PURPOSETo investigate the possibility of bio-mecanical acceleration of orthodontic tooth movement with physical energy of ultrasonic and laser beam, we made several research on the following subjects.1) basic study on the penetrative sensitibity of Ga-Al-As semiconductor laser (MORITA INDUSTRY, 790nm, 60mW, continuous wave) in living tissue2) evaluation of the magnitude of living tooth vibration being in contact with ultrasonic chip (28kHz, amplitude : 10mum)3) histological survey on peridontal tissue of Wister rat's molar being orthodontically moved by Waldo's method combined with the physical acceleration of ultrasonic vibration and/or laser beamMETHODS AND RESULTS1) The amount and the distribution of the semiconductor laser beam on the penetrative sede were quantified. Tissues used in this study consists of mandibular cortical bone derived from human and ox, masseter muscle, fat tissue of ox and human venous blood which were all collected in fresh status on the same day of measureme … More nt.Percent transmittance of cortical bone in 1.0mm thickness reached 50% and the distribution of the beam power on the penetrativee side showed remarkable scattering and some absorption and scattering were observed. Blood indecated lower level of the transmittence ; the beam power seemed to be attenuated by absorption rather than scattering through blood.2) Several upper molars of Wister rats among which orthodontic elastics had been inserted between M1 and M2 one week before measurement were used in this study. The upper jaw was fixed tightly on measuring equipment under wet condition immediately after the sacrifice.Compared with the control sides (without elastics) the experimental sides showed remarkably higher frequency (3-11kHz) and larger amplitude (12-24mum).3) 120-second laser beam were irradiated four times and 30-second ultrasonic vibration were given three times during 2-week experimental period.According to the histological observation, laser irradiation accelerated the bone remodeling and tissue repaire of periodotium after tooth movement. On the othe hand, ultrasonic vibration enhanced bone resorption and delayd bone formation. Laser irradiation with ultrasonic seemed to decrease this phenomena. Less
