Intracanicular dental implants

Intracanicular dental implants used in the reconstruction of severely damaged teeth must provide maximum stability and adhesion to the root of the original tooth. Failures arise principally when external infiltrations reduce adherence of the peg to the tooth, or when poorly balanced forces concentrated at the extremity of the tooth cause root fracture.

 

Elettra's contribution
Microtomography with synchrotron light has long shown itself to be the best of the various techniques available for obtaining a three dimensional reconstruction of bony areas around implants. The ability to vary the X-ray energy at will makes it possible to choose a level of contrast for the high resolution image that is appropriate to the density and characteristics of the tissue under examination.
This analysis technique, which has enabled the improvement of simulation programmes that predict the behaviour of reconstructed teeth, can also be applied to the mechanical characterisation of tendons, ligaments and vertebral discs, and allow designs for artificial substitutes to be optimised.
