[Three-dimensional finite element stress distribution and displacement analysis of alveolar ridge retained by conical telescope].

OBJECTIVE

To study the stress distribution and displacement of edentulous alveolar ridge of removable partial denture which is retained by using conical telescope.

METHODS

An ideal three dimensional finite element model was constructed by using SCT image reconstruction technique, self-programming and ANSYS software. The static load was applied. The stress and displacement characteristics of these different types of materials which form the metal part of the conical telescope were compared and analyzed.

RESULTS

Generally, the four materials produced almost the same stress and displacement at the site of the edentulous alveolar ridge.

CONCLUSION

From the viewpoint of dynamics, the application of different materials in making the metal part of conical telescope is feasible.
