Two-dimensional photoelastic stress analysis of traumatized incisor.

In this study, stress of traumatized incisor and the effect of stress on tooth and alveolar bone was studied with two-dimensional photoelasticity. Two homogeneous two-dimensional maxillary central incisor models were prepared. Loads were applied to the labial side of incisal edge and middle third of the crown at angles of 45 degrees and 90 degrees. It was observed that stress was increased on t...

Photoelastic stress analysis of silastic poppets in prosthetic heart valves.

Some prosthetic heart valves with Silastic ball poppets undergo degeneration and variance. The problem is avoided with metal poppets; however, their impact can damage the cloth coverings on the struts, resulting in distorted blood flow paths. Consequently, renewed interest in mOd-cured Silastic poppets and inserts is developing. With photostress equipment, we analyzed two spherical poppet model...

Photoelastic analysis of stress generated by Connecticut Intrusion Arch (CIA)

OBJECTIVE The present in vitro study evaluated, by means of the photoelastic technique, the effects generated by the Connecticut Intrusion Arch (CIA), with a 90o bend on the distal surface of molar tubes and using the 4 x 2 appliance on the anterior and posterior regions of the upper dental arch. METHODS Five models were manufactured, in which two different clinical situations were correlated...
