My daughter “Eri” had Class Ⅲ with anterior open bite, but I was unable to accept the existing treatment method, so I studied with Biobloc therapy and cured Eri. However, I found that it was difficult to treat Class Ⅲ with this therapy alone. In order to treat them, I developed RAMPA, this appliance to induce the cranial base antero-superiorly. Based on the clinical results I had obtained, I found that this treatment was not only effective in modifying the form of the cranial, but also improve the anterior head position. It led to the extensive broadening of the range of treatments. Having been adapted to skeletal deformity and used in a variety of appliances, this method is named “Orthocephalics: RAMPA therapy. There is no doubt that forward inducement is carried out by Biobloc and RAMPA, but the latter is considered to belong to orthopedic treatment. “Orthocephalics” was originally named by Enlow and Harvold et al, and was published in 1977 on A. J. O. I opened a clinic specializing in RAMPA and Biobloc in Tokyo in 2012, and have been holding seminars in addition to treating many patients.


“Orthocephalics : RAMPA Therapy”


It is pointed out by a lot of researchers that the way of respiration is affecting the craniofacial skeletal structure. At the same time, it is true that the cephalic presentation is a major question. The relation between the space in the airway and the rest position of head seem to be inseparable bound up with each other, however, it might generate distortion of the skeletal structure. Such deformation causes a facial deficiency and abnormal swallowing, as well as malocclusion and oral respiration. RAMPA therapy is adopting the concept of rest-cephalic presentation to find a clue to solve these problems.
