Comparative study of two root-canal posts in residual crown restoration

Objective To compare the practical results of two post cores:the Anthogyr root-canal stainless steel post and the glass-fiber post,through methods of instant restoration of the residual crown and the restoration of the residual crown for permanent ceramic crown.Methods Totally 132 patients who have residual crown with 160 teeth were selected from the Department of Stomatology of Liuzhou People's Hospital from June to August 2009,and were randomly divided into two groups;in each group there were 80 teeth.And two methods were used to restore the residual crown respectively:the Anthogyr root-canal stainless steel post and the glass-fiber post.Both groups used light-cure tetric ceram to repair the residual crown and then restored the residual crown for permanent ceramic crown.The operation time and convenience,cost-performance,the corresponding period success rate and curative effect of the two groups were compared and studied.Results Through 2 years' follow-up,(100% vs 93.8%;χ2=0.069,P 0.05),there was no significant statistical difference between the two kinds of posts in corresponding period success rate.Conclusion The Anthogyr root-canal stainless steel post and the glass-fiber post have similar curative effects.But due to the former's unique design,hard retainer,easy operation and low price,it is worth spreading and applying.
