[Saving Teeth] The Crowned Tooth Broke. Trying to Use My Own Tooth to the Very End Through Orthodontic Extrusion

Hello.

I’m Dr. Junhee Jeon, the dentist who protects teeth in Sinchon.

I am a specialist in conservative dentistry.

Diagnosing and solving various problems that occur in natural teeth is my main work.

I often meet patients with different stories from all over the country.

Today’s story is about a man in his 30s.

For a man in his 30s, when social life is at its most active, one day, his two front teeth disappeared.

How bewildering must that have been?

These were teeth that had previously undergone root canal treatment and been covered with crowns,

but one day, all of a sudden, as if they had agreed on it, both crowns snapped and broke off.

In a situation like this, the option is orthodontic extrusion.

What is often compared with orthodontic extrusion is surgical extrusion.

Surgical extrusion is a procedure in which the tooth is intentionally extracted and then repositioned to the desired location.

It is faster than orthodontic extrusion.

You may ask why I did not recommend the faster method for a patient in his 30s who needed to return to daily life quickly.

The reason is that those teeth had already undergone root canal treatment.

Teeth that have had root canal treatment become brittle over time. When extracted, the roots often crumble and break apart.

If we had attempted surgical extrusion too aggressively, there was a possibility that we would have had to say goodbye to the tooth forever.

Before performing orthodontic/surgical extrusion, a careful examination of the tooth condition is necessary.

• There should be no severe tooth inflammation.
• The root length must be sufficiently long so that, even after pushing the tooth upward, enough length remains to support the entire tooth within the bone.

Only when these two conditions are met can extrusion be attempted.

An elastic band is connected to the tooth to be brought out.

Heave-ho! Heave-ho!

About two weeks have passed since orthodontic force was applied.

Like a sprout emerging, about 1–2 mm had started to come out.

The first step is difficult, but once it starts coming out, it comes out easily.

About two months have passed since treatment began.

The desired amount of tooth structure had already been secured.

To fix the tooth in its new position, the patient returned after a retention period*.

• To allow the tooth to stabilize in its new position, a period of simply watching and waiting is necessary.

A new root canal treatment was performed, and a ceramic post was also placed to firmly support the root and crown.

And finally, a crown was made.

While making the new crown, we also addressed the tooth height asymmetry that had been bothering him.

Congratulations on your new, beautiful, and strong tooth.

If you pay attention to oral hygiene so that cavities do not develop, I think you will be able to use it for a long time^^
