There are many different types of dental crowns. The most popular crowns used today in pediatric dentistry are those composed of stainless steel, polycarbonate, zirconia ceramic, composite strip, and resin-veneered. Continue reading to learn about each of these and the advantages associated with each.
Stainless Steel Dental Crowns
The dental crowns composed of stainless steel have been utilized in dentistry for nearly eight decades now. During the manufacturing process, the materials that are combined to create these crowns include iron, chromium, carbon, and those that are similar in nature. These metals combat the corrosion that may occur when the crowns come into contact with saliva.
These are commonly used on molar teeth due to the fact that they do not exhibit a natural tooth coloring. The advantages of having these types of crowns are that they are inexpensive, highly durable, east to trim, very easy to contour, and they may be put on the teeth quickly.
Polycarbonate Dental Crowns
These dental crowns are created with polycarbonate resin casings and are cemented to the tooth using self-adhesive resin product. These crowns do have the same coloring as the natural teeth. Unfortunately, due to their lack of strong durability, they are mostly only used for restorations that are temporary.
The advantage to polycarbonate pediatric dental crowns is that they are relatively inexpensive and that offered improved aesthetics.
Zirconia Ceramic Dental Crowns
These dental crowns are created using zirconium oxide, which is enhanced by yttrium oxide. Many makes may contain porcelain. While they have a very high level of durability and look absolutely beautiful in the mouth, they are not able to be contoured and they cost a lot of money.
Most pediatric dentists will not opt for this type of dental crown due to the operatory time that is required to place the pieces in the mouth. Plus, most would advise waiting until adulthood for these.
Composite Strip Dental Crowns
Composite strip dental crowns are moderately-priced, but provide excellent beauty to the mouth. These are placed through a hardening type of composite material and a clear mold. Unfortunately, they are prone to breakage. Placement and moisture control are critical to the overall success of these dental crowns.
Resin-Veneer Dental Crowns
These types of dental crowns combine stainless steel with resin covering. In order to place them, though, the tooth must be removed. This is due to the limitations in terms of crimping to shape them. While considered to be the most expensive among dental crowns, they are exceptionally strong and look much like the natural tooth.
There are many reasons why a child may require dental crowns. These include saving a tooth that has been impacted by tooth decay, protecting the tooth, and improving the general appearance of a tooth.
