While in junior high school, Dr. Hirohide Arimoto was given a four biscuspid extraction by his father, Takayuki Arimoto, who opened the first orthodontic clinic in the Kinki region of Japan in 1965.

In 1995, he visited Dr. Greenfield’s clinic in Florida, sceptical that the clinic had treated 98.5 percent of its patients using non-extraction treatment.

In 1996, Dr. Arimoto became an instructor of Dr. Greenfield’s non-extraction methods, founding the Japanese Academy of Non-Extraction Orthodontics (JANO). He established a diagnostic and treatment system called Molar Oriented Orthodontics (MOO) based on Dr. Greenfield’s CAD system, and published “Molar Oriented Orthodontics” from the publisher Ishiyaku-Shuppan in 2011.

He was invited as a presenter and received the Table Clinic Award as a member of JANO at the annual meeting of the American Association of Orthodontists at Philadelphia in 2002. He was also invited as a speaker at the first meeting of the Italian Non-Extraction Orthodontic Society in 2007, and he was the special lecturer at the eighth meeting of the Kyushu Orthodontic Society. In 2015, he was a speaker at the 41st Biennial National Meeting of the Edward H. Angle Society in Pasadena, California.

He has conducted MOO nonextraction seminars in Japan, US, Italy, Korea, India, Hong Kong and other foreign countries. He began providing invisalign treatments based on the MOO philosophy in 2014. Now he is the one of 12 Official Invisalign Clinical Speaker in Japan. The following year he began to use OrthoPulse®, the first oral device to use photobiomodulation for painless and accelerated tooth movement. As the world’s most experienced user of OrthoPulse®, he has also been a speaker of photobiomodulation in orthodontics and Light Accelerated Orthodontics at the the Japan Academy of Aligner Orthodontics (JAAO), the German Association for Aligner Orthodontics (DGAO), the French Aligner Society (SFOPA), and the Taiwan Association of Aligner Orthodontics. He is also one of 9 key opinion leader of Biolux Research in the world.

Dr. Oshima lived in the United States for three years as a child with her father, who is a doctor. There she met a friend, who while treating various diseases said that “the most painful thing is to lose your teeth,” a comment that would teach her the importance of healthy teeth. After returning to Japan, she received orthodontic treatment, and realizing the importance of oral health she decided to become a dentist. After graduating from Osaka Dental University, she worked at a general dental clinic, and studied at the university’s orthodontic department. In her nine years training at the university hospital, she has learned various treatment methods including tooth extraction, non-extraction methods and surgical procedures. Currently she is in charge of orthodontic treatment for a wide range of cases at dental clinics in Osaka, Kyoto, Hyogo and Nara.
