Comparing Different Types of Crowns

Posted By The Szikman Dental Group, P.C. || 27-May-2014

Dental crowns have been around since ancient times, but the composition of them have come a long way over the ages. Today, there are three most common types of crowns performed: all-porcelain, porcelain-fused-to-metal, and gold.

Before the modern technology in the industry developed, crowns were most often fashioned out of gold. Gold is a very malleable metal, and it holds up well and lasts a long time. Even today, some patients prefer to have gold crowns done rather than the more aesthetic porcelain because of how long gold crowns can last. Gold does not break, true. However, over a long period of time, gold can wear down and may require replacement. Unlike the one-visit CEREC all-porcelain crowns, gold crowns require two visits to complete. The first visit, the tooth is prepared and an impression is taken and sent to a dental laboratory for fabrication of the gold crown. Approximately two weeks later, the patient returns to the dental office for the cementation of the gold crown. Another drawback of gold crowns is that they appear in the mouth as a gold metal, not like the white enamel of your natural teeth. And finally, because the price of gold has increased, sometimes these type of crowns can be more expensive.

Porcelain-fused-to-metal crowns were the industry standard before all-ceramic crowns were introduced to the market largely 20 years ago. A PFM crown has a metal base and the visible portion of the crown is made of porcelain fabricated to match the patient’s existing tooth shade. Like gold crowns, these also take two visits and require a dental laboratory to make them. However, they look natural in the mouth and are ever so slightly stronger than the all-porcelain crowns.

CAD-CAM dentistry has allowed dental offices to create beautiful, aesthetic and functional all-porcelain crowns in one visit, right in the office. An all-porcelain crown has no metal and the impression that is taken is digital, not with the usual impression material that requires you to bite down until it hardens. There is no metal at all, so the result is beautiful and natural and looks exactly like your own tooth. All ceramic crowns have been known to break; however, with the updated technology, better cements and primers, and stronger all-porcelain materials, the percent of breakage is decreasing.

At The Szikman Dental Group, P.C. in Atlanta, we perform all three types of crowns for our patients. The overwhelming majority of our patients prefer the one-visit CEREC all-porcelain crowns due to the natural appearance, convenience of a single visit, and the fact that no metal is present.
