Porcelain-fused-to-metal Crowns – Disadvantages of Porcelain-fused-to-metal Crowns

Porcelain crowns are dental crowns made of porcelain. Dentists recommend these crowns to people who have metal allergies. Porcelain crown provide the best natural color match when compared to any other dental crown. They are preferred for aesthetics reasons.

Dentist used to fuse a metal framework to create a crown strong enough to resist breaking. Due to technology development in dentistry since 1980s, dentists are able to bond the ceramic crowns directly to the teeth. These are called porcelain-fused-to-metal crowns.

Porcelain-fused-to-metal crowns are a kind of hybrid between metal crowns and porcelain crowns. They are especially chosen for front teeth. Although porcelain-fused-to-metal crowns are chosen for their excellent cosmetic appearance, there are some main disadvantages associated with the metal fused in them. Here are some of the disadvantages noted by users and dentists of these crowns:

    • When not mixed properly the porcelain in porcelain-fused-to-metal crowns can chip or break off.
    • Although the cosmetic appearance of porcelain fused metal crowns is excellent, they cannot be taken for granted. Sometimes they are not as pleasing aesthetically as all-porcelain crowns.
    • There are some cases where the surface of the crown creates wear on the teeth that it bites against. This were sometimes becomes so prominent that cannot be overseen.
    • The metal fused in the porcelain crowns are visible in some cases. They are seen as a dark line right at the crown’s edge. A dentist will try to position this edge to adjust it underneath the tooth’s gum line. But if the gums recede the dark line becomes visible. Thus it spoils over all appearance of the teeth.
