Resonance Frequency Confirmation for Osseointegration of Dental Implantation In Vitro Models With Varied Cortical Thickness¹

The titanium implants have been used as prostheses to replace missing teeth of patients for over two decades. The osseointegration was used to define a direct structural and functional interface between living bone and surface of implant [1]. A dental implant may appear defects as a result of infection and early loading during the healing phase. Therefore, the osseointegration assessment after implantation is an essential issue for clinical dentists and researchers. The healing of dental implantation progresses in two stages, i.e., the primary stability and the secondary stability. In dental osseointegration, one bone remodeling cycle takes about 3 to 6 months for human. Thus, the primary stability (1 or 2 months after surgery) usually indicates a sensitive and risky duration for future probable failures [2]. The most popular noninvasive method currently available to access quality of osseointegration is radiography, but it is difficult to support dentist...
