Lee, Bonfiglio, Vesely & Associates, has been named one of the Top Dentists in Annapolis. We offer a full range of general and cosmetic dentistry services. Our dentists provide several treatment options for dental crowns. They can be used for a number of reasons including:
Our cosmetic dentists can also use dental crowns to replace old, worn and unsightly restorations like metal fillings or metal caps. In some cases, your dental crown procedure can be performed in a single visit using CAD/CAM technology.
Types of Dental Crowns
There are generally three types of dental crowns - those made of gold, all-ceramic and ceramic-veneered gold crowns. In our Annapolis dental office, we often recommend tooth colored crowns, those that are all-ceramic or metal-ceramic crowns for the most aesthetic restorations. All gold tooth crowns or metal-ceramic crowns are usually used on teeth in the back of the mouth where the forces from chewing and grinding are most prevalent.
Crowns Made of Gold
Gold crowns are used when appearance is not a priority to you. The gold is extremely workable, making gold crowns a more precise fit than any other type. While a slight possibility of chipping exists with porcelain crowns, gold crowns provide no such problem.
Types of Porcelain used with Dental Crowns
There are basically two types of porcelain used in dental caps and crowns, these are feldspathic and pressed ceramic porcelains. The feldspathic type is the original method that has been around for 20 years. A ceramist in a dental lab bakes porcelain onto thin high noble alloy shell and then heats it in an oven. The ceramist is able to create tints and opaques inside the porcelain of the dental cap or crown to give the natural look we seek.
Pressed ceramic is created from a single ingot. The ingot is melted and pressed in one piece to create the desired shape of the cap or crown. The stains and opaques are applied only to the surface of the porcelain to give a natural look for your new smile.
Resin and Porcelain - Crowns and Onlays
The new reinforced resin or bonded all-porcelain type of cap has the nicest appearance in cosmetic dentistry. This cap can be made from pure ceramic or a new reinforced composite resin. It is almost indistinguishable from natural teeth. The new bonding technology involved provides an exceptional bond your tooth. It is metal-free, and thus satisfies the needs of patients with metal sensitivities.
When correcting your back teeth with bonding, the cosmetic dentist will perform a tooth colored onlay. This type of procedure is used to correct only the parts of your tooth that are in need. This procedure is metal-free.
Porcelain and Metal Crowns
For a very natural appearance, porcelain fused to metal crowns are the answer for you. However, they have a metal substructure and require an opaque below the porcelain, which can make the translucency of natural teeth difficult to match. Sometimes a darker line will be visible at the edge of the cap, near to your gum when your gum recedes with age.
Types of Porcelain Used in Creating Crowns
In our Annapolis dental office, we provide Empress, Lava and Procera all-ceramic crown systems, as well as computer aided all-ceramic designed crowns.
Feldspathic porcelain is the standard, traditional porcelain that is used for crowns. Many cosmetic dentists feel that this is the most beautiful porcelain.
Empress, strictly speaking, is not a porcelain, but more like a glass. Empress can be called a ceramic material. The Empress material is cast rather than baked as a feldspathic porcelain crown is. The fit of Empress is more precise than the baked feldspathic porcelain. However, the color in Empress is mostly baked on the outside. Empress can be very beautiful. For appearance's sake, some expert cosmetic dentists prefer the feldspathic porcelain, and some prefer the Empress.
Lava Zirconia is a milled ceramic on the inside with a more traditional porcelain baked onto the outside. The advantage of Lava is its exceptional strength. However, the milled ceramic core is opaque white, so many cosmetic dentists feel that it isn't as natural-looking as the more translucent materials. An advantage of Lava is that it doesn't have to be bonded to the tooth but can be cemented with ordinary crown and bridge cement, a technique familiar to all dentists.
Procera is similar to Lava, but the milled ceramic on the inside is a more translucentalumina, rather than an opaque white material. The alumina is shaded, and then the final esthetics of the crown are achieved in the baked-on outer layer. The procera crown can also be cemented with traditional techniques. However, any crown cemented with a traditional crown and bridge cement is going to be susceptible to a compromise in the appearance if that cement line ever shows.
Frequently Asked Questions
Are all ceramic crowns the best choice for me?
Porcelain fused to gold offers a great cosmetic option for rear molars when strength of the restoration is a concern. We offer several Dental Crowns and Caps restorative options. We will help you decide which system is the most appropriate to achieve the strongest and the most natural looking crowns for your smile.
How long do dental crowns last?
Our dental restorations are designed to last for several decades. Numerous factors will determine the longevity of your restoration - including: type of material, location of the restoration and lifestyle habits (smoking, stress, etc). We will discuss with you what kind of results you can expect based on your needs and goals.
Are tooth crowns covered by insurance?
Unfortunately, dental insurance does very little to cover a high standard of care. Coverage for tooth crowns varies from one insurance company to another and even from one plan to another. In general, the insurance company will provide some allowance for dental crowns, though it may not cover the full cost of your treatment. Our office staff will help you with all the billing and insurance paperwork. We also offer financing options for patients who want to set up a payment plan.
