Finite element analysis of the transfer of sound in the myringosclerotic ear.

This work presents a biomechanical study of myringosclerosis (MS), an abnormal condition of the ear that produces calcification of the lamina propria of the eardrum. The study researched the transfer of sound to the stapes depending on the localization, dimension and calcification degree of the MS plaques. Results were obtained using a validated finite element model of the ear.

Finite element stress analysis and fatigue behavior of cast circumferential clasps.

Statement Of Problem: Deformation and fracture of cast circumferential clasps may be a result of stresses induced during mastication. Most biomechanical clasp studies have been performed only under static conditions. There is little information regarding behavior of clasps over time.
