[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.


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