How ? Why ?
NON - ODONTOGENIC CYST Misdiagnosis resulted in unnecessary endodontic treatment of four anterior teeth. 4/1972
The Result The Concern
Considerations for Anterior Teeth A metal post is not recommended in anterior teeth which do not require complete coverage restorations. This decision primarily focuses on: [1] the integrity of the remaining tooth structure. [2] the amount of functional load which to anterior teeth are subjected. [3] the morphologic development of anterior teeth.
The incisal edge of lower anterior teeth function across the lobes of opposing upper incisors
Considerations for posterior teeth Virtually all posterior teeth which have received endodontic therapy are in turn recommended for a cast restoration coronally. In turn if a coronal buildup is deemed necessary {core} for retention of the cast restoration, then further the decision for the need of a post must be determined. The prevailing considerations for posterior teeth: [1] greater functional loading of posterior teeth. [2] morphologic disposition of posterior teeth to splitting.

Design considerations for posts Diameter • retain as much dentin as possible in the roots of all teeth; increasing the diameter of the post has a minimally significant effect on the increase in retention.
