Abstract
In conventional medicine and life science the most important concept for human life is not only the energy metabolism of mitochondria, but also the environmental energy system and the biomechanical energy system of animals themselves. However, this concept of energy has been completely over-looked. Introducing not only energy metabolism of mitochondria but also environmental energy as well as the animals own biomechanical energy of behavior into life science and medicine the author has established a new concept of Stomato-facial and Neuro-cranial medicine. From the standpoint of the new concept of medicine introducing energy, the author has developed new gompholic artificial dental roots, which have root supportive fibrous articulation instead of dental implants, which function via the ankylotic system. They are now in vogue. The concept of conventional dental implants completely lack of the odontology of the mammalian tooth. Therefore, all conventional ankylotic dental implants have no tooth supportive joint system, i. e., the remodeling system of the jawbone. The authors investigated the material, shape, and functional effect of the artificial root from the viewpoint of biomechanics and have developed effective gompholic-type artificial roots which have fibrous bone( cementoblasts) with fibrous ligaments and the alveolar bone proper. With these roots basic studies using animals, namely dogs and Japanese monkeys, were carried out. After that biomechanical studies were also carried out.Titanium artificial roots with a characteristic undulated configuration were developed, which were implanted into jawbone of dogs and monkeys. Immediately after implantation in the molar region artificial roots were fixed with a sequential crown; afterthat the chewing movement of mastication began. These mastication movements are converted into hydrodynamic energy concomitant with streaming potential around the roots, by which cementoblasts, the alveolar bone proper and fibrous tissue with capillaries are induced. Histopathological studies via light microscopy as well as studies of SEM, and micro analyzer were carried out. Following that, biomechanical numerical studies by means of FEA comparing gompholic and ankylotic as well as shape effects of artificial root configurations were carried out.
