Abstract:
1. A system for detecting irregular bone defects during dental implant osseointegration process, comprising: a dental implant, comprising a substrate holder and an implant, wherein the implant of the dental implant is configured to be embedded into an alveolus bone, and wherein the dental implant is made of metal; a detecting abutment, disposed on the substrate holder of the dental implant, and the detecting abutment comprising a main body and a plurality of piezoelectric transducers, the plurality of piezoelectric transducers being disposed around a periphery of the main body and placed at regular intervals; an ultrasonic driver, for driving the plurality of piezoelectric transducers to generate ultrasonic wave; and a signal receiving and analyzing device, for analyzing a time domain voltage signal transmitted from the plurality of piezoelectric transducers; wherein the ultrasonic driver is configured to drive the plurality of piezoelectric transducers to generate the ultrasonic wave and transmitting the ultrasonic wave to an interface between the dental implant and the alveolus bone, wherein the plurality of piezoelectric transducers are configured to receive a reflective wave reflected by each portion of the interface, and the reflective wave is further transformed into the time domain voltage signal, wherein the signal receiving and analyzing device is configured to receive the time domain voltage signal and to determine depth, severity and locations of the irregular bone defects of each portion of the interface between the dental implant and the alveolus bone, and wherein a material of the main body of the detecting abutment is the same as which of the dental implant.
