Precious Ultra-hard High Noble White Gold types of Dental Implant
There's no more natural-looking type of crown.
Due to the life-like translucency of the materials from which
they're made, all-ceramics can be the most aesthetically pleasing
of all of the different types of dental crowns. And for this
reason, they often make an excellent choice for restoring front
Not all all-ceramics can make this claim.
It's important to know that some types of all-ceramic crowns are
much better than others in their ability to closely mimic the look
and luster of natural teeth. This is due to both the type of
ceramic and fabrication method used in their construction.
- At one end of the spectrum lies those crowns whose full thickness
has been crafted by hand by combining multiple layers of porcelain.
Since each one can be different in terms of shade or level of
translucency, the restoration can be given a very life-like
appearance. (Unfortunately, due to both the technique involved and
the materials used, these types of crowns are comparatively
- At the other end of the range lies those crowns milled from a
single homogeneous cube of ceramic. In this case, the result is one
where the restoration just has one uniform color. And that means it
really can't mimic the normal shade and translucency variations
found in natural teeth.
As a compromise, nowadays all-ceramics for front teeth are
typically constructed in a fashion where those portions of the
crown that aren't readily visible are premade (milled, pressed or
cast), using ceramics that are generally less natural-looking but
have better physical properties. The front surface of the
restoration is then crafted by hand, by adding on individual layers
Doing things this way provides a way where the crown can be given
great characterization, and also better mechanical properties (such
as greater strength). But you can't just assume that this is the
way the crown for your front tooth will be constructed. You
absolutely have to ask.
Concerns about strength and longevity.
Generally speaking, porcelain-fused-to-metal and especially
all-metal crowns can be considered to be stronger types of
That means in the back of the mouth where substantial chewing
forces are routinely generated, placing an all-ceramic might not
make the best choice. (Your dentist's judgment will be required on
In the front of the mouth, crown strength is less of an issue and
easily out weighed by the superior aesthetics that an all-ceramic
restoration can typically provide.
