Complete porcelain "JACKET" crowns – solutions true to life
Complete porcelain crowns are the innovations of modern aesthetic dentistry. In opposition to traditional crowns, which contain a metal frame, the complete porcelain crowns do not contain metal at all.
Porcelain crowns are also somewhat weaker, because they lack the metal frame, but all the more beautiful aesthetically. Light passes through the layers of the porcelain freely, it does not meet and obstacle, which decreased the transparency of traditional crowns.
Since crowns containing metal frame are a bit more vulnerable, they are only recommended for the area of incisors, because they are not suitable to bear the increased burden in the chewing area.
Complete porcelain crown – advantages and disadvantages:
| advantages | disadvantages |
|---|---|
| perfect aesthetic effect | only solo crown can be made |
| a perfect replica of the own natural tooth enamel can be prepared | more vulnerable, because it has no frame |
| no grey margin of gum | not recommended for sportsmen |
| no metal allergy | shorter life span |
Preparing the stump under complete porcelain crowns is only possible with shoulder-crown preparation technique. The established shoulder margin provides the surface suitable for the margin of the crown to lean against. Thanks to the shoulder preparation, gum tissue around teeth like this remains protected, intact and healthy.
