“Oral Design Symposium 2015”

in Madrid, Spain

Participating in "Oral Design International Symposium in Madrid"

—Four days in Madrid, Spain, where you were exposed to cutting-edge aesthetic technicians—



The title event was held for the first time in two years in Madrid, Spain, for four days from September 16th (Wednesday) to 19th (Saturday), 2015.

"oral design" is an organization composed of dentists and dental engineers presided over by Mr. Willi Geller, and a symposium is held at a pace of about once every two years for the purpose of fellowship between members and the transfer of knowledge and skills. In the first two days, a hands-on course was given by 6 lecturers, and in the second half, 17 lectures were given, and 400 people from all over the world participated.

The author participated in this event for the first time this time, and I was able to gain valuable experience in thinking about various thoughts about dental technicians. I hope that the content reported in this article will be of some help to readers in the future. 


Feel the enthusiasm of the participants at the venue of the country of passion

Having prepared for this day for several years, I arrived in Spain the day before the seminar with great tension and expectations, just like a child the day before the excursion. Unlike Korea, the sculptures on many buildings caught my eye and felt the weight of history . I usually rely on smartphones, but I was forced to inconvenience because I couldn't connect to the communication due to poor overseas settings. However, by shutting out information from the outside world in an era of information overload, I was there to be free from dependence on the Internet and to concentrate on the course.And it made me feel "what is the real convenience?"

It was one hour before the opening that I arrived at the lecture hall smoothly after finishing the city tour on the morning of the day. While the venue was busy with preparations, I registered at the reception and moved to the hands-on course venue. Seeing a room like an opera house with very large glass windows overlooking the beautiful city and the deep blue sky, I was fascinated by the feeling, "Is this really the venue for the hands-on course !?" I unknowingly kept pressing the shutter of the camera. There was enough atmosphere here to imply that if we could work while looking at this landscape, we would be able to make a crown that was better than usual.

Yet another thing that fascinated me was the environment prepared for the hands-on course participants. Towel engraved with the name of each participant are arranged in front of each seat along with the other tool or the like, have been all the way caught welcomed the hearts of the participants who came for this moment. The author is looking forward to collecting such heartfelt souvenirs. Even the champagne cork stopper opened during training under Mr. Yasuhiro Odanaka (Setagaya-ku, Tokyo / oral design Saiun) is a good memory of the author

Such a one by one of the memories of the goods is, the author to remind the original intention, and me of him pull out the motivation.


To the right of the author is a dental technician from Sweden, to the left is a young man from Russia who has received financial support from the company, and another dental technician from Italy who is currently working in Ireland. Dental technician who attended to learn more knowledge and skills while having famous experience in France, dental technician from local Madreed, etc. Participants from various backgrounds came all the way to meet in one place. Everyone was a little nervous, but I felt like he was doing it with a cheerful expression that he came to "learn something, grab something".


Hands-on course by 6 performers-Days 1-2

The author participated in a hands-on course with "Tooth as nature's work of art opacity control ZI-F" led by Mr. Luke Hasegawa. Oral design member Eduardo Setien Laboa acted as an interpreter for local Spanish dental technicians, and the gentle and calm voice added to the atmosphere of the lecture hall.


On the first day, a presentation was presented to explain various experimental results and one's own thoughts in an organized layout, and from the second day, a demonstration and practical training of a typical porcelain construction were held.

Mr. Hasegawa explained the features and design concepts of each company's products in an easy-to-understand manner based on the values recorded by conducting Opacity experiments on all porcelain materials such as dentin and enamel. It is said that the probability of failure can be reduced by deepening the understanding of the minimum required types of porcelain rather than using it. The more I listened to Hands-on, the more I realized that his notion of Opacity was wonderful.


For the author working in the in-hospital lab, Opacity was one of the physical characteristics that was as strong and familiar as brightness and morphology. Now that many coping materials such as metals, zirconia, and lithium glass ceramics disilicate can be selected, it is very important to understand and control the opacity derived from the materials.

From the content of Mr. Hasegawa's lecture, I realized that the idea I had gained (as a sense) in my clinical technique was not wrong in theory, and it was a very valuable lecture for the author.

On the other hand, I was surprised that some people have already recorded the considerations that I had only imagined as data and assembled it as a theory. It was a moment when I was shown the world-class height.

I met Mr. Hasegawa for the first time, but maybe because I knew him on Facebook in advance, I was able to talk so easily that I felt like I had known him for a long time. Of course, his friendly personality is one of the reasons. However, I once again felt that it was an advantage of SNS (Social Networking Service) to be able to make friends with people who lived in remote areas for the first time.
