Conclusions The most frequently reported failures in the available studies were as follows : fiber post debonding , loss of retention of single crowns , and marginal gaps .
Less frequently , chippings and fractures were recorded in SCs .
Objective The present systematic review aim ed at assessing data from the literature on endodontic and prosthetic complications in endodontically treated teeth restored with fiber posts and single crowns ( SCs ) or fixed dental prostheses ( FDPs ) .
Effect of tooth type and ferrule on the survival of pulpless teeth restored with fiber posts: a 3-year clinical study.
PURPOSE To determine , in a 3-year clinical trial , whether tooth type and ferrule significantly affect the survival of pulpless teeth restored with fiber posts . METHODS A sample of 87 teeth in 87 patients ( 32 men and 55 women , age ranged from 23 to 78 ) were restored using Snowpost : 34 incisors , 12 canines , 25 premolars and 16 molars . The posts were cemented with RelyXUnicem and the core was made with a resin composite ( Dentocore Automix ) . Every tooth was covered with a metal-ceramic or all ceramic crown . Two experimental groups , according to the presence or absence of ferrule , were defined : A ) 45 teeth with ferrule ( > 2 mm height ) ; and B ) 42 teeth without ferrule ( < 2 mm height ) . Patients were reevaluated every 6 months . RESULTS 14 of the total restorations failed ( 16.1 % ) . The failure modes were caries ( n=4 ) , post fracture ( n=4 ) , root fracture ( n=2 ) , and marginal gap , post cement failure , crown cement failure , and periapical lesion ( n= 1 respectively ) . In Group A the failure observed was 6.67 % and in Group B it was 26.20 % . The log-rank test showed statistically significant differences between both groups . According to the type of tooth , the incisors were the teeth with the highest failure rate ( 73.52 % ) , but Chi-square test showed no statistically significant differences among the four tooth types , perhaps because of the low number of the sample
