Revealing a Delayed Placement Method for Safely Placing Implants When They Are Close to a Nerve

Hello,

I’m Lee Juri, head doctor at Seoul Bardi Dental Clinic.

Implants may look as if they are placed anywhere,

but they are inserted in a highly calculated space

while avoiding the nerve canal

and ensuring there is enough bone.

Today, I’ll share information related to the inferior alveolar nerve canal, which you should be careful about when placing lower molar implants.

I previously wrote a post so that you could learn properly about implants before getting them.

There are areas that require caution when placing implants.

A representative example is that upper molars must be placed without tearing the maxillary sinus membrane,

and lower molars must be placed while avoiding the inferior alveolar nerve canal.

The inferior alveolar nerve canal

may be familiar to those who have had a lower wisdom tooth extracted.

It is the passage through which the important nerve responsible for sensation in the lower lip, chin, and teeth runs.

If an implant is placed incorrectly and touches the nerve canal, complications such as numbness or pain may occur.

You may keep feeling as if the anesthesia around your lips has not worn off,

and you may not notice if rice grains or ice cream get on you.

The location of this nerve canal varies slightly from person to person,

and some people have an especially short distance between the jawbone and the nerve canal.

If inflammation at a tooth root is left untreated for a long time,

the surrounding bone can become extensively resorbed.

Because the distance to the nerve canal is too short and there is a risk of injury during surgery,

a short implant may be chosen,

or the implant may be placed after waiting for the bone to fill in.

2. The process of delayed placement after extraction

The tooth is loose A patient visited with a complaint of tooth mobility

230407

It looked fine on the outside,

but when we tested it, the tooth was severely loose.

As the last molar bore a lot of chewing force,

the resorption of the jawbone was observed on the X-ray.

Since it is at the very back, the toothbrush does not reach it well,

so poor brushing likely also played a role in the bone loss.

230407

According to the CT scan results, the distance between the inferior alveolar nerve canal and the alveolar bone was very short.

If we wanted to shorten the treatment period, it would have been ideal to place the implant immediately on the day of extraction...

but there was a possibility of nerve damage.

230407

We first performed the extraction,

removed the inflammation at the root tip thoroughly,

and planned to place the implant after a few months, once the bone had recovered to some extent.

If inflammation remains, the bone does not fill in well, and it can also affect the success rate of the implant,

so this process of extracting the tooth and thoroughly removing the inflammation is the most important part.

We gave enough healing time and waited for the bone to recover.

After the extraction site had recovered to some extent, we measured the distance to the nerve canal again.

Without choosing a short implant,

we were able to secure sufficient depth and placed the implant.

Beforehand, using the navigation implant surgical method, we calculated the distance to the nerve canal

and were able to reduce the risk of nerve damage.

I was worried about nerve damage, but it seems it went safely, so I’m relieved.

With the patient’s feedback as the final note,

treatment was completed.

When the nerve is nearby, caution is needed only during implant placement,

and the crown is worked on above the already placed implant,

so the procedure went forward without major difficulty.

If the nerve canal is close, trying to place the implant immediately can instead bring a greater risk.

Once a nerve is damaged, recovery is difficult.

You may need to take medication for a long time..

and there is no guarantee that it will return to normal 100%.

241015 Completed implant

You can speak and eat without difficulty,

but if the sensation you used to feel disappears,

it will be very uncomfortable.

Placing even one implant

is not necessarily easy.

(Each step is important and requires focus.)

In cases like this, where the inferior alveolar nerve canal is close,

safe implant placement becomes the top priority

so that nerve damage does not occur.

One of the methods that allows safe placement is delayed placement.

Placing a short implant can also be an option,

and navigation is another alternative,

so after consultation, I will suggest the most appropriate method.
