| Abstract Scope |
Quantitative percussion diagnostics (QPD) is a mechanics-based methodology that tests the structural integrity of teeth noninvasively. The purpose of the present study was to evaluate QPD clinical data for a lateral incisor tooth using computational modeling. Three‑dimensional models of the maxillary lateral incisor were developed incorporating the tooth structure materials. In order to study the effects of the crack lengths and orientations when exposed to percussion force, FEA models of the tooth and the QPD handpiece device in a variety of model scenarios compatible with observed clinical data were developed. Specifically, the force signal from the sensor in the QPD handpiece was simulated as a function of time. The models showed changes in QPD response are the result of oscillations between crack faces. The models confirmed that these oscillations can occur and QPD can detect cracks even when the plane of the crack is parallel to the direction of percussion. |
