In this study, three groups of post and core systems  (cast post and core, glass fiber and prefabricated  metal posts) are tested for resistance to fracture  under a continuous load and cyclic loading under  similar oral conditions. Zinc phosphate and Panavia 21 were used as cements of  choice because of their long history of reliability  and dependability. Marginal gap measurements were acquired using a high  powered microscope before and after testing in the  cyclic loading groups. For the load to failure groups, a constant but slow  speed load was applied to the teeth till failure. The two hypotheses for this study were: the glass  fiber group would have less marginal gap opening on  the lingual after cyclic loading than the other  groups. The second hypothesis was the cast post and  core would have a higher load to failure than the  other groups in this study.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843363518\"\u003e\u003ch3\u003eIn this study, cast post and core, glass fiber and prefabricated metal posts are compared under various loading conditions\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843363518","offer_id":39470078623837,"sku":"9783843363518","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/56ffb461-be79-46d7-910b-ccd8c632b23b.jpg?v=1769495659","url":"https:\/\/shop.autorenwelt.de\/products\/testing-various-dowel-systems-under-load-to-failure-and-cyclic-loading-von-amir-saad","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
