|Authentic Press To Metal PTM
Authentic Press-To-Metal is the best of both worlds incorporating
strength and beauty! The resulting restoration presents the esthetic
subtlety that can only be achieved using the broad palette of
pressable materials and the functional durability of a cast substructure
with multiple units. This technique automatically provides a full
360¡ë ceramic margin. An Authentic Press-To-Metal crown is cementable,
exhibits low wear and is completely bio-compatible.

Letter of reference
I have written this note to help other Dentists discover
a better style of crown.
I have been using a metal core with a pressed ceramic and
porcelain covering from New Zealand Dental Laboratories.
There are several marked advantages to this modality.
The crown has a 360¡ë porcelain margin, so there is no metal
As the ceramic is pressed, the margins are waxed up, and
what you wax, is what you get,i.e. No shrinkage away from
margin on firing. The margins are truly way superior than
any traditional vmk can give.
The colours of the ceramic blocks are excellent too, and
the low fusing porcelain is easier to adjust and polish.
I have used them for all my crowns since discovering them,
and also for bridge units.
I have had no failures and the superior margins will surely
mean they will be less likely to leak, and therefore last
longer. I would not do a traditional vmk now.
