Halfway Through 2026, and the Resin Fanatics Went to Japan Again

A Diary by a Dentist Running a Dental Clinic in Gangnam

If it’s a diary by a practice owner, then it’s a practice-opening diary (that’s what I insist on calling it).

At the end of June,

I gave a lecture on anterior resin restorations

at the 2026 academic conference of the Korea University School of Dentistry Alumni Association, which mainly consists of specialists trained at Korea University University Hospital.

While running a dental clinic in Gangnam specializing in anterior resin treatments,

I have built up a great deal of clinical know-how,

and I think I have especially helped many patients learn about this excellent treatment.

Of course, there are people who are better than I am,

but when it comes to performing resin veneer treatments frequently,

I think I am one of the few who comes to mind.

I was truly grateful to be invited to an event like this..

I was moved that everyone listened with such complete focus..

And I am always grateful to my wife for taking care of our child on her own all this time..

So the next day, Sunday, I took our child

to Ground Planet at Seoul Grand Park in Gwacheon.

The little one, who normally never lies down,

ran around and played for eight hours,

then must have gotten tired and ended up sprawled out and rolling around..

Everyone, make sure you have a baby boy.

Actually, the weekend before that, I had

gone to Japan again.

The certificate on the left is from my trip to Japan last October

to attend Professor Yukihiro Kosaka’s lecture on anterior resin,

while the certificate on the right is from this trip.

Dr. Rodri Thomas, a British dentist, was giving a special lecture on anterior resin in Japan,

so I went to Japan again for three days and two nights,

together with several clinic directors who are crazy about resin—also known as “resin fanatics.”

Just like last time,

it was an exhausting trip where we went to Japan,

listened only to lectures, did absolutely no sightseeing, and came straight back.

I have been to Japan twice, and both times I only got to see the hotel and the conference room...ㅠㅠ

Still, since I went there to study rather than to have fun,

I did feel a little less guilty toward my wife,

but I was still sorry.. grateful.. and I love you..

Anyway, speaking about the seminar,

I first encountered resin veneers (Direct Composite Veneers)

at a seminar at King’s College London a long time ago,

and since then I have continued studying them and have run my clinic specializing in this treatment.

Rodri is British, but he used a technique I had never seen before.

That was truly fresh and interesting.

Still, perhaps because I have built up quite a bit of experience with anterior resin,

when Dr. Rodri saw the anterior resin treatment I had practiced,

he told me it was the best he had seen in ten years,

really boosting my ego(?)

and then, in front of the Japanese dental clinic directors,

he provoked them by saying, “The Korean is the best right now. The Japanese need to step it up.” ㅋㅋ

On the second day as well,

I was happy to hear him praise me, saying it was “so natural” (just like a natural tooth),

that it was the best, and that I was very skilled.

This was the seminar,

and Dr. Min-uk Choi of Oedae Able Dental Clinic asked me to go with him,

saying, “How can you hear Art of Resin in Japan?

This is an incredible opportunity.

You absolutely have to go.”

So I went with him, and I really do think it was worth it.

Since opening my clinic, I think I have treated more than 500 patients—

and nearly 1,000 teeth—in anterior resin cases alone.

By making the most of these cutting-edge concepts and techniques,

I am always working to provide patients in Korea with world-class treatment.

That is my mission and what gives me a sense of fulfillment.

Even if natural teeth cannot be perfectly replicated,

I believe that striving toward that goal

is the aesthetic quality I pursue.

Anyway, I am doing well.

I cannot be 100% satisfied with results at this level,

but it is fun to meet around ten patients a day,

send home those who do not need treatment,

treat each patient with care when treatment is needed,

and achieve results in the areas I am good at.

1. Anterior resin treatments

2. Lecturing

3. Writing and publishing

4. Personal development (studying)

Living while doing everything you want to do

is a happy thing.

Now, do I just need to make money? When will I become rich?

Today, I once again saved a tooth that had been diagnosed elsewhere as needing root canal treatment

with a biomimetic resin build-up treatment.

It was a challenging treatment.

I carefully removed the decay by scraping it out with hand instruments rather than a drill,

taking care not to expose the pulp as much as possible.

I also placed a layer of UHMWPE fiber.

I filled the inside with everX resin.

For the outermost surface, I shaped it with Grandio resin.

Today, I also saved(?) another patient’s tooth with a simple resin treatment

after they had been diagnosed elsewhere as needing root canal treatment.

They had been told that they needed root canal treatment and a crown as well.

For the patient above, I told them that root canal treatment was more likely even in my opinion,

but that I would do my best to save the tooth, and then proceeded with treatment.

But with this patient.. as soon as I saw the tooth, I found myself reacting,

“You were told you needed root canal treatment?”

I’m sorry.

Purchase confirmed: May 2026

Oh, and speaking of an entirely unrelated personal-purchase review,

this is an organizer I used for the first time when I went to Daegu to give a lecture in June.

I bought it as a set with the table mat, but it can also be purchased separately.

This is really nice.

It lets me organize all the tech odds and ends I need when I go to give a lecture in one place,

and it has dividers inside

so that everything can stay in its proper place.

I used it when I went to give the lecture for the Korea University alumni association as well,

and it is such a soothing arrangement, isn’t it?

TODA Building in Japan, where the resin lecture was held this time

Ah, anyway, I should take my family to Japan for a vacation sometime too.

People say that Japan’s economy is doing poorly and that the country has failed,

but I felt that it is still a developed country with solid foundations because

first of all, the materials and interior design of the buildings were truly incredible.

In Korea, a lot of money is spent on residential buildings,

while commercial buildings tend to focus on cutting costs.

But I got the impression that Japan builds its buildings in almost the opposite way.

I also had the impression that the streets were exceptionally clean.

One of the clinic directors told me that in Japan,

you cannot buy a car unless you have a private parking space.

That is why there are no traffic jams even in central Tokyo,

and, above all, there were no cars parked on the back streets.

He said that this is the factor that makes Japan’s scenery most different from Korea’s.

It was fascinating.

A video like this happened to appear today, so I watched it,

and this architect also said that parking-space regulations are the biggest difference.

Ah, anyway, half of this year has already passed.

I will work hard and keep moving forward in the second half as well.

I still write the blog myself, like I used to.

I will occasionally write diary entries like this, following the flow of my thoughts.

I would also like to share some real 고민s about how best to run a dental clinic.
