Evaluation of a one-piece milled zirconia post and core with different post-and-core systems: An in vitro study

Fracture resistance of compromised endodontically treated teeth restored with bonded post and cores: An in vitro study

“…Other studies using static loads favored cast and titanium prefabricated over fiber posts, 14 cast over fiber, 16 cast and fiber over titanium and stainless steel, 19 or prefabricated fiber and titanium over custom zirconia and cast posts. 20 The fracture resistance rates varied from 300 to 600 N or higher, 17, 18, 19 and 20 rates significantly higher than the ones observed in this study. This may be attributed to the various levels of remaining tooth structure used, whereas in our study there was no remaining tooth structure.…”

“…13 Many different post and core systems are currently available and differ depending on the post type, design, surface texture, fit, and material. Studies that compare various post types have yielded controversial results favoring cast, 14, 15 and 16 fiber reinforced, 17,18,19,20 and 21 titanium, 20 stainless steel posts, 22 or no specific type. 22 and 23 Some did not standardize the cement used, and so the systems could not be directly compared.…”

Fracture resistance of endodontically treated roots restored with zirconia post and different core materials

“…Similarly, in a previous study, the majority of failures for one piece zirconia post and cores were catastrophic, presenting root fracture with or without post fracture. 12 Additionally, a previous study by Bakke et al 13 determined the occlusal forces on anterior teeth to be 222 N. According to the values obtained in the present study, all of the systems exceeded this value. Since the failures occurred at much higher values than the average occlusal forces reported for anterior teeth, none of them could be considered at risk for failure as a result of normal occlusal forces.…”

“…3,4 Endodontik tedavili ön bölge diĢlerinde uygun restorasyon seçiminde dayanıklılığın yanı sıra estetik özellikler de önem taĢımaktadır. 5 Ön bölge diĢlerinin protetik tedavisinde genellikle ıĢık geçir-genliği özellikleri sayesinde estetik açıdan en iyi sonucu sağlayan tam seramik restorasyonlar tercih edilmektedir. 1 Ancak materyalin ıĢık geçirgenliği restorasyonun renginin, altındaki diĢ veya kor yapının renginden etkilenmesine neden olmaktadır.…”

“…1 Ancak materyalin ıĢık geçirgenliği restorasyonun renginin, altındaki diĢ veya kor yapının renginden etkilenmesine neden olmaktadır. 5 Bu sebeple endodontik tedavili diĢlerde tam seramik restorasyonlar ile beraber uzun yıllar yaygın olarak uygulanmıĢ metal postlar yerine estetik post ve korların kullanımı gündeme gelmiĢtir. Estetik post ve korlar iyi bir estetik sağlamanın yanı sıra korozyon ve toksisite riskini azaltmaları gibi avantajlara sahiptirler.…”
