I’m Dr. Park Jeong-gi of Remember.
After esthetic prosthetic treatment
a long time has passed,
it is not uncommon for cracks to form
or for pieces to break.
When the restoration withstands strong chewing forces
until it reaches its limit and breaks,
or even when the material is hard,
it can still wear down, abrade,
and eventually fracture.
The textbook lifespan of a prosthetic restoration
is generally known to be about 7 to 8 years,
and depending on how oral care is managed,
there may be some variation.
Today at Seoul National University Entrance Dental Clinic,
among various treatment items,
I’ll explain information related to laminates.
First, to briefly explain what a laminate is,
it refers to an esthetic prosthetic treatment
that improves the color or shape of teeth
by minimally reducing the tooth surface
and bonding a thin ceramic material to it.
Because it has the advantage of creating a beautiful smile
while minimizing damage to the natural tooth,
many people choose this method,
and these days, with growing interest in beauty,
it is one of the more popular treatment options.
Looking at the photo shown at Seoul National University Entrance Dental Clinic:

There are previously restored laminates
on both maxillary lateral incisors,
and a vertical crack with a fracture line
is observed.
The lateral incisors are the teeth located right next to the central incisors,
even among the front teeth,
and because they are highly visible when smiling,
they are very important esthetically.
So why does a laminate break?
There can be several causes,
including:
- excessive bite force or bruxism
- a habit of frequently eating hard foods
- the habit of biting chopsticks or forks
- traumatic occlusion
- strong impact from an accident or a fall
These are considered the main causes.
Also, during the initial fabrication,
if occlusal adjustment was not done properly
or there was a problem in the bonding process,
a fracture may appear over time.
How can a broken laminate already in place
be addressed?
Unfortunately, a fractured prosthesis
cannot be reattached and reused.
At that point, the damaged existing restoration must be
carefully removed,
then a new impression is taken and a new restoration is fabricated,
so that the tooth can be protected through replacement.
For this case, Seoul National University Entrance Dental Clinic
used an esthetic prosthetic called
'RealNate.'
As the name suggests, RealNate conveys the meaning of a real(real)-like laminate,
with colors so refined that it is difficult to distinguish from natural teeth,
and it boasts excellent detail in shape, size,
contour, and translucency.

Looking at the completed restoration of both lateral incisors
with RealNate at Seoul National University Entrance Dental Clinic,
it is not simply a replacement for the fractured part;
because the shade was determined by closely analyzing
the tones of the central incisors and canines,
it looks very natural.
In addition, because the height was adjusted carefully,
taking into account the incisal edge, that is, the length of the tooth tip,
it can be seen that it harmonizes with the surrounding teeth.
Matching color harmony and length balance like this
is truly the key to natural-looking esthetic treatment
that does not stand out.
There is no need to feel discouraged or worried
even if a laminate or prosthetic restoration fractures.
It may even lead to a more satisfying result than before,
and since it happened because the time for replacement may have come,
you may feel more at ease if you think of it that way.
Esthetic treatment
is not simply about making teeth white and pretty;
it is a delicate treatment that pursues naturalness and harmony.
At Seoul National University Entrance Dental Clinic,
we will always be open to helping you regain a bright smile
through RealNate.
