Abstract
Device for inspecting the stability of a dental implant () in a bone (), the implant having a free end () and an end () buried in the bone (). The device comprises an ultrasonic transducer () for emitting and collecting an ultrasonic wave reflected from a contact interface () between the implant () and the bone (), and providing a measurement signal representing the reflected ultrasonic wave. The device also comprises a processing unit for computing, based on the measurement signal, an indicator (IN) whose value makes it possible to evaluate the integration of the implant () into the bone (). The indicator (IN) corresponds to the average energy of the measurement signal over a time interval (t-t) starting at a first time (t) and ending at a second time (t). The first time (t) is between 20 and 80 μs after the start of the emission of the ultrasonic wave.
