Tooth Reshaping with Sinsa Veneers and All-Ceramic Crowns

By Park Jonguk, DDS, MS — board-certified specialist in conservative dentistry Published

Hello. I'm Park Jonguk, head of Dream Dental Clinic.

When retreating an old all-ceramic crown on a front tooth,

there are cases where the other teeth are also treated with Sinsa veneers at the same time.

Or a tooth may have had root canal treatment, or discoloration

or severe decay means an all-ceramic crown is needed,

while veneer treatment is done on the other teeth

at the same time, to reduce how much they need to be cut down.

In cases like this, the hardest part is matching the color.

Because the type of ceramic used for the crown and for the veneer is different,

matching the colors of these different types of ceramic is a fairly tricky process.

Occasionally, one old Sinsa veneer comes off,

and even in a case of retreatment,

matching the color to the other remaining veneers is quite tricky.

In many cases, the easy way to handle this

is to make every tooth opaque.

If everything is made uniformly white and opaque,

it's very convenient from the dentist's point of view.

But even so, I don't treat patients with teeth that end up white, opaque, and unnatural-looking.

There's one all-ceramic crown that was finished well a long time ago.

If I didn't tell you, you probably wouldn't be able to tell which tooth it is.

That tooth wasn't the problem —

rather, the surfaces of the other teeth had chipped little by little,

the alignment had shifted somewhat, and to make the teeth overall more even and attractive,

we decided on retreatment of the all-ceramic crown along with Sinsa veneer treatment.

This tooth is the all-ceramic crown.

From the alignment to the color and shape of the teeth,

a plan is developed to make everything more attractive.

The treatment plan ends up being developed in two possible ways.

One is no-prep veneers for the remaining teeth aside from the crown,

and the other is minimal-reduction veneers.

These are the two options considered.

If no-prep veneers are used,

it's good that there's no damage to the tooth,

but the downside is that the tooth becomes considerably larger than it is now,

and the front teeth end up wider from side to side.

Since this is a treatment meant to make things look nice, having the teeth end up bigger and looking bulkier isn't ideal.

So we decided to go with minimal-reduction veneers,

and proceeded with tooth reduction, removal of the all-ceramic crown, and fabrication of temporary teeth.

After removing the all-ceramic crown,

we could see that the tooth had already been reduced quite substantially.

For the remaining teeth, aside from that one,

only the front teeth and canines were minimally reduced,

and the lateral incisors were treated with no reduction at all.

As mentioned earlier,

because the materials are different, it's quite difficult to get the crown and the Sinsa veneer to match in color.

In a case like this,

the teeth are placed in the mouth,

and the tooth color has to be adjusted repeatedly until it matches.

This case was handled the same way,

discussing it together with the patient

as we worked to match the tooth color.

Sinsa veneers can't be temporarily bonded,

but since a crown can be temporarily bonded,

it was worn for about a week to check whether the color looked right under a variety of lighting conditions.

Even viewed from various angles,

both the tooth color and shape are in good harmony.

This is how we brought such a tricky color match to a natural-looking finish.

Comparing the before-and-after photos, you can clearly see teeth that are more even, more attractive, and brighter.
