Dental crowns made of porcelain fused to metal are stronger than all-ceramic versions and more appealing than those made of metal. However, their metal shell gives porcelain fused to metal crowns an unclear appearance. Because they lack the reflective quality of natural teeth, porcelain fused to metal crowns are not as discreet as all ceramic crowns. Additionally, over time, a thin metal band may be visible along the gum line with this type of crown. The crown’s porcelain portion can also chip or break off. This is a complete substitute. Ceramic crown looks exactly like natural teeth.
Dental crown materials that more closely match the light refraction index of a natural tooth will appear close to if not exactly like an adjacent natural tooth. This should be true in different light settings, meaning sun light, fluorescent and incandescent indoor light, as well as night club lighting. The all-ceramic crown is the best choice for achieving the most natural looking tooth replacement.
Occasionally a darker line will be visible at the edge of the crown, near to your gum when it recedes with age. One consideration in the ceramic crown is that these crowns may tend to show the underlying metal or gold margin at the gum line as gums recede over time. Some patients opt for this type of crown, but replace the crown at a later date in order to maintain a higher aesthetic benefit. Porcelain-fused-to-metal crowns with an all porcelain collar can eliminate this vulnerability. Ceramic Crowns maintain a translucency that makes them hard to tell from natural teeth. Without metal, the occasional problem of the dark blue line at the edge of the gums is eliminated. This can allow your dentist to place the edge of the crown above the gum line too, which can be healthier for your tooth and gums.
The main disadvantages of restoration with a ceramic crown are extensive irreversible tooth preparation (grinding away) and higher costs than for direct restorations such as amalgam or dental composite. The benefits include long-term durability and evidence-based success as compared to other restorations. The crowning of two fairly large molars to sling a bridge between them for a missing tooth is a costly and sometimes oversold procedure. The increased food and bacteria trapping of the underside of the bridge often offsets the benefits of the bridge element in maintaining the positions of the opposing teeth and the loss of the ease of use and mouth feel of two big natural teeth.
