Crown & Bridge

Crown is a fixed dental prosthesis used to restore a damaged tooth or cover an implant. It resembles the lost, damaged or missing tooth and helps in restoring its shape, size and function. Bridges on other hand are fixed dental prosthesis used to replace one or more missing teeth by joining fabricated teeth with adjacent teeth or implant.

A dental crown may be required to protect a weak tooth from breakage, to restore an already broken tooth, to cover and support a tooth with a large filling, to cover misshaped or severely discoloured teeth, to cover severely attrited tooth, to cover a dental implant or to make a cosmetic modification.

Following are the different types of dental crowns:

 Stainless Steel crowns: These crowns are generally used as permanent crowns in children. These crowns are ideal for restorations in children as they are prefabricated and don’t require multiple visits to the dentists. They are cost effective and usually come off along with primary teeth as they shed off to make space for permanent teeth in the oral cavity. Stainless steel crowns are often used as temporary crowns in adults, till customized crowns are fabricated.

 Metal Crowns: These are generally made from alloys that are noble or base-metal alloys. Metal crowns are ideal choice for restoring molars as they can resist biting and chewing forces, and don’t break or chip off easily. Since they aren’t tooth coloured crowns, they cannot be used to restore front teeth. In our practice we consider these crowns as out-dated.

 Porcelain-fused-to-metal Crowns: PFM crowns provide best of both the worlds. They have metal’s strength and porcelain’s aesthetics. After all ceramic, PFM crowns are the second best in terms of providing natural tooth like colour. However, porcelain part of the crown does tend to chip off if subjected to heavy masticatory forces. Sometimes the metal lying underneath such crowns can be seen as dark line especially near the gum margin. So in our practice we use these crowns for back teeth restoration.

Emax crowns: These crowns are strong as well has natural tooth like appearance due to light transmitting quality. They are the latest cosmetic porcelain. Emax crowns are highly aesthetic and are therefore used for front teeth restorations.

Empress Crowns: Empress Crowns provide utmost aesthetics due to its close resemblance to natural teeth. However these cannot be used to restore back teeth which are subjected to high occlusal forces due to less strength of material.

 Feldspathic Crowns: These crowns are believed to be the most beautiful porcelain crowns. However these are technique sensitive and are used by only by skilled dentists and laboratory technicians.

 Procera Crowns: Procera is an all-ceramic restoration that has successfully taken metal out of the mix in the production of dental crowns. They are made with an aluminium oxide as base coping that is custom milled with CAD technology and a superficial stacked translucent porcelain layer that is used to make the restoration attractive and lifelike. They are biocompatible and its tissue-friendly material encourages gums to grow back around the tooth. It can be used for front as well as back teeth restorations of crown and bridges.

 Zirconium Crowns:  Zirconium crown is a CAD CAM milled all-ceramic crown that are mainly used for front and back teeth crown and bridges and as implant abutments. It has zirconia as substructure and porcelain stacked on it for optimum aesthetics. There are many brands of this product and some have higher clinical success rates. Some of these are 3M Lava, Cerec, Bruxzir, etc.
