Abstract:

BACKGROUND: The elastic modulus of glass fiber posts is approaching to teeth structure. So it can share the masticatory force with teeth, which can ease the stress concentration of dentinum and prevent from tooth fracture.
OBJECTIVE: To analyze the clinical effects of glass fiber posts on restoration of residual root and residual crown of front teeth.
METHODS: A total of 171 affected teeth from 96 out-patients in Guilin Stomatological Hospital were treated with root canal therapy, and then divided into three groups: restored by glass fiber core and crowns, prefabricated alloy post and crowns, cast alloy post and crowns, respectively. Cobalt-chromium alloy ceramic crown repair was followed. All patients were visited for 6-24 months as follow-up.
RESULTS AND CONCLUSION: The falling rate between glass fiber post group and cobalt-chromium alloy group had no statistical significance (P > 0.05), but root fracture rate had statistical significance (P < 0.05). The falling rate of glass fiber post group and prefabricated alloy post group had statistical significance (P < 0.05), but root fracture rate had no difference (P > 0.05). The restorations of glass fiber posts are superior to metal core and crowns, with good clinical application prospect.
