Noninvasive and nondestructive mobility assessment of dental implants is very important and useful for dental implantation diagnostic-aids. The development of implant movement (IM) checker based on microcontroller is presented in this paper. Data acquisition system and bender-type piezoelectric probe were used to improve measurement quality to the original(More)
This study aimed at developing a dental implant movement (IM) checker for assessing quantitative dental implant mobility. The design of the instrument was based on the tooth mobility (TM) tester, which was previously developed by our group. The IM checker consists of a newly developed measuring probe which has the size of a typical dental drill so that it(More)
The aim of this study was to ~develop a portable device (1M checker) for measuring dental implant mobility using a microcontroller. A constant amplitude and frequency vibration was applied to a dental implant model and the acceleration signal was detected using measuring probe. Then the 1M score was obtained using the criteria developed in this study. We(More)
Multilayer Langmuir-Blodgett (LB) films were fabricated with two blue transparent nonlinear optical polymers in which the orientation of the nonlinear optical chromophore in one polymer is reversed with respect to the other. The intensity of the frequency-doubled light generated in these multilayers increases quadratically, with the increasing number of(More)
