What are certified orthodontists and mentors?

We are specialists certified by the Japanese Orthodontic Society. The growth of upper and lower jaws is not always favorable. It is important that the upper jaw is in proportion to the lower jaw. The asymmetric growth of jaws can be modified during puberty. The pubertal period is important for controlling the balanced growth of the upper and lower jaws. If abnormal growth and development of jaw bones are left untreated, patients may regret their decision in not having had treatment earlier on in life.

Orthodontists are not only specialists in orthodontics, but also in facial growth. As a result of their extensive knowledge and experience, they are able to predict and control the growth of both the face and jaws.


For proper occlusal contact between the upper and lower dental arches, the upper and lower jaws and each individual tooth must be correctly aligned. Orthodontists refer to teeth which do not occlude properly as abnormal occlusion or malocclusion. Orthodontists require knowledge of the growth, differentiation, development, dissection and physiological functions of teeth, jaws, and face in order to correct malocclusion. In addition, orthodontists must be adept in the use of technology to provide precise, 3-dimensional movement, and have the skill to correctly induce or control tooth emergence, and also the growth of jaws and facial growth. Today, in countries around the world, including Japan, the treatment of abnormal occlusions are performed by dental specialists with orthodontic skills.The Japanese Orthodontic Society authorizes certification to specialists in Orthodontics in order for them to become certified orthodontists or mentors. Our department has 4 mentors and 7 certified orthodontists.
