DISCOVERY OF STRESS DURING ANCHORING OF THREADED DEVICESWITH THE HELP OF PHOTOELASTICITY AND TENSOMETRY
Abstract:
To restore the teeth with endodontic treatment, most practitioners use small corono
prefabricated root. Restoration of coronary stump is made by means of restorative materials (plastics).
The literature abounds in this respect the materials and techniques. The present study’s objective was to
observe the in vitro mechanical stress behavior (axial and oblique pressure, and traction resistance) of
a number of teeth roots endodontically treated and restored using the post and core system.The
coronary post was restored using prefabricated DENTATUS devices, Silver Amalgam, Miracle-Mix,
Culmat, Dyract, 3M VITREMER and a compomer. A parallel direction that the study took was the
observation of the strength and behavior of these materials in wet conditions as opposed to their
resistance in a dry environment. This stage of the study took 8 days.
