Fracture resistance of teeth restored with different post systems: in vitro study
2008, Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and EndodontologyCitation Excerpt :A cellulose mold was used to build up the composite core standardizing the size of the core for all specimens. Specimens were tilted at a 130° angle from the horizontal, and continuous compressive loading was applied, as it was shown to be the most clinically comparable angle of loading in anterior teeth.38,42,46,49 However, other studies used different angulations from horizontal, as 60° angle,18 and 45° angle.5
Influence of remaining coronal tooth structure location on the fracture resistance of restored endodontically treated anterior teeth
2006, Journal of Prosthetic DentistryCitation Excerpt :The cast crowns were cemented (Nexus 2; Kerr Dental) under a static 20-N load (Fig. 2).19 A universal testing machine, with a load cell having a maximum capacity of 1000 N (MTS 858; MTS Systems Corp, Eden Prairie, Minn), was used to apply a compressive load to tooth specimens with a crosshead speed of 0.5 cm/min at an angle of 135 degrees to the long axis of teeth10,20 until failure occurred (Fig. 3). This labially inclined compressive force was applied to the notch on the palatal surface of the crowns.

2005, Journal of Prosthetic DentistryEffect of core stiffness on the in vitro fracture of crowned, endodontically treated teeth
2002, Journal of Prosthetic DentistryCitation Excerpt :No significant difference in fracture resistance was found, suggesting that the crown distributed stress from the core onto the tooth root, thereby rendering core stiffness nonsignificant. This finding is in accordance with another study in which the build-up material was the only variable under the loaded crown.20 Control specimens contained only a stainless steel post and dentin core.
