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.

possibility of gaining dental license of other countries

 Can a Japanese dentist get a license of dentist in other countries? Each country has its own rule. To get a license in US, you have to study in a dental college for designated years and pass the exam of each state, like a native student. It sounds the long and winding road. But, some countries are giving an easier chance for foreign dentists. In Australia, the number of dentists is said to be relatively small. Actually, Australia has welcome mode to immigrants of dentist from other countries.

  I went to Gotanda Tokyo to attend an explanation meeting from the tour company”M.I Studies Abroad”. The shortest way to get a license of Australia is sending the application form, (if it’s accepted), sending IELTS score certificate (reading, listening, writing, speaking score must be over 7(1-9) respectively), written exam of dentistry, and final clinical exam. The clinical test takes 6 days. If all procedures are successful, you are enrolled in Dental Board of Australia and can perform there. Visa is necessary to perform. According to the company, no Japanese dentists has got the license through the process. Foreign dentists who could attain the final are always Korean, Indonesian, Chinese, and other south east countries’ dentists. The whole fee of the tests is around 1,000,000 yen except for staying fee.

 The staff said “You can maintain three wives if you succeed as a dentist in Australia”. hahaha. Sounds intriguing? Me? My bottleneck is age. They say it may be difficult to get Visa for people over 50. The only thing I can do is just study English and get high score in IELTS. Will dream end in dream?

Making a complete denture…It’s fun

Most Japanese dentists don’t carry out teeth arranging in making a complete denture. They usually order that to dental technicians. My mentor always says arranging teeth sould be a dentist work, not technician’s. It may look painstaking for some dentists. But, for me, it’s really fun. Making a useful device(full denture) from nothing(no real teeth in the mouth) is exciting, imagining the patient’s smile.
In the process, I don’t totally rely on my instincts (of course, experience can not be ignored). “Shilla system” which is a kind of occlusion analyser is really helpful in setting the 3D positions of teeth. This will guide you to a nice goal due to the standardization.

Mikimoto Pearl Museum

The Mikimoto Pearl Island is an excellent museum about pearls, pearl
cultivation and Mikimoto Kokichi, the first person who succeeded in cultivating
pearls. The island is located in the Bay of Toba, accessible via a bridge.

Mikimoto Kokichi was born in Toba in 1858 and became the first person to
successfully cultivate pearls in the year 1893. He opened the first Mikimoto
Pearl Store in 1899. The Mikimoto Kokichi Memorial Hall introduces his life
Also located on the island, the Pearl Museum provides detailed explanations
about pearls and the cultivation of pearls in Japanese and English. In the
adjacent Pearl Plaza you can view and purchase a wide variety of pearl jewelry.
The Mikimoto Pearl Island also offers hourly performances by female pearl
divers, known as Ama (lit. “sea women”), who have traditionally been planting
and harvesting the oysters (and other seafood).

Combination of skills, it’s fun!

Collapsed bite cases, which require wide varieties of skill to fix, are challenging for dentists. However, I am excited whenever I face them. In such cases, thinking process for treatments is really fun for me. The case below is the combination of techniques such as diagnosis of occlusion, implant, orthodontic treatment, gum surgery, and crown restoration. The treatment took 2 years. I want to thank the patient for his understanding and cooperation. Without them, I couldn’t have reached the goal. I will describe the prosess, step by step later.

Pursuit of happiness for the patrients and truth for occlusion

Occlusion is the most basic factor in dentistry. However, there are several different theories. They look different, but the goal is the same? How can a dentist set an ideal occlusion? What is the landmark in oral anatomy? How can a dentist have an appropriate 3D image of occlusion? Are there really science factors in dentistry? What is the truth? Sounds very confusing? Abe’s Shilla system must be a solution. Its philosophy is crystal clear without ambiguous explanations. It’s really persuasive and useful in actual planning in treatment. I believe I have helped some patients who had eating problems, using the theory. They said they felt A-one after the treatment. I want to continue pursuit of happiness for my patients.

Today’s seminar

I went to Kanda Tokyo to attend a seminar. Dr. Abe is 77 this year, but he is nicely energetic in his lecture and demonstration. After he graduated from Nihon University 50 years ago, he went to USC in US and had great American mentors. He learned complete denture’s theory and skills from them. After he returned home, he opened his own dental office in Sendai Japan. Then, he began complete denture seminars not only in Japan but also in Korea and Taiwan. He knows anatomy well and has great knowledge of dental materials. He arranged former skills adding his own ideas and has established new remarkable theory and techniques called Shilla system. He sometimes changed some parts of procedures for making full dentures, because dental materials have developed gradually. I have learned many theories, but I think Dr.Abe’s thinking is the most persuasive and useful.

After the seminar, I could see a festival by Kanda shrine. Unfortunately rainy though.

Blade teeth for full denture




When patients use their complete dentures, are natural shaped artificial teeth enough effective to chew? 80% of all denture wearers want more than what is being offered to them. Sadly, conventional acrylic teeth even if hardened have a tendency to become less efficient in a short amount of time. The patients must chew from side to side to get results.
The idea of blade teeth is a solution to pursue more effective and enjoyable eating life. Food that posed a challenge for denture wearers in the past (meat, apples,lettuce,carrot) are easily cut up by the blade teeth denture.

Advantages of metal edged teeth compared with conventional ones are
1. easy to get comfortable jaw relationship
2. better chewing since cutting force is better
3. creates more stability in upper and lower dentures
4.less adjustments are required because of less sore spot

This weekend, I can learn the technique of complete denture through my mentor’s demonstration, while I work as an instructor in the seminar.

Alex Ferguson’s retire

My English teacher, from Manchester UK, sent me his article about Alex Ferguson’s retire.

In off-season, there is much news about personnel transfers in football teams. Especially this year, many J-League teams changed their managers. The big upside of changing managers is activation for the teams. Competition for becoming regular players starts from scratch. Players, who had few chances to play in games, will be motivated. Present regular players will be alert. There will be a race.

The upside of continuously hiring the same manager is accumulation of tactics. That makes possible in step by step approach. Changing players by trades instead of changing managers can activate the team.

He has succeeded in alternation of generations and activation of Manchester United by being not dependent on big names and adding ambitious young talented players to the team.

Though my clinic is an small organization unlike Manchester United, there must be some points which should be mimicked in his leadership for organising.
