Crown and Bridges
There are different types of crowns that vary depending on materials, cost, and procedures, Before looking into the different types of dental crowns and cost, how can you know for sure if you need a crown, an inlay, an onlay, or just a filling?
After a thorough examination, your dentist at Kamala dental will evaluate your particular case, and guide you on the possible treatment options. Some of the most common causes for attaining a dental crown are:
When you need a custom-made crown, be ready to visit your dentist a couple of times. It is not something a dentist can do in just one appointment, unless he or she owns a CEREC® milling machine or similar devices, which allows patients to obtain the crown in a single visit.
Steps in fabrication of a dental crown
Types of Crowns
Metals used in crowns include alloys that have a high content of gold or platinum, or base-metal alloys (for example, cobalt- chromium and nickel-chromium alloys). Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color and the lack of marginal fit around the natural tooth are the major drawback if such metal crowns.
Porcelain-fused-to-metal dental crowns (PFM) are somewhat of a hybrid between metal and porcelain crowns. When they are fabricated, the dental technician first makes a shell of metal that fits over the tooth. A veneering of porcelain is then fused to this metal (in a high-heat ceramic furnace), giving the crown a white tooth-like appearance.
The metal that lies underneath the crown’s porcelain can sometimes be visualized as a dark line found at the crown’s edge .We usually try to position this dark edge just underneath the tooth’s gum line. But, if the gums happen to recede, or if it is very thin, the dark/ metallic line can show, thus ruining the crown’s appearance.
Metal Free Ceramic Crowns
Due to their life-like translucency, all Ceramic / metal free Ceramic crowns can be the most cosmetically pleasing of all the different types of dental crowns. For this reason, they often make an excellent choice for restoring front teeth. They are a biocompatible alternative for people suffering from metal allergies.
Our conventional PFM (Porcelain Fused to Metal) crowns do have an 85-90 percentage natural appearance and are highly enduring. However, being coated over metal, ceramic will not show the same optical properties as that of a natural tooth.
At Kamala Dental Specialty Hospital we offer you better alternative instead of your bulky PFM crowns having metallic margins to, aesthetic or life-like Metal Free Crowns.
Lithium Disilicate Crowns
It is a type of all-ceramic crown, which is made of lithium disilicate- a material that is Light, thin and translucent having the commonly known brand name, E-Max.
Zirconium is a relatively new material that combines the strength of metal with the aesthetics of porcelain crowns. High translucent zirconia and layered zirconia crowns have become a more popular choice today. They are layered with glass ceramics for better aesthetics.
Full Contour Zirconia Crowns – High Strength
They are non-layered single block milled zirconia crowns. Full-Strength Zirconia / High strength (1200 Mpa Flexural strength) are used for the most functionally demanding cases. One of the brand Brux-Zir have proven to be long lasting in bruxers and clenchers – thus proving to be an aesthetic alternative to cast gold and metal occlusal PFMs.
