Objective To study the clinical effect of the improve metal cast post core used on the badly damaged maxillary ifrst molar tooth. Methods Prepare the clinical patients 44 members,men 17,women 27,from 23 to 47 years old.elect the residual roots or crowns of the maxillary ifrst molar tooth,the root canal treatment is correct and perfect. The lingual root post is made of the medal cast post core,and leave two small caves in the core;then insert the ifber composite resin posts in the buccal root canals and cling them. Then combine to use as the improve metal post on the post core crown. the control group clinical patients are 42 members,men 20,women 22 .Results The improve metal post can improve the strength of the cling post core,clinical effect is perfect,operation is easy and convenient. Conclusion The improve metal post to treat the badly damaged maxillary ifrst molar tooth not only spare the materials but also improve the post’s resistance form and retention form.
