Detection Device for Dental Implant Osseointegration Using Inductors and Hall Sensors¹

Titanium-made dental implants have been proven as an effective treatment for both completely and partially edentulous patients in the past two decades [1]. The surgery may fail if prosthesis is treated erroneously in placement or loaded inappropriately. Bone loss and yielding defects usually reduce implant stability and eventually cause surgery to fail. The overall issues show the importance of assessment during the osseointegration; especially, the indication to single out the portion of structure instability helps dentists remedy such a situation [2]. Many developed techniques and devices have been proposed to assess interfacial osseointegration and quantify bone defects. Both static and dynamic measuring devices have been investigated, implemented, and even commercialized [3–5]. Compared with invasive methods like removal torque analysis, noninvasive ways are considered more practical in clinics; for instance, the techniques through radiographic observation [3], static inspection [4], and dynamic...
