Challenging case

 Recently, I had a patient who had trouble with dental implants which his former dentist had embedded. At first, I rejected to treat him. Because, the implants were different from ones which our clinic dealt with. I use implants produced by Straumman co. which has been used worldwide. I did not know the product maker of the patients' implants through the appearance and X ray images of them. It is said that there are over 50 implant makers in the world. Some new companies aim niche in the market, struggling to keep up with the technology of the companies already having big share. Sometimes, some companies' implants have kinks though they say their product are fool proof. I wanted to pull out the patient's implants with counter clockwise strength, because they were poorly positioned. Of course, considering patient's agony, I can't carry out it. He asked me to treat many times, and finally, I gave in. Now, I am enjoying the process of reconstruction of his occlusion.

Pontsuku, Kokura's sweets




Kokura is a smaller than Hakata (the capital city of Fukuoka) but growing town in Fukuoka prefecture Kyushu Japan. Since last September, I have attended a dental seminar held in Kokura, every second weekend in each month. Last week, before going there from Tokyo, a dental hygienist turned to me, “Doctor? Please buy souvenir for our staff”. She is called as a sweets commentator in my office. She gave me a list of sweets made in Kokura. It seems that she researched all day long on the Internet. Considering expiring date of the sweets, I chose Pontsuku (photo) which an old established store has made. It is a sponge cake including custard cream. There are other versions of cream, such as powdered green tea, chocolate, and strawberry. It was amazing, fluffy, fabulous and yummy. All our staff turned cartwheels. When you have a chance to visit Kokura, try Pontsuku, the awesome sweets!

10 years after sinus floor augmentation


 I sometimes encounter patients who don't have enough bone in upper molar teeth missing area for placing dental implants. I learned skills of sinus floor augmentation, surgery of growing new bone in sinus for upcoming dental implants surgery, at University of Michigan in 2002. The reason for going abroad was that I could practice the skills using cadavers in US, which has been prohibited in Japan. Since then, I have overcome the difficulties in placing implants in upper molar. This is one of such cases, CT scan images after 10 years showing stable condition. The more I learn, the more I can contribute.

The boys in the boat


When I was a university student of faculty of dentistry, I belonged to the rowing club. When I was 4th grade, our crew, coxed four, won a race in Japan and selected as a representative of Japan for university students Olympic, held in Italy in 1982. My position was number 3, role of engine in coxed four. We got 4th place in the final heat of 2000m, failed to get medals. After oarsman's era, I coached younger generation for 10 years. I learned not only skills of rowing and coaching, but also leadership. I grew good relationship with the team mates, all are dentists or doctors now, and still have meeting with them, enjoying talking and drinking occasionally. "The boys in the boat", describing Washington university crew winning gold in Berlin Olympic, is the book of rowing I encountered since "True Blue" dealing with the story of Oxford university crew's turmoil and winning the boat race in the end. It was a really page turner. I was moved to know how gung-ho the students were in those days namely Great depression, paying tuition by themselves through working in a quarry or a night pub after home work. The book gives energy to live.
 



Making sushi with warm heart

Dr. Kasugai, who is a professor of the dental implant section of Tokyo Medical and Dental University, invited my clinic's doctors to "Kanpachi",one of famous sushi restaurants in Tokyo (Dinner time;15,000yen~). Many Japanese like to eat sea urchin, but I don't.  Nevertheless, I could eat one with pleasure here for the first time in my life. Other kinds of sushi and sake are all the best. The master, Mr. Yamada, is 81 and has kept this restaurant for 50 years. He can speak English and has some non-Japanese guests, so if you have a chance to come to Tokyo, it's worth enjoying true sushi here in Kanpachi. The photo is his autobiography titled "Making sushi with warm heart". The restaurant is 5 minutes walk from Okacimachi station. Tel:03-3832-7357

The heart of a leader

http://www.amazon.com/The-Heart-Leader-Insights-Influence/dp/0781445434/ref=sr_1_1?ie=UTF8&qid=1369315871&sr=8-1&keywords=ken+blanchard+the+heart+of+a+leader

A friend of mine sent me a book "The Heart of a Leader".

You don't have to start from scratch, but read any page you like. The most impressive page for me is the page 62 "Never give in! Never give in! Never give in! Never!"-Winston Churchill. I will re-read this book in a daily commuting train until each word soaks deep into my mind.

development of dental materials

 Things have changed dramatically in dentistry like every field of the world. Today, I treated a patient from UK who lost his front tooth crown. In order to fix the new all ceramic crown, I set a fiber core into the root canal with special adhesive. Then, I took a mold for the new crown. I checked the tooth color using lots of color samples to get good match against neighbouring all ceramic crowns.

 20years ago, I always used metal cores. But, for aesthetic purpose and avoiding root fracture, fiber cores had been invented. Since then, I sometimes has applied them. There are several adhesive materials and I have to choose the best. Lots of information makes me confused, but fortunately, my junior doctor knows well through his dental college hospitals' experience.

 As for new dental materials, each dentist has his own thinking. I must not depend on my past knowledge and have to get appropriate information by word of mouth. Because few dental books show what up-to-date material is and what the best is.
