Hello.

I am the director of Seoul Bardi Dental Clinic.

Some people end up with only the root remaining after a tooth breaks or becomes severely decayed.

Because it does not hurt much right away, or because they are afraid of dental treatment, they often leave it untreated.

Do you know why it is dangerous to leave a tooth with only the root remaining?

Today, along with the risks, we will introduce a case of a patient whose overall dental health was restored.

Reasons why it is dangerous to leave a tooth with only the root remaining Why is it dangerous to leave a tooth with only the root remaining? A full implant reconstruction case in Godeok-dong

If the crown is gone and only the root remains, the inside has already become a pathway for bacteria.

Why can’t you just leave it as it is?

First, inflammation develops at the root tip and dissolves the surrounding jawbone.

Even if you later want to get an implant, treatment may become difficult because there is no bone left to place it in.

Second, it can damage the surrounding teeth as well.

Inflammation tends to spread sideways,

and as the teeth lean toward the side with only the root remaining, the overall alignment collapses.

  1. Patient case: a situation requiring full reconstruction Why is it dangerous to leave a tooth with only the root remaining? A full implant reconstruction case in Godeok-dong

A patient who recently visited our clinic was in quite a serious condition.

The lower jaw had long since lost both back molars,

and most of the upper teeth were barely hanging on by the roots.

After examining the panoramic X-ray and CT, we found extensive inflammation at the root tips.

We decided to keep only the two upper teeth that were the strongest and could still be used (#14, 27), and unfortunately extracted the rest.

The lower front teeth had lost a lot of jawbone and were loose, so we decided to extract a total of four teeth.

Fortunately, the front teeth that could be saved had severe wear, but the roots were still in good condition,

so after root canal treatment, we planned a bridge treatment linking a total of six teeth.

When there are almost no teeth left, you should not have to go without eating while waiting for the implants to settle.

So we first made a temporary denture that could be used immediately after extraction.

<Treatment plan>

Maxilla: 8 implants placed Sinus lift and bone grafting

Mandible: 5 implants placed Lower front tooth bridge and molar crown (#44)

  1. Why can navigation implants be more reassuring? Why is it dangerous to leave a tooth with only the root remaining? A full implant reconstruction case in Godeok-dong

For full-mouth implant treatment, where comprehensive placement is needed, accuracy is everything.

Since it is a major surgery involving the placement of many implants, you may feel worried first.

Don’t worry.

We perform surgery more safely and precisely through navigation implants.

What are the advantages of navigation implants?

  1. We practice digitally in advance.

Before surgery, we digitally map out the patient’s jawbone in 3D on a computer.

We check in advance where the dangerous nerves are,

and find the safest path through a virtual trial placement.

  1. Less gum incision means less pain.

Because we already know the exact position, there is no need to widely open the gums.

We can place the implant through a small hole only where it is needed, so there is less bleeding,

and the swelling and pain experienced after surgery are noticeably reduced.

  1. The more implants there are, the more important precision becomes.

For patients who need many implants, even a slight angle difference can make the prosthesis uncomfortable later.

The digital guide pinpoints the designated position, so it can be firmly placed without error.

3 months later

For three months after surgery, we waited for the implant posts and jawbone to harden firmly.

Fortunately, the bone graft sites settled well, and after confirming that the implants were fixed very firmly, we placed the prosthetics.

Now, instead of the teeth that had only roots remaining, the patient can comfortably eat with strong teeth.^^

Are you still leaving teeth with only the root remaining untreated?

If it gets any later, the treatment process can become several times more difficult and complicated.

Before things get worse, why not get an accurate diagnosis?

We do not insist on implants in every case.

Depending on your oral condition, a bridge may be better, or an implant may be more advantageous.

We will find the most honest and optimized plan for your condition.

If you are 고민 중이시라면, please visit us anytime.

Thank you.^^
