Empress 2 pressure ceramic crown

Empress 2 pressure-ceramic crown

This is the end result, and as it is visible, we had succesfully put the front teeth into the same curve and had standardised their colour. The work process: in the first phase we do the grinding, creating the imprint and the temporary cover. In about 3-4 days we test the raw ceramics which allows the patient to request changes in the colour of the ceramics and the shape, length and width of the teeth. In the last phase (usually 1-2 days after the trial) we bond in the finalised crowns/veneers.

This patient came to see us because of his teeth with bad aesthetics, he wanted to have them whiter and more natural. Teeth whitening was not an option as the discolouration was caused by medication, this why we chose to use veneers instead. There was already an unfitting crown on the upper left first tooth, what we decided to change in conjunction with creating the veneers. The next time we did the grinding. We have created a crown to his upper right first tooth as the veneer wouldn’t have been a safe solution because of a big filling, but veneers were the ideal choice for the rest of his front teeth.

Full ceramic crown, the only difference from Noritake crown is its material. The stump needs to be shoulder-prepared as well, its aesthetics is also beautiful, and it suits the front teeth the best as well. Bridge can be also made of it, only to replace one tooth (so the bridge is made of three partials). It’s harder than the Noritake crown and its production is different as these kind of ceramics are pressed on high pressure while calcinations. The hardness of Empress 2 pressure-ceramic crown is due to this technique. Through the preparation, 0.7-1mm tooth material needs to be removed from the surface of the tooth (as the molecules of this ceramic are larger and thicker). Empress is more resistant to fracture, it is recommended to those with stronger bite (although it isn’t completely safe when someone has a very powerful bite). It is possible to create pressed-ceramic crown onto a root canal treated tooth: it covers the discoloured stump (if it is not too discoloured) and it is very aesthetical due to its high fibre contents, there is no obvious grey edge, and no metal allergy occurs. The Empress 2 pressure-ceramic crown is slightly harder than the natural tooth enamel, therefore more difficult to break, but it wears out the opposite teeth a bit more. Another advantage of the Empress crown that its life-span is very-long and it’s crack-free (it is recommended to those doing martial arts if using adequate teeth protectors). The comparison table of metal free ceramic crowns is available at the reception.
