Thirty human maxillary central incisors were distributed in three different groups to be restored with simulation of different restoration stages (1: only post, 2: post and core, 3: post\u2010core and crown), using Rebilda fibre posts. The specimens were inserted in resin blocks and loaded by means of a universal testing machine until failure under tension (stage 1) and 50\u00ba flexion (stages 2\u20133). Half the specimens in each group were restored using a simulated ligament between root dentine and resin block and the other half did not use this element. Failure in stage 1 always occurred at the post\u2010dentine interface, with a mean failure load of 191\u00b72\u2003N. Failure in stage 2 was located mainly in the core or coronal dentine (mean failure load of 505\u00b79\u2003N). Failure in stage 3 was observed in the coronal dentine (mean failure load 397\u00b74\u2003N). Failure loads registered were greater than expected masticatory loads. Fracture modes were mostly reparable, thus indicating that this post is clinically valid at the different stages of restoration studied. The inclusion of the simulated ligament in the experimental system did not show a statistically significant effect on the failure load or the failure mode.<\/jats:p>","DOI":"10.1111\/j.1365-2842.2011.02249.x","type":"journal-article","created":{"date-parts":[[2011,9,14]],"date-time":"2011-09-14T07:35:23Z","timestamp":1315985723000},"page":"188-197","source":"Crossref","is-referenced-by-count":6,"title":["Experimental strength of restorations with fibre posts at different stages, with and without using a simulated ligament"],"prefix":"10.1111","volume":"39","author":[{"given":"A.","family":"P\u00c9REZ\u2010GONZ\u00c1LEZ","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"GONZ\u00c1LEZ\u2010LLUCH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
