural-looking as the best all-ceramic ones.

  • Durability. It's possible for the porcelain surface of a PFM crown to chip or break off. 

3.ALL METAL CROWNS/GOLD CROWNS

These restorations are made using gold or "white" (silver-colored) dental alloy. They're known for their great strength and exceptional durability.

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 bio compatible with the gum tissue.

Base metal alloys contain non-noble metals which provide great strength to the crown and tooth and provide high resistance to corrosion. When preparing the tooth using base metal alloys, the dentist or prosthodontist would remove the least amount of healthy tooth structure. This material is resistant to wear and gentle to opposing teeth.

Advantages:

  • They are long lasting

  • They are kind to the neighbouring teeth

  • They are easy for a dentist to work with.
  • Dental alloys that have a high gold content are typically very workable metals. This factor makes it possible for the dentist to achieve a very precise crown-to-tooth fit.

Disadvantages:

  • They're not white like teeth.

  • Only disadvantage of metal dental crowns is their appearance. And for this reason, they're not usually placed on teeth that show prominently when the person smiles. They can, however, make a great choice for some molars.

ORAL CARE TIPS FOR BRIDGES & CROWNS

While crowns and bridges can last a lifetime, they do sometimes come loose or fall out. The most important step you can take to ensure the longevity of your crown is to practice good oral hygiene.

  • Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily

  • See your dentist or hygienist regularly for checkups and professional cleanings

  • To prevent damage to your new crown or bridge, avoid chewing hard foods, ice or other hard objects

WHAT IS A DENTAL CROWN?

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

WHAT IS A DENTAL BRIDGE? HOW DOES IT WORK?

Dental bridges literally bridge the gap created by one or more missing teeth. A bridge is made up of two or more crowns for the teeth on either side of the gap -- these two or more anchoring teeth are called abutment teeth -- and false-tooth/teeth in between.Dental bridges are supported by natural teeth or implants.

DIFFERENT TYPES OF DENTAL CROWNS AND DENTAL BRIDGES??

There are four different types of materials used for dental crowns and bridges:

  1. All ceramic (porcelain-based).

  2. Porcelain fused to metal.

  3. Gold alloys.

  4. Base metal alloys.
