Clinical use of glassfiber-reinforced composites post and core

PURPOSE:To evaluate the usefulness of glassfiber-reinforced composites post and core in restoration of serious dentine defects.METHODS:59 cases,87 teeth with serious dentine defects were selected.Glassfiber was used as the reinforcement frame and glassfiber-reinforced composites post and core were fabricated.Then the defected teeth were restored with porcelain-fused-metal crown.All patients were asked to re-visit 3 months,6 months and 12 months after treatments.RESULTS:2 cases(3 teeth)were out of visit 12 months after treatments.The restorations of other 57 cases(84 teeth)were firm and the occlusion was rebuilt satisfactorily during 12 months' clinical observations.Only one crown restoration was found to be loose.But the post and core was found to be still firm after the crown was taken off.Satisfactory results were achieved after being restored again.No dentine fracture was found in all restored teeth.The clinical results were satisfactory.CONCLUSION:Glassfiber-reinforced composite can be considered as a good material to fabricate post and core due to its high-strength,aesthetics and convenient operation.
