Yellow Gold Full Cast Metal Crown High Casting Accuracy ISO13485

Advantages                                                                                                                                         

Considerations.

• Keeping in mind how many decades a person's teeth might be in perpetual contact with the crown opposing them, this might be a significant point to consider. Especially in the case where they have a habit of clenching or grinding their teeth.
• In comparison to all-metals, porcelain-surface crowns that have not been polished or glazed appropriately (a failure on your dentist's part) are likely to cause tooth wear, possibly significantly so.

  Beyond that, due to the wide range of ceramics that can be used to make tooth-colored crowns, no other hard and fast rules can be stated. Studies do suggest however that some types of ceramics are kinder or gentler to opposing dentition than others, possibly on the same order as high-noble dental alloys. (Yin 2004)

Hypoallergenic

While possible, it's relatively rare for a person to have an allergic sensitivity to a crown that's been made using a "gold" (high-noble) dental alloy. This same statement cannot be made for base-metal ones (see below).

Considerations.

In cases where potential complications with a metal allergy are a concern, placing an all-ceramic dental crown can sidestep this issue entirely.

 Less tooth reduction is required.

When preparing (trimming) a tooth for dental crown placement, comparatively less tooth reduction is needed for an all-metal as opposed to a porcelain-fused-to metal or (almost all types of) all-ceramic crowns.

That's because crown strength is the only consideration involved. And since dental alloys are so strong, only about 1.5 mm of thickness is required (about the same thickness as a penny). In comparison, most porcelain-surface crowns require 2 mm or more.

Disadvantages                                                                                                                     

Their shiny metallic appearance.

The single disadvantage of an all-metal is the obvious. It simply doesn't look white like a tooth.

If that were not the case, in the vast majority of cases choosing a "gold" (high-noble alloy) crown would make the very best choice.
