A series of in-vitro bone defect models were designed as well as made, and their surrounding boundary conditions were also changed. The structural resonance frequency (RF) was first measured by the acoustic excitation-displacement response procedure, and then this result was applied to compare with the outcome of the commercial implant stability instrument measurement and the finite element analysis (FEA). Therefore, the correlation between the RF difference and the bone defect orientation/location can be determined, and the postoperative assessment can also be established. This technique promises to assist the dentist in diagnosing and decreases the failure of the dental surgery.
