Abstract
The present study deals with in-situ microgap measurements in the internal taper connections of dental implants. Using X-ray phase contrast microtomography, the connecting interface between implant and abutment is probed non-destructively in three dimensions. Interference fringes across the conical interface occur due to the presence of microgaps, their intensity being a measure of the gap's width. Thus, for each point on the interface, interferences are extracted from the volumetric image in terms of normal projection maps which are, at selected points, compared to forward simulations to quantify the local gap width. Four designs of dental implants are tested in the “as-received” state as well as after application of cyclic extra-axial load. Results show different degrees of microgap opening by cyclic deformation according to the implants' design as well as a great amount of detail on the actual interface, i. e. fretting scars, grooves and wear debris.
